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
✅ Compatible with virtually all mobile phones

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:

Register your sender ID
Adapt your message content
Comply with local regulations

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

RCS — expanding global coverage

RCS is a fast-growing channel that enables rich, interactive messaging experiences directly in the native messaging app.
