SMS Gateways & Messaging APIs
SMS gateways and messaging APIs send and receive text messages from your app, CRM or campaign platform. What matters is the route and the rules: the countries covered, which sender types are allowed there, the registration each country requires, throughput limits and how delivery reports come back. Every listing is a provider service or integration, and sending must be opt-in or otherwise lawful.

FAQ
Can I send SMS marketing without opt-in?
No. Messaging on TrafficNodes must be permission-based or have another lawful basis, and most countries require registration of senders and templates.
What is the difference between a gateway and a reseller?
A gateway operator connects to carriers directly; a reseller or partner resells access to one. Both can be fine: the listing states which you are buying and who you contract with.
