Sierrawireless 3G, Edge & GPRS card = R 1 900 on MyChoice75. Sierrawireless Edge, GPRS card = R 0 on Mychoice75 or Novatell 3G = R 0 on MyChoice75. I am in a 3G area. Advice as to the best option? I think that the 3G, Edge & GPRS option is too expensive and I do not like Novatell - leaves the SW Edge card. Will 3G towers also be Edge enabled?
