To summarize, after doing the AN command, it is necessary to reset the network right away using ATNR. Also, I see that you’ve got a space before the APN. I don’t think that will work.
Additional notes, you are trying to use a provider other than Verizon US. The module is only Certified on Verizon in the United States. Support for other countries or providers has not been added to the modules firmware. Nor has it been certified to function on any other networks yet.
