Telnyx Wireless gives you API control over cellular connectivity. Provision SIMs, route data through private networks, enable VoLTE calling, and send SMS — all programmable, all on one platform.

    Order, activate, and manage SIM cards. Group operations, bulk provisioning, and eSIM profiles.
    Cellular data with flexible routing — public internet, Private Wireless Gateways, or public IPs for inbound connections.
    A second line on one phone, or the full Telnyx voice stack on cellular — Call Control, AI agents, recording, IVR.
    SMS, MMS, and RCS on cellular numbers. A real messaging experience — same as any carrier line.
