Overview
The Skyetel Network can enable your phone numbers for SMS and MMS. This feature allows you to send and receive a SMS or MMS from/to mobile phone networks (like Verizon or T-Mobile).
Getting Started
You can toggle the SMS & MMS enablement from within our portal in the phone number options menu:
You will be presented with three options:
This method allows an incoming SMS or MMS to be converted to an email and sent to a specified address in our portal.
Phone Number
This method allows an incoming SMS or MMS to be forwarded to another phone number (generally a mobile phone)
Callback URL (POST or GET)
This method allows you to receive the SMS or MMS via a call from our API. Messages are sent to your provided callback URL with a JSON body that matches the fields required for sending an SMS or MMS shown below. You can expect at least to, from, and text fields.

Once your phone number is enabled for SMS, it will appear green in our Portal: |
Limitations to SMS & MMS
While our network is able to enable and process SMS and MMS for almost all of our numbers, there are a few limitations to be aware of:
Toll Free Numbers
Our network is not currently configured to SMS enable Toll Free numbers.
SMS Enablement Requires the "State" of a number to be Healthy
Our network does the legwork to prepare a number for SMS enablement as soon as it it's phone number state becomes "Healthy". This insures that we do not accidentally prepare a number for SMS prior to it actually being on our network.
SMS Enablement can take up to 24 hours
While most SMS enablements will be instant, there are edge cases where some phone numbers take longer than others to enable.
SMS & MMS may only be sent via our API
Our network requires you to use our API to send any SMS or MMS.
Short Code SMS is unsupported
Our network is unable to receive short code sms messages
Ineligible Numbers
While most numbers on our network support SMS and MMS, some numbers do not. Specifically, non-US numbers (including Canada - sorry guys) can not be enabled for SMS. There are also a very small percentage of US numbers that are ineligible.
Sending an SMS or MMS through Skyetel API
SMS is sent by generating a specially-crafted request to the Skyetel SMS API and using an SID and Secret you have created for this purpose.
Generating and obtaining an SID and Secret
Skyetel allows you to create your own SID and Secret and later remove it when it is no longer used. These can be generated by visiting your Skyetel portal
Sending a basic SMS or MMS
Here is an example of performing that request using the curl command-line tool:
| Code Block |
|---|
curl -X POST -v \
-H "Content-type: application/json" \
--user <SID>:<SECRET> \
--data '{ "to": "15558001234", "text": "You are awesome" }' \

| Info |

In the to field provide your the correct 11-digit destination phonenumber; and provide you SMS-enabled source phonenumber in the from field. |
