What is an eSIM, and how does it work in Germany?
An eSIM (embedded SIM) is a digital SIM card built into your phone, tablet, or laptop. Instead of slotting in a physical card, you download a network profile from a provider, which connects you to a local mobile network. For Germany, that means you can buy a plan at home, install it in minutes, and arrive already online.
When you buy an eSIM plan the provider sends a QR code or an in-app install link. Scanning it loads the profile onto your device, and from then on the eSIM behaves just like a normal SIM for data. You can keep your usual SIM active at the same time, so your home number still works for calls and texts.
eSIM versus a prepaid SIM card in Germany
Germany sells prepaid SIM cards in supermarkets and phone shops, but they now require in-person ID registration, which can be slow and confusing in a new country. A prepaid travel eSIM avoids the queues and paperwork entirely. You buy online, install before you fly, and connect the moment you land, while keeping your home number active for calls and verification codes.
Mobile networks and coverage in Germany
Germany's three main mobile networks are Telekom (Deutsche Telekom), Vodafone Germany, and O2 (Telefonica). All three provide strong 4G and widespread 5G across Berlin, Munich, Frankfurt, Hamburg, and Cologne, with good coverage along the motorways and rail routes. Travel eSIMs connect through these local networks, so you get the same everyday coverage as a German SIM.
Ubigi connects to the German networks for fast, steady data across the cities and beyond, while Holafly runs on the same local infrastructure with unlimited data plans. Coverage is excellent in the cities and along the main travel corridors, and remains good in smaller towns, though signal can dip in remote forest and mountain areas like the Black Forest and the Alps.

How to choose the right eSIM for Germany
A few quick checks make it easy to pick the right plan before you travel:
Check your data needs: For maps, messaging, and browsing a small plan is usually enough. For video calls, remote work, or streaming, choose a larger plan or unlimited data.
Match your trip length: Short city breaks suit small one-off bundles, while longer stays or remote work are better with bigger plans or unlimited data.
Verify device compatibility: Most recent iPhones, Google Pixels, and Samsung Galaxy phones support eSIM. Check under Settings, then Mobile Network, then Add eSIM.
Look at support: If you want help on hand, pick a provider with a clear setup guide and live chat.
Customer support and setup help
Both providers offer support to get you online quickly. Ubigi has an in-app help centre and email support, plus clear install guides for iOS and Android. Holafly offers 24/7 multilingual chat support and a step-by-step setup flow, which is reassuring if it is your first time using an eSIM. Whichever you choose, install and test the eSIM before you fly so you land already connected.
How to set up your eSIM in Germany
Setting up your eSIM for Germany takes just a few minutes:
1. Check compatibility: Confirm your phone supports eSIM (most recent models do). Ubigi and Holafly both list supported devices on their sites.
2. Choose your plan: Pick a data size and validity that matches your trip.
3. Install the eSIM: After purchase you receive a QR code or in-app link. Scan or tap to load the profile onto your device.
4. Activate on arrival: Turn on your eSIM line and enable data roaming when you land in Germany. Activation usually starts automatically.
5. Test your connection: Open a map or browser to confirm data is working. If not, restart your phone or toggle airplane mode.
