Frequently asked questions

Check out our Knowledge Base page for more FAQs

It becomes credit on your prepaid account, and O2 takes the price of your booked pack out of that credit every four weeks. The o2 Prepaid Smartphone Packs cost 9,99 EUR for S, 14,99 EUR for M and 19,99 EUR for L per four weeks, so a 15 EUR top-up covers one M cycle and 20 EUR covers one L cycle.

Six months from each top-up. Every new top-up restarts the six-month window for your whole balance.

Dial *101# on the handset. On the tariffs in O2's current prepaid portfolio this account check is free. To see how much longer the credit itself is valid, dial *102# instead.

Your SIM stays active as long as you use it at least every six months, either by topping up or by a chargeable action such as making a call. After a deactivation you have three months to ask for any remaining credit to be paid out.

Yes. You buy the top-up on Bitrefill and pay with Visa, Mastercard or American Express, Apple Pay or Google Pay, alongside crypto. Card and wallet payments are available in certain regions only, so the methods you can use depend on where you are.

Dial the free short code 5667 from your O2 prepaid number to reach the prepaid voice menu, which is open around the clock. The O2 prepaid hotline is 017688855282, Monday to Friday 7:00 to 20:00 and Saturday 10:00 to 18:00. You can also use Mein O2 or the Mein O2 app.

O2 does not accept crypto, but you can top up your smartphone on Bitrefill using Bitcoin or other cryptocurrencies.

A mobile airtime top-up should be added to a phone number within a few seconds to minutes. Sometimes, there may be a small delay on the part of the mobile operator, but rest assured, we will send you an email confirmation as soon as your top-up has been processed successfully.

Some alternatives that customers consider in Guinea usually are Orange Guinea-Conakry, MTN Guinea-Conakry and Cellcom. You can find many other options by visiting the phone refill section on our website.
