About the Quectel EC25-AU
Cat 4 · Australia, New Zealand, Latin America · Quectel12
- 4G B1 B2 B3 B4 B5 B7 B8 B28 B40
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.
