Hi,
I had verified the same test network setup with same authentication parameters with the two different UE’s and we had a succesful UE attach with both the phones.
How ever, we dont see the sierra wireless modem trying to register to the test network when we put back the same sim card in the sierra wireless modem. eventually NO UE Attach.
We are blocked on making progress to have an UE Attach with our test network. providing status of all the AT commands below

How to force the UE to register the test network and also how to disable/enable airplane modes
I tried with at+Cfun=4 and at+cfun=1 . But no luck , I dont see any wireshark traces indicating that UE trying to communicate with the EPC.
Please provide us your inputs.
