About this eSIM

Most of a German trip turns out to be a timing problem. A connection to catch at Frankfurt, a platform change announced while the train is still moving, a ticket that has to load in an app before the conductor reaches your row. An eSIM added before departure gives you the information layer that all of it assumes you have, live from the moment you land at Frankfurt, Munich, Berlin Brandenburg, Düsseldorf or Hamburg, with no roaming charge waiting for you at the end of the month.

Getting online when you land

Get the eSIM onto the phone before you leave the house. The install itself needs a connection; after that the profile just sits there until you activate it, so there is no reason to leave it to the airport.

When you arrive, two things have to be true: the travel line switched on, and roaming permitted on that line. The second one is where most first-time eSIM problems live. Without it the profile cannot attach to a German host network, and the symptom looks like a dead SIM rather than a settings issue.

Do this before you go down to the S-Bahn. Frankfurt and Munich both put their railway stations underneath the terminals, and the moment you are on a platform is the moment you want the departure app, not the moment to be reading a setup guide.

Your home line stays in place with its data off, keeping your number live for calls and one-time codes.

The networks you'll be on

German service here runs through O2 and Vodafone. Both carry 4G/LTE and 5G, which in practice means 5G across the major cities and 4G/LTE almost everywhere else that people live and drive.

Selection is automatic and continuous. The phone re-checks as you travel and will switch operator without asking, so the name in the status bar changing between Berlin and Munich is not a problem to solve. Leave it on automatic and it will make better decisions than you can, faster.

Where coverage holds, and where it thins

Urban Germany is dependable: Berlin, Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf, Leipzig, Dresden, Nuremberg and the whole Ruhr conurbation. The autobahn network holds a connection between them, which matters if you are driving and using live traffic to decide whether to sit in a Stau or come off at the next exit.

Trains are where it wobbles. High-speed lines run through long tunnels, particularly on the Cologne to Frankfurt route, and the Munich and Frankfurt S-Bahn trunk tunnels cut you off completely for a few stops. Nothing about that is a fault; it is just a reason to load your seat reservation and your connection details before you board rather than while standing in the vestibule.

Rural gaps are real and they are not always where you expect. Valleys in the Black Forest, the Bavarian Alps once you leave the valley floor, the Harz, the gorges of Saxon Switzerland, the Eifel, and thinly populated stretches of Brandenburg and Mecklenburg all have patches where the signal simply is not there. Long-distance cycle routes along the rivers are better than the hills but still uneven.

What you'll actually use data for here

The DB Navigator app, more than any other single thing. German trains change platform, run late, get cancelled and swap connections, and the app is where that information surfaces first, in real time, along with which carriage section your reserved seat is in. If you are travelling on a Deutschlandticket, that is a pass on your phone, which means it needs to open when a conductor asks and not five minutes after.

Cities each have their own transport app, BVG in Berlin and MVG in Munich among them, and they are worth installing on arrival for live U-Bahn and tram disruption. Ride-hailing apps fill the late-night gap where the network is thinner.

Then there is the German cash question, which never fully goes away. Plenty of bakeries, kiosks, market stalls and small restaurants are cash only, and a surprising number of otherwise modern places will not take a foreign card, so looking up whether somewhere takes cards, or finding the nearest bank machine, is a genuine daily use. Add timed-entry tickets for the popular castles and museums, opening hours that shut down hard on Sundays, and translation for the small print on a ticket machine, and the data adds up quietly.

Before you fly

Install and name the profile at home; confirm the handset is unlocked and eSIM capable.
Put your rail bookings, seat reservations and any travel pass in the phone wallet or the DB app before you leave.
Pull down offline maps for anywhere alpine or forested on the itinerary.
Note that Sunday closing is near-total outside stations, so plan supplies with data while you have it.
Leave the home line active for verification codes with its data disabled.
Make the travel line the default for mobile data.

Unlimited runs at full speed up to a fair-use limit, then continues slower.

Before you buy

Important to know

This is a data-only eSIM. It carries no calls or SMS on its own number.
Your existing number stays on your primary SIM, so calls and verification texts keep working.
Your phone must support eSIM, and some carrier-locked phones cannot install one.
Signal varies with location, terrain, congestion and your handset. Dense urban areas are consistently better served than remote ones.
5G only works where the host network has deployed it and your phone supports it. Everywhere else it falls back to 4G LTE.
The eSIM selects a host network automatically. You cannot pick or switch between them.
Unlimited plans run at full speed up to a fair-use limit, then continue at a reduced speed. Read the fair usage policy

Frequently asked questions

Does an eSIM work in Germany?

Yes. Your Germany eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are O2, Vodafone. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere.

Do I get 5G in Germany?

Yes, where it has been deployed. 5G runs on O2, Vodafone in Germany, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location.

Can I use the Deutschlandticket on ICE trains?

No. The Deutschlandticket covers local and regional transport nationwide, including S-Bahn, U-Bahn, trams, buses and regional RE and RB trains, in second class only. It is not valid on ICE, IC or EC long-distance trains or long-distance coaches such as Flixbus, apart from a few subsidised exceptions. It costs €63 a month from January 2026.

Is the Deutschlandticket worth it for a short visit to Germany?

It can be, but check the rules. It is a monthly subscription that renews automatically; you can cancel up to the 10th of the month, and if you join after the 10th you pay for two months. It is digital only, so it lives on your phone, and a credit card is easier than SEPA debit without a eurozone bank account.

Is there still 3G in Germany?

Not on O2, which phased out 3G by the end of 2021 and reused the spectrum for 4G. Germany's mobile data now runs on 4G and 5G; O2 reports 5G coverage for about 99% of the population. Older guides that list 3G as a fallback are out of date, so where 4G and 5G fail, expect no data.

Is wifi free at Munich Airport?

Yes. Connect to the network called "Free Wifi – Munich Airport", enter your email address and accept the terms. The airport suggests the Passngr app for automatic login on later visits. It is handy for downloading apps or offline maps at baggage reclaim, but you will need mobile data once you head for the S-Bahn.

How much data do I need for 7 days in Germany?

For 7 days in Germany, Viasimo sells 1 GB for $1.59 and unlimited data for $13.99. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone.

Know before you go

Germany: what to know before you land

In Germany your phone is your train ticket: the Deutschlandticket, now €63 a month, is digital only and covers regional trains, buses and trams nationwide but not ICE or IC services. Your eSIM uses O2 and Vodafone. O2 says its 5G reaches about 99% of the population and it switched off 3G at the end of 2021, so 4G and 5G are what you will use.

The Deutschlandticket on your phone: €63, regional only

The Deutschlandticket gives unlimited travel on local and regional public transport across Germany: S-Bahn, U-Bahn, trams, buses and regional trains (RE and RB). It cost €58 a month in 2025 and rose to €63 from January 2026.

What visitors often miss:

It is digital only. There is no paper version. It lives in a transport operator's app or a phone wallet, or on a chip card, so your phone needs to be charged and able to show the ticket during inspections.
It is not valid on ICE, IC or EC long-distance trains, or on long-distance coaches such as Flixbus, apart from a few subsidised exceptions. It is second class only.
It is a monthly subscription that renews automatically. You can cancel up to the 10th of the month. Subscribe after the 10th and you pay for the current and the next month.
Payment is by SEPA direct debit or credit card. If you do not have a eurozone bank account, a credit card is the easier route.

It is also accepted on selected cross-border services to nearby stations such as Basel, Salzburg and Tønder. For a short trip with a couple of ICE journeys, compare it against simply buying individual tickets in DB Navigator.

O2 and Vodafone: 5G nearly everywhere, 3G gone

Your eSIM connects to O2 (Telefónica Germany) and Vodafone, two of the country's three established networks alongside Deutsche Telekom.

O2 had about 35.2 million mobile connections at the end of 2025. It reports 5G for about 99% of the population and near-total coverage for LTE. It phased out 3G by the end of 2021 and reused the spectrum for 4G.
Vodafone started 5G in Germany in July 2019 and has more than 30 million mobile customers.

In practice, older guides that mention 3G as a German fallback are out of date. Where 4G and 5G are not available, you may not have usable data at all. Expect this in deep valleys and forests rather than in towns.

Population coverage figures also overstate what you will see on the move. Ninety-nine per cent of people is not 99% of land, and rural stretches of the Bavarian Forest, the Harz, the Eifel and parts of Brandenburg and Mecklenburg-Vorpommern have gaps. Long ICE tunnels and modern railway carriages, whose metallised windows block signal, also weaken reception. Download maps and tickets before you set off.

Arriving at Munich (MUC) and Frankfurt (FRA)

Germany's two biggest hubs both put their railway stations beneath or beside the terminals, so you are usually on a train within minutes of collecting your bags.

At Munich Airport, wifi is free: join "Free Wifi – Munich Airport", enter an email address and accept the terms. If you pass through regularly, the airport points to the Passngr app, which can log you in automatically on future visits. It is a useful backup for downloading apps or offline maps while you wait for luggage, but you still need mobile data once you leave the building.

For the journey from either airport:

Munich: the S1 and S8 S-Bahn lines run into the city, and both are covered by the Deutschlandticket. Long-distance trains do not run from the airport itself.
Frankfurt: the regional station serves S-Bahn trains into the city (covered by the Deutschlandticket), and the separate long-distance station serves ICE trains, which are not.

If you are connecting by train, open DB Navigator before you reach the platform. Delays and platform changes appear there first, and the S-Bahn tunnel stretches into both city centres are where signal tends to drop.

7-day itinerary

Seven days in Germany: Berlin, Potsdam, Munich and Neuschwanstein

A rail-based first visit that pairs Berlin's history and museums with Bavaria: two days in the capital, Potsdam's palaces, an ICE ride south to Munich, Neuschwanstein in the Alpine foothills and a final morning at the Dachau memorial.

Length: 7 days
Bases: 2

When to go May to September for long days and beer gardens; late November to Christmas for markets in Berlin and Munich, when days are short and cold; avoid Munich during Oktoberfest, late September to early October, unless you are going for it.

Day 1 Berlin

Berlin: the Reichstag to the Wall

From Berlin Brandenburg Airport (BER), the FEX airport express and regional trains reach the centre in about 30 minutes.

Start at the Reichstag; the glass dome is free but must be booked ahead. Walk through the Brandenburg Gate and past the Memorial to the Murdered Jews of Europe to Checkpoint Charlie and the Topography of Terror. In the afternoon, take the S-Bahn to the Berlin Wall Memorial on Bernauer Strasse, then end at the East Side Gallery's painted stretch of wall by the Spree.

Signal O2 and Vodafone 5G are strong across central Berlin. Coverage on the U-Bahn has improved but can still drop between some stations.
Day 2 Berlin

Museum Island and Prenzlauer Berg

Spend the morning on Museum Island, a UNESCO site; choose two of the Neues Museum with the bust of Nefertiti, the Altes Museum or the Bode Museum; the Pergamon Museum is closed for renovation until around 2027. Look into the Berlin Cathedral, then climb the TV Tower at Alexanderplatz or walk north to the cafes of Prenzlauer Berg and the Sunday flea market at Mauerpark if your timing fits.

Signal Strong 5G throughout Mitte. Museum galleries can weaken signal, so download audio guides at the entrance.
Day 3 Berlin

Potsdam: Sanssouci

About 25 minutes by regional train from Berlin Hauptbahnhof; the Deutschlandticket covers it.

Take a regional train to Potsdam. Walk through Sanssouci Park, part of the UNESCO-listed palaces and parks of Potsdam and Berlin, visiting Frederick the Great's Sanssouci Palace and the much larger New Palace. In the afternoon, see the Dutch Quarter's red-brick houses and the Alexandrowka Russian colony, then visit Cecilienhof, where the Potsdam Conference was held in 1945.

Signal Good 5G in Potsdam town. Signal can dip in the wooded far corners of the parks.
Day 4 Munich

ICE to Munich

Fast ICE trains take about four hours; the Deutschlandticket is not valid on ICE, so buy a separate ticket.

Take a morning ICE from Berlin to Munich. After checking in, walk from Marienplatz, where the Glockenspiel plays in the New Town Hall tower, to the Viktualienmarkt food market and up St Peter's Church tower for the view to the Alps on clear days. End the day in the Englischer Garten, watching surfers on the Eisbach wave, then at the Chinese Tower beer garden.

Signal Mobile coverage along the high-speed line has improved but still has gaps in tunnels through Thuringia and Franconia; use the onboard wifi or download content first.
Day 5 Munich

Munich: the Residenz and Nymphenburg

Tour the Munich Residenz, the former royal palace of the Wittelsbachs, including its treasury. In the afternoon, take a tram out to Nymphenburg Palace and its gardens. Alternatively, spend the afternoon at the Deutsches Museum's science and technology collections on the river island. In the evening, try a traditional beer hall in the old town.

Signal Excellent 5G across central Munich; the U-Bahn has coverage in most stations.
Day 6 Munich

Neuschwanstein and Hohenschwangau

About two hours by regional train from Munich to Füssen, covered by the Deutschlandticket, then about 10 minutes by bus.

Take an early regional train to Füssen, then a bus to Hohenschwangau. Visits to Neuschwanstein are by guided tour only, so book your timed ticket ahead. Walk or take the shuttle bus up, look out from the Marienbrücke if it is open, then tour the castle's interiors. If you have time, visit Hohenschwangau Castle or walk by the Alpsee lake before returning.

Signal Good 4G and 5G in Hohenschwangau village. Signal can be weaker on the forest paths and in the Pöllat gorge below the castle.
Day 7 Munich

Dachau memorial and departure

About 40 minutes to Dachau by S-Bahn and bus; Munich Airport is about 40 minutes from the centre by S-Bahn.

Spend the morning at the Dachau Concentration Camp Memorial Site, the first Nazi concentration camp, which you can reach by S-Bahn and bus. Allow at least three hours for the exhibition and grounds. Return to Munich and head to the airport by S-Bahn, or spend a final hour in the old town.

Signal Good 5G at the memorial site and on the S-Bahn. Munich Airport also has free wifi if you need to check in.

Staying connected on this route

Install DB Navigator before travelling; it holds both ICE tickets and the Deutschlandticket, which is digital only.
Download maps and entertainment before the Berlin to Munich ICE, which still passes through some coverage gaps.
Book the Reichstag dome and Neuschwanstein online in advance and keep the confirmations saved offline.
