Internet in Germany for Students: SIM or eSIM and How Much Data Do You Need?

Moving to Germany as a student is an exciting new chapter. From finding accommodation and getting to university to staying in touch with friends and managing everyday tasks, having reliable mobile internet can make your first days much easier.

If you are planning to study in Germany, you may be wondering:

• How can I get internet as soon as I arrive in Germany?

• Should I use a local SIM card or an eSIM?

• How much mobile data does a student need?

• Do I need a German address to get a SIM card?

• Which mobile network is best in Germany?

• Can I keep using my Georgian or home-country number together with an eSIM?

In this guide, we explain the main options and help you choose the right internet solution for your stay in Germany.

Why Do Students Need Mobile Internet in Germany?

For students, mobile internet is about much more than social media.

You may need internet for:

• Google Maps and navigation

• Public transport apps and routes

• University websites and platforms

• WhatsApp and other messaging apps

• Email

• Contacting your university or accommodation

• Online bookings and registrations

• Online banking

• Finding important information while you are away from Wi-Fi

Having mobile data is especially useful during your first days in Germany, when you may not yet have Wi-Fi at your accommodation and you are still learning your way around the city.

What Internet Options Are Available for Students in Germany?

Students generally have three main options.

1. Local SIM Card

You can purchase a German SIM card and choose between prepaid plans and longer-term contracts.

A prepaid SIM can be a flexible option because you do not necessarily have to commit to a long-term contract.

However, prepaid SIM cards in Germany are subject to identification requirements before activation. The German Federal Network Agency provides information about the identification process for prepaid mobile services.

2. eSIM

If your smartphone supports eSIM, you can use a digital SIM without inserting a physical card.

This can be particularly convenient for international students who want to have internet as soon as they arrive in Germany.

Another advantage is that you may be able to keep your existing physical SIM in your phone while using the eSIM for mobile data, depending on your device's Dual SIM capabilities.

3. Wi-Fi

Universities, student accommodation, apartments, cafés and other public places may provide Wi-Fi.

However, relying only on Wi-Fi is not always convenient.

When you are travelling around the city, using public transport or looking for an address, having mobile data gives you internet access wherever your network is available.

How Much Data Does a Student Need in Germany?

The amount of data you need depends on how you use your phone and how often you have access to Wi-Fi.

5–10 GB

This may be enough if you mainly use:

• WhatsApp and messaging

• Email

• Google Maps

• Online banking

• Websites and basic online services

If you have reliable Wi-Fi at your university and accommodation, 5–10 GB may be enough for lighter use.

15–30 GB

This is a more comfortable option for students who use mobile internet every day.

You may use your data for:

• Maps and navigation

• Social media

• Music streaming

• University platforms

• Video calls

• Messaging apps

• Browsing

30 GB or More

You may need more data if you frequently use:

• YouTube

• TikTok

• Instagram video

• Video calls

• Streaming services

• Mobile hotspot for your laptop or tablet

If you regularly use your phone as a hotspot, your data consumption can increase significantly.

As a general guide: if you have Wi-Fi at your accommodation and university, 10–20 GB may be enough. If you rely more heavily on mobile data, 20–30 GB or more can be a better choice.

SIM or eSIM: Which Is Better for Students?

Both options have their advantages.

If you are planning to live in Germany long-term, a local German number may eventually be useful.

However, if your priority is simply to have working internet as soon as you arrive, an eSIM can be a convenient solution.

Do You Need a German Address to Get a SIM Card?

This depends on the provider and the type of plan you choose.

Some local contracts may involve additional registration requirements and personal information.

For students who have not yet arrived in Germany and simply want mobile internet for their first days, preparing an eSIM in advance can be an easier option.

Which Mobile Network Is Best in Germany?

Germany has several major mobile networks, and network quality can vary depending on the city and exact location.

The German Federal Network Agency provides a mobile coverage monitoring map where users can check mobile network coverage, including 2G, 4G and 5G availability.

For this reason, it is better not to choose a network based only on its name. If you already know where you will be studying or living, checking coverage in that specific area is a good idea.

What Should You Do Before Leaving for Germany?

If you are moving to Germany as a student, you can prepare your mobile internet before your trip.

1. Check if your phone supports eSIM

Not every smartphone supports eSIM, so check your exact model before purchasing an eSIM.

2. Choose the right amount of data

Think about how much time you will spend on Wi-Fi and how often you will use mobile data outside your accommodation and university.

3. Prepare your eSIM before travelling

If you choose an eSIM, you can install or prepare it while you still have a reliable Wi-Fi connection.

4. Activate your mobile data when you arrive

Once you arrive in Germany, select the eSIM as your mobile data line according to the instructions provided with your plan.

5. Be careful with roaming on your home SIM

If you keep your Georgian or other home-country SIM active, check your data roaming settings to avoid unexpected roaming charges.
