I just bought a glo modem. A sim card waz included in the modem{unregistered}. . . . .so i decided to try my other registered glo sim on the modem after installation, buh it doesn't connect. The folo-come sim was registered and activated the nxt day and i slotted it into the modem, stil won't connect. What cud be wrong guys. Do I av to recharge/subscribe to activate my modem or what.
