1&1 eSIM in Germany: activation, coverage and travel options

If you are travelling to Germany, the right mobile connection depends on what you need from it. A 1&1 eSIM is a digital SIM profile for a 1&1 mobile service. It is not automatically a short-term tourist data package. Before ordering, check whether the operator’s service is available to you, how activation works for your account and device, and what network access is available at your destinations.

This guide focuses on 1&1 in the German market. It explains the operator’s eSIM process, the checks a visitor should make, and how a local mobile subscription differs from a travel eSIM. It does not list or compare individual plans. The operator’s current information was reviewed on 17 October 2026; confirm live conditions with 1&1 before applying.

Does 1&1 offer eSIM in Germany?

Yes. 1&1’s official mobile eSIM page describes eSIM as an option for its mobile service. It says customers can choose a digital SIM when ordering a new service and manage an eSIM profile through the 1&1 Control-Center. The 1&1 Help Center also explains changing an existing SIM to eSIM and activating a profile through the Control-Center app. An activation code may be offered for scanning, depending on the order and device flow.

The eSIM is the format of the SIM profile; it does not itself define the type of subscription. 1&1 also presents prepaid mobile services in Germany, but whether eSIM is available for a particular prepaid option should be confirmed in its current order flow. eSIM availability does not mean that every visitor can open an account or that the service is travel-only. New customers should check identity and eligibility steps and ask 1&1 whether their situation and documents are accepted.

1&1 is a mobile network operator in Germany and is developing its own mobile infrastructure. Its network information describes 5G availability and national roaming in areas where its own network is not yet available. As a result, the network access for a 1&1 customer can depend on location and applicable service arrangements. Use the operator’s coverage checker for specific places rather than assuming that one description applies equally to every town, railway line or building.

For an existing 1&1 customer, eSIM can be a way to use a compatible device without inserting a physical SIM. Someone who only needs mobile data during a visit should separately consider whether a local operator subscription is practical and whether a travel eSIM better fits the trip. These are different services with different eligibility, activation and support conditions.

What the 1&1 activation process involves

According to 1&1’s eSIM and Help Center pages, a customer can retrieve or activate the profile through the Control-Center app or online account. The operator may also provide an activation code to scan. For some orders that include a new phone, 1&1 says the eSIM profile can be linked to the device before it is delivered, so the customer can confirm setup when first starting the handset. The exact screens depend on the account, order and device, and can change over time.

A 1&1 product announcement about digital eSIM provisioning, checked on 17 October 2026, describes the profile being made available after the order and identity-verification steps. Treat this as a general outline, not a guarantee that every application is completed the same way or at the same speed. Follow the current instructions in your own account and contact 1&1 if the order flow asks for information you do not have.

A typical setup has these stages:

1. Complete the order or account checks. Follow any identity verification and email confirmation requested by 1&1.
2. Check the phone. Confirm eSIM support, software compatibility and that the device is not restricted by another provider.
3. Connect to Wi-Fi. Keep a stable internet connection while the profile is downloaded.
4. Open the Control-Center. Sign in to the account associated with the mobile service and choose the eSIM or SIM management option shown.
5. Install the profile. Use in-app activation where available, or scan the activation code if one is provided for that order.
6. Set your preferred lines. On a dual-SIM phone, choose which line handles mobile data, calls and messages.
7. Check registration. Wait for the device to connect, then test the service you intend to use.

On iPhone, mobile plan settings are generally found in Settings under the mobile service or cellular section. Android menu names vary by manufacturer and software version. Use current device-maker instructions alongside the 1&1 steps. Avoid deleting an eSIM profile during troubleshooting unless 1&1 advises you to: a removed profile may require a replacement process rather than a simple re-download.

If setup fails, check the internet connection and confirm you are signed into the correct account. Make sure the activation information has not already been used on another device. If you see an invalid or previously used code message, contact 1&1 through its official support channel instead of retrying repeatedly. Keep the device model, operating-system version and error details available.

Can a traveller sign up for 1&1?

The public eSIM information confirms that 1&1 offers eSIM, but it does not establish that every tourist can apply for service. A traveller who already has an 1&1 account can check the options available for that line. A new applicant should review the current application requirements and ask the operator whether the applicant’s identity documents, billing details and circumstances are accepted. Do not assume that a foreign passport, temporary stay, overseas address or a particular payment method will qualify unless 1&1 confirms it.

An eSIM profile does not bypass customer onboarding. A new service may involve account creation, identity verification or other checks before the profile can be activated. If you are arriving soon, confirm these steps in advance and leave time to complete them. If mobile data is essential as soon as you land, keep a backup way to get online in case the application or verification cannot be completed immediately.

For an existing customer replacing a physical SIM, sign in before travel and check the current SIM management process. If you are changing phones, confirm whether the profile can be transferred or whether 1&1 must issue a replacement. Do not erase the old profile or reset a working phone until you know how the transfer works and have access to the account used to manage the line.

A visitor who cannot complete a new local subscription can still use a phone that supports eSIM with a different provider, subject to that provider’s rules. A travel eSIM may be an option for mobile data in Germany; its coverage, supported networks, calling features and setup rules should be checked separately. Availability of eSIM technology on the handset and eligibility for a particular operator service are two different questions.

Device compatibility and regional variants

A handset can support eSIM in one sales region but not in another. Phones with similar marketing names may have different hardware, SIM configurations, supported frequency bands or carrier restrictions by country. Check the exact model identifier and regional variant rather than relying only on the family name printed on the device.

Before choosing an operator or travel eSIM, confirm that the phone has eSIM capability in its country-of-sale variant, that its operating system supports adding a mobile profile, and that it is not carrier-locked. Then check that the provider supports the device and the service you intend to use. A device can be technically capable of storing an eSIM while still lacking compatibility with a particular network feature.

Some devices show an eID in settings or device information, which can help identify eSIM capability. Menu paths differ, so manufacturer specifications for the exact model should be treated as the reference. If your phone was purchased outside Germany, do not infer compatibility from a similarly named model sold in Germany. The regional modifier is part of the device identity.

If you use a physical home SIM and a second eSIM together, check which combinations can remain active on your phone. Verify how the device assigns mobile data, calls and SMS, and whether the home provider charges for roaming. For a travel eSIM, see Kaspersky eSIM Store device compatibility; then confirm service compatibility with the provider as a separate step.

Coverage and network technology

1&1’s coverage checker and network pages were reviewed on 17 October 2026. The operator describes its own developing mobile network and national roaming for areas where its own coverage is not yet available. Its public network information discusses 5G and LTE (4G), but actual availability depends on the location, device and service. Network use can change as a customer moves between areas.

Check the map for the addresses, cities and transport routes relevant to your trip. Coverage estimates cannot guarantee a signal inside a hotel, station, underground area or train. Buildings, terrain, congestion, maintenance and device capabilities can affect the connection. Treat map information as a planning aid, not a promise of a particular speed or uninterrupted service.

For a travel eSIM, coverage depends on that service’s local network arrangements and product scope. Verify Germany coverage and any cross-border destinations you need. A Germany selection does not automatically include neighbouring countries, and a country-level label does not guarantee the same experience in every location. Check current service information before buying or activating.

Local operator eSIM or travel eSIM?

A local operator eSIM and a travel eSIM use the same digital SIM technology but serve different needs. A 1&1 eSIM is a digital profile for a 1&1 mobile service in the German market. It may suit someone who already has a 1&1 account or can complete the operator’s current application and wants a local mobile service. A travel eSIM is arranged for use away from a home mobile service and is often intended for mobile data during a trip. Its enrolment, coverage and included functions depend on the specific provider and product.

Neither option is automatically right for every traveller. Consider how long you will stay, whether you need a German phone number, whether ordinary calls and SMS matter, whether you can meet local customer onboarding requirements, and whether your phone can run two lines in the way you need.

• Investigate a local subscription if you need continuing service, already have a 1&1 account, or can complete the operator’s application and verification process.
• Check a travel eSIM if the main need is mobile data for a visit and you want a separate connection for the destination.
• Keep your home line in mind if you rely on your usual number for calls or verification codes. Confirm roaming conditions with your home provider.
• Compare service scope. Check whether mobile data, calls, SMS, tethering and support are available on the exact service you are considering.
• Check compatibility twice. Confirm the phone’s regional variant supports eSIM and that the provider supports that device and service.

Some travel eSIMs are data-only and do not include an ordinary number, voice calls or SMS. Other products may differ. If your home SIM stays active while a travel eSIM handles data, incoming calls and messages depend on your home plan, phone settings and roaming conditions. Confirm these details before relying on them.

Kaspersky eSIM Store is an app and website where travellers can choose, purchase and activate an eSIM with a plan for mobile internet abroad. It can be considered when you want to prepare a separate data connection for a trip. Kaspersky eSIM Store is not a mobile network operator, network owner or direct provider of mobile internet coverage. Check current destination availability, compatibility and service conditions before choosing an eSIM.

If Germany is your destination, you can view Germany eSIM options in Kaspersky eSIM Store. Check that the chosen option covers the places on your itinerary and install it using the instructions supplied for your device. If your route crosses a border, verify each country rather than assuming that a Germany-only selection extends beyond it.

Frequently asked questions

Does 1&1 offer eSIM in Germany?

Yes. 1&1’s current mobile eSIM page and Help Center describe eSIM for its mobile service, including digital profile management through the Control-Center. The available setup route depends on the account and order.

Can a tourist buy a 1&1 eSIM on arrival?

The public information confirms eSIM support but does not show that every tourist can sign up. Check current application and identity-verification requirements with 1&1, including whether your documents and circumstances are accepted. Keep a backup way to connect if you need data immediately.

Is a 1&1 eSIM the same as a Germany travel eSIM?

No. A 1&1 eSIM is the digital SIM format for a 1&1 mobile service. A travel eSIM is a separate service for travel connectivity, with its own coverage, eligibility and activation conditions.

How do I activate a 1&1 eSIM?

Use the Control-Center app or online Control-Center and follow the instructions for your account. Scan an activation code if one is provided. Keep the phone online during setup and use current device instructions.

Will an eSIM work on every phone?

No. The exact model and regional variant must support eSIM, and the phone must be compatible with the service. Check the carrier-lock status and provider guidance before ordering.

Is 1&1 coverage uniform throughout Germany?

No. Availability varies by location and can change as the network develops. 1&1 describes its own network and national roaming where its own coverage is not available. Check current location information and remember that indoor and transport coverage can differ from map estimates.

Can I keep my usual number while using a travel eSIM?

A dual-SIM phone may allow more than one line to be configured, but the available combinations depend on the handset and home plan. A data-only travel eSIM may not include calls, a regular number or SMS. Confirm how your lines work before travelling.

Is Kaspersky eSIM Store a German mobile operator?

No. It is an app and website that helps users choose, purchase and activate an eSIM plan for mobile internet abroad. It does not own a network or directly provide mobile coverage.

A practical way to choose

Start with the service you need. If you already use 1&1 or can meet its current application requirements and want a local mobile service, check the operator’s activation route and coverage at your destinations. If you mainly need mobile data for a visit, evaluate a travel eSIM separately and verify its Germany coverage, activation timing, device compatibility and included functions.

Install your chosen profile while connected to reliable Wi-Fi, check which line is set for mobile data, and keep essential travel information available offline. For account or activation questions, use the current 1&1 Help Center and customer support. For a travel eSIM, follow that service’s own instructions and conditions. Eligibility, network access and support arrangements are not interchangeable between the two types of service.

The name 1&1 and related marks belong to their respective rights holders. Kaspersky eSIM Store is independent and is not affiliated with, endorsed by or an official partner or distributor of 1&1. Information was checked on 17 October 2026 against 1&1’s eSIM page, Help Center, digital provisioning announcement, prepaid product information and network coverage checker. Review the operator’s current public information before ordering because service details can change.
