Best mobile network coverage: econet
Best Mobile service in general: telecel
Best Internet Service - Liquid Fibre - (if you can get it)
Best wireless internet service Umax (again if you are in range of there towers)
Best ISP Coverage for internet - this looks tied between zol/liquid and yoafrica and definitely moving in liquids favour
PS: The above I took from a question that was asked sometime ago "Which one is the best network in Zimbabwe?"
