Hello,
we are trying to register a new neo aeris sim card using a SIM7500A module with AT commands.
We followed the "Get started" tutorial but keep getting network registration denial.
The test sim card has been provisioned in the neo portal.

Please review commands below and let us know your suggestions.

Thank you.
