Samsung GT-P3100 only works with radio 1800MHS

Hi all,
I have Samsung tab GT-P3100 7 inches.
It works great with 1800mhz supported sim card. When I put 900mhz sim card in it. It shows "No sim card"
I have been faced this problem P1000 tab too.
Kindly someone guide that either it is hardware issue or some functions of radio not working.
thanks and regards

I rooted may be try a different rom as cm10 from www.teamhacksung.org
Try to play with connection setting in setting and try to be like your other (solved tab)
See manual if it supports 900 range
Tray to switch airplane mode off then off then wait
Try to switch between 3g and 2g networks from setting then reboot
Try to enable mobile data from setting and reboot

[Completed] Cyanogenmod 12 for HTC Daul Sim (Network issue)

Hello
I recently flashed CM12 nightly offical rom
I am liking it very much but i m have trouble with the network settings
Dual Sim
Sim 1 - 3G Data Only
Sim 2 - Calls only
Now when i set LTE network mode on sim 1 and do the *#*#4636#*#* i get the H+ working but the sim 2 setting switches to 2G which causes calls to loose all incoming/Outgoing audio...
and when i set LTE on sim 2 calls work fine but then sim 1 switches to 2G causing low speed untill i manually change that back...
I have searched lots of thread but found no working fix for it for my HTC 816 daul sim
Kindly guide me to the thread where i can get my problem fixed permanently..
Thanks

Hello, thank you for using XDA Assist.
Post this as a bugreport in the XDA Thread of the ROM you're using. Make sure you're on a clean flash though. The experts there should be able to assist you.
Good luck!
