I turned my phone off before boarding a plane, and then when i turned it back on it had lost all the data connection info. Now it doesnt see the phone network either. I am using an unlocked phone on t-mobile in the US...It has worked fine for the last 6 months....
I tried re-entering the data connection info, but i still down get either a connection to tmobile gsm or edge or gprs. When i go to manually select networks, it only sees att, which of course i cant connect to, cause of my sim card being tmobile.
Any thoughts ?
TIA

Is it possible that the phobe can lose the unlock ? Would only seeing ATT be the a symptom if this were the case ?

Hi, I just got the 8.9 3g Tab (P7300).
when I insert the Sim card to the device, it still shows "Please insert sim card"
and when I go to Setting, Network service. It tells me "Insert sim card to access network service".
I tested my Sim card to my Phone, it is ok. and i don't think there is anything wrong in the position of sim card when I placed to my 8.9 tab (metal surface face down)
I also did some research on the possibility of lost/corrupt data in EFS folder.
However, I saw my IMEI and Serial no is showing correctly (Not "unknown" or the default one). and I tried to odin the stocks 3.2 rom, wipe eveything. And i also tried to recover the nv_data files and do the chmod radio radio to that files under EFS. it still doesn't work.
does anyone here have some advise for me?
Thanks so much.
sounds silly but did you insert it far enough?
you really have to push down hard until you hear a little "click" the card then should stay in position.
did you install a p5 (3g) rom and not a p5wifi only?
Yes. the rom i flash is P5 3g room and for P7300 not P7310...
and I do hear the sound and the Sim card totally locked inside.
and I need to Push it to eject it out.
So i have no idea why it doesn't work.
is your phone 4g? if you insert a 4g sim into a 3g device it wont work. this probably isnt the case, but who knows....maybe they messed up your data plan and gave you a 4g sim for your 3g device.
did you get your tab from a carrier? did you buy it used and the guy before you had it from a carrier? if so maybe its sim locked?!
just guessing here though :S
How can I know whether my device has sim lock or not?
And how can I get it unlocked if so?
As my device is given by my fd so I don't know whether it is locked or not.
But I am sure it is 3g device instead of lte and my similar card is also 3g
On T-Mobile, are there network restrictions that prevent me from using my the data connection from my phone's micro SIM in my galaxy tab? I put it in and the browser will only go to the "My T-Mobile" page. Do they frown upon swapping SIM cards like they do tethering these days?
Hi all
I'm new on WP
I had changed my SIM card but I can't connect to SIM data connection
I could connect to internet before, both SIM and WiFi, but now no internet access
I had reseted my phone and it's worse now
Now I can't connect with WiFi or SIM data
I asked my carrier, No problem on SIM card
What should I do?
------------------------------
WiFi problem solved but still can't connect to SIM data
You may need to do a hard reset on the phone, if you can't connect to WiFi even. That shouldn't have anything to do with the SIM.
If it was *just* the cellular data, I'd say it's probably an issue with the APN. But WiFi can be used without a cellular connection at all; it should never *not* work.
I have a moto X 1st gen here in India. Its unlocked,not rooted. One fine day it thrower me an error "your sim card does not allow a connection to a network". And I am without network in my mobile.
My IMEI is same as in the battery
Device is not rooted
Sim card works fine in other mobiles
Tried different sim cards but still same problem
Didn't fiddled with any network settings.
After reading through XDA threads I did
Cleared data/cache
Restored the stock firmware again.
Did that network menu reset to switch radio on and off many times
Not able to get any network signal at all. Is there anything I am missing?
