Global SIM with roaming on

FortiExtender (Standalone) must always run on the modem firmware compatible with the native wireless operator’s SIM. Most of the providers in the world can work with the "generic" modem firmware included with the FortiExtender (standalone) image. However, this does not apply to roaming operators because roaming agreements require that roaming service providers consider all data service requests. For this reason, there is no need to adjust the configuration for roaming.
