If you have no commitments, or notice period with the provider you are leaving, we will transfer your number within three business days.

Day 0
We receive your request for a number transfer and the OKU number. We'll send the order for a number transfer to the operator you are leaving.
Day 1
The operator you are leaving confirms the OKU number and releases your phone number for transfer.
Day 2
The number is recorded in the central database of transferred numbers.
Day 3
Your number is active on O2.

While the number is being transferred, your SIM card might be temporarily unavailable.

Detailed information about transferring numbers can be found in the general terms and conditions for customers with a postpaid tariff, and forcustomers with a prepaid card.

What is a OKU number?

This is a 14-digit number that serves as a transfer authorization code. OKU is an abbreviation for a notice number from the operator you are leaving. This number is always generated by the operator you are leaving.
