galaxy tab gsm problem

I have a galaxy tab t-mobile bought from USA. Whenever I install my simcard it does not register to network. I tried with other phones and there is nothing wrong with GSM network.
I installed p1000XWJMI rom but still the same problem.
Please help
Had a similar experience with my SGT. SIM card was corrupted. New SIM from retail store fixed the issue.

If it is an older SIM card some weird problems can occur... just go to the shop and get a new one.
Maybe you can test it in a Galaxy S (similar hardware)... if the problem persists there, it is highly likely the SIM causing the trouble
I had the same problem on the Milestone... after replacing the SIM it worked fine again.
Try this . If you have data block on yoour sim card like i do . You need to go into wireless and network to mobile network to network mode then pick GSM only . then reboot . It work for me on at&t
I changed the sim cards and choos gsm only option from settings
no change so far...
I assume the Tab is not SIM locked?

I dialled *#7465625# and all locks seem off.

For many posts members have pointed to the sim card not being compatible with your tab. What are you doing?

* restore your efs backup
* It's very weird that you can not install other firmware. Remember that you can not do MG9 downgrade modem. Try install Kitkat with pitfile.
I used to root my Samsung S3 phone with different types of custom roms but most of them drained out my S3 bsttery fast. Due to this experience, I'm scared to root my Samsung S4 which is still in it's original rom and already updated to 4.4.2. When I looked at your screen shots, I kept wondering why your android OS was so high. I was thinking perhaps it was due to your phone being rooted? Is it because most custom roms drain battery faster than original roms? My S4's battery lasts much longer than my S3. I can put aside my phone with the wifi on and battery at 100% when I sleep. When I wake up, the battery is around 98%.
i have same problem anyone can help me plz
thanks in advance
any idea please

Hi mate,
The problem in the case above is that the phone lost its IMEI , if your case is the same and you do not have a efs backup , you will have to go to a service shop to have it fix , they need a tool like z3x or similar to fix it

thank u,
my IMEI is fine its repaired IMEI "cause here in turkey somehow we have to do that" but as written above i get no network after return it to 4.2.2
any idea?
thanks in advance

Does the phone show the correct imei? Possibly blacklisted by carrier?

SM-G950FD no network available

Hi everyone, i'll beging in thanks for anyone that can help me with my problem
So my phone just got a random crash, after that the network won't work at all. What i tried :
Testing another sim card from other provider
Wiping the phone in Odin
Custom rom with custom kernel
Restoring EFS
Checking if water damage inside the phone
Imei is good
Phone was bought in Canada it's the dual sim model so no warranty here.
Could i get it repaired in the country of origin for free ?
Also can a *box* could repair the modem ?
Any help would be accepted
Thanks
