O2 Mobile Top-Up
O2 is a major mobile brand operated by Telefónica, one of Europe's largest telecommunications companies. In Europe, O2 operates under the Telefónica group in both Germany (as O2 Germany / Telefónica Deutschland) and the Czech Republic (as O2 Czech Republic — now partly rebranded under PPF Group ownership). In Germany, O2 runs its own 4G LTE and 5G network covering major cities and motorway corridors, while in the Czech Republic, O2 operates a separate national mobile network serving Prague, Brno, Ostrava, and cities throughout Bohemia and Moravia. Both operations are distinct entities with separate ownership.
An O2 top-up adds prepaid Guthaben (Germany) or kredit (Czech Republic) to your SIM for calls, texts, and data. Whether you're a tourist visiting Berlin or Prague, or a local on a pay-as-you-go plan, buying credit online is faster than finding a store.
SmartCDKeys lists O2 vouchers from both Germany (EUR) and the Czech Republic (CZK). Select the right country and denomination when purchasing.
