We’re also sharing information to answer any questions you may have:
1. What is a billing system?
It is the technological foundation that manages everything related to your phone number: it connects you to the network, changes your tariffs, activates minute, data, and SMS packs, applies discounts and bonuses, processes top-ups and deductions, enables and disables additional services, generates notifications, and stores a history of all transactions.
2. When exactly will the transition begin?
On the evening of July 31, starting at 18:00
3. How long will the transition last?
The planned duration is 14–15 hours. If necessary, we will extend this timeframe to avoid launching an unstable system, and we will notify you accordingly.
4. What will be unavailable?
The following services will be unavailable:
-
the Mobiuz mobile app;
-
checking and reloading your balance;
-
activating, deactivating, and checking services via USSD codes and SMS messages;
-
roaming and international calls;
-
changing tariffs;
-
all services related to activating, transferring, or restoring phone numbers, including number portability (MNP) from one carrier to another;
-

5. What should I do now?
We recommend that you top up your balance by 18:00 on July 31.
6. What will happen to the funds in my account?
The billing update will not affect subscriber’s account balances. After the transition to the new billing system and the restoration of all services, subscribers will be able to check their balances and use their funds as they see fit.
7. Will my purchased tariffs and subscriptions be retained?
Yes, all active minute and data tariffs, as well as subscriptions, will be automatically transferred and will remain active.
8. Will my phone number or account number change?
No, your phone number and account number will remain the same—only the internal technology platform within the company is changing.
9. What about roaming during the transition?
Roaming services will be temporarily limited during the transition period. Check our Telegram channel at https://t.me/PRmobiuz for the latest status.
10. Do I need to change my phone settings or SIM card?
No, no action is required on your phone or SIM card.
11. Will credit card payments change?

12. Will mobile services work at all?
Mobile data, voice calls, and SMS will remain a priority.
13. What should I do if the app isn’t working?
The mobile app will be unavailable while billing system updates are underway. Once the work is complete, you’ll need to update the mobile app.
14. Will I be able to add credit to my account?
We recommend adding credit in advance. During the active phase of the transition, the ability to add credit will be temporarily limited.
15. Will the ongoing work affect the quality of mobile data or calls?

18. Will current rates change after the transition?
No, current rates will remain the same. The new platform provides a more modern billing system.
19. What should corporate customers do?
A dedicated support line is available for corporate customers at 0990.
20. Will there be compensation for the inconvenience?
All billing system updates are performed overnight without interrupting core services: voice calls, mobile data, and SMS messages.
