OnePlus Two - HSPA+ and 3G Data Connection Problem - OnePlus 2 Q&A, Help & Troubleshooting

Hi Everyone,
I'm usually just a reader on XDA, but I have found a problem that appears not to have been solved and wondered if anyone had any insight.
Problem Summary
When in an area (or network) with only HSPA and UMTS (strong HSPA/UMTS signal, but with no LTE or 2G available), the phone will drop from H+ to 3G erratically, always dropping the data connection. Traditional phone calls are not affected.
Detailed Description
I have a OnePlus Two and have 2 SIM cards. My first SIM Card is with Bell Canada (Virgin), and the second SIM Card is with WIND Mobile Canada.
Neither Bell nor WIND operate a 2G network, so the lowest the service can fall to is UMTS/3G.
Initially, I didn't notice the problem because Bell also operates an LTE network, and there is no problem with dropping the data connections when on LTE.
When I switched to the WIND SIM card (which only operates HSPA and UMTS), I noticed a problem where the phone would initially connect to H+, begin downloading whatever is needed (say, streaming music), but then part way through the download, the connection would switch to 3G, and the data would effectively stop. Within a minute, the service would jump back to H+ and download some more, but this cycle would continue (H+ --> 3G --> H+ --> 3G... ), with no way of knowing 1) how long the H+ connection would last before dropping to 3G (usually less than 30 seconds), and 2) after dropping to 3G, how long before going back to H+. This problem makes the phone almost useless when there is no LTE.
The most obvious troubleshooting I did was move to locations of better signal but I quickly ruled that out, as nothing seems to remove this problem. Other things I tried was to: move locations in the city, reboot phone, hard reset phone, flash most updated version of Oxygen, unlock bootloader, root, try the HSPA Keepalive app, swap SIM1 to SIM2, and many other things.
I originally thought this was a network issue, but I put this WIND SIM in another phone and there was no problem in any way that resembled this problem.
I also ruled out this being a network-specific problem, as I have taken a trip with the Bell SIM to an area where Bell does not have any LTE coverage (only HSPA and UMTS) and the same problem occurs on Bell as with the WIND SIM.
I have found people who had this problem on the OnePlus One tend to recommend using 2G to stabilize the connection, but this is not possible on Bell or WIND. That solution also would not provide adequate data speeds.
Remember this problem only affects data connectivity, as 3G traditional phone calls have no problems.
Question
Does anyone know if there is a way to adjust the conditions when the OnePlus Two will choose to switch from H+ to 3G?
Does anyone have any easier suggestions?
Thank you all in advance, because this rendering this phone almost useless when there is no LTE coverage.

I believe your problem is that phone it's dualsim standby, that means only one modem that alternates signal for both sims, I think normal would be alternating from faster network to slower network on sim without data.
Having to change to g3 between sims theres something stoped in the modem and data connection is also stopped.
You have no problem with voice calls because other sim is automatically turned off and unreachable.
There's nothing you can do if you're forced to only 3g on both sims
By 3g I mean 3g or h+ which to my knowledge are the same
Hope I was helpful and not wrong or more confusing

Thanks, I will try disabling the second SIM to see if there is a bug with the dual-sim...
What it currently does with the second SIM is it either shows "R" for roaming or just emergency only, but perhaps there is a software issue so I'll see if disabling the second SIM makes a difference.

Though strange, this workaround fixes the issue. Thank you to fburgos for the suggestion!
So just in case anyone ever finds this issue creeps up on them, the solution is to DISABLE the SIM you are not using. It's not the most convenient workaround to swap SIMs, but the other SIM will be in Emergency Mode, so it really makes no functional difference.
On the technical side, it does appear that there is actually a bug in Android for a very uncommon network configuration. It will only appear in this exact configuration:
SIM1: Network has HSPA/3G only, no LTE or 2G to move to
SIM2: Network also only has HSPA/3G with no LTE or 2G
The non-data SIM does NOT connect to a roaming network (connects with "Emergency Only") - if it connects to a roaming 2G network, this problem does not happen.
The data SIM connects to HSPA/3G
Both SIMs are active
I'm not sure if this will happen anywhere else in the world other than having a WIND Mobile Canada SIM and Bell or TELUS Canada SIM
If anyone has insight on how to report this to Google, or someone else who can confirm my theory, that would be great!

Try this:
1. You need to make sure you have the correct LTE APN selected in mobile networks and LTE as preferred type.
2. Go to dialer and type in this: *#*#4636#*#*
3. Phone Information
4. Set Preferred Network Type to: LTE/GSM (PRL) - you an play with which one you wanna use but the one I said works for sure. on other roms I have" TD-SCDMA, GSM/WCDMA and LTE"
5. Now click TURN OFF RADIO and wait WAIT few secs. will that button turns to Turn Radio ON
6. Now TURN ON RADIO and wait
7. when u see the triangle for the signal is back, at least black , go down and lick SMSC REFRESH then UPDATE.
8. now just go back to APN settings and go into your LTE APN
9. Change Bearer to LTE

I have the same problem. Do you already have solved it?
I use only one SIM card so it is not a problem two cards.

really you do not have this problem? if no one knows the solution?

compared with my htc butterfly 2 and another low-end android, one plus 2 running latest Oxygen OS has serious connectivity issues. I compared the signals strength using same sim card in same location (including being connected to the same tower) and One Plus 2 keeps dropping the connection and has really poor signal strength. I have tried the *#*#4636#*#* and tried different network modes, but none of them are helping. Its a real disappointment that the basic feature of this phone is screwed up.
I have tried with CM13 as well. Any ideas if this is a modem version issue?

Hero, have to choose: Data/3G or voice calls, HTC reinvet the 90's!

Hi,
after having several missed calls going straight to my answering machine on my new HTC Hero. I was getting a bit paranoiac, so I've decided to test in/out calls.
Basically, 90 of my incoming calls were going straight to my answering machine. Out-call were about 30% KO
After several tests, to make sure there was a problem, I've decided to request for support from HTC.
Support told me that I should shut the 3g connection every time I would want to receive a call .
So I tried and Bingo, if 3G is activated, I get 10% of the calls, if I deactivate it 90% success.
So you'll say, I should be happy? Right? Wrong!
The main use of that kind of phone is to have a data integration, otherwise I would have kept my old nokia from 10 years ago..
Here basically, if I follow HTC idea, I should keep the 3g closed, sometime, I should switch it on to get my mails, thanks to the non true push capacities (ok this one is not htc) then wait for the sync, maybe force it , get my mails, and then, shut 3g back and pray that no Über important call would have been done.
Well that plain sucks!
Never had such a thing on my previous Data friendly mobiles, why should I accept it on the Hero?
If someone have come across this bug, cause it is a bug, how did he/she managed to fix it?
Thanks
works fine on mine....i suggest you are on a ****e network, or on only 2G where you are. that's what usually causes this.
I guess they suggested this because it sounds like your network hasn't figured out how to route calls properly on their network when data is active, and they dump it straight to voicemail when there is a data connection active.
not the phone's fault, the phone won't even know that the call has been missed, the network simply does not route the call through and sends it to voicemail instead.
i had this on O2 a while ago. went to t-mobile (who knew how to set up their network properly for data) and never had this issue since when i am on 3G coverage. if i'm on 2G signal and have active data then yes, i miss calls. but that's how 2G networks operate.
it's truly shocking how many networks out there have absolutely no idea how to set up their networks properly for data!
Well I wish it would be that, my signal goes from -63 dbm 25 asu(80% of the time) to -81 dbm 16 asu.
Just after my post, I called one of my friend working in carrier terminal validation.
What he told me was, 2 options:
- Same bug was on the htc cruise, bug got corrected after a fw update.
- Some of my carrier radio are buggy and 3g goes over gsm.(SFR/VOdaphone France)
I bet for the first option since I had the problem in various places since I didn't want to ask support for nothing and get busted for a " feeling and not facts" (did the test in 3 differend location 80 tests in total(I used to be a tester....).
I will update the topic if I get news about it

You shouldn't accept it - but most people don't have this issue!
It's unlikely to be a "bug" per se, because otherwise it would be endemic behaviour, so it's either:
1. Your physical device (get it changed!)
2. Your network.
In addition, just an FYI in case you've got the new Sprint Hero, but most CDMA networks (including Sprint) do not support simultaneous voice and data. I've no idea what happens in practice on Sprint, but I'd imagine if you were actively using data your voice calls would get diverted to voicemail unless Sprint automatically suspends data when a voice call is pending.

Dave
You're on SFR?
OUCH!!!!
Sounds like you have a nice strong signal, but is it 2G or 3G? (do you see a G, E 3G or H at the top of the screen?
if you see G or E, it's cos you're on 2G, If you get 3G or H, it's on 3G.
And yes, there were a few issues with the P3300 and the cruise, but they were mainly on Bouygues, not so much on SFR.
There's nothing known of on the hero, and as SFR sell the Magic, i would have thought they would have ironed out any issues already...
Hi,
I'm mostly in HSDPA or 3G.
I still have contacts with people at SFR (used to work there till recently) they might share a bit of info.
Idk if yours is CDMA or the GSM one but on mine (CDMA) under the mobile network settings, I have the option to switch the mode of operation to ether Hybrid, EVDO only, and 1X only. Now, I know how Sprint's network works, not sure if it's the same for any other networks but if I set it to Evdo only (3g) I'll miss all my calls because Sprint does voice over 1X. Hybrid mode does EVDO when you're using data and switches to 1X when you're doing voice/sms.

Regarding this and your suggestion that 2g and data will result in missed calls, Can you suggest how to avoid this happening? I live and work in the country and only have 2g, so have found quite often people have mentioned my phone not even ringing- straight to answer phone. This explains it.
Nice to know, but annoying if I can't solve it- I run a business and my phone is very important.
Cheers,

i have sprint as well and when someone calls you when youre running hybrid, you should not miss calls. you will get disconnected from the internet when someone is calling though

Hi, I'm on hybrid
that is what i hate about hero, it is really great except for the fact that it switches from 2g to 3g without notice. i want it to be permanently stuck in 3g for faster downloads and mms, but when it uses 2g, i cant send and receive mms and surfing the web is slow as heck! im still looking for an app that would permanently put the device in 3g just like with winmo it which you can use wcdma ONLY.
cheers!
If you use AnyCut, you can create a short cut by selecting:
New Shortcut->Activity->Phone info
This will create a shortcut on your homescreen which beings up a hidden "engineering" screen on which you'll find an drop down for "Set preferred network type" where you can select WCDMA only.
Regards,
Dave
alternatively, open the phone app
dial *#*#4636#*#* and select phone info
scroll down and set it to WCDMA only.
does the same thing but saves installing an app.

That is not specific to the Hero. The fact is, every carrier's 2G network has better coverage than their 3G network. When the phone cannot detect strong enough 3G signal, it jumps back to 2G network. The idea is that slow data transmission is better than no data transmission at all. Many smartphones have the option to lock the mobile network to 2G only. One advantage is that it gets better reception, and another advantage is longer battery life (the 3G chip eats battery much faster than 2G).
If you instead lock the phone to its 3G network. The first thing you will notice is that battery life is significantly shorter. And chance is that you may be getting very spotty reception, because you are not allowing to phone to switch to 2G when it gets no 3G signal. When there is no 3G signal, forcing the phone to "3G only" mode won't give you faster download, it gives you no download.

true true. i usually charge my phone everynight though. problem that i have with 2g is that i cant send and recieve mms and yeah data connection is slow. in our place 3g signal is ok. i also lock my topaz for wcdma only. but it is ok that it switches to 2g in low signal areas.
Thanks!
You actually use mms?
Wow, they do exist.

What NOM1 Networks are there in the UK? I only get 2g in my area (booo) and could do with an operator that works right. T-Mobile forums suggest they still have an issue
Hi
I've checked it with Hero running in PlusGSM in Poland.
Regardless if I select 2G/3G or even "WCDMA preffered/GSM Only/WCDMA only" setting the phone is not available for incoming voice calls during data transfer. Every time when I start internet connection (example: SSH session) I'm not available for incoming calls. At this site I do have both strong 2G and strong 3G networks.
I would like to mention that a few days ago I've swapped Samsung SGH-i600 (WinMo 6.0) for HTC Hero - so I'm using the same SIM card in the same network and the same place. SHG-I600 was able to perform both data transfer (on 2G) and voice (on 3G) on the same time. HTC Hero is not...
I wonder if this is 'feature by design' or a bug in software?

3G on and Off

So, i have bugged folks on this forum about getting 3G to work on other carriers, and it turns out - it does work! At first i found out my settings were set to GSM only, but now i also found this weird inconsistency possibly a bug.
If i have Data Off after using 3G or GPRS for some time, when i turn it back on, phone would not connect to data service. After enabling it will simply time out.
I found that if i switch from GSM to WCDMA, and than back, 3G network would connect and work.
I don't know if it's specifically my phone, or a bug, so i'm just throwing it out there.

What carrier are you getting 3G to work? I doubt its working if its anything that doesn't run on tmobiles bands..the icon will come up and stuff but your either getting edge speeds or not getting any connection. I've had this phone show me 3G with full bars and just time out.. I can eveven put in a sim with a sidekick plan or other data plan and it shows 3G but it does not work
Well, i'm overseas and i have used it on Russian carrier Beeline and carriers in two other countries. Now, i do set my connection to WCDMA only, which gives me 3G icon. When i set it to GSM only, i see GPRS icon show up.
So, it does work, i use fring, online radio, google maps. But as far as speed concerned, i have not tested it.
Just ran a speed test using Speedtest.net tool, I get 3951kbps download, and 655 upload
thats 3G

Fixed. National roaming not working. Norway

Edit: writing it down helped me understand that i actually never activated "2g or 3g or 4g" in elixir2>information>telephony>turn 4g on.
So this was how i got onecall to work properly, in case there's other Norwegians with the same problem.
___________
In areas where my provider doesn't have reception it uses another provider. My phone then shows that it's roaming and that it has data connection, but in reality it doesn't, i can't access the net. Roaming is activated, the apn of my provider is setup correctly. My provider uses 2g and 3g, the other provider uses 4g as well. When the issue appears it doesn't help to turn on and off airplane mode, doesn't help to turn off and on obile data or to reboot the phone. The problem appears no matter if I choose the other providers network manually or let the phone do it automatically. I tried every possible setting in elixir2 regarding "preferred connection speed - 2g only, 3g onlyn 2g or 3g or 4g and so on.
Anyone with a similar issue on this or a different phone and a possible solution?

3G Data Not Working

Problem has been resolved. See my final post in this thread.
Long time lurker. First time poster.
I am having problems getting 3G data on my new phone.
Last week I activated a new Moto X Pure Edition on the Sprint network via MVNO Ting. The phone appeared to activate just fine. Voice, text, LTE, Wi-Fi, and 1x data are all working without any obvious issues. Phone is pure stock.
3G data is not working. If I set Preferred Network Type to "LTE (recommended)", mobile data works on LTE but if I travel to an area that has not yet been upgraded to LTE, it will not drop back to 3G. Further, if I choose 3G as the Preferred Network Type regardless of whether the phone is connected to an LTE tower or a non-LTE tower, I get no data connection. Same for Global - no 3G connection.
If I choose "1x" as the Preferred Network Type (whether in an LTE area or not) then the phone will establish a data connection. The phone reports this connection as 3G in the status bar but the speed is so unusable that I doubt it can be a 3G connection.
I've done a carrier wipe, updated the device config (profile) and updated the PRL, all several times. Nothing changed. I've also done a factory reset which also did not help. I did not have any issues with my Nexus 5 which the MXPE replaced. I have since reactivated the Nexus 5 with a new number while troubleshooting this problem and it reactivated just fine. No issues at all.
Questions:
1) SignalCheck Pro reports that mobile data is "unregistered" when trying to get 3G data. Is registration of 3G data tied to the SIM card or to the MEID of the phone? Trying to determine if the registration problem lies with the SIM, the phone, or the network.
2) Why would I be able to get a 1x data connection but not 3G?
3) Ting is suggesting network problems may be playing a part but I'm not sure as the problem has persisted through several cities around west Texas and eastern New Mexico and throughout Lubbock TX which has many cell towers. Is there any way this could be a network issue?
4) Is the SIM for the MXPE compatible with my old Nexus 5? I'm wondering if swapping the SIM into my N5 will help to diagnose the problem.
5) Is anyone else with a MXPE having issues with 3G data?
This one is puzzling and I need some help from the gurus. Thanks much.

Bump.
Swapped SIMS with one sent by Ting to verify the problem wasn't with the SIM. Still no 3G.

Yes..i am having the same issue..with vodafone in india
Update. After two Moto X PE phones, numerous factory resets, much research and testing, there is now a work around to this problem. The problem does not appear to impact any phones on the big 4 networks. It only impacts phones on a Sprint MVNO.
There are now known eHRPD issues with Sprint and their MVNOs. The work around solution is to disable eHRPD. Sprint is working on changes to eHRPD that may resolve the issue permanently. Thanks to Ting for their persistence in helping get to the bottom of this problem.

Final update. Earlier this month Sprint released some changes to the way eHRPD handoffs are handled and that resolved my issue. My Moto X PE now works as it should with no workarounds necessary to get 3G data.

There was no update pushed to the phone and no changes to the phone. The fix was on the network side.

So why not work 3g? Is the problem in cell operator?
^^Sprint had some issues with 3g (ehrpd) on mvno's. It would work if forced to evdo, but not ehrpd. Sprint made some changes to their network so this now works correctly. It was a network side issue.

weak signal strength

my mi a1 signal strength is very low.drop frequently from 4g network to 3g or even in 3g network have low strength and voice call doesn't have proper quality.i compare a1 with my other phone in the same room and the other phone doesn't have this problem for example if a1 have 10-11 asu signal in 3g network the other phone have 15 16 asu signal strength.so my questions:
1-anybody else have the same problem and if there is a solution for that
2-this kind of problems can be fix by software update or is hardware problem and something related to design and material of the phone and can't be fix by update?
My problem is Same
Same problem in my phone after december update no improvment
mine never have any network 4G or 3G issue.. it's working fine indoor an outdoor

Try putting the SIM in the second slot.
Worked for me....
I got a network issue too and 2nd sim doesn't stay to 2g only if 1st is selected as data. Consuming most of battery due to this. This happened after the first update. Please check of anyone else too has this :/

i think maybe a little bit better but the problem didn't go away.i compare every network,in 4g and 2g network a1 behind other phones but in 3g network has good signal
does anyone know if this kind of problem can be fix by software update or it's a problem with hardware or design (maybe unibody design blocking signal)of the phone?

i didn't understand what was the problem exactly but in my phone you can select one of two sim for data and the sim select for data automatically change to 4g/3g and the other sim will go to 2g only. if you have two sim active it's normal to drain battery a little more but i can't complain about the battery i think it's good overall

my secondary sim can find 2g or 3g network but no 4g.4g only available to data sim.maybe VoLTE call can be the reason?(my carrier doesn't support VoLTE call)
try this:data sim in 4g ok.the other sim is for call only.dial *#*#4636#*#* then go to phone information set preferred network type to GSM only

This changed the primary sim to 2g and for 5 min secondary sim found 2g and again it was on 3g. I have weak network for 3g 4g at my place, due to phone switching to 3g 4g I get higher battery drain. My old phone kept my secondary sim to 2g only. I think A1 has issue keeping phone to 2g only

for me working.this 4636 menu will change the sim selected for call and SMS (you can select sim one or two for call and SMS) to 2g and the other sim(data sim) will not show in menu. I select that GSM option and several hours later still on GSM.but after that don't go in cellular network-->network operators and search for network maybe that can change setting to defualt.you can check if you are still in 2g mode in 4636 menu or in setting-->about phone-->Status-->SIM status

Ok I got it , I don't use secondary sim for anything else then receiving the call. So i didn't make it default anywhere. After making it default to calls I could see the option in 4636 for secondary sim. So this solution doesn't work in my condition, I don't know why the just keep the secondary sim to 2g only . I have reported this couple of time but no changes. Hope they find this issue in Oreo update
