Germany eSIM FAQ for UK Travellers

Do I get a phone number with the eSIM?

No. Our eSIMs are data-only, so they do not come with a phone number. You use them for internet access — maps, WhatsApp, email, social media, streaming and any other app. Your existing SIM keeps your own phone number active.

Can I make or receive calls and text messages (SMS)?

Not standard calls or SMS — the eSIM provides mobile data only. You can call and message as much as you like through internet apps such as WhatsApp, FaceTime, Telegram, Signal or Messenger, which run on the eSIM's data. Standard calls and SMS keep working on your usual number through your home operator, as long as you keep that SIM active.

How much data do I need in Germany?

Many of our German customers on a 10 GB plan use all of it. If you will stream or video-call on a trip of more than a week, take 10 GB or more, or an unlimited day pass; for maps and messaging on a short visit, 3 or 5 GB is enough. Plans go from 3 GB for 15 days to 50 GB for 30 days, and unlimited day passes from 1 to 30 days, with fair use.

What network speeds will I get in Germany?

In towns and along main routes you should usually have 4G or better, on whichever of the three networks your phone picks. In rural areas, signal varies by network.

Can I share data with my laptop or tablet?

Yes, but only for Data Plans with a fixed data allowance. Unlimited plans do not support hotspot or tethering.

When should I install my Germany eSIM?

Install your eSIM while you still have WiFi at home - it is safe to do so days in advance for either plan type. Per-GB plans only start when the eSIM first connects to a network in Germany. Unlimited plans run on the travel dates you select at checkout, with the days counting from your chosen start date whether the eSIM is installed or not - so make sure it is on your phone by that date.
