Mobile internet in Germany for tourists: eSIM, SIM card or Wi-Fi
How to stay connected in Germany: why signal drops on trains and in the countryside, why an eSIM beats a local SIM card for most visitors, and when a Europe plan makes more sense.

The easiest way for a tourist to get mobile internet in Germany is a travel eSIM installed at home before the trip. In big cities data is usually fast, but on a train between them, or in a village on a wine route, the signal can vanish for half an hour. By law, a local SIM card in Germany is only activated after an ID check, so for a vacation an eSIM is simpler.
What’s mobile internet like in Germany for tourists?
In Germany’s big cities mobile data is usually stable, but outside them coverage is noticeably weaker than many travelers expect. Berlin, Munich, Hamburg and other big cities have 4G and in places 5G. But once you leave town, you hit dead zones: stretches with no signal, or a signal so weak that even a map won’t load.
Dead zones in Germany aren’t a glitch with one carrier or one plan. That’s simply how the network is built in some regions: in rural areas, mountains, forests and valleys there are fewer cell towers, and coverage is noticeably weaker. Treat it as a feature of the country and set up your phone to cope offline.
Why does signal drop on German trains and in the countryside?
Signal drops on trains because of tunnels, forests and hills, and the metal body of the car blocks it further. It’s tourists’ number one complaint: even on high-speed intercity trains, data can come and go. Commuter and regional trains are much the same.
According to Deutsche Bahn, as of October 2026 free Wi-Fi is available on all ICE trains, some Intercity trains and selected regional trains. But onboard Wi-Fi gets its connection from the same towers along the track, so it slows down in the same gaps as your phone. Wi-Fi in cafés, museums and small hotels is similar: fast in some places, requiring sign-up in others, cutting out after an hour elsewhere.
The good news is that the gaps are usually short. As soon as the train pulls into a station or reaches a town, your phone finds the network again, and messages sent in the dead zone go out on their own. Just don’t count on streaming video or holding a video call without drop-outs while you’re moving.
eSIM or local SIM card in Germany?
For a vacation, an eSIM is simpler: by law, a local SIM card in Germany is only activated after an ID check. The number is registered to a named person, and you verify your identity in a store with your passport, by video call or at a Deutsche Post branch. Travelers report that video ID doesn’t always accept foreign passports, and the process depends on the carrier and the store, so check on the spot.
| Option | What you need | Best for |
|---|---|---|
| MoreSim eSIM | A phone that supports eSIM | Data right after landing, no lines or registration |
| Local SIM | ID verification and a SIM slot | Long stays, when you need a German number |
| Hotel and café Wi-Fi | A password or network sign-up | Heavy downloads in the evening, not navigation |
| Home carrier roaming | Roaming switched on | A fallback; check the terms with your carrier |
An eSIM sorts out your connection before you even fly. You buy a plan on the MoreSim website or in the @moresim_bot bot, and the QR code arrives in the chat in about 30 seconds. The plan starts counting on first connection to a network in your destination, so you can install it at home a few days before the trip.
Roaming with your home carrier is also an option, but the terms depend on your plan and change, and mobile data while roaming is often expensive. Check the terms in advance, and don’t switch roaming on just in case.
Which plan should you pick: Germany or Europe?
If you’re only visiting Germany, get a Germany plan: the data and validity on offer are on the country’s catalog page. Pick a validity at least as long as your trip and size the data by your habits: a week of maps and messaging typically fits into 3–5 GB, while video and stories use a lot more.
- For a layover or a short business trip, look at the shortest plans on the Germany catalog page.
- For a long stay, study or work, take the longest-validity plan and top it up in the bot.
- Speed depends on local network coverage; in dead zones, only offline mode will save you.
- MoreSim plans are mobile data only, with no phone number. You call over messaging apps, and bank texts arrive on your home SIM.
If your route crosses several countries, look at the Europe plan: as of October 2026, it lists 47 countries, including Germany, Italy, Spain, Greece and Montenegro. It’s handy if you’re also stopping in Austria, Czechia or the Netherlands: one eSIM for the whole trip, and no switching plans at every border. Check the exact country list on the plan page before buying.
How to get online in Germany on arrival day
Getting online in Germany on arrival day is easiest if you buy and install the eSIM at home. After landing, all that’s left is switching on the line and data roaming.
- Check in the @moresim_bot bot whether your phone supports eSIM. It depends on the model and OS version.
- Buy a plan on the website or in the bot. Pay with Telegram Stars from any country, right in the bot; bank card and SBP payments currently work with cards issued in Russia.
- Install the eSIM from the QR code at home while you’re on stable Wi-Fi.
- After landing, turn off airplane mode and wait for the phone to find a network.
- Select the eSIM for cellular data and turn on data roaming for it: most travel eSIMs run on a local carrier’s network as roaming. Menu names vary by phone.
- If there’s no signal, toggle airplane mode or restart the phone.
From there it’s just like home: directions to the hotel, train tickets in the app, a message to family. If you have long journeys planned, estimate your data in advance: navigation and messaging use little, while video and stories eat through data much faster. Heavy downloads are best left for hotel Wi-Fi in the evening.
What else to know about staying connected in Germany
Your home SIM stays in the phone as a second line in Germany, and verification texts from your bank and other services reach it as long as your carrier supports roaming. Turn off mobile data on your home SIM so your data doesn’t go through your home carrier, and keep the line itself on.
- If you share data with a laptop, turn off its system updates: they burn through data fast.
- Download offline maps not just for cities, but for everywhere you’ll go by train or car.
- Turn off automatic app updates and photo backup over cellular.
- Top up with “Top up data” on the eSIM card in your account or in the bot’s app, if top-ups are available for that plan, before you run out rather than when you’re already on the road.
If something doesn’t connect, MoreSim support is reachable via /support in the bot, a ticket in your account and email.
If your data drops on a train or in the countryside, don’t rush to change settings: most of the time you’re just in a stretch with no coverage. Wait for the next station. If there’s no signal in town either, check that the eSIM is selected for cellular data and that data roaming is on for it.
FAQ
Which eSIM should I get for a week in Germany?
A week in German cities with maps, messaging and photos typically uses 3–5 GB if you save video for Wi-Fi. The data and validity of Germany plans are on the country’s catalog page; pick a validity at least as long as your trip. The plan starts counting on first connection in Germany, so you can install the eSIM at home, and if your data runs out early, you top up in the bot without a new eSIM.
Do tourists need a SIM card in Germany?
For a vacation, usually not. By law, local SIM cards in Germany are registered to a named person and only activated after an ID check, which isn’t always quick for a tourist. A German number is useful for long stays, renting an apartment or working. For data, it’s easier to install an eSIM at home: it kicks in once your phone picks up a German network after landing.
Why is mobile internet so bad on German trains?
Travelers often complain about dropped signal on German trains, including long-distance ones: the line runs through forests, hills and tunnels, and train cars block signal. This is down to the routes, not to any particular plan, and every carrier drops out on those stretches. Download offline maps, tickets and files ahead of time, and treat onboard Wi-Fi as a backup.
Does my home carrier’s roaming work in Germany?
It depends on your carrier and plan, and the terms change from time to time, so check before you fly. Mobile data while roaming is often much pricier than a travel data plan. A handy setup: turn off mobile data on your home SIM, keep the line on for verification texts, and run your data through a travel eSIM as a second line.
How do I buy an eSIM for Germany online?
You can buy a Germany or Europe plan on the MoreSim website or in the @moresim_bot Telegram bot, paying with Telegram Stars from any country, right in the bot (bank card and SBP payments currently work with cards issued in Russia). The QR code arrives in the chat in about 30 seconds. Before buying, check in the bot whether your phone supports eSIM: it depends on the model and the market it was made for.
