SMS questions

Useful checks before contacting support.

The message appears in GHL but no SMS arrives

Check the chosen channel, recipient number, mobile connection, SIM and SMSMobileAPI sending log. A queued request is not yet proof of delivery.

The phone received a reply, but GHL has not shown it

Check received-SMS permissions and connectivity on the mobile first. Then verify the GHL transfer log, linked sub-account and contact number.

Can I use several connected mobiles?

Yes, according to your account capacity. Test each mobile and incoming route before using it for a customer workflow.
