We are facing problems with Xbee 3G cellular modem in South Africa.
No problems in Europe, Mexico, Colombia, India with many different internet SIM operators.
SIM is from Vodacom. APN settings are same as european ones but they are stating a dialing number *99#; on mobile phones it looks not to be necessar but Xbee 3G does not connect.
Is anyone succesfully working with XBee 3G cellular in South Africa?
Any suggestion is welcome.
