Although the EC20 can switch carrier profiles with <code>AT+QMBNCFG</code>, the selection built into the module is quite limited. My EC20 R06, for example, came with only four profiles: ROW, China Unicom, China Telecom, and China Mobile. Another EG25-like module had twenty profiles, but still lacked VoLTE profiles for some Hong Kong carriers.</p>
