BG95-M2 - EPS network SMS problem

IoT Modules LPWA Module
1

Hi,

We are trying to send SMS using the BG95-M2 module, but it does not work.
With the same SIM-card, we can send SMS using exact same commands and an BG96 module.

EPS network is registrered.
CEREG
+CEREG: 0,1

But CREG is not.
+CREG: 0,3

How do we send an sms with EPS network ?

Best regards
Jakob

Hi jju

Since BG95-M2 support CATM1&NB2 network only ， But BG96 support CATM& NB1&EGPRS&EDGE mode ， so you are on 2G environment .

If you have to use B95 ,pls Using Bg95-M3 , it support EGRRS, and could send sms via 2G network .

Thank you for your reply.

If we look in the quicksheet for the BG95-M2, it seems that it should support SMS, but am I reading the quicksheet wrong ?

Hi

  1. Pls send AT+QIACT? to check PDP status.

  2. Pls lock your BG96 in catm or NB mode， send sms again ，If BG96 can send a message successfully, it means that it is not the problem of SIM card provision.

Hi,

  1. AT+QIACT?
    OK

  2. How do I lock it to only one mode ?

Thank you.
