I am using RC7620 and JIO sim card to send sms.  
While sending SMS it takes long time to return an error 350.

below are the cellular module details and its status

OK

In the gstatus i can see the cellular module is not registered for IMS services.  
Please let me know how to make this module register for IMS services.

Hi ashishkamble005

Please try to download the latest firmware to module and retry.  
You can get it here [RC76xx Firmware Release 8](https://source.sierrawireless.com/resources/airprime/software/rc76xx/rc76xx-firmware-release-8/#sthash.Qk037YGY.dpbs)

I can send SMS successfully on RC7620 firmware SWI9X07H\_00.08.07.00.

@Donald  
Me too able to send SMS using other operator simcard like Airtel, Vodafone.  
Jio network is having only LTE infrastructure. No support of older technologies.
