Got my Oneplus two yesterday. Although I'm extremely happy with the phone I have this teething problem.
Once I updated right away and kept the sim in I got the 3G signal as there is no 4G where I live. Now everything works OK except the data. Once I switch on the data it works for about 30 seconds and stops although the H sign is still there. I have tried manually entering the APN and the problem still persists. Network is not a problem because same sim in my old phone gives continuos data in 3G. Strangely 2G data works with no problems!
In the forum one plus one had same problems but no direct solutions. Is this a recurring problem? Should I return the phone or replace?

Hi, since I got this phone and I've been having problem with the data connection, wifi is working fine, but 3G is not, it shows the 3G symbol but keep switching to H symbol and back again to 3G constantly, i never been able to surf the web or do anything online on 3g connection since i got it.
I tried putting in the setting from my provider and got the samsung network app thingy but nothing helped, even after updating to NoDo.
This is really bothering me i cant enjoy the phone when im outdoors, i switched back to my iPhone 3gs temporarily.
I really hope this can be solved.
I'm thinking if there is some way to make the phone only works on 3G and turn the H off.

H is for HSDPA and is far more faster than 3G. I reckon you run ADC on startup using samsung tools and hopefully the problems with connection will be resolved. Alternatively contact your sim provider for network configurations.
Here it also switches between H and 3G, or well it did on my other wp7 phone my (european) omnia uses 3g+. That's normal; the H mode probably eats your battery alive, and it only switches to it when your data connection is active (i.e. data is being transferred)
Your problem appears to be an Access Point problem, you can configure one yourself at the mobile connection settings page. (bottom). Check the web for the settings you'll need.
You see most phones are configured automatically by their providers, but the omnia probably isn't supported.
Hope this helps
the APN for China Unicon is "3gnet"
just add it your 3g connection will work.
I'm having random 3G connection issues on my Samsung Focus.
At radndom times 3G connection is lost and the only way to get it working is to turn off and on the phone.
I tried putting the phone into airplane mode, turn off/on data, turn 3G off/on, nothing works, only a reboot works.
Today I checked my email on my phone and it says;
Last updated 4 hours ago
We're having a problem connection to exchange.xxx.com. Try again later.
Last tried 2 seconds ago
Error code: 80072FA8
This error shows up on all 3 emails I have setup.
IE doesn't work, Zune, any app requiring 3G connection.
And this happens at random times, at least once a day.
The phone has the lastest updates and is jailbroken.
One other thing to mention is, the phone is now having the 3G connection issue but i have it theathering to my computer and the internet connection is working while theathered, cause i'm posting this email.
I have no idea what's happening or how to fix it.
Thanks
same with me. are you using another carrier ???
Mine is unlocked AT&T Focus, when I'm using indosat (IM3) carrier, I'm having this issue. I downloaded Network Profile from Samsung Zone. After reboot the device, the network profile still pick AT&T, and I can't change it to my carrier.
Then I tried change my carrier to 3, after reboot the phone, the network profile changed to 3 INA. And after that I haven't got that issue till now.
Not sure what caused this. But when I looked at the registry there's a bunch of duplicated APN settings.
I had a similar issue, Focus AT&T on EU network.
Chevron unlocked and enabled the 3G toggle.
From time to time, I couldn't download from Marketplace or use the 3G connection. That was before I updated to NoDo. I haven't experienced this again since I updated.
To fix that, I used to toggle 3G off and on again after 15-30 seconds.
Sometimes, even that didn't work and I had to leave 3G off. Any lower data connection was working while 3G wasn't.
Speaking of data connection, not everyone is aware that after updating to NoDo, HSUPA is disabled on AT&T.
I'm having the same issue.
I´m using an unlocked at&t samsung focus at my local carrier.
I have this issue a few times a day, and the only way to restore my internet connection is rebooting.
I have noticed that this happens when my phone changes to Edge and goes back to 3G again. The issue doesn't seems to happen every time, but sometimes I lost connection.
Did you managed to solve this?
Same here
Using it with mtvmobile italy
Have to reboot everytime
I was having the same issue, being unable to connect to 3G. Just go the first page after Googling: set att apn. AT&T users should put in the APN, username and password. Hope it helps! It worked for me. =D
I´ve the same problem, here at Costa Rica with my focus which is not unlocked nor jailbroken

Did you solve this problem, I'm in Costa Rica but have issues with 3G connection... :-(
Hey,
so today I noticed my N4 couldn't get any telephone signal whatsoever. At first I thought the provider was just having issues but when I came home and tested my other phone it worked fine, so it's an issue with my N4.
Did a factory reset, problem remained. Then I tried activating 2G only and all of sudden the signal was back, telephone and data on 2G and everything works fine.
As soon as I uncheck 2G only however, both signals are gone and here's the kicker: even when wifi is activated and connected I get no signal. (with 2G+wifi I do however)
Had faux' kernel installed on stock deodexed, wen't back to stock kernel for now, didn't change anything else lately, problem just randomly appeared.
EDIT: nevermind, I just realized I checked 2G only on the other phone as well and forgot about it. Same problem there. Has to be a provider issue.
Hi All,
First time poster with an unusual problem. I live in Australia and have a Samsung Galaxy S5 SM-G900F which is the European model. Up and till recently I was getting Telstra 4G reception. Now all of a sudden I'm only getting constant 3G reception. I have confirmed that there are no 4G network repair/maintenance/upgrade issues in my area. It was only in the last week that I noticed the constant 3G reception so I can't really pinpoint a specific incident or exact date as to when it actually started happening. Here is what I have tried thus far:
Phone restarts, changing network settings and switching to flight mode.
I've confirmed that the phone network is set to LTE/WCDMA/GSM (auto connect).
I have done numerous hard resets, cache wipes, Dalvik cache wipes, drive wipes, etc.
I have rooted and unrooted the phone numerous times.
I have tried several different stock and custom ROMS.
I have tried 4G SIM cards from other phones.
Tried numerous network switching apps.
NOTHING WORKS!
I always love to tinker with my phone so I'm always looking for ways to improve the phone's performance. It may be that an app (battery improvement/tweaking type apps) I installed somehow changed the network settings but I would have thought a million hard resets would have sorted that all out but apparently not. At the moment I'm running a rooted stock Android 5.1 ROM. I've tried stock Android 4 and 6 as well with no joy.
Here is the unusual thing. When I put in another 4G SIM card into my phone the network still remains on 3G but as soon as I put my SIM card back in 4G magically reappears. It's bizarre. At least I know my phone can still get 4G. You would think that would solve the problem but it doesn't. When I am in an area where the 4G signal is weak the stronger 3G signal kicks in as it is supposed to. When I get back into an area with strong 4G reception the phone remains stuck on 3G and no matter what I do it won't go back to 4G unless I go through the convoluted process described above.
I am all out of ideas. I think I have tried everything possible. I've trawled the web and I appear to be the only person in the world with this problem. I don't know if it is a software or hardware problem with my phone. My SIM card works in other 4G phones so I don't think it is part of the problem. At the end of the day it's not a big deal as 3G is fine but I'm just one of these people that has to fix a problem. Worst case scenario I'll probably upgrade the phone in the next 6 months.
Any suggestions or tips other than what I have listed above would be greatly appreciated. Thanks in advance.

hi everybody,
My Xiaomi MI A1 32GB lost data connection several times a day. I have only a visual notification - X symbol within signal strength bar(not above like should be in this case). This symbol in general is regarding roaming connectivity, but i am at my home network. When i enter in Settings and deactivate/activate the SIM, the data starts again. All the time i dial and answer the calls, it is only related to data connection in my home network.
Any idea how to fix it in other way, may be to install network signal booster app?
This is an Android 8.0 bug, not a phone one, right?
Regards,
I've had the same issue when using two SIMs. To fix the issue temporarily, I switched to flight mode for a few seconds, then it worked for a while.
Now I've switched of the second SIM card and since then the issue never happened again. So if you don't need two SIMs, I'd suggest to turn one SIM off temporarily till the problem is fixed. Maybe it is already fixed in the February update.
