3G connection on 10.1

Hi..
I just bought a tab 10.1
Somehow the 3G connection is not stable.. it will suddenly be turned off even though mobile data is on..
I checked the apn settings and it is blank.. typed in my own and after awhile it disappears too..
Is this a known issue?
Anyone facing similar issues?
Sent from my Energized HTC Sensation
For some reason my 3G data is not pulling through the tablet either. This is from my Galaxy Prevail
Are we the only two with this issue..
Wonder what is the cause:
Sim card?
Hardware?
Software?
At a lost now..
I have a similar problem. On my unit the H+ is displayed only when there is network activity and when there is no activity it turns to 3G. Problem is that this causes about a second of lag on every click on the link before it turns to H+ and then starts to download the page.
Another problem is that the signal strength display in ASU is suck at 4.

Peculiar data problem [India mobile networks]

Hi i have a peculiar data connection problem with my galaxy s3...
2g/3g connections work fine, and when the mobile loses signal and gets signal again after sometime, data connection doesnt start again automatically (eventhough mobile data is enabled in settings}..
only turning airplane mode on & off restarts the data connection...
this doesnot happen everytime the mobile loses signal, but maybe like one in three times...
i have tried airtel, vodafone and relaince simcards, it's the same...
and i've been flshing different ics and jellybean roms and radios.. the problem remains...
anyone experienced this?? any solutions??
thanks

[Q] Phone looses data connection when on a call

I'm having this issue almost all the time.
After some minutes on a call (after 5 or more minutes) the phone looses data connection (either HSPDA or 3G or GSM).
As soon as I hung up the data connection restores again.
It doesn't matter if using Bluetooth or speaker.
Mostly it happens while I am driving and I have GPS turned on as well...
It did this since day 1. Have tested ALL modems so far and all ROMs (custom or stock). Nothing would fix it.
It's not that it switched from 3G to 2G, it is just loosing any kind of data connection/connectivity.
Is this an operator issue? Vodafone Romania
Any idea?
Thanks.
Hi
The same "problem" here Every time I have a call, the data connection is lost. As soon as I hang up, the data connectin restores again.
I had this issue also with other phones. Maybe it is a operator issue. To safe bandwide??
It doesn't matter if I have 2G/3G/GPS/WiFi on.

No problem with GPS i can use navigation in my car
No problem when i use wifi to connect internet
The problem occurs only when i use mobile network internet... Very annoying
