I am not near my test network. I will go there thursday and perform the AT COPS cmd again.
It is a band 3 network which I know my modem supports. Its PLMN is 00101. I will double check these Thursday however. The sim I have in now is not my private SIM btw. I can show you those results instead later on Thursday.
I +copn and see that my PLMN (00101) is in the list. Worried cops won’t return my network on Thursday…
