Has anyone had any success connecting the GL7500 to a Verizon network. I immediately get a registration denied (+CREG: 3) when I power up the modem. I’ve been in touch with Verizon support who told me it may be a modem problem. They could see the modem’s sim but could not offer an explanation why is was getting denied.
I’ve tried two separate GL7500 (both with Verizon fw) and two sims with multiple account configurations. I’m using a Taoglas MA750 antenna.
Hi,
Have you resolved the issue? First please install the right FW to your modem, it should be firmware with VZW name: https://source.sierrawireless.com/resources/airprime/software/hl7588-firmware/#sthash.kQH6Bdor.dpbs
Then try to configure PDP context 3 by: AT+CGDCONT=3,“IP”,“vzwinternet” and reset the modem.
