[Q] Overheating while roaming data on 3G - Galaxy S II Q&A, Help & Troubleshooting

Hey folks,
After a good year reading this wonderful website I believe I will need to ask for your help or advise.
I am in the possession of a British i9100p originally simlocked on O2, acquired in Nov 2012. In june 2013 I installed CM 10.x on it, and then replaced the battery with an origanal big size Samsung battery in Nov 2013. Today I installed Paranoid Android, latest nightly build on the phone.
Since about half a year I noticed that my phone always overheats while roaming data when abroad, irrespective of using my O2 sim or a pay-and-go sim of the visiting country. Back home I dont experience these overheating issues.
1st time : India with Network of Airtel + sim around Delhi
2nd time : Norway with all networks on my UK sim, Bergen
3rd time: Turkey Turkcell sim, Istanbul
The overheating with battery drain is only outside UK with 3g data, when I switch to 2G there are no problems and the phone is staying cool. Since I will be travelling more soon, I wonder what the problem causes and how to solve it without compromising the 3g connection...

Using xda2 abroad

Hi there... this is my first post so forgive me if i don't get the protocol correct!
Will my 02 locked phone work when roaming in europe because i have family in Germany and France and i will need to use my phone abroad?.
If it will roam OK i have no reason to unlock it.
Cheers
Yes, it will roam fine, but be aware that O2 charge a small fortune for GRPS usage abroad.
You should be able to get an add-on package for european roaming that will reduce your costs a bit, but it still works out very expensive. I have this addition yet I was recently charged £1.70 for a 4k download from France. Spain is even more expesive for some reason.

[Q] No receprion abroad

I've recently been in Morocco with my Streak, where I had no phone reception at all. I contacted my provider (O2 in the UK) who told me that I should be getting a network, my account is fine. However I had no network until the plane touced down back in the UK. This also happened to me last year when I spent time in the US. Could anyone be kind enough to suggest what settings may be incorrect on my Streak, which may be preventing me from picking up networks abroad? The phone is fine within Europe (UK/Germany/Switzerland) but doesn't work further afield. I'm traveling Stateside again in a few weeks I'd like to get on top of this problem before I go. Thanks.

Galaxy S2 and Virgin UK

Hi everyone
I'm new here and I have Galaxy S2 on Virgin UK network. I would like to ask S2 owners or anyone who can help me about advice. I spent hours in many forums and I still can't truly get what is wrong with my phone.
The problem occurs when my phone is working in automode (gsm/wcdma). When I get to place without proper 3G network coverage my galaxy s2 goes in to 2G and never comes back from it to 3G (in automode). When I want to come back to 3G I have to reboot my phone or toggle it manually to WCDMA only for a second and switch it back to automode. Whenever I do it I'll have 3G (or H) to the next time when I'll go to the place without 3G coverage.
Is there anyone who owning galaxy s2 on Virgin UK with working 2G - 3G switching in automode (gsm/wcdma). Anyone even in other UK networks or it's just normal behavior for galaxy s2? I know at least 2 people who have the same problem with S2 and Virgin.
I've tried many different roms and a lot of modems too (even orange UK, 3UK, T-mobile UK stock modems), Juice Defender beta, other software switchers and wigets.
Help, please
Not on virgin, but a UK user on 02. Never experienced the issues you are describing, so it seems network specific.
Thanks mate. I need all your opinions before I'll complain to the Virgin.
Possible its the masts you are picking up from .
SGS2 and 1 bothy worked fine on Virgin for me >> have you entered the correct settings from the web site .
CSC for Virgin i always used the CPW carphone warehouse one as some UK csc do not have Virgin settings .Virgin of course runs on the TMobile network .

That will of course have invalidated your warranty from Virgin .You need to restore if sending the phone back .

Of course. I came back to stock firmware 2.3.4 last night anyway.
Thanks I'm going to check CPW carphone warehouse. Settings are from Virgin website and I'm picking up signal in BT4 1QF area now.
EDIT:
Well
I flashed GT-I9100_CPW_I9100XWKF3_I9100XXKE7_I9100CPWKD1 - CPW carphone warehouse with factory restet before of course.
Phone started in 3G obediently. I switched from automode to gsm (what occurs when I'm in place without 3G) and I switch it back to automode again to check whether in goes in automode from 2G to 3G or not. It was last time when I saw 3G icon on the screen. No luck. Still doesn't work. Absolutly the same.
I've heard similar stories on other threads, It may be coincidence, but Virgin runs on the T-Mobile network, and they have just recently started sharing their 3G network with Orange.
There may be some hiccups in the switch over, that's affecting Virgin.
I could be totally wrong, but the dates coincide with the similar Data issues that I have seen discusssed on other threads.
I would call Customer service personally.
Regards and good luck.
I just finished my conversation with customer service. They said that It can happen in places where 3G signal is weak and 2G strong. If there is strong 3G signal switching should work. It should but it doesn't. Thats what I known now. But I'm afraid I knew it before already . They said I can try to replace sim card or mobile.

I've noticed this a bit with my galaxy S2 and its quite annoying, i used to get the T-Mobile network all the time which provided me with 3G quite often but for some reason the switch has left my phone connected to the orange mast with no 3G. I might ring up as well.

I upgraded another device with Orange last week, and they provided a new SIM card. I'm wondering if that's due to the switch.
Good luck.
Regards
I'll try to replace sim next week
Not seen this problem (for me) on my SGS2
SGS2-XXKL1-Hyperoid 5.2.21/Siyah-2.6.7 - Virgin UK.
Although my Virgin Blackberry has the very same problem? time for a customer service call...
Well I sorted out my problem pernamently and I now what is going on. This is network problem. Go to your network settings and change your network from Virgin to virgin I spent 1,5 hour speaking to Virgin support and they couldn't help me. The didn't know. They told me that virgin with small v it's orange in fact but we can use this network that's why it is also named virgin.
Regards
Check your connectivity with calls. My wife is with Virgin but can't get signal at work or home. Their signal on data is only the second usage of T-mobile which is not the best.
Sent from my GT-I9100 using XDA App
Looks like this new EE network is now T-Mobile and Orange. What are Virgin using to do their data?

Problem to connect to 3G

hi everybody,
i have a UK T-Mobile Motorola Atrix that i received as a gift (MB860; 45.31.2.MB860.T-Mobile.en.GB; android 2.3.4). I live in Morocco where there is no T-mobile. I try to set the phone up to get 3G connection but it never works. it keeps trying to synchronize and changing the signal from normal to 3G to H and so on.
i tried my simcard in other phones and it works and I tried other simcards with 3G in my phone but still the same problem. i called my network technical service and they told me to upgrade the OS. i did it since there was an update available in the t-mobile web to the version mentioned earlier yet the problem persists.
when i see other phones with android there is a option to activate the 3g that i don't have in mine, i think because it's a t-mobile version.
can anyone here give me a hand with this?
thanks in advance.

Question regarding change of firmware to UK.

Dear friends,
I recently bought an S9 Plus dual sim, SM-965F in my home country(Pakistan). Then I moved to U.K and bought Three 3 mobile sim. The sim works fine but there are issues with it.
First, Network signals are always low. I hardly get 1 to 2 bars. Only in center of towns it's 3 bars but still not full signal.
Second, when I install U.K based applications e.g, Three mobile app or Just eat, it keeps telling me that facility is not available in your county. Every app still thinks it's in Pakistan. I tried to change in Playstore, Accounts but not able to change country.
Third, the battery is draining like hell. Within 6 hrs I am dead from 100%. It bever happened like this in Pakistan but happening in U.K. I feel there is incompatibility issue.
Can anyone guide me, what should I do? I am thinking of flashing European firmware. Does anyone know compatible EU firmware which I can flash on this phone? Its unlocked and Dual Sim.
I have attached picture of my phones software info.
Please guide me further. Thank you
