Htc 8525 - 8525, TyTN, MDA Vario II, JasJam General

Does anyone know if an unlocked 8525 will work on Verizons network? I've been using it on Alltel and Verizon bought them out now they want me to get a new phone. Sure hate to give this one up.

If the sim unlock has been run the there should be no reason why not...
Mind you I'm in Australia...

CDMA vs GSM
I went back and forth on this one. (and Welcome!!!!!)
Verizon here in the states is a CDMA (EVDO) system that doesn't use sim cards, GSM systems does. This relates to how your phone communicates on the network. Now willl a GSM phone work on a CDMA network, i think that it will. The SIM card in GSM phones supply the network with your PIM to access the network, it is tied entirely to the network not the phone. CDMA requires action from the carrier, and your access to the network is tied to phone not the network. You deactivate one phone first, then activate the second. You'll probably need to supply your IMEI to verizon and they'll load your access. Just a guess though, cause I've been with cingular/at&t since i carried around backpack sized mobile phones.
Does anyone know better?

As far as I know of, no. I don't believe it has a radio for the CDMA. Although you state you have used it on Alltel which I thought was CDMA...
What reason did they give for wanting you to get a new phone?

ATT 8528 on Verizon

Hi All,
I was wondering if I could use my unlocked 8525 with Verizon's net work if I switched to them? I'm not sure about compatability of the phone with Verizon's voice and data services and was wondering if anyone knew.
Thanks
I dont think so. Att and verizon use two different technologies. Att uses GSM and Verizon uses CDMA. Im almost certain tho a phone that is based on GSM cannot be used on a CDMA network. The phone will work on TMobile or USCellular. They use a GSM based technology. Verizon Sprint and Nextel all use CDMA. If i am wrong and you can use the GSM based phone with Verizon CDMA then someone please correct me. But i am pretty certain you cannot.
OK,thanks. Thats what I thought
Verizon does not have sim cards, is that correct?

Not that I've ever seen.
I know sprint phones have sim card slots, but they are not used, at least in the USA.
My guess is that CDMA phones can be used in the same way as GSM phones as far as switching sims to use different carriers, but the CDMA carriers in the 'states don't use that functionality (probably to keep a tighter grip on their sucke....customers and wring more money from them through phone sales/upgrades and extra services, like a data service to put on extra ring tones )
I know that I don't know much about these phones, but what of the setting inside of Settings/Personal/Phone/Band where you can select WCDMA as your network type? I've got an 8525 and it shows as an option, but I just don't know if anyone's tried it before.
CDMA and GSM phones are totally different. The only SIM based verizon phone that Ive seen its the Blackberry 8300 its world edition soo it can bu used through a cdma and also a GSM carrier. I would be interested if anyone knows how to say make a sprint phone capable of being on verizons network. That would be something different.
actually a sprint phone is capable of being used on verison network any cdma phone is. in short the way cdma works the subscriber info is assigned to the phone's esn by the carrier so only the carrier can change your phone with gsm the sim (Subscriber Identity Module) holds the subscriber info and it is assigned to a sim card id not a esn (electronic serial number) so all you have to do to get a sprint phone to work for verizon is get verizon to let it (GOOD LUCK WITH THAT) you would have better luck the other way around verizon is the pickiest co out there when it comes to network integrity and security issues they seem to think that letting people use any phone they want could somehow hurt their network

WCDMA is 3G. 3G on GSM systems is essentially a CDMA standard, but not the same CDMA as Verizon uses. It is not compatible.

JASJAR & Verizon Wireless?

Hi Everybody,
I have an I-Mate JASJAR and my friend who currently has a Moto RAZR, is on Verizon Wireless, but his phone doesnt make use of a sim card.
He is interested in buying my JASJAR from me, does anybody know if it is possible to get the JASJAR working on the Verizon Wireless network without a sim card?
Thanks
ChildOTK
that would be a no. Verizon runs off CDMA technology and the JASJAR off of GSM technology. so no the Uni will not work on verizons network
aaahh, ok, thanks. Didnt think of that.
Well a while ago I posted that Verizon was going to allow other phones on their network; granted they use CDMA protocol and our phones are WCDMA compatible, but I think it is the wrong frequency.
just my 2 cents

Roaming Symbol Problem

I just recently bought a Rogers HTC Magic, rooted the phone, and unlocked it. Everything seems to work completely fine. At the moment however, I seem to be having an issue with a Bell Mobility sim card. Bell's HSPA sim works fine, and I seem to be able to use voice and data ok, but the problem lies in that their seems to be a roaming symbol ("R") on my reception bar. Im using the phone in my local calling area which is somewhat misleading to me.
Im using MyHero 2.0.5 ROM at the moment. Does anyone know why this is happening? Thanks in advance!
Agreed
I'm doing the same thing. I'm running cyanogens roms and I get the same thing. Best I can tell is that this is normal on the magic. Just be careful if you live near the border like I do.
I figured this was normal too. I guess i'll try other SIM cards to see what they say as well, thanks!
Ya I also have this phone running on Bell, wish I could get rid of the roaming. It also asks if I want to connect once in a while too.
Shouldn't the romaing be dictated by the sim? I have a bell sim, on the bell network, why do I get the roaming icon? is there a way to change the phone so it doesn't think it's a rogers and not roaming or something?
Are you sure you have the Bell APN Settings and not the Rogers Settings in the phone?
Settings -> Wireless Control -> Mobile Network Settings -> Access Point Names
If it says Rogers you're Roaming on the Rogers Network.
I put in the bell APN. I don't think we can even roam on rogers network, wouldn't work. Either way, it's the Bell APN.
I don't have a clue as to the differences between Bell and Rogers sims... but I can tell you that my HTC Magic, on Rogers, with a Rogers sim (duh), running Amon_RA's most excellent RAv1.6.2H only shows roaming when actually roaming.
I was in the US yesterday and watched it flip from a Rogers tower to ATT. I was watching to make sure it was not using any data when roaming on a US network. The symbol, lockscreen info and the carrier listed in the status pulldown all were updated correctly.
It might have something to do with the ROM you are running. However I bet that given the phone came from Rogers, it has some carrier info buried somewhere that it is comparing to the carrier you are on (Bell) and triggering the roaming status.
If you disable data when roaming in the settings menu, what does it do? If it disables data, then the phone thinks it is roaming, which would support my carrier data mixup theory.
I will try a different rom on the phone. Unless someone knows for sure what I can do to fix this.
If you disable roaming there is no data, because once in a while it prompts to connect, if you say no, you get nothing. Sometimes my wife must accidentally hit no (its her phone, she probably says no cause shes not sure what it does). I just want to make it so she does not get the prompt ever (settings are all set).
I have a rogers HTC Magic (unlocked) I'm using a fido sim, it thinks its roaming as-well but I have only fido apn settings. It only roams with certain roms and radio's. I can use alot of roms eg. cyanogen,Hero HOFO 308,GYD 2.1.1 without roaming but when I update radio and flash cursorsense roms it thinks it is roaming. I have to enable data roaming in order to get a 3G signal. as a fido user I dial *#123# to see if I'm in my local zone zone. A fido tech rep told me that most unlocked phones indicate roaming because of the phones hardware programing. The hard programing of the phones checks the sim and sees that it is using a diff sim card and starts indicating roaming when in fact you are not. A rogers salesman also told me the same thing. He said as long as your carrier is displayed on your phone homescreen then you are good.
I have the AT&T Tilt, not running the AT&T ROM. I've tested a few different SIM cards on my phone and here's what I've found:
Rogers: Roaming works correctly. In Canada, no roaming indicator, in the USA, roaming is indicated correctly.
Telus & Bell (HSPA): Roaming indicator always on.
I've heard that this may be due to the SIM card listing more than one Mobile Network Code: 302361, 302653, 302657 (original Telus CDMA networks, not compatible with the phone or any kind of SIM-based network so it's uncertain why it would be on the SIM card), PLUS the HSPA network code 302880. It's possible that the phone is not reading that far into the list on the SIM and therefore does not know that 302880 is a home network.
Tilt 2 Roaming Triangle and telus
I'm on Telus and have a Tilt2. The original ROM that came with the unit didn't show the roaming triangle. I have attached some screen captures of the ROM. I've attached a copy of the registry (Remove the .cab it was the only way I could get it to upload).
I'm now running Jackos rom and it does show the roaming triangle.
Hopefully somebody can find where the settings are located and hopefully it's contained in the registry.
Have the same problem on the Stocks ROGERS 1.5 Rom. Sales associate said you should not get roaming charges since you aren't actually roaming and if you do, just contact your phone provider.
rogers htc dream unlocked now on roaming?
i also have a htc dream from rogers unlocked not rooted and my bell sims card works like my phone calls and my text but i can't get my data to work and when i click on the apns theres not thing and i am not able to adjust anything in there, if anyone can help it would be great, so pretty much the bell sims card works but i cant use my data and it says im roaming

If you aren't outside of Canada and you get the roaming symbol; they can not charge you roaming fees.
Roger and Telus PLMN Compared
I'm not sure if this will help,
I have attached a picture of the PLMN from a Rogers sim and a Telus sim
Maybe someone knows how to adjust the information on these lists.

The phone companies in Canada must be less uptight about unlocked/rooted phones
If you asked those questions to a t-mobile or at&t rep, they would straight up refuse to talk to you
American cell phone companies are still stuck in the "Ma Bell" mentality, where everything that touches their network must be under their control
anyone figure out a fix? I'm having these roaming issues as well on the bell network with unlocked at&t phone.
I have Same probleme Here, Bell on a AT&T Tilt 2 phone, Always get Roaming message.
any registry edit or mod available to make it work without these message ?

I searched around to a fairly moderate extent and I have found many people with the same problem, yet I can't find any resolution to this issue.
I'm not even sure where the issue lays. Is it with the hardware/firmware? SIM card? Windows Mobile? Is it the rilphone.dll? or maybe some registry entry. Maybe it's on the Bell network side?
Someone told me they put a Rogers SIM into their Fuze and it didn't show up as roaming, yet when they put a Bell SIM in, it's back to roaming. So what's the difference between Bell and Rogers?
Here's a question for anyone who has this problem, when you boot android does it still show as roaming?

How to flash HD2 to Cricket?

I tried searching everywhere and still no answers.
Does anyone know if it is possible to flash the Htc Hd2 to cricket or metropcs.
they are network providers, so i assume you mean unlock the phone to use them?
no flashing will not do that. you would need the network unlock code, however isn't metre cdma? if it then the hd2 cannot work on it.
Yes as long as the network uses GSM (sim cards )
So theres no way htc hd2 can be turned into cdma and be flashed to metro or cricket?
you cannot flash a phone to unlock it. as stated above you need the unlock code, you can get this from your network provider for approximately £15 just tell them you are leaving the country for a holiday and want to change your sim card to a local network sim card in the other country (to get a better rate). If you would prefer you can easily unlock your phone on the internet, again for aground £15-£20, just search on Google.
as for your other question about cdma im not to sure.
re: cdma i'm only 95% sure but i think you're out of luck, i think its a whole different hardware.

“Answered but not Perfected” Getting the Droid 2 Global to work on USA GSM

I was at at&t and we where unable to activate the phone even though the phone is capable. At&t said everything was good on there end but the phone just wont get a signal but it says it is on at&t.
Does anybody have any ideas how to fix this?
Have u unlocked the sim slot on the phone?

Quite a few people (including myself) on various boards have acknowledged having this problem as well. I got the SIM unlock code from Verizon but when I do a GSM network scan, nothing is detected. I know it has been escalated above level 2 support at Motorola and hopefully they will address it shortly. Here's another thread about it over on droidforums: http://www.droidforums.net/forum/droid-2-global/96596-droid-2-global-unlock-foreign-sim.html
Yes, I have unlocked the phone from the code verizon gave me.
I hope its a fixable problem. But I noticed when I use an active tmob sim the phone doesnt even say tmobile. But when I use an at&t sim it atleasts says at&t.
I'm very interested (as I'm sure many others are) in a resolution to this. OP did you call VZW global support and let them know you're having this problem? Hopefully the more they hear about it, the faster they'll have a fix

They where no help at all they said it was for foreign sim cards only and that at&t and tmobile where not supported. But they did say verizon was better than both of them combined.
If you feel like experimenting try this:
Go to dialpad, and enter *#*#4636#*#*
Click on Phone Information, and then scroll down to bottom. Set preferred network type from "CDMA auto(PRL)" to "WCDMA preferred" and see if that kicks it on ATT.
I'm 99.9% sure after looking through the user guide that VZW has restricted use of the 850/1900 MHz GSM/UMTS bands, even though the device has the hardware to support them. Most foreign networks use 900/1800 GSM and 2100 UMTS but AT&T/T-Mobile use 850/1900, which is why no one has had any success with them yet.
Hopefully someone can figure out a workaround.
EDIT: Just a US GSM restriction...looks like 850/1900 work abroad: http://www.droidforums.net/forum/dr...d2-global-south-america-first-impression.html

These where the results I got, so clearly it is getting seeing the network. Just not connecting.
Just got off the phone with Motorola and they said the droid 2 global was only for verizon sim cards and when I told them about the unlock code the guy didn't know what they where for. So another dead end. Another theory I have is that the stock verizon rom is blocking at&t so maybe if someone can flash another rom we can see if this is the problem.
Further proof the 850/1900 bands are locked: https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/57058/p/30,6720,7706
"GSM-based global services work only with a SIM card supplied by Verizon Wireless® or by another GSM 900 or GSM 1800 service provider. When you set your phone to use a GSM 900 or GSM 1800 network you may be prompted to enter a subsidy code. To get this code, contact Verizon Wireless."
EDIT: Looks like they're just locked in the US, not abroad: http://www.droidforums.net/forum/dr...d2-global-south-america-first-impression.html

If this is true why would they say it has the 850 and 1900 bands? I know its not a hardware problem, so if its a software problem there is a chance we can have a workaround. Or the locked bands might be because of the verizon rom.
I was able to put a new rom on my Droid 2 Global and although the rom was working since it was for a droid 2 the radio was not working properly. I was not able to force turn it on. I still have several more things I will try tonight.

Keep us posted!
This has been done before on Windows Mobile phones (CDMA HTC Touch Pro 2) and requires a radio reflash since the bands are locked in the radio firmware. I am hoping they will develop a solution for Android phones. http://rhodiumw.htc-unlocks.com/
Being that this the 1st CDMA/GSM (Tie if you count Droid Pro) Android device I would wait and see.

Good info, thanks
As from what I learned from previous devices the Droid 2 Global Verizon has a security locked radio. I have seen people unlock the radios from windows mobile phones, it is as easy as installing a .zip file that will unlock the security. I believe it is the same way with the Droid 2 Global. I will try to get this working but I don’t have much knowledge in the development field. But I do know you will have to be rooted. I have also spoke with a friend at Verizon, which claims that they did indeed lock the radios and there is a workaround. He said he was not familiar with this workaround but said it was close to the problem with the windows mobile security locked devices. I am calling this the official reason the phone wont work with US networks. This makes sense, and now that we found the problem it shouldn’t be long before we find a way around it.
Thanks for the info swangotp...that definitely sounds promising. Keep us posted!
subscribing to this thread... I know this is possible.
