Essentially, o2 offers two types of SIM cards: Prepaid and Postpaid.
Prepaid is very flexible, as you only buy credit for your SIM card whenever you need it. However, you also do not get as much data as you could with a postpaid plan. These are O2’s current prepaid plans:
- O2 my Prepaid 9 Cent: 0.00 GB | 9 Cents per minute or SMS | 99 Cents per day for data – 0.00€ / 4 weeks
- O2 my Prepaid Basic: 0.15 GB | 9 Cents per minute or SMS – 1.99€ / 4 weeks
- O2 my Prepaid S: 3.5 GB | unlimited minutes and SMS to all German numbers | EU-Roaming included – 9.99€ / 4 weeks
- O2 my Prepaid M: 6.5 GB | unlimited minutes and SMS to all German numbers | EU-Roaming included – 14.99€ / 4 weeks
- O2 my Prepaid L: 12.5 GB | unlimited minutes and SMS to all German numbers | EU-Roaming included – 19.99€ / 4 weeks
- O2 my Prepaid Max: 999 GB | unlimited minutes and SMS to all German numbers | EU-Roaming included – 69.99€ / 4 weeks
You can buy more o2 credit online or in a German supermarket, gas station or other shops.
Check your o2 balance by typing the following code and press the call button: *101#
Postpaid is usually a 24-month contract, which means you need to commit to o2 for 2 years and you can only cancel your contract if you leave Germany to permanently live in a different country. Therefore, postpaid is a little less flexible, but usually also gives you more for your money. Sometimes, you can select a “flex-option”, which means that you can cancel your contract every month, but in turn you have to pay a higher monthly fee (usually 5€ more per month).
o2 Germany also offers a free bank account with a special perk: For every Euro you spent with your Mastercard, you get 1 MB bonus data that you can redeem with your o2 contract. Find out more about this offer here.
If you just need mobile data for your tablet or laptop, you can look into the o2 my Data plans. These SIM cards you can use for your tablet or computer (by using a surf stick), without using your smartphone data. Below you can see an overview of the different plans.

I bought a contract sim O2 for two years without bank account after firstly arrive in germany. Actually I was not properly informed about the contract. Recently I am in Bangladesh for above 7months and did no pay the monthly bills. A few days age the O2 deactivated my sim and I can not log in my account through O2 apps. My question is : will this kind of activities affect my SCHUFA score negatively? Can a person enter into a contract without providing own bank account? I am really worrying about this situation. Actually the O2 shop did not inform me properly. I wanted prepaid but they gave me postpaid.When I bought the SIM I did not have any bank account and anmeldung papers.I had just arrived in Germany with 6 month visa. How could they let me enter into this contract without above requirements? If you can please inform me. Thanks

Hi,
How to check my postpaid balance with USSD code while I’m in roaming?
Check your o2 balance by typing the following code and press the call button: *101# – this one doesn’t work for postpaid.
I want to see if I have additional charges except my plan.
Thanks,
Dragana

Hi
I would like to ask, whether you can freely swap back on a cheaper prepaid plan for the upcoming months, in case you once needed more available data for one month but no longer require it for the future.
Let me set an example from real life:
1. My girlfriend bought an “O2 my Prepaid M” plan for March, but she might need to upgrade to “O2 my Prepaid L” soon, because she uses her phone a lot and requires more available data for this month.
2. After she switches to the “L” plan, would she be able to switch back on “M” plan for the next month? If yes, will that be as easy to do for her by herself as upgrading from “M” to “L”? Or she will need to contact some responsible person?

What numbers (other than the phone number, of course) or wording are required to send a text message to an o2 subscriber?
MyGermanPhone
You just type in the phone number and your text, then send it. That’s all

I realised that I was charged about 29 Euros for my postpaid in November. But in December I was charged 45 Euros for the same postpaid. Please what could be the reason for this?
How can I use the services of O2 so I can pay less as just like it happened in the November services.
Thank you
MyGermanPhone
This might be due to your personal usage, maybe some roaming in a non-EU country? Or use of MMS services. Please contact O2 customer service and ask them about it.
