LARA-R211 2G register problem due to APN settings

0 votes
Hi everybody

I'm facing a problem with the LARA-R211. We do use it in the UK together with vodafone SIM cards. And as the support suggested me, I do receive the valid APN settings directly from the LTE cell when LTE is available.

Now the module is in an area where only 2G is available and I always get the "cme error 133 requested service option not subscribed". I can't figure out the problem and I hope, someone can help me. I do use the following commands:

AT+UPSD=0,1,"internet"
AT+UAUTHREQ=1,3,"web","web"
AT+UPSD=0,100,1
AT+CGACT=1,1
AT+UPSDA=0,3

Does somebody have an idea, how i can solve the problem with the APN settings? I think the issue is related to the username and password.

Thank you

mh

More likely you plan doesn't support data roaming, or the tower isn't supporting data in a manner usable to you.

Check what AT+CREG? reports

Your network provider should be able to furnish an APN, username and password for the private network if you have one, or access to such.

Thanks for the fast reply. Those are the values received by the LARA-R211 (from our log-file)

GSM State 1 [lac=0x010D,ci=0x000033D2,act=0],1543806284,0x30125301

State 1: registered, home network and act=0: GSM

I can also send and receive SMS. Only the connection to de vodafone network is not possible.

Any other idea?

EDIT: I forgot to mention, that the same simcard is working properly with the LISA-U2 module by setting the APN settings with:

AT+UPSD=0,1,"internet"
AT+UPSD=0,2,"web"
AT+UPSD=0,3,"web"
