How it works
A number in four steps.
No carrier store, no paperwork, no waiting. From signup to your first message in under two minutes.
01
Pick a country & number
Browse available local numbers across our launch countries. Real local prefixes — not virtual numbers with hidden limitations. Choose the one that fits where you are or where you're going.
02
eSIM delivered instantly
No physical SIM card, no shipping address, no waiting. Your number arrives as an eSIM profile. Scan a QR code in your phone's settings and you're live within seconds.
03
Register on any app
Use your new number to register or verify on any internet-based messaging or calling app — the same way you'd use any mobile number.
WhatsApp Viber Signal Messenger Telegram
04
Manage from one dashboard
Add numbers for your whole team, assign roles, track usage, and manage billing — all from the tel-os web or mobile app. No IT team required. Cancel any number, any time.
Who it's for
Built for two kinds of people.
Small teams that need professional numbers, and individuals who want a second number without the complexity.
Small Business
Teams that sell & support
Real estate agents, marketing agencies, startups — any small team that needs dedicated work numbers without the hassle of a traditional business phone plan.
  • Real estate agents with a dedicated client-facing number
  • Sales reps — one number each, managed from one dashboard
  • Customer support teams with a shared inbound number
  • Marketing agencies managing client communications
  • Startups that need to look established from day one
Individuals
Second number, zero hassle
Travelers, freelancers, remote workers, and anyone who wants a separate number for apps — without carrying two phones or getting a second SIM card.
  • Local number on WhatsApp or Viber while abroad
  • Separate work/personal number on a single phone
  • Privacy number for listings, dating apps, or side projects
  • Freelancers keeping clients off their personal line
  • Remote workers needing a local presence in client countries
