FAQ

Got questions about our SMS API?

Everything you need to know to get started.

What's Devotel's delivery rate for SMS?

Devotel maintains a 99% delivery rate for SMS messages globally, backed by our extensive carrier network and intelligent routing technology.

Do you charge for failed messages?

Our pricing is based on message transmission rather than successful delivery, as costs are incurred with carriers regardless of final delivery status. However, with our 99% delivery rate, failed messages are rare.

In which countries do you provision phone numbers?

We provide local numbers in 50+ countries including UK, Spain, France, Germany, US, Canada, Australia, and major markets across Europe, Asia, and Latin America.

What happens if your API goes down?

We guarantee 99.9% uptime backed by multi-region redundancy. If our primary region fails, traffic automatically routes to backup regions with zero manual intervention.

What kind of support do you offer for migrating from another provider?

We will assign a dedicated migration specialist to handle your transition to our platform. Combined with our 24/7 support team, we ensure a smooth migration with minimal disruption to your operations.

How fast are messages delivered?

Average global delivery time is less than 3 seconds. Authentication messages (OTPs) using our priority routes are delivered even faster. You receive real-time delivery confirmation via webhooks.

Do you support two-way SMS?

Yes. You can receive customer replies via webhooks, build SMS chatbots, and enable real-time conversations.

Can I port my existing phone numbers?

Yes. We support number porting from all major providers. The process typically takes up to 24 hours. We handle all paperwork and coordination with your current provider.
