Roaming in the UK can quickly become a cost trap after Brexit if you don’t prepare properly. While EU roaming is protected by legal regulations, different rules apply in the United Kingdom, which can lead to surprisingly high bills. With the right preparation and the right alternatives, however, you can stay connected affordably and avoid unpleasant surprises on your phone bill.
What is UK Roaming and why is it so expensive?
Roaming refers to the use of your German mobile contract abroad. Since the UK is no longer part of the EU, EU roaming protection laws no longer apply there. Your smartphone automatically connects to British networks such as EE, Vodafone UK, or Three, while your German provider charges high surcharges. The costs arise from complex negotiations between German and British mobile operators. These roaming agreements often result in prices many times higher than local rates. Without proper preparation, you can quickly pay between €5 and €15 per 100 megabytes of data—a cost that can be reached within just a few hours of normal smartphone use.
Why are roaming charges applied in the UK?
The EU roaming regulation only applies within Europe and protects you from overpriced rates in EU countries. In the UK, German providers negotiate individual tariffs with British network operators, which often turn out to your disadvantage. These negotiations take into account factors such as network quality, coverage, and usage volume but usually result in high costs for end consumers.
Automatic connection and hidden costs
Your phone automatically connects to the available UK network as soon as you enter British territory. Even without active use, background apps, automatic updates, or push notifications can already cause costs. Particularly tricky are email synchronization, social media updates, and messenger services, which continuously transmit small amounts of data and can silently generate high costs.
UK Roaming costs with German providers at a glance
The cost of UK roaming varies greatly between German providers. Without special data packages, you often pay between €5 and €15 per 100 MB of data. These prices add up quickly: a simple Google Maps search, sending photos via WhatsApp, or retrieving emails can already cost several euros. Most German mobile providers have recognized this issue and offer special UK packages. While these are cheaper than standard rates, they are still significantly more expensive than local alternatives. Comparing the different providers helps you find the best option for your needs.
Telekom UK roaming prices
Deutsche Telekom currently still treats the UK as an EU country and places it in Zone 1. This means you can use your German tariff services without additional costs. However, this goodwill policy is not permanently guaranteed and can be changed at any time. If revoked, standard roaming prices of €0.69 per minute for calls would apply. Data roaming could then cost up to €12 per 100 MB. Telekom already offers international options such as "Telefonie EU 30" for €1.95 per month, which also covers UK calls.
Vodafone UK roaming tariffs
Vodafone Germany continues to treat the UK as part of the EU roaming zone. The official statement is: "The UK remains part of the EU roaming zone even after Brexit. Nothing will change in the tariffs for now." However, the phrase "for now" suggests a temporary goodwill policy. The advantage is easy handling and the ability to keep your German number and all familiar services. Vodafone also offers the possibility to make calls via VoLTE, which ensures better voice quality.
O2 and other providers’ roaming costs
O2 has set a specific transition period until December 31, 2025. According to the price list: "For the UK, despite leaving the EU, charges will continue to be billed according to Zone 1 (EU-regulated) until 31.12.2025." This deadline may be extended but is not guaranteed. Other providers such as 1&1 charge up to €2.49 per minute for outgoing calls and €1.49 for incoming calls if the goodwill policy is revoked. These costs add up quickly, especially for longer calls or frequent use. Prepaid providers often have even higher rates, sometimes up to €15 per 100 megabytes.
How to enable and disable UK roaming
Configuring your smartphone correctly is crucial to avoid cost traps or to deliberately use roaming. The settings vary depending on the operating system, but the basic steps are similar on Android and iOS. Before traveling, you should check with your provider about available UK packages and, if necessary, book them. Many providers also send SMS with current tariff information as soon as you log into a foreign network.
Enable UK roaming
To activate roaming, go to your smartphone settings under "Mobile Networks" or "Connections" and enable "Data Roaming". On iPhones, you’ll find this option under "Settings" > "Mobile Data" > "Data Options". Check with your provider beforehand whether special UK packages are available and book them in advance. After activation, your smartphone automatically connects to available British networks. You usually receive a welcome SMS with tariff information and customer service contact details. Be sure to disable automatic updates to avoid unwanted data usage.
Disable UK roaming for cost protection
To deactivate roaming, go to the same settings and switch off "Data Roaming". Additionally, you can enable flight mode and use only Wi-Fi. Remember to disable automatic app updates and background app refresh. This method is particularly useful if you mainly want to use Wi-Fi or an alternative solution such as an eSIM. You remain reachable on your German number but avoid expensive data costs from unwanted connections.
Tips for saving on UK roaming
With the right strategies, you can also save money when using traditional roaming and still stay connected. These tips help you control your data usage and use affordable alternatives. The most important rule is: Preparation is everything. Find out about available options before your trip and configure your smartphone accordingly. Many cost traps can be avoided with simple setting changes.
Use Wi-Fi hotspots effectively
The UK has an excellent Wi-Fi infrastructure. Use free Wi-Fi in:
- Hotels and restaurants
- Cafés (Starbucks, Costa Coffee)
- Pubs and bars
- Airports and train stations
- Supermarkets (Tesco, ASDA)
- Libraries and museums
Always use a VPN for extra security, as public networks pose security risks. Apps like WiFi Map or Facebook’s "Find WiFi" feature can help you locate hotspots nearby.
Prepare offline functions
Download important content before your trip:
- Google Maps offline maps for your travel regions
- Spotify playlists for offline mode
- Google Translate offline packages for translations
- Important documents (hotel details, emergency contacts)
This preparation significantly reduces your data usage and makes you less dependent on a constant internet connection. Offline content is especially useful in rural areas where coverage may be weaker.
Monitor and control data usage
Check your data usage regularly in your smartphone settings. Set warnings at certain limits and disable automatic updates for apps and the operating system. Streaming services like YouTube or Netflix should only be used via Wi-Fi as they are extremely data-intensive. Use data-saving modes in your apps and reduce image quality on social media. WhatsApp and other messengers offer settings to reduce data usage. These small adjustments can significantly cut your costs.

Buying a UK SIM card locally: providers
If your smartphone does not support eSIM, you can also purchase a physical SIM card in the UK. This option requires more effort but can be cost-effective for longer stays. Buying a local SIM card means you’ll get a British phone number and will no longer be reachable on your German number. This solution is particularly suitable for longer stays or if you mainly want to use local contacts.
EE, Vodafone UK and Three prepaid tariffs
The three major UK network operators offer prepaid SIM cards in supermarkets, airports, and their own stores:
- EE: Best nationwide coverage, strong in rural areas
- Vodafone UK: Good prices in cities, high speeds
- Three: Reliable coverage and affordable data tariffs
Expect to pay £15–25 for 30 days with several gigabytes of data. The tariffs usually also include unlimited SMS and free minutes for calls within the UK. International calls cost extra but can be bypassed via apps like WhatsApp.
Tesco, ASDA and other retailers
Prepaid SIMs are not only available in mobile phone shops. Tesco, ASDA, Sainsbury’s, and other retailers offer various providers at often cheaper prices. The advantage is longer opening hours and the wide availability of these stores. Note that you need an ID and activation may take some time. Some tariffs require a UK address, which can be problematic for tourists. The language barrier can also be a challenge.
eSIMony tethering and hotspot function
With eSIMony, you can use your smartphone as a mobile Wi-Fi hotspot and provide internet to other devices. This function is particularly valuable for travelers with multiple devices or families. The hotspot function turns your smartphone into a mobile router that can provide internet to up to 10 devices at the same time. This way, you use one eSIMony connection for your laptop, tablet, and other smartphones.
Connecting multiple devices with eSIMony
The eSIMony UK eSIM supports tethering at no additional cost. You can run laptops, tablets, or other smartphones through your connection. This is especially practical for families or business travelers with multiple devices. The hotspot function is already included in the tariff and requires no extra fees. Setup is done via your smartphone’s hotspot feature. You create a Wi-Fi network with a password and connect your other devices. Speeds remain high even when tethering, as eSIMony provides access to fast UK networks.
Optimal use of the hotspot function
Keep in mind that tethering increases data usage since multiple devices are online at the same time. Therefore, choose an eSIMony package large enough for your needs. In your smartphone settings, you can limit the number of connected devices and monitor data usage. This way, you maintain control over your costs and avoid exceeding your data volume. Most modern smartphones even show consumption per connected device, making monitoring easier.
Common UK roaming problems and solutions
Despite good preparation, problems may arise with UK roaming. The most common issues can usually be solved easily if you know the right steps. Network problems, slow connections, or activation difficulties are the typical challenges. With the right troubleshooting, you can quickly and effectively handle these situations.
No network reception after arrival
Check the network settings and manually select a British provider from the available networks. Make sure your smartphone supports British frequency bands—most modern devices have no problem with this. With eSIMony, check whether the data plan is already activated and the correct eSIM is selected as the primary data carrier. Restarting the smartphone often helps with connection problems. Also check that roaming is enabled in the settings and that there are no restrictions.
Slow internet connection
eSIM tariffs can sometimes have slower connections because they use data roaming via partner networks. However, eSIMony offers direct access to premium British networks for optimal speeds. In rural areas, coverage is generally weaker than in cities, regardless of provider. Local SIM cards usually offer the best speeds as they have direct network access. For persistent issues, contact eSIMony customer service for assistance and possible solutions.
Conclusion: Travel smart with the right UK connection
Roaming in the UK doesn’t have to be expensive if you choose the right strategy. Traditional roaming without preparation quickly leads to high costs, but with the right alternatives, you can stay connected affordably. eSIMony offers the best combination of price, performance, and convenience for German travelers to the UK. Easy installation, transparent pricing, and German customer service make eSIMony the best choice for every traveler.
