3G services of any service provider are not reliable to date. waste of money,
CHAR-JI cloud from PTCL is more reliable can be carried discreetly & speed is so far very reliable lowest is 10MBPs . a Hop between UTHAL Lasbella ( Balochistan ) & back to Karachi superb connectivity over skype over handheld device(s) while there was no signals for UFONE & WARID after KESC station in Bela where as Mobilink die as soon as we cross the HUB Phone exchange.
PTCL Char ji is tested upto EDHI HOME on Super Highway thats the place almost all GSM networks go BLIND for next 3 kms.
if need is not work related avoid 3G / 4G till next year 2015
