To buy virtual numbers for Mailgroup, you need to:

• Contact technical support to review and confirm (verify) your account for the purchase of numbers through any communication channel available to you.
• We do not recommend that you replenish the balance before your application is considered. In some cases, the application may be considered up to 7 days.
• Purchase from 1000 numbers per month.

In other cases, it is not possible to buy numbers to activate Mailgroup. By going to the "Rent" tab, you can purchase a number without restrictions.

Refunds for the OLX service are not provided, including the fact that the account is busy, as this happens due to the reissue of the SIM card by the mobile operator that used to have a profile.

Recommendation for registering the OLX service from the sms-activate command:

• Buy a number through the site interface or API.


• Before receiving the code, check the availability of the account (either through the password recovery form, or directly, trying to enter the account by entering any password). Make sure the number is not busy, and only then ask for the verification code.


• If during the check (with a checker program or manually) it turns out that your personal account is busy, then cancel the purchase. The funds will automatically be returned to your balance (a successful purchase is considered only the one that has received SMS from the service).

To purchase at "Wholesale" prices, you need to be a member of the loyalty program. More about the loyalty program

What is number rental?

Number rental lets you receive SMS on a real phone number exclusively assigned to you for the duration of the rental period.

Unlike one-time activations (valid ~20 minutes), a rented number stays yours for a minimum of 4 hours up to 4 weeks, perfect for services requiring ongoing SMS access.

Key benefits

• Exclusive use — no one else receives SMS on your number during the rental
• Receive unlimited SMS from the chosen service
• Ideal for services requiring repeated verification
• Number automatically released after the rental period ends
