You need to have added and successfully verified test phone numbers in your account before you will be able to receive test SMS messages. Submitting test messages to a destination other than the test phone numbers registered will return a simulated response which emulates what the response will look like in your system.
You can add a maximum of three test phones to your account. To add a test phone, navigate to My Workspace --> SMS and select 'Manage Test Phones'. Test phones can also be set up as part of the new integration wizard.
If you have added at least one test phone to your account, a Test Phones card is added to the My Workspace tab. Select this card to add, view, update or remove test phones in your account. Note that if your test phone has an ‘Unverified’ status (i.e. has not been verified successfully), you will not be able to send messages to this phone number and have to remove it before trying to add it again.
Once you've configured an integration for testing in our sandbox environment, you need to ensure that your test number is linked to the integration before messages will be delivered to your test phone number. Submitting test messages to a destination other than the test phone numbers registered will return a simulated response which emulates what the response will look like in your system.
To double-check that your sandbox integration is linked to your test number, open your integration from the SMS integrations page, and select the ‘Phone numbers’ tab at the top of the page. Your test numbers will be listed here. Numbers with a green tick box are linked to your integration. Click on the tick box to link or unlink your test number to this integration. Test messages will only be delivered to a test phone if your number is linked here.
