[Q] 3G stop working..

HI
I have a strange problem with my Arc s (the problem suddenly started this week).
when i turn it on the 3G works but after 2 minutes it show the H sign of 3G but no internet and also no calls. when i disable data i can call.
so i figure the 3G is working bad.. and cause to network in the device to fail..
its not rom problem.. i tried 5 different roms and the same (and the device worked great with he first rom before).
the store don't want to fix it because it say because i installed rom the warranty is expired..
can someone please guide me how to fix it ? can i order the 3g component and fix it? thank you

If you are facing the same problem in both ICS and JB then its most probably a problem associated with your SIM Card or Network Provider. Have you tried using the sim in any other device? If it doesn't work there too then you should contact your Network Providers Customer Care, only they can help you with that. If that doesn't work either then try flashing a different baseband, if that doesn't work either then you should think of getting both your device and sim card repaired/replaced.
Today I called my carrier and i complained again about my 3g and they said everything was ok, so I was already going to the mall to buy another chip,when I was leaving the house, to my surprise (and delight), my 3g miraculously work again without me having done anything, good that everything was resolved and thank Sumedha Kapoor :laugh: for giving me tips to solve my problem.

[Q] 3g data auto-disconnecting after some idle time!!

Hello guys!!
I am from India and I have flashed the latest Mokee-ROM in my 1S ..I have noticed a strange issue,
I have a 3g sim(Aircel) in the first slot and a 2g(airtel) in the second one.. The thing is ,whenever I enable 3g data,it works fine for the first 20 min or so..
Then the data connection simply disconnects and refuses to reconnect..
The toggle switch works fine,but I don't get the H+ symbol, here will be only a H symbol remaining... Then after restarting the device, the H+ symbol returns and I can use 3g again till the same thing repeats..
I have noticed that this happens when the device is idle,i.e when I'm not using the internet connection.
Need you help very urgently guys.. I dont't have any ohter internet connection..
Thanks in advance..

2G doesn't work, 3G is fine

Hello.
I rooted stock ROM (B520) on my huawei p6. Everything was ok for few months but suddenly i lose 2G signal (3G worked perfectly).
I installed B709 custom ROM by OXALIS v08 and I have the same 2G problem (3G works perfectly).
It's very really annoying situation because when I'm out of my town, then I don't have signal.
I can't be all the time on 3G, because 3G doesn't work out of my city.
I'm wondering of posibilities to solve the problem. I even tried to put SIM card of another operator and there is the same result (3G - fine, 2G - off).
Any idea?
