Phone connection dropping

My P3600 phone goes insane sometimes, and will not dial out (hangs up immediately after dialing without ringing), or hangs up within 5s of me answering. Does this happen to anyone else, and if it does, what do you change to fix it?
jchap2k

Same here...
I don't know why this happens...

Me also
Running the new HTC official ROM, I noticed it first with the upgrade, I make a call like voicemail from the attention prompt and I put the phone to my head and the call is ended after like 5 sec. I though at first my ear was hitting end but tried it without moving the phone anywhere and it still will randomly end calls right after I try to make them... tried disabling smart dialing and that seemed to work at first but I could have just been lucky because it didn't keep working... anyone else besides us three?

I also lose calls or conversations break in the middle. I went to HTC service and thet recommended me to change the SIM with a newer one. I did that today and I only lost one call so far (but I was sending an MMS while talking to a customer service rep so it might be related to that). If things improve I will let you know.

Mihaig, any news about your SIM change as connection dropping solution ?

I tried turning off UMTS (using only edge), and so far I have not had any dropped calls/immediate hang ups. Would getting a new SIMs card allow me to turn back on the UMTS bands?

I did have a sim card go bad that had to be replaced. The phone wasnt dropping any calls, then all of a sudden just couldnt find the network. My new card has dropped a lot of calls lately.
But i'm not too worried, my service provider thinks its there network fault and I the complete call is free as long as I phone the person back.
Anybody have a 'settings' solution, I would be very interested.

Well, so far no more dropped calls after turning off UMTS. I wonder if a new SIMs card would help in this matter. (mine is only 1 year old though).

Only with Car Bluetooth
There are some gaps in the conversations when I use the Nokia Carset bluetooth but with the P3600 itself no problems so far (just 1.5 week old). I do have some problems with the SD card, ones two days the info is corrupted and I need to format the SD card.

As far as I have found out, the problem has to do with 3G, the 3G hasn't got coverage everywhere ( at least here in DK ) and when the phone switches, it sometimes lose connection for a couple of seconds. Switching off the umts did the trick for me, no more hang-ups or lost connex, but then again, no more video-calls or streaming, so it's a choice... :/
Hope the next update will fix this, if there is a next one... P

There is a known problem with many service providers and HSDPA. If you have the phone on automatic while in 3G mode, when your phone connects to data the phone will switch to HSDPA just for the data transmission (if your provider supports it), during the transmission calls are not received and usually sent to voicemail. This doesn't happen with all providers, but it does with many of them. You can turn off just the HSDPA and not the 3G with this tweak program http://www.fit4cat.de/thread.php?threadid=263. On my phone I have no problems with normal 3G, it is just HSDPA that is the problem.

Hmm, I already tried that program but I still had the same problem even after turning off the HSDPA only. It never happens when UMTS is off completely though. I figure when I want to use the internet I will turn UMTS back on and when I just need it as a phone I can turn it off.

Sorry folks, dumb question: where can I turn off UMTS in my trinity and only have EDGE enabled?
Thanks for your help...
mfg OK

Press the green button to start the phone, then Menu/Options. Select the 'Band' tab and change the upper box to GSM.
Leave the lower box at 'Auto'

I replaced with a new Cingular/ATT 3G sim and still the same problem... I'm going to also try to turn off UMTS to see if this fixes it... mostly I notice when calling voicemail from the notification tab... Oh yeah, it now says ATT as my service...

I have this problem, on the Orange and T-Mobile network, with WM5, and WM6. Have the latest radio, the works.
Bit of a joke that this happens to be honest.. a phone that has 3G/UMTS but that won't allow a certain number of calls when it switches. Pretty fundemental flaw if you ask me!
I've set band to GSM, let's see if it fixes the problem. Will download the aforementioned hack this evening.

Ah, I see it's the operators problem, not the phone's. Flipping amateur of orange not rectify this before shipping..
I've used HTweakC to disable HPSABCD(sic) and will see if the problem stops.

Not a SIMcard problem
HI Guys!
I work in a Mobilephoneshop for a Network Provider, and i had the same problem.
The first trinity that arrived in the shop was mine
And this little bas... droped many calls.
I talked with the tecnics from my prov. first we changed the sim, but same problem. Reflashed Rom same problem.
It has something to do with teh HSDPA, evrytime my trinity connectet them, the calls was dropped, the bad thing was, we have a HSDPA antenna in teh shop
Only the change of the devise worked.
Hope was helpfull and sorry 4 my bad english!
mastah

See above, use HTweakC to disable HSDPA, but leave 3G enabled.

Your SIM card does not allow a connection to this network

I'm curious to know if anyone with a non t-mobile g1 experienced the same.
My phone was working fine this morning until it stop being able to register on the network with the above error. The only thing I did with it this morning was to put on a screen protector. I doubt it's related
A reboot in recovery mode and a wipe fixed the network registration issue so I guess some data were corrupted.

Hi.
I have the same problem now. Have tried to hardreset but still No service..
Can you help me??

Just get a new sim card

I have the same problem now - but it is extremely frustrating and I have tried, since I first wrote what is below to downgrade - but cupcake will not let me.
I have an unlocked - but also unrooted G1. I use it in Europe and in the US. While in Europe I got the message to upgrade and without thinking I did. Then while in Europe I could no longer use the phone as a phone. The update went fine and I had ‘cupcake’ but any SIM I put in (T-mobile, BASE etc) there was no signal and when I went to do it manually I got the message “your SIM does not allow a connection to this network”
So I did a hard reset, but then I could not get pas the start screen since I had no data connection (but I did seem to have phone connection again.
In a layover in Atlanta I tried again - I was able to log in and set up and all was great and good. I should note that I have an old data plan and use an alternative APN to access data. This worked fine in Atlanata where there is 3g connection.
Back home no win Florida… no phone service - same as in Brussels. same message. Worth noting - there is no T-mobile 3G service where I live.
After thinking about this for a while I am wondering if somehow I did not get the correct or full radio update…
if this is true - do you have any idea how to remedy the situation or how I would know if this is the problem?
I appreciate any help.

I have the same problem, any news about this?

I had this issue randomly about a week ago. Reboots didn't work, and I really didn't want to go through a wipe/re-flash. I called T-Mobile, they had me reboot [after I told them I had already done it] --- they ended up deleting me from the network and reboot my phone again, which apparently re-registered me on their network.
This is on T-Mobile US (SW Ohio to be specific)

Does anyone has any news about that? I was told that this might be a radio issue, so I tried to downgrade my celphone to version 62.33.20.0H_1.22.12.29, (using fw 1.0 too), it worked for some time then suddenly it gave me the same error that my sim card it's does not allow to this network, so I forced, again, to my network and the same message appear, I tried this sim in another celphone and worked, I tried another sim on my G1 and it didn't worked, this celphone was working when I lived in the US, but here in Brazil it's not working just like there.. my guess is that the Radio in other countries has any bug, does anyone here was able to fix that? any further advice?
thanks.

weird, i have this issue tonight on one of my unlocked g1's that would normally be working on ATT.
I'll update this post if/when I find a cure.

I've been having the same issue of and on for a couple of months now with a G1 on Dutch T-mobile with dutch T-mobile SIM card, which is odd. Running CM mods so maybe the fact that i'm runnig non stock fw causes this?

I get this problem from time to time. Almost never around town where coverage is good, but when I'm on the road in a lot of places where coverage from any provider is poor this happens, especially if it keeps having to switch back and forth between roaming and not roaming. I even get this on T-Mobile and they are my provider. Usually a reboot fixes it, but not always. I've never had it last more than an hour though.

Try reflashing the radio on your phone. Sometimes this helps solve odd connection issues.

according to my tries, this isn't related at all. i'd like to check in on this thread and see a known fix instead of maybes.

Had the same problem
I had this problem about a month ago, apparently simcards can go bad after a while; I had the same simcard for 5 years and it became unreadable. I went to a t-mobile dealer, bought a new simcard for $20, and I was finally able to get my connection back. It's a bit of an expensive route, but at least I didn't have to replace the entire phone.

my att sim is 4+ years old, but works fine in all but one phone in question, with the above error. also, I have a brand new tmo sim that throws the same error, only on that one phone- which leads me to believe its not a sim CARD problem at all.
all my phones are unlocked, in case of weird problems with any gsm carrier.

Looking at your sig, is this one of the phones with gnav? Because some of the earlier techniques of installing gnav have resulted in a "no service" signal. If it is one of the phones with gnav, try pushing the old build.prop files back into the phone.

gave it a shot, used the normal build.trout... and same results. surely someone at tmobile is familiar with this problem ?

Same issue.
I am running cyanogenMod-4.2.12.2 with radio v. 2.22.19.26I on a t-mobile mytouch. I will lose service and the phone will not automatically reconnect to the network. When I manually select my network (wind mobile) it sometimes connects fine and sometimes I get a "your sim card does not allow a
connection to this network" error and must reset. I found this thread code.google.com/p/android/issues/detail?id=2845 where dozens of people running all different hardware (G1-hero) and all different software (stock cupcake, cyanogen, etc) all experiencing same problem. It seems this problem is happening regardless of the network (T-mobile, vodafone, orange & wind mobile). The problem seems to be happening through all different variables. Changing sims does not seem to fix it. Anyone have any ideas, this is very frustrating.

I've seen this issue as well, with the new Canadian provider Wind Mobile.
The issue seems to coincide with new towers being added onto the network. There are minor service disruptions that result in the network being temporarily screwed up. Going into and out of airplane mode seems to fix it every time.
Also note: These minor service disruptions do NOT ONLY affect my phone, but others (different brands) as well.
They've gotten better at adding towers without blowing up the whole network. It started out happening a few times every day. In the last week it happened only once.
Funny observation: When this happens, the DATA SERVICE recovers automatically, even though the signal gauge remains in X-no service mode. This part is probably android and/or dream related.

It is related with network
I've started to have the same issue tonight. I've rebooted several times and changed the SIM card with another from another operator but nothing helped.
Then i remembered that since I bring this phone from Belgium to Turkey, the regulations in Turkey requires the phone to be registered with its IMEI number to the telecomunications supreme board.
Altough i had initiated the registration process months ago, i thought that there may have been a problem with the registration, so i checked the boards web page.
It turned out that my IMEI is not registered and this most probably is the reason for the not allowed connection.
Tomorrow i will try to reach the board officials and i hope it solves the issue.

do you know what happened? i having the same issue right now and cant seem to find a way to solve it..

my location doesnt update, weather, google maps, bing, etc

searched the forums with little info about my situation, other than that it seems to be happening to a handful of others.
havnt changed any settings or added apps or anything to my phone for several weeks if not months. i am using the cell evo v1 rom. 2.11.50.20 radio. i dont have a proxy server running.
for the last 2-3 days my location has only updated itself once. google maps cant find me, as well as bing. manual update does nothing. soft reset does nothing. wifi connect does nothing. i can get on the internet, sms, mms, etc etc.
i read on tmonews.com that tmobile was turning on HSPA+ in my region in the last couple days, along with 18 or so cities around the US, can this have something to do with my problem?
not sure what else to do...cant find any info.
thanks

I'm having this problem now as well. Been working on it for a couple days. T-Mo has had HSPDA+ here in St. Louis since before I got my HD2, so I don't think it's due to them adding it to your region.
Strange things I've noticed so far:
It works if Wifi is on, but not connected to a network.
It works if you are connected through EDGE, but not 3G or H.
The AGPS server IP address in the registry is a private network address: 10.something. If someone with a stock TMOUS rom can look in /HKLM/HTC/SUPD AGPS/ for the Server IP key and post the contents, I'd like to know if it's the same.
These issues are the same as everyone with different devices has been having for a while now, but the older phones with the issue seem to work in some areas without the wifi and edge workarounds, and not others. Mine so far works nowhere without the workarounds.

Try going into the manila slider and on the weather tab press menu > Enable my location

^ that isn't even an option for me on the manila slider anymore for some reason. I disabled the gsm and ran on edge and it was able to locate. as soon as turned gsm back on it wouldn't do it again.

bump, anyone?

Smartass answer in 3...2...1...
Maybe you should move to Denver. Colorado is beautiful this time of year.
Kidding aside, how about trying a hard reset?

from what i've seen on threads somewhat related to this, hard reset is a 50/50 shot. if i'm going do a hard reset where i would have to redo all of my settings and such, i'm just going to wait until the new version of the cell evo rom comes out. which is supposed to be soon.
i really dont understand what would cause this to suddenly happen. especially since it still works on edge. i tried wifi once and it didnt work, but i think i had my network connection still on. but regardless, this is pretty rediculous.

If you've traveled anywhere, your radio may be 'stuck' on a distant tower. This has happened on a couple of our phones and the tmo folks had to do a push/release/unstick type of signal to the phone. May be worth a try.

^ok, i called tmo tech support. mentioned about the possibility of sending me a reset signal, she said that was a possible scenario, but she was pretty confident that it was because my sim card is an older model sim card. claims that the sim card in my phone wasnt designed for 3g services, and any sort of change in the network (like them adding HSPA+ like i mentioned above) could interfere with the connections. she said the fact that i could do this on edge and not 3g is a dead giveaway that the sim card is the problem.
she said they are in the process of trying to get people to go to the corporate stores and switch to the latest sims. apparently this is happening to a lot of people, but the sim should be the fix.
i guess i'll shoot up there later on after work, or tomorrow, and i will give you guys a follow up on this.

Actually that does make perfect sense, and I suspect you'll find it clears up your problem. In fact, for anybody else that finds this thread, I suggest you try that step before other alternatives like hard-reset or ROM flashing.

yep, new sim card did it guys. i would recommend anybody having any connection issues to see if your sim cards are up to date.
edit: it was working before. now its only updating on edge again. not sure what to think or do. going to wait and see what happens when the new rom I use comes out.

any other ideas on this guys? new sim card only worked for a few hours. back to only updating 'my location' on EDGE and WIFI. pretty damn annoying. thinking about calling tmo support again to see if they'd send me a 'reset signal', but with having the new sim card you'd think that it wouldnt be a factor anymore, because i'd imagine it's already been reset.
the only other thing i could think of, and thats what tmo would probably tell me to do, is a hard reset. i'm sure they wouldnt be too happy with having a flashed rom on there either (not that i would tell them anyways).
if nobody has any other ideas but a hard reset, i'm going to wait for a couple days until the new release of the cell evo rom.
thanks

Yea. That weird problem hit my second HD2. I bought one 2 weeks ago and after your post paid more attention and of course noticed my location being Denver....
I deleted all preset locations and added custom one. It updated only once, right after location was activated....
However, wife's phone HD2 which was purchased on 3-24-2010 or original release date does not have that issue, ROM was updated to 2.13 a month ago or so...
Here you go...
Two of the same phones (supposedly), with the same stock ROM, with the SIM cards acquired about 5 years ago. One shows weather update without problem, second (newer one) has that dreaded nag....

I had a similar issue where the weather would only update once then freeze and never update again. All other 15 location updated but not my location. This was normal for stock and 2 roms, then I used energy rom and it now works. huh? Go figure.

Strange...I'm in St. Louis, as well...MO, that is...and it is working fine for me.

Try downloading the HTC connection wizard. This has fixed connection issues I've had before. I know Tmo has 3 networks to choose from MMS, Data, and Internet. I beleive you want data and may be your phone is selecting Internet.

ya that didnt work. either. still does it on edge though. the cell evo rom update will hopefully be here soon, if that doesnt fix it, the i'm not sure what to do.

I also have the problem of weather for my current location not updating (and the location not updating either). I have had the phone for almost a month and it updated regularly, although I noticed an occasional lapse for an hour or two. Following the suggestion by misticninja, I switched the band to Edge and I was able to update the location and weather. When I switched back to auto (3G), the update failed. It occurred to me that when I am in my basement office at home, I get Edge, not 3G. That may be why I got updates there. But I am sure it has updated in the past at my work location where I have very good 3G. Is this an HTC problem or a T-Mobile problem?

You need to have your location enabled. Go to settings tab the location and then click on enable my location.

How to fix mobile data problems on your OPO!

Well, this is probably the first post I ever posted in one of those forums but I was pretty sure some people might get the same issue so I just thought I'd help out.
I received my One a few days ago, went through hell and back to unlock the bootloader after I already set everything up the way I like it, rooted the phone and updated to XNPH33R and everything was a beauty until I noticed my network acting up. At first it was just the internet connection would drop every now and then then the voice calls started dropping more randomly. I must've flashed my phone like 10 times just to make sure I covered everything.
Then I decided to check the bands used by my service provider, found them on a link on the GSMArena website.
After that it was a matter of setting that on my phone, so I searched online and got this code, *#*#4636#*#*, which should take you to the service menu, there you should be able to make a selection as to which band you want your phone to operate on, as well as the connection type. I set mine to my countrys' band and the connection type to WCDMA/LTE, after that my connection was H+ and it didn't drop for 24 hours now, not even once.

Oh and the oneplus one is a piece of art, literally.

So it sounds like it may be an issue with your SIM card. I know what you are thinking, what could this possibly have to do with the SIM, on another phone I had, an LG G2, also running CM11 nightlies, I could not get an LTE signal at all on the phone. I took the sim card out of a nexus 5 which had LTE signal with no issues. I put the SIM back into the nexus 5 to see if it was the sim card, and I got an LTE signal in the nexus 5. Tried flashing different radios, flashed back to stock, nothing was working on the LG G2. FInally somebody suggested that the SIM card may have "tied" itself to the nexus 5, I was like that is BS I have never seen this before, sim cards are meant to be moved around to different phones, kind of the whole point of their existence. After a day or two of trying everything I could, I finally gave in and went to see if it was in fact the SIM card that was causing the issue. Lo and behold, new SIM card activated for my account, G2 immediately received an LTE signal. I know this isnt the exact issue you are having, you are having issues with dropped data, but I still suggest before you do anything else, try to get a new SIM card and see if that resolves the issue. On the G2 I went into that same test menu and when I would select LTE it would go right back to WCDMA preferred, would never stay on LTE, once new SIM card in I was able to change between the two. Just my two cents.

lost cellular data

So, when I woke up this morning I noticed my cell signal strength icon was one I haven't seen before. I tried rebooting and toggling airplane mode. I also verified that my sim is working in another device. I attached a screen cap with the icon.

Noticed something similar with mine. I had to turn wifi off, restart to get LTE data (verizon) then turn wifi back on. If restarting with wifi on the LTE data doesn't register.

that didnt work for me
update: had to factory reset, looks like verizon doesnt like that essential ph1 wont take all their bloatware, etc. might have to return the phone if this keeps up

My data connection has also become very erratic - and I've lost voice+data (VoLTE connectivity) wholly yesterday. Worked fine with the activated SIM from my HTC 10 from the 31st to yesterday.. Now, not at all, I've not been able to restore it since.
Really don't want to return it, as I really like the phone, but this has nexus 5x issues written all over it for long term use...
Hoping essential can get a certification and an agreement with Verizon before my return window is over (or at all)..
Pretty disappointed in Verizon here.
Sent from my PH-1 using XDA Labs

Same here, another issue is that essential shipped my phone and within a day i had an email from essential saying that verizon certification is still in progress. verizon will probably not certify it with their system unless essential lets them install their monitoring crap all over the phone.

The Nexus 6P didn't have the bloat and worked fine.
My PH-1 works fine including Enhanced 4G LTE Mode.
What do you have selected for network type?
I have the first one selected because that's the only one that includes the various CDMA protocols, EVDO and LTE.
I see the same connectivity that I had with my Nexus 6P.

i have global selected, as it covers everything the phone can connect to. i had the first one selected but it wouldnt show the lte+, just regular lte. i also have Enhanced 4g lte mode on. it just happened to lose service earlier today. if it does it again, ill probably return it after a visit to vzw

I have the same settings as you, I had functional "enhanced 4G LTE" for the first 4 days as well... That ended yesterday morning abruptly, and I'm not able to bring it back.. There's more happening here.. How long has your device been on the Verizon network? Only a hunch - in a few days you won't have "enhanced 4G LTE" either, even though it'll still be checked, and provisioned for it.

Cellular network is not available
After 7 days my phone won’t make calls I can only use data I’m on sprint and it was working fine until today I call sprint they had no answers at all I email essential no answer now I can only use WiFi calling while home and axx out at work

So, upon further digging I found a place to look at some more in-depth stuff relating to signal stuff. I did some fooling around and switched it from unknown to lte/cdma/umts auto (prl) and it seemed to work after a few moments of time. Though it seems have gone back to t he unknown state again but is working normally for me now, so maybe it was changing states and then a reboot?
How I got to this screen was by punching *#*#4636#*#* into the dialer, and went to phone info

I'm having a similar issue. I often lose my signal. I will have the full triangle/bars but no label of the signal(LTE+/LTE/3G/1x/etc....) and no cellular data at all.
The only way I can get it to return is to restart the device. Happens a few times a day, can't be 100% sure why, but it often appears to be when switching from WiFi -> Cellular only.
I have Verizon, I have had a Nexus 6 and then a Pixel XL for the past 3 years, never once had this issue.

I had constant disconnects and lost of service with my Tmo sim. Tried my Xfinity (VZW) sim and it was great until this morning. Complete lost of service. Airplaned mode on and off, connected to old school RTT 1x.... lol This phone's cellular just plain suck for a lot of us regardless of carrier. Not sure if we just have bad phones because apparently there are those who claim they have great service and connection.

I'm having this problem with Verizon. Seems like if I'm on wifi for a long period it only connects to 1x and putting in airplane mode and stuff won't get it to re-connect to to LTE. Only a reboot seems to fix the problem.

Necro post here but chiming in that I have the same problem with Verizon LTE. Happens when I'm moving long distances in car too. Suddenly just drops LTE and only a reboot will bring it back.

You might check out my post from the Oreo Beta thread... I was having some goofy signal issues early on which I've pretty much cleared up by doing what I mentioned here. Someone touched on it briefly earlier but only mentioned monkeying around with the settings, said nothing about picking up a new PRL.
I state this in that post too, but just in case: I offer this with no express intent of warranty, if you screw up your device, it's on you.

I just changed it from global to LTE/WCDMA and I got LTE back almost immediately. Was weird and global had been working for me for awhile now so not sure what happened in the past few days...

I had, right after writing this, tried *#*#4636#*#*
I set it to global as instructed in another post. The next time I drive a distance in the car I'll have to see if I have the same issue that only a reboot would fix again.
Thanks

I had the same issue and I resolved it a little differently than the previous posters. I turned on adb debugging and logged into adb shell and user-disabled com.redbend.app. This stops the Sprint oma-dm service from running. After doing this I no longer have the issue of my device not reinitializing lte after sleep or 3g.

I have essential on vzw but my only issue is my device won't connect to 4G. If I change network to LTE I get full 4G service but I'm unable to make phone calls. Went into vzw store and they told me you didn't get the phone from us so we cant help you. Day 14 fml

On Xfinity mobile, I had similar issues. Great LTE but sometimes calls just don't work at all. I mess with various settings and it'll work for a bit then so again. Gave up and ported over to Sprint for the free unlimited year which is still probably not worth it. Should've kept with Xfinity Mobile. Lol
