CEREG: Reject - #14 "EPS services not allowed in this PLMN"

[optical]

Hello,

we are experiencing rejection from the network by receiving cereg notification. Modem afterwards stops attempting to connect to network. Which results in application getting stuck due to this unhanded case.

How should we proceed when this case is encountered ? Does the modem needs some additional at commands to recover ?
Can we somehow set the modem to keep trying after this event ?

Thank you

Is it possible that some BTS have the EPS disabled and will signal rejection ?

Reject cause #14 comes from MME, hence there should not be any difference between the eNodeB's. You need to talk to the carrier regarding this.

optical said:

How can we initiate connection to this network after rejection ?

The network code is stored to "list of forbidden PLMNs for GPRS service" which will be maintained until +CFUN=0, SIM card removal, or expiry of T3245 (random 12-24h if timer usage is enabled by SIM card). You could try +CFUN=40 as well, although I'm not quite sure if that will work.

Cheers,

Markus

We will try to contact our carrier.

When we get another device with this behavior we will try the +CFUN=40 approach.
 +CFUN=41 Will again activat the UICC. Will the modem then start again the search for the network ?

There are no other commands required after deactivating the UICC to restore previous behavior(Subscription to notifications, etc.) ?
