We connect directly with the operators using the protocols of their choice. Mostly IP-based protocols such as SMPP, SIP, MM7 and various kinds of VPN/TLS technology.

Very custom contracts and back in 2011 when we started there was no such thing as a virtual mobile phone number.

These days the operators are a bit more aware of the value of A2P (application-to-person) versus P2P which was/is very much on the decline. That also means the operators have capacity built of ready to be used without new investments.

As for our own software, we are mostly a Python based shop. And we use tons of open source. The most heavily used components we replace over time with cusomized software as these are generally fully not suited for our needs.

The true value for our customers is our technical support, our operator conectivity, the robustness of the platform, and lastly the nice REST API with it’s debugging capability.
