REST API and webhooks

One prepaid balance
Numbers, renewals and SMS are paid from the same balance as your eSIMs. No invoices to chase, no surprise bills.
Fraud kept out
Premium-rate ranges are refused before any charge, and every SMS abroad is priced per country above what it costs, so pumping cannot run up your bill.

Questions and answers
What are wholesale phone numbers?
Real mobile and local phone numbers that you buy at wholesale prices and resell to your own customers under your brand. Each number receives SMS and calls, can send SMS, and is managed from the Fully Signal partner panel or the REST API.
How much do the numbers cost?
paid 1, 3 or 12 months at a time depending on the location, with longer plans cheaper per month. Incoming SMS and incoming calls are free and unlimited. Outgoing SMS cost a small fee per message part. Any available number has no setup fee where the network charges none; choosing a specific number has a small one-off fee, shown per destination. There is no account fee, no monthly platform fee and no commission: you set your own retail price.
Who can resell phone numbers?
Any business with a free Fully Signal partner account and funds on its balance. Phone numbers need our approval: you ask from the Phone numbers page of your partner panel, and we email you the answer. Once approved, the minimum single deposit on your account becomes €150, and numbers are paid from the same prepaid balance as eSIMs.
Will my customers see your brand?
No. The service is white label: your customers deal only with you, and the numbers, SMS and calls carry no Fully Signal branding.
How do calls work?
Incoming calls to a number are forwarded, free, to any SIP address you choose: your own phone system (PBX), a softphone app or your customer's SIP account. Outgoing calls from the numbers are available on request for partners with their own SIP platform.
Can I automate it through an API?
Yes. The REST API lists locations and prices, searches available numbers, buys a number (with an idempotency key), sends SMS, reads messages, forwards calls and cancels numbers. Incoming SMS also arrive on your webhook as signed number.sms_received events.
Where can the numbers send SMS?
Each number sends SMS to numbers in its own country (a UK number to +44 numbers, for example), and to other countries, each at its own price per SMS. Premium-rate numbers are blocked. Receiving SMS works from anywhere.
Can the numbers receive verification codes?
Yes, most services send their codes to these numbers without trouble. A few apps refuse virtual numbers by policy, so test the service your customers need first.
What happens if my balance runs out?
A number whose renewal cannot be paid is suspended: its new SMS are kept but locked. Add funds within 7 days and it renews and unlocks automatically; after that the number is released. You get an email and a number.suspended webhook first.
