If SMS to Email is enabled on your phone number you can then send and receive SMS using your DID. You will send the SMS message through your email account and the recipient will receive it to their phone as an SMS message. When someone sends an SMS message to your phone number you will receive it as an email. To send an SMS message through email follow the below example:
Open a new Email
In the "To" box type F4129271503-T4122460700@mysmsforward.com
In this example F4129271503 would be your DID with SMS Enabled
T4122460700 would be the number you are sending SMS to
The body of your email will be sent as the SMS message.
The subject is not needed and will be ignored
The sending email address will also need a valid SPF record or the message will fail
