Network access: long-term roaming
Many globally deployed IoT devices use multi-network roaming SIMs that can attach to several networks in a country, but some countries restrict long-term roaming by foreign SIMs. A local SIM roaming domestically is not affected.
No clear rule found: We have not found a clear rule on long-term roaming for IoT devices here yet; confirm with the operator or your connectivity provider before deploying.
