PDP Authentication Failure

Hi! I’m having trouble connecting my uBlox c027 with LISA U200 cellular modem. It fails the join step with a PDP Authentication Failure. I’ll include the debug output below with the AT output for the failing step:

Your modem APN/password/username may be wrong

Hi,

Thanks for reaching out! Can you try again now? We took a look at your SIM and saw that it wasn’t activated yet with the carrier. It’s now been activated fully with the carrier and should allow you to connect. Let us know if you have any further issues and we can take a look.

Thanks,
Ryan

Ryan,
