SMS no error but not send

IoT Modules HL78
1

On my HL78 ( version HL7802.4.6.9.4), i try to send sms with AT command.
I’ve no error but the modem do nothing !

When i want to write a SMS on memory with the command AT+CMGW=“0612345678”, the HL78 say OK, but nothing in the list message ( AT+CMGL=“ALL” )

And when I try to send directly a message with the “AT+CMGS” command, I’ve a OK but nothing was send.

I try to change the message storage with AT+SPMS, but it does nothing.
The Service Center Address is correct.

For information i’m in SMS format text mode.

I’ve try the sim on phone and the sms works !

If you’ve got a idea…
