The Problem

Legacy SMS
Is Broken.

Four critical failures that cost East African businesses millions, and legacy providers won't fix them.

System Unreliability

Frequent drops and latency spikes during your highest-volume campaigns. The moment it matters most, legacy providers go dark.

The DLR Blackhole

Messages disappear with no trace. Providers can't, or won't, return accurate delivery reports. You're flying blind.

Built for Telco Engineers

Interfaces designed in the early 2000s. High friction for marketers, painful for developers. No one wins.

Zero Actionable Analytics

"Sent" is not the same as "Delivered". Legacy providers give you a number and call it a day. No insights. No optimization.

The Sema Link Difference

Single One.

Not another reseller. An intelligent, user-first communication platform built from the ground up by people who lived inside the problem.

Guaranteed DLR Processing

99.9% Uptime SLA

Horizontally scalable infrastructure engineered to handle East African peak traffic without breaking a sweat.

Consumer-Grade UI
