Why my sim card not working as data network
i have a tray for dual sim cards but there is one of sim card not working in my phone for data network but its working in other phones even i put another sim in my phone in same tray and it is work very fine then i went to the branch to replace the sim card but it also do the same issue no data network in my phone but working very well in another phones so why the data network in this sim card exactly not working
I call customer service technical support to resolve the problem but no problem in sim card because i try it in another phone
