RSim 10 - US Sprint - SMS & Cellular Issue
 

Hello Everyone, This is my first post i am making here.
Its first time i am using a RSim Phone, Have little bit of knowledge as few of my friends already had it.

my phone was running on ios 6, yesterday i received my rsim 10.
phone is no unlocked properly with the rsim, call feature is working where as sms and cellular data is not working (phone is also not activated as the SMS is not working.)

Some time the network turns to no service and some time it shows up the name, but any time the call feature is the only thing that works.


please suggest what should i do ? any patch or downgrade ios ?

Update :-
Just now realised, There is no 3G or 2G Icon but the net is working.
the only problem is with messages.

and most of time instead of showing carrier name at top, its showing no service.
