SMS gateways are used by CommCareHQ to send and receive text messages. Each SMS gateway is represented by a phone number - normally a gateway is setup for each country, but some gateway providers will let you send messages to many countries. Details on our SMS gateways can be found here (Gateway Options to Set up an SMS Project).

Set Up A Telerivet Account
When creating your Telerivet account, check to see where your project falls under Telerivet's pricing. It is important to set up the right pricing structure before your project goes live. For example, it's important to ensure that the number of contacts you will be sending to falls within the limit allowed on the account.
...
If you want to set your Telerivet pricing to a non-free plan, make sure that when you use your credit card to add funds to "Select a plan" that you want to use.
Set Up A CommCare Account
Once you have a phone and set up that meets this criteria, log into CommCare

Managing Your Telerivet Gateway
Setting up Back-up Connectivity
By default, Android phones won't automatically switch from Wi-Fi to mobile data if the phone is connected to the Wi-Fi network but the Wi-Fi network isn't connected to the internet. The Telerivet Android app lets you override that. From the Phone Settings screen in the Telerivet Android app, scroll to the bottom and enable "Network failover". Then Telerivet will automatically switch the phone from Wi-Fi to mobile data if it can't connect to telerivet's servers via Wi-Fi. This may use more airtime but will result in a more reliable connection.
Managing Stored Message Volume
It's important to be aware of the maximum number of stored messages that your Telerivet plan allows. For example, the Test Telerivet plan only allows 500 messages to be stored in the account, so after sending and receiving 500 messages total, the account will stop sending new messages until old messages are deleted. To have your Telerivet account automatically delete old messages, you can update the "Message Retention" setting for your Telerivet project (Dashboard -> Edit Settings).
- When sending outbound SMS, you may need to throttle the rate at which you send SMS in order to comply with regulations in the country you are sending. A good rule of thumb is to not exceed the rate of 1 SMS per second, though you should check with the regulations in the country you wish to send SMS. In order to enforce the rate limit, in the Telerivet Android app, go to Phone Settings -> Message Sending Parameters -> Delay after message sent (ms), and enter the number of milliseconds to wait between sending each SMS. For example, enter 1000 to send SMS no faster than the rate of 1 SMS per second.
- No matter what plan you sign up for with Telerivet, there is an initial limit of 100 outgoing SMS messages an hour. This is important to be aware of, especially for larger project or big training days when a lot of SMS messages will be sent in a short period. In order to change this, open the Telerivet app on your Android phone, click SMS rate limit, and install an SMS expansion pack(s). Can download multiple.
If you have a large project, it is likely that your Telerivet gateway phone will eventually hit a memory capacity from storing all incoming and outgoing messages. To avoid this, you'll want to change the settings on Telerivet's website. Log into Telerivet, click "Phones" on the left side panel, select the phone that you are using, click "Edit Settings" on the top right, and click the following question from "Yes" to "No."
...
- You can setup email notifications when a phone gets disconnected or has errors by adjusting the settings for the phone on telerivet.com. To do so, click Edit Settings on the Dashboard when logged into telerivet.com and adjust the Email Notifications. You can also click on the page for the phone on telerivet.com and click Edit Settings there for some additional Email Notifications.

Step 3 - Registration of Contacts
You still register your contacts in CommCareHQ the same way as you would if used any other SMS gateway. Information on registering mobile worker contacts is here, and information on registering case contacts is here.
...
Notifications
You can setup email notifications when a phone gets disconnected or has errors by adjusting the settings for the phone on telerivet.com. Read more here.
You can request a message delivery report from Telerivet, meaning Telerivet will notify CommCare once a message has been delivered to its intended recipient(s). CommCare will then update the respective message logs accordingly with a "Delivered" status. This is useful when you need to know which or whether recipients have received the message. To enable this, sign in on telerivet.com → click Routes → Select the appropriate route → click Edit Settings → make sure the checkbox under "Delivery Reports" is checked.
(Optional) - Share Your Telerivet Gateway with Another Project
If you have already set up your Telerivet gateway on CommCareHQ, you may want to share it with another project. To do this:
Log into your original project space in CommCareHQ, and navigate to Messaging -> SMS Connectivity.
Select your pre-existing Telerivet Gatway and click
.Under "General Settings," check the box that says "Give other domains access." In the next question, type out the name of the project.
...
In the new project, make sure that you click "Set As Default" for the shared Telerivet gateway (example below called cc-messaging-test)
