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 legal ban; it depends on the operators: Permanent roaming is legally permissible (Cullen International: as in most of the Americas); whether it lasts depends on agreements between operators.4
