We would like to use M2X data service, we would like to check if AVNET Global LTE IoT Starter Kit can access M2X service from oversea (i.e. Hong Kong or China)? If not, Any development can support the application? Will AT&T SIM card support roaming or we should have location mobile network operator's SIM card for internet access?
