What Is an ULTRA Number?
An ULTRA number is a permanent phone number you own for as long as you keep paying the monthly fee. Unlike one-time verification numbers or short rentals, ULTRA numbers are real, stable, and come with both two-way SMS and voice calling. They are built on tier-1 carrier infrastructure, so call quality and delivery rates are dependable.
Key Features
- Two-way SMS: send and receive text messages directly in your dashboard, not just receive OTPs.
- Voice calling: make and receive calls from your number with full call history.
- Local number types: choose from local geographic numbers to establish presence in specific markets.
- Permanent ownership: the number stays yours month after month as long as the fee is paid.
How Pricing Works
ULTRA numbers follow a simple two-part model:
- Upfront fee: paid once to acquire the number.
- Monthly fee: keeps the number active. The monthly cost includes a substantial service markup on top of the raw carrier cost, reflecting the premium voice/SMS capability and stability.
Because voice and SMS lines cost more to provision than data-only services, the markup on ULTRA numbers is higher than on other products in the platform. The exact upfront and monthly amounts are always displayed on the marketplace before you buy.
Business Use Cases
- Client-facing lines: give customers a local number they can actually call and text.
- MFA for your accounts: a stable number that re-verification flows never break.
- Global presence: hold numbers in multiple countries to look local everywhere.
- Campaign SMS: send two-way text campaigns with a number you control end to end.
Getting Started
Browse the marketplace, pick a country, and confirm the upfront and monthly costs. After purchase the number appears in your dashboard with its call log and messaging panel ready to use. If you plan to keep it long term, simply keep the monthly fee paid and the number stays yours.
