I just purchased a MKR GSM 1400 in a kit with the antenna and Arduino SIM card directly from the Arduino Store. I am going through the online setup process and everything went fine until it tried to connect to the cellular network. I got the error shown in the attached screenshot.
I inserted the SIM card, activated it, and used the login credential provided in the activation confirmation email.
Also, I connected both the USB so the test sketch can upload AND I connected a 5V 2A power source to the VIN terminal to provide enough power for the radio during transmission. I monitored the VIN voltage with a multimeter and normally it is 5.01V but for a brief period during the GSM connection test it went down to 4.98V. I'm not sure if that's enough to cause a failed test?

Any trouble shooting tips?
Thanks!!
