If you’ve just arrived in Germany, one of your first priorities will be getting connected and for that, you’ll need a German phone number. If you are looking for information about mobile phone contracts, here is a short guideline to help you get started:
Prepaid SIM Cards Most SIM cards can be obtained in supermarkets or local shops for around €10 without proof of address.
Contract ("Postpaid") SIM Cards If you have already registered your residence, you will be able to sign up for a contract with one of the German mobile phone providers.
Choosing a Provider There are several mobile providers in Germany; you can compare their coverage, prices, and customer reviews on online platforms to find the best fit for your needs.
Data, Calls, and Texts Mobile plans include a certain amount of data, minutes for calls, and SMS texts. Make sure to select a plan that meets your usage requirements.
Contract Duration Contracts can vary in duration; those which run for a specific period are often cheaper at first glance, but when you sign a contract, you are less flexible, and you cannot just switch to a more appropriate or less expensive deal. The minimum contract period is usually 24 months for postpaid plans. Some providers also offer shorter contract options.
Cancellation Terms Be careful about the terms and conditions for canceling your contract. In most cases, you need to give notice in advance, usually 3 months, if you want to terminate your contract before its expiration.
Identification Be prepared to provide identification when signing a contract, such as your passport or ID card. Some providers also do this via a video call.
"I Already Have a Phone Plan from Another EU Country!"
Great! In most cases, you should be able to use your phone as it is without roaming charges and be able to surf with mobile data (of course, check the conditions of your mobile provider). You might not need to get a German phone number if you are staying for a short time.
The EU has the "roam like at home" policy, which means: The same rule also applies to any calls or text messages you receive while you're abroad, you aren't charged extra to receive calls or texts while roaming, even if the person calling you is using a different service provider. Please keep in mind that even though the UK, Norway, and Switzerland are usually not covered by these plans, some phone contract providers in Germany have plans that cover them too.
"I Am Totally New and from a Country That Is Not Within the EU Free Roaming Zone"
Most supermarket chains in Germany have their own brand of prepaid SIMs that can be activated without having to show proof of address. Since they are affordable, you might choose to get one until you get another plan.
