I’m currently trying to get my R410M to work. I’m in Germany and I have a Vodafone and a 1nce (Telekom) SIM, both of which work with my SARA-N211.
Here’s what I’m trying to do (With the 1nce-SIM, but it’s the same with Vodafone):
at+ubandmask=1,128 (both networks use band 8 for NB-IoT) at+urat? +URAT: 8 at+cgdcont? +CGDCONT: 1,"IP","iot.1nce.net","0.0.0.0",0,0,0,0 at+cops=? +cops: (1,"262 01","262 01","26201",9),,(0,1,2,3,4),(0,1,2) at+csq +CSQ: 8,99 at+creg=2 at+cereg=2 at+creg? +CREG: 2,2 at+cereg? +CEREG: 2,2
That status doesn’t change and it doesn’t matter if I only use creg or cereg or both.
Sometimes it doesn’t respond at all, but when it does, it takes a couple minutes and the response is:
+CME ERROR: no network service
I also tried that with different combinations of CREG and CEREG, but that doesn’t matter either.
at+cgatt=1 +CME ERROR: no network service at+cgatt? +CGATT: 0
I’m currently all out of ideas. It would be amazing if someone could help me.
As far as I know, both networks need AUTOCONNECT to be set to FALSE and CR_0354_0338_SCRAMBLING set to TRUE and the R410M has both set to TRUE by default, but I couldn’t find any way to change these settings.
