You can choose a new number in the platform, connect an existing number or integrate a compatible phone system through SIP. Availability, documentation and carrier cost depend on the country and number type.
Choose a new number
Search available countries and regions in the dashboard. The recurring price and capabilities are shown before purchase. Some countries require identity or business documents before a number can be activated.
Keep an existing number
Depending on the use case, you can:
- verify an existing caller ID for outbound calls;
- route an existing phone system through SIP; or
- port an eligible number to the supported carrier setup.
Do not cancel service with your current carrier before a number port is complete. Cancelling early can cause the number to be released or become unavailable.
Variable costs
These items may be separate from the plan’s AI voice rate:
- monthly number rental;
- destination- or origin-dependent carrier usage;
- toll-free, mobile, premium or regulated number surcharges;
- taxes and country-specific registration work;
- charges from your own SIP, PBX or telephony provider.
Supported.tech shows or confirms separate pricing before activation whenever possible. For a country or number type not listed in the dashboard, contact us with the required country, inbound/outbound use and expected volume.
Portability
Eligible phone numbers can be ported when carrier and regulatory requirements allow it. Keep account information, proof of ownership and recent carrier records available; they may be required to authorize the port.
