O2 top up from anywhere

A O2 top up on ReloadTo adds euro credit to a O2 prepaid line in Germany, for your own number or someone else's, from Germany or abroad. You need no O2 account and no local card. O2 top-ups range from $17.85 to $59.93 USD, with no extra fees. People search for it as “o2 aufladen”.

How to top up O2 online

  1. Enter the O2 number. Enter +49 and the mobile number without its leading 0: German mobile numbers start with 015, 016 or 017 inside the country, so 0151 2345 6789 is written +49 151 2345 6789. Don't add 00 or 0049.
  2. Choose the credit amount.
  3. Pay. Pay with a debit card, credit card or PayPal. Card payments use 3-D Secure, and sometimes we ask you to verify your card before the order is sent.

The top-up is sent automatically once the payment is approved. If a top-up fails, we refund you. A completed top-up to a wrong number can't be refunded, so check the number before you pay.

What you can send to O2

According to our catalog, O2 top-ups are prepaid credit of 15–50 EUR. The credit goes to the line's balance and can be used for the carrier's offers, calls, SMS and data. Each product shows the euro amount and its price in dollars before you pay.

Tips before you top up O2

  • Confirm the line is O2 before you pay: the first digits are not proof.
  • Prepaid only: these top-ups are for O2 prepaid SIMs.
  • See every carrier on the Germany top-up page.
