Once you received your personal SIM card of the provider of your choice, you can buy credit for your phone number. You don’t need credit if you just need to be called by other people, you can even use the SIM card with 0.00€ credit. However, if you want to activate a certain plan, you will have to top up your SIM card first.
You can either buy credit in any German supermarket, at gas stations or at the mobile phone provider stores, or you can buy the credit online.
Buying the credit online is particularly convenient if you need to start using your phone right after your arrival.

Here are the links for the providers’ online credit store:

O2: Official (Registration necessary)

Congstar: Buy credit online

Telekom: Buy credit online

      If you bought ALDI TALK credit, you can only use it with an ALDI TALK SIM card. If you are using an O2 SIM card, you need to buy O2 credit, ALDI TALK credit won’t work even though they use the same mobile network.

    I have a German handy with a Congstar SIM card, which I last used in 2014-15. I’m going to Germany in one week. I tried adding credit from the U.S. via Prelado so that it would work when I arrive in Germany but it did not recognize my phone number. Has my SIM been deactivated? Has my number been deactivated? Any suggestions? Thanks.

      Yes, it has been deactivated. A SIM card that is not being used is only active for 15 months.
      You will need to get a new SIM card.
