I recently activated a new SIM and it shows as “active” on my dashboard. It has a plan and I have a positive balance. However, my hardware will not connect with it. If I remove the new SIM and insert an older SIM (also active and positive balance) the hardware works perfectly. No change in hardware or code - literally the only change is to remove new SIM and insert old SIM and it works. Putting new SIM back in makes board fail to connect.
The SIM plans are different:
Old SIM: Pilot Plan
New SIM: Professional Plan Flexible Data
Would this matter?
I believe the hardware is irrelevant here, but it is a Botletics SIM7000G and Arduino Uno.
What can I do to troubleshoot this?
