I am trying to connect LE910-SV1 (embedded in our product) to verizon network. My question is when I query for CREG, I always got 3 (registration denied) back. However, when I query for CGREG, I got 1 (registered) back. Now, if I ignore CREG and tried to setup a PPP session anyway. I was able to setup the data call successfully with CID=3. I can do a ping on the network so it seems everything is working.
Is this sounds normal from your expert opinion? If not, what is the potential problem here?
Forget about this, it seems like I need to check CEREG instead of CREG base on the “Telit LE9x0 Registration Flowchart”.
