MTS is really a big hectic one to be experienced. even the bill date is far they use to call us like a hell out time and ask us to pay even the service is really worst and weak I have seen till now . they give some times best offers but do the network problem so I filed a complain but bill till date there do not care for it and no replay from them it is west of money if u use this worst network operator .
Offcourse every operator network is not soo good but compared to others this is the bad network they will give unlimited offers but we can not use them at all some times the net speed will be as low as 120kbps . it suggest the costumer service is also the worst .
