recently i just got the grand 2 like 2 months ago...when i tried to activate mobile data (of sim1) i had a problem ,it's not working,
I tried to trouble shoot the problem by changed apn's and stuff like that with the cust service,,nothing,
however,when i remove the 2nd sim the data of the sim1 ( which i want to activate) starts working ,I always make sure that sim1 os on wcdma and sim 2 mode is on gsm...i had sim 2 as clipped micro sim,however went to store and got a brand new micro sim to see if the clipped one was the problem ,nothing changed ,also swapped their position and placed sim1 in place of sim 2 and voice versa ,nothing happened same problem ,,,I also sometimes get a message saying:
the mobile network will be unavailable until you restart with a valid sim card inserted ,,and only the restart button available and u can't override it by pressing home key or anything so restarting in this case would be mandatory ,,that's why i chaned the 2nd sim card but nothing happened.
now i still can't get mobile data on my neww phone from sim1 and it's driving me crazy ,i think it's a software issue but am not sure cuz when i go to sim card manager and change the data service network to sim2 then put it back on sim1 ,some times the H+ appears and it works ,but not always and not for a long time,,,,,so the problem is between mobile data and dual sim functionality ,do u have this as a common issue ???,,please help
again ts steps i made:
1-re positioned sims in place of each other.
2-changed sim2 into an original micro sim instead of the clipped one i used to have.
3-i reset phone to factory defaults but same problem appeared
