I am struggling with some basic stuff that I can’t resolve.
My connection has been lost, when i try and reestablish it
i get "registration is denied and then pdp deact. In order to
isolate the problem, I purchased the AT command tester,
it produced the following results when i tested.
Thank you for helping.
