Replaces Twilio
European alternatives to Twilio
SMS APIs from European communication providers
Browse the category: SMS APIs
Twilio is a communications platform that lets applications send and receive SMS messages, place and answer phone calls and use related channels through an API. Developers use it for one time passcodes, delivery notifications, appointment reminders and support call flows, without having to contract with mobile operators in every country themselves.
Phone numbers and message logs require careful handling. GatewayAPI is verified as controlled by a Danish-owned group and offers a separate EU setup. seven, sms.to and smstools provide other messaging APIs, but their ultimate ownership remains unresolved in this review. Compare the intended destinations, core hosting, support access and channel-specific processing before selecting a replacement for Twilio.

Do these SMS providers deliver worldwide?
Routes and coverage differ by provider and by destination country, so this is the first thing to check. GatewayAPI, seven and smstools publish coverage and pricing information for the countries they serve.
Can I use a sender name instead of a number?
Alphanumeric sender IDs are widely supported, though the rules vary per country and some require registration. Confirm the requirements with sms.to or GatewayAPI for your target markets.
What about voice calls?
The options listed here concentrate on SMS rather than the full range of channels Twilio offers. If voice is essential, keep that requirement separate when you compare seven and smstools.
