Thanks to the O2 App, you always have your consumption under control, you can arrange a new flat rate or SIM card, set up an O2 Spolu group full of benefits, pay your bills or get nice surprises.

Being in the O2 Spolu group is worth it. The more programs you combine in the group, the more benefits you can enjoy together. You can get a financial reward of up to €10 per month, extra data for all members after using up your prepaid data or even extra data outside the EU. And O2 Surprises are more advantageous for all members.
With the new O2 Connect service, you can share data, calls and SMS/MMS from your flat rate with other smart devices, such as a tablet or smart watch.

I hate the system of activating and deactivating of data packages. It always renews whdn I do not expect it to, so I always pay double the price, since I need it 3x a year. Funny that it can send me unnecessary advertisements, but not a message about the package being close to expiration.

Hello. If you have more than one phone number linked to the same ID, you can easily switch between them in our app. Just tap the arrow in the top left corner of the main screen. Your phone numbers will appear in a menu, and you can select whichever one you want to manage.

No English language is available in the app. For a multinational company in the EU, this should be standard please fix this!
