mere pass bhe yahi masla raha tha. Mene ak dost se rabta kya. usne jo hal mujay btaya wo men apko bta deta hn. jitne bhe androind han wo is waq tareban 4g supported hain. asal masla apke sim ha hoga. agar wo purani sim ha mtlb kafi old 2012 2013 ya 2015 ki nikli howe. to is me 3g speed he aye ge ku k apki sim support nhe ha 4g se. iske hal k lea apko yah sim band krwa kr franchsise se new nikalne hoge. Nano is best for that. qk nano cureently sb se fast internet dete ha.

i hope yah apke help kre ga.
