Many USB modems have been certified to work with the CBA850. For a list of supported modems, see CBA850 3G/4G/LTE Wireless WAN Bridge Release Notes  .

Card Activation

Before cards can be used, they need to be programmed with the subscriber information required to access the service provider’s network. This is normally referred to as the card activation process. When a service is purchased, the carrier will request the card’s ESN number, normally found printed on the wireless card. This number is then used for card identification by the different activation protocols.

Cards directly purchased from the wireless carrier can ship preactivated or sometimes with companion software that is used to perform the initial activation. In either case, cards that are already activated do not need to be reactivated.
