[Q] Problem concerning Dual Sim phones with Data plan
Hi all ,
I am having a problem that is annoying me for a long time now , some friends have fixed this problem in their phones but don't know how , my last hope is XDA ...
I have a mob with dual sims , SIM1 is my default SIM where i do all my calls from and does not have data plan on it , SIM2 has a data plan , the problem that when I activate data plan in SIM2 , anyone calls me on SIM1 gives him that phone ( SIM1 ) is out of coverage area !!!!!! plus that the data plan on SIM2 is extremely slow and takes forever to load a page with connection error at the end .
my phone is Hisense U5 , i know it is not common phone , so I am buying Samsung Grand in very few hours and knew that it has same problem but it can be easily fixed , I dont know how to do that and indeed need a help before buying it .
waiting a reply plse .
