We are attempting to connect to Cell Service using a Hologram chip, but keep getting errors at the following command:

Serial.println("Try AT+CPSI?\n");

It seems the SIM is behaving oddly, before even touching our APN, any help?

Correction, line of code is: success = netSendCommand("AT+CPSI?\r",1000,"Online");

Issue solved. SIM card was inserted improperly.
