Using an eSIM in Hamburg

What Hamburg is like on a phone

Hamburg is a port city people come to for the water: the enormous harbour, the canals through the old warehouse district, and the lake in the middle of town with dinghies on it. The visitors tend to be families who like a waterside walk, concert-goers, and travellers heading on to Scandinavia. The city is spread out but stitched together by several rail systems, and above ground the network is evenly usable. What sets it apart is having both a tunnel under the river and public ferries, which change the signal in ways a land train never does.

À l'atterrissage

Hamburg Airport (HAM) has a suburban station attached to the terminal, under half an hour from the centre, while trains from Berlin, Copenhagen or elsewhere arrive under the curved iron roof of the Hauptbahnhof. Switch the line on inside the terminal, because you need a ticket covering the airport zone and the machines come before the platform. The ride in keeps service since almost the whole route is above ground, then falls away inside the station hall, with its steel frame and its crowds.

Où la couverture change

The harbour front, the city lake and the residential districts stay connected. In the red-brick warehouse quarter built across the canals, tall blocks flank narrow walkways and the signal weakens as you get in among them. The old tunnel under the river and the underground passages at some stations stay quiet until you surface on the other side. The harbour ferries do keep service, being close to both banks, though the wind and spray mean most people put the phone away rather than use it.

What a day here costs in data

A day along the water runs about 700MB to 1.1GB, since you are outdoors and the map goes on and off. Take a harbour ferry and film the container ships for minutes at a time and the number climbs far faster than stills ever do. Concert-goers at the waterfront hall use more in the window before and after a performance, when everyone uploads at once. If you work during the trip, count meeting hours separately — that is the part that dominates.

Districts travellers ask about

• Speicherstadt and HafenCity — The narrow ways between the brick warehouses take the signal down; step out onto the open quays of the newer quarter and it returns at once.
• St. Pauli and the Landungsbrücken — The quayside is open and works well, but on a packed weekend night the whole street is busy enough that ride-hailing and video uploads lag for a while.
• The Alster lakes — The paths around the lake are open and steady — a good place to take a call on the move or clear a photo backlog from a bench.
• Altona and the Elbe bank — The western riverside path is good the whole way, though the stairs and ramps down to the sandy shore weaken once you are below the bank.

Day trips out of the city

• Lübeck — A short train with service all the way; the moated old town, with its narrow cobbled streets, slows a little as you walk between the tall brick houses.
• The North Sea coast and the islands — On shore you keep service, but the crossing to an island breaks up because the masts are all on land — download the ferry ticket and return timetable before leaving the quay.
• Bremen — The line crosses open flatland with near-continuous service, and in Bremen the central square is wide enough to stay comfortable even on a market day.
