Manually selecting an operator fails

[mathieucarbou]

Both with CAT-M and NB-IOT, if I select an operator, for example like that:

> AT+COPS=?
+COPS: (1,"F SFR","SFR","20810",9),(2,"F-Bouygues Telecom","BYTEL","20820",7),,(0,1,2,3,4),(0,1,2)

> AT+COPS=1,2,20810
ERROR
> AT+COPS=1,0,"F SFR",7
ERROR

It always fails with ERROR.

Only AT+COPS=0 works.

The problem is that I would like to select the operator because I need to exclude one (which is blocking my IoT provider).

Please let me know how I can select the operator.

Looks like a format error, try

AT+COPS=1,2,"20810"

Looks like a format error, try

AT+COPS=1,2,"20810"

No it does not help... Here is the full command list:

> AT
OK

# Preferred mode

> AT+CNMP=?
+CNMP: ((2-Automatic),(13-GSM Only),(38-LTE Only),(51-GSM And LTE Only))
> AT+CNMP=2

# Preferred IoT mode

> AT+CMNB=?
+CMNB: ((1-Cat-M),(2-NB-IoT),(3-Cat-M And NB-IoT))
> AT+CMNB=3

$ Set bands for France

> AT+CBANDCFG=?
+CBANDCFG: (CAT-M,NB-IOT),(1,2,3,4,5,8,12,13,14,18,19,20,25,26,27,28,66,71,85)

# Operator selection: try to manually set SFR

Same for AT+COPS=1,2,"20820".

If an operator, let's say SFR or Bouygues here, is blocking my M2M / IoT SIM provider, could this create the error ?

Ok! it worked! With: AT+COPS=1,2,"20810",7

With Onomondo in France:
