When registering in SafeUM, a User is given a telephone number in a +3712 ХХХ-ХХХХ format (further – The Number).

In case of a User:

  • doesn’t recharge The Number through 2 weeks (14 days) from the registration date

Withdrawing The Number doesn’t impact on the User’s account functionality (including chats and calls within SafeUM to other SafeUM’s Users).

The recovery of The Number is technically IMPOSSIBLE.
