Before the arrival of Telenor, Mobilink was the best as far as network & packages are concerned,
But now telenor is the best, because of its network(covers almost all network locations as of mobilink, Best in northern areas specially at hights;where all other networks fails)
Call packages are better then mobilink, but both mobilink & telenor are more or less the same as compared to other natworks..!<<
Ufone(Sarkari line; quality is also sarkari),Warid (some better in postpaid) & Zong are low quality operators, Any person using cellular services more than 10yrs will not prefer or trust all 3 of them, Need time to rise in the market
