Sandbox Testing
SMS
New to TalkNTalk? We provide a staging device you can link to your account to start testing SMS right away — no balance required. Once linked, you can send up to 20 free messages to verify your integration end-to-end before going live.
To request SMS sandbox access, reach out to our team and we'll get you set up:
Request SMS Sandbox Access on WhatsApp → (opens in a new tab)
We also offer a WhatsApp sandbox so you can test your WhatsApp integration without setting up a production number. The sandbox is available immediately — no request needed. Simply connect your number to the sandbox and start sending test messages.
Note: WhatsApp sandbox messages are limited in content for testing purposes. Full message types and templates are available once you go live with a verified WhatsApp Business number.
