Overview
Number Hosting (Hosted SMS / Hosted Messaging) allows you to enable SMS/MMS messaging on phone numbers you already own with another carrier, while continuing to use LC for messaging.
Your phone number remains fully active with your original carrier for voice calls, but text messaging (SMS/MMS) is routed through LC.
This setup is ideal for businesses that want to keep their existing phone numbers while leveraging LC’s messaging capabilities.

Number Hosting enables SMS/MMS functionality on externally owned phone numbers without transferring voice services.

How Number Hosting Works for LC Phone Locations
To activate Hosted Messaging in LC, a strict verification and authorization process to prevent fraud and ensure carrier compliance is required.
Required Steps (Completed by the End User / Number Owner)

Once Twilio approves these steps, Hosted Messaging routing is activated, allowing SMS/MMS to function inside the LC phone system.
