Looking more closely at that result, I see that it's got the MCC/MNC
info there as well as the name.

But looking at the first argument within the three sets of brackets
which show a detected network, they show stat information.

stat values a

1 - available
2 - current
3 - forbidden

So you're camped on MCC 219 and MNC 02 as I suspected from the "TELE2"
before I noticed them there.

AT+CREG?
+CREG: 2,1,"006F","1C90"


And the second argument ("1") in that result shows that you're on the
SIM's home network. If that was a "5", the device would be roaming

The SIM is also permitted to roam onto network ID 21901, but not onto
21910.
