BG77xA-GL restrict to certain networks?

Is it possible to restrict this module to only use certain networks we have tested meet our requirements.

I’m aware I can choose a single network with AT+COPS=1…

But is there a way to use AT+COPS=0 so it is auto but don’t try and connect to certain networks?

For example we have found that PSM mode does not work with some networks but it is fine with others. So ideally we want to supply a list of networks we have tested.

Hi @Tom22

How about fix Band? have you tried? I think different operator has different bands.

Unfortunately both good and bad networks use the same bands.

eg
Vodafone NB-IoT B20 works ok.
O2 LTE-M B20 works ok
Vodafone LTE-M B20 does not work with PSM,

Hi @Tom22

So, you need to check with VDF if support PSM.
