The Smstools SMS gateway connects your software directly to the mobile network. Direct connections with operators, 99.99% uptime SLA and pay-as-you-go rates — no SIM card, no subscription.
An SMS gateway is the connection point between your software or system and the mobile network. Via the gateway your application sends SMS messages without a SIM card or GSM modem — purely via the internet. Technically, an SMS gateway uses the SMPP protocol to communicate with operators. You connect your software to our gateway via our SMS API. Smstools offers direct connections with operators and 2000+ operators worldwide.
At Smstools you use our REST API to connect to our SMS gateway infrastructure. You do not need to manage the gateway yourself. View our SMS API →
When you send an SMS via our API, our gateway automatically processes the message: validation, route selection and direct delivery to the operator. You receive a delivery report via webhook as soon as the message is delivered.
