With Campaigns, you can reach your audience across multiple messaging channels — but availability depends on the channel, the destination country, and local regulations.

Here’s how each channel performs globally.

SMS — global coverage

SMS enables you to reach customers almost anywhere in the world.

✅ Available in 200+ countries and territories [community.sinch.com]
✅ Supported across thousands of carrier networks

This makes SMS the most reliable option when you need to communicate at scale, across multiple markets.

👉 What to keep in mind
Messaging requirements vary by country. Depending on the destination, you may need to:

Comply with local regulations

👉 You can find detailed requirements in the Country Information section of the Sinch Customer Dashboard.
