Can this SIM card send and receive SMS on another device or phone?
Which firmware version are you using? If you are not on the latest firmware, please download the latest one and retry. HL78xx (HL7800/HL7800-M/HL7802) Firmware
I can send and receive SMS successfully on HL78XX firmware HL7800.4.6.8.0

OK
But I’ve always CMS ERROR 315 when I send SMS.
Is there specific parameters to set in Sim card ?
And how to found what generate the “CMS ERROR 315” in the HL78 ?
What unit and firmware are you using? Also what bearer are you on? 2G with HL7802 yes it should work, M1 maybe, NB1 it won’t work (as there is no SMS on M1).
That’s the problem !
I’ve configured the parameters on the SIM to be able to send SMS. and SysmoCom Sim card are able to send SMS ( dixit specifications )
Wich SIM parameters are wrong for the HL78 and how to know ?
