About Onet
Onet asks for a phone number when you create an account or when it wants to confirm it's you. A separate number keeps your personal one private, and works when you don't have a SIM card from the right country.
kartesim has Onet numbers in 8 countries right now, from $0.032 per code. You pick the country, enter the number in Onet, and the code shows up on this page.
How Onet sends the code
Onet usually sends its code by SMS to the number you enter. Our numbers receive SMS only, so if Onet offers a call instead, ask for the SMS.
When the Onet code doesn't arrive
- The number was already used on Onet, so Onet refuses it or sends the code somewhere else. Take another number.
- You asked for the code several times in a row. Many apps make you wait longer after each try.
- Onet chose not to send to this number or country. Cancel for a full refund and try another country.
Tip: Ask for the code once and keep this page open. If nothing comes within a few minutes, cancel and take a number from another country.

- The code shows up on this page within seconds. No code means no charge.
Questions
- What is a Standard number?
- A number from our wider stock, with many more countries and lower prices. It works for most services. If Onet doesn't send the code, you pay nothing. For apps that refuse virtual numbers, pick a country with real SIM numbers.
- Which country is best for Onet?
- Brazil has the most Onet numbers online right now, and United Kingdom is the cheapest at $0.032. If a code doesn't come, cancel for a refund and try another country.
- What if the code doesn't arrive?
- You don't pay. Cancel the order, or let the number expire, and the full price goes back to your wallet.
- How do I pay?
- Top up your wallet once, from $5.00, and each code is paid from your balance. You don't need an account first: your email is enough. Top up $20.00 or more and get up to +15% extra credit.
- Can I keep the same number longer?
- No. A one-time code number is for one activation.
