About the Quectel EC25-AU

Cat 4 · Australia, New Zealand, Latin America · Quectel12

The maker notes that B2 on the EC25-AU has no receive diversity, so performance drops in weak signal. No B20, B12 or B13: not for Europe or the United States.

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.
