A wireless communication device operates between a WiFi link and an LTE link. The device receives a request indicating a user identifier and determines if the user identifier has sufficient usage credit. If there is sufficient usage credit, the device exchanges WiFi signals and LTE signals including user communications. The device decrements the usage credit and transfers usage credit consumption over the LTE link. After decrementing the usage credit, the device determines if the user identifier has sufficient usage credit, and if the user identifier does not, the device transfers a credit request and receives an additional usage credit for the user identifier over the LTE link. The device exchanges additional WiFI signals and LTE signals including additional user communications. The device decrements the additional usage credit and transfers additional usage credit consumption over the LTE link.
