SIM with eSIM profile: How to use eSIM on unsupported phones

The eSIM revolution has arrived with full force, but if your phone isn't natively compatible with this technology, all is not lost. In recent years, ingenious alternatives and adapted solutions have emerged to take advantage of the benefits of the digital SIM even in phones that don't support it out of the box. This article breaks down in detail everything you need to know about using an eSIM or a SIM with an eSIM profile in phones that don't originally support it , reviewing viable methods, compatible devices, benefits, precautions, and much more.

If you travel frequently, want more competitive rates, or are simply looking to ditch the plastic of a physical SIM, here you'll find a complete and updated guide with the safest and most recommended options. Get ready to discover a smart way to take advantage of eSIMs on devices that seemingly aren't "ready" for this technology.

What is an eSIM and how does it work?

The eSIM is the evolution of the classic physical SIM card . Instead of being manually inserted into a slot, the eSIM is integrated into the device's hardware : a chip soldered to the motherboard that allows for the remote installation of different carrier profiles. The name comes from the English phrase "Embedded Subscriber Identity Module . "

Its basic function is the same as a traditional SIM: it allows you to connect to a carrier's network, make calls, send messages, and browse the internet . The essential difference lies in its flexibility : you can install multiple profiles from different companies and switch between them very easily, without having to remove or insert any physical card.

In practice, eSIM activation is usually done using a QR code provided by the operator after contracting, although some processes allow it to be done with their own apps or even with direct activation if the operator and the device support it.

In addition, you can have several eSIMs stored and choose which one to use at any given time, which is especially useful for travelers or those who manage multiple numbers.

Why look for an eSIM on incompatible phones?

The use of eSIMs is growing for several reasons. They offer flexibility, convenience, and more digital management of mobile lines . However, most manufacturers only integrate this feature into high-end or recent models, such as iPhones from the XR/XS onward or premium Androids (Samsung Galaxy S, Google Pixel, some Xiaomi and Huawei phones , among others).

But why would anyone want to use an eSIM on an unsupported phone?

• International travel: Ordering eSIM data profiles from foreign operators is easier and faster than purchasing physical SIMs.
• Economic savings: Many eSIM plans, especially for travelers, are more affordable.
• Detachment from the physical SIM: Never lose your card again or wait for it to arrive in the mail.
• Avoid roaming: You install a local profile and browse at the best price.

The demand for using eSIMs on "non-compatible" phones is real . Fortunately, solutions and adapters have emerged to enable eSIM profiles even on devices that don't support them out of the box.

What is an eSIM profile? Magic happens with eUICCs.

The key to all of this lies in the technical specification. A traditional SIM is based on the UICC ( Universal Integrated Circuit Card ) standard, while the eSIM or virtual SIM uses the eUICC (integrated UICC) variant, which allows for remote installation of operator profiles.

Here's the trick: nothing prevents the manufacture of physical SIM cards with the eUICC specification . These are normal SIMs that fit in any phone's slot, but internally they support eSIM profile management, just like an integrated eSIM.

There are already several international companies on the market such as eSIM.me , 5ber or JMP that market these products: SIM cards compatible with eSIM profiles that work in phones that only support physical SIMs.

These cards allow you to install eSIM profiles from carriers anywhere in the world , provided your phone is compatible with a specific management system (there are nuances we'll discuss later). Prices typically range from €25 to €35 for the SIM adapter itself, plus the cost of the eSIM profile you want to install.

How do SIM adapters with eSIM profile work?

The process is simple, although it requires following some steps:

1. Purchase a SIM card with an eSIM profile (from eSIM.me, JMP, 5ber, etc.).
2. Insert it into your phone's standard SIM slot.
3. In most cases, you will need to use one specific application (provider app) to manage the installation and activation of eSIM profiles: scan the QR code, choose which profile to activate, etc.
4. Once installed, you can switch eSIM profiles or store multiple profiles, depending on the model you purchase and the number of profiles allowed.

Some providers, like JMP, offer apps for various platforms ( Android , Windows , macOS, Linux ), providing greater versatility. Others, like eSIM.me, focus on Android and usually have up-to-date compatibility lists for popular smartphones.

Important tip : Before buying, always check the list of compatible devices on the eSIM adapter provider's website. Not all phones can handle the setup, especially if they don't support the Open Mobile API (OMAPI) , a technical requirement for some Android models.

Advantages and disadvantages of using a SIM with an eSIM profile on non-compatible mobile phones

Using these types of adapters and hybrid cards opens up new possibilities, but also has nuances to consider.

main advantages

• Total flexibility: You can change operators or rates without changing your physical SIM.
• Ideal for traveling: Install a local eSIM profile in seconds and avoid expensive roaming.
• multiple profiles: Some adapters allow you to have multiple profiles stored and switch between them from an app.
• No physical loss: The eSIM is virtual, you can't break it or lose it.
• More sustainability: Less plastic waste by not requiring new physical SIMs for each operator or trip.

Disadvantages and limitations

• Limited compatibility: Not all “non-compatible” phones will be able to use these adapters.
• Slightly more complex installation and management: : usually requires additional apps.
• Third party dependency: The quality of support and updates depends on the company that makes the adapter.
• On older phones, management may be unstable. (especially on older versions of Android).
• Some eSIM profiles can only be installed once.If you delete your profile, you typically won't be able to reuse the same QR code.

Steps to install an eSIM (or eSIM profile) on an incompatible phone

The process varies depending on the adapter brand, but generally it goes like this:

1. Buy an eSIM adapter trusted (eSIM.me, JMP, 5ber…)
2. Check compatibility on the seller's website.
3. Insert the SIM card with eSIM profile into your phone's SIM slot.
4. Download and install the management app provided by the adapter manufacturer.
5. Open the app, add an eSIM profile by scanning the unit’s QR code provided by your operator or eSIM provider.
6. Follow the on-screen instructions to complete the installation. Accepting the settings and selecting the active profile is usually sufficient.
7. In some cases, you'll have the option to add multiple eSIM profiles and switch between them using the app.

The main difficulty lies in profile management and the compatibility limitations of certain Android phones. For example, some models do not support the OMAPI standard , which prevents the app from correctly configuring the card.

Which phones support eSIM and which don't?

Currently, most phones that support eSIM are high-end . Here's some guidance:

• Apple : All iPhone models from XS/XR onwards (iPhone XS, XR, 11, 12, 13, 14, 15, 16, etc.). Starting with iPhone 13, they support dual active eSIM (Dual eSIM). For more model details, see this article.
• Samsung: Mainly S series (S20, S21, S22, S23, S24, etc.), some foldable models, and most Ultra models. See details for A and M series.
• Google: Pixel 3 onwards, but newer versions (Pixel 7, 8, 9…) have better support for Dual eSIM.
• Other Android manufacturers: There are advances in brands such as Xiaomi, HONOR, OPPO, Huawei, Motorola, Sony and some models of DOOGEE, Planet Computers, Rakuten, Sharp…

If your phone isn't listed in the official database, check your settings : if you see an option to "Add eSIM" or "Add mobile data plan," you're in luck and can install native profiles. Otherwise, you'll need to use an adapter.

Can I use two eSIMs or combine an eSIM and a physical SIM?

On devices that officially support eSIM, almost all allow combining eSIM and physical SIM , which allows you to have two active lines (ideal for separating work and personal life, or for travel).

The Dual eSIM feature (using two eSIMs simultaneously) is limited to specific models. For example, on Apple devices, all iPhones from the iPhone 13 onwards allow two active eSIMs at the same time, while on Android, compatibility depends on the manufacturer (see the guide for managing roaming ).

On phones that are not factory-supported, dual eSIMs are not possible due to technical limitations. In most cases, you will be able to manage multiple saved profiles, but only one can be active at a time.

How much does an eSIM cost and where can I buy it?

The cost of using an eSIM depends on two factors:

• The SIM adapter with eSIM profile: between €25 and €35 ​​on average, depending on the model and number of profiles allowed.
• The eSIM profile or data plan: You can buy them on websites like Holafly, HolaSim, or directly from the traditional operator (Movistar, Vodafone, Orange, etc.), with prices that vary greatly depending on the destination and duration (from global plans starting at $30 to packages for Europe at around $50 per month).

Some companies, such as HolaSim, don't charge for the eSIM itself, only for the associated data plan. Payment is usually a one-time fee for the adapter card, and recurring fees apply for each new eSIM profile installed.

Recommendations before purchasing and installing a SIM with an eSIM profile

Before embarking on this technological adventure, keep these tips in mind:

• Check the compatibility of your mobile on the adapter supplier's website.
• Check how many eSIM profiles you can manage at once (some only allow two, others up to five or more).
• Make sure your phone supports OMAPI If you're using Android, this is essential for the app to write to the SIM adapter.
• Store your eSIM QR codes and profiles in a safe place.Many operators do not allow reuse of them after deletion.
• Suspicion of very low prices in adapters or little-known services.
• Be careful with permissions rootSome apps, such as OpenEUICC, require root and can be complicated to navigate for less experienced users.

What if I deactivate the SIM slot with an active eSIM profile on my phone?

On Android phones, especially from version 13 onwards, there is a small drawback: if you disable the SIM slot where the eSIM.me card (or other adapter) is inserted, the active eSIM profile may become inaccessible until you reset the phone to factory settings or follow an advanced guide like XDA Developers.

This happens because the operating system assigns an identification code (CardID) to the active configuration, and if the slot is disabled, that CardID is marked as "deactivated," with no way to manually reactivate it. Before deactivating anything, be sure to first disable the eSIM profile in the carrier's app.

Which operators and countries offer eSIM?

The eSIM is an increasingly widespread technology. For example, in Spain, most major operators (Movistar, Orange, Vodafone) offer eSIM as an alternative to a physical SIM, even free for new subscribers. In Latin America, adoption is progressive, with countries such as Argentina, Uruguay, Chile, Mexico, Colombia, Paraguay, and Peru already offering this service through major telecoms (Movistar, Claro, Personal, AT&T, Telcel, Entel, Tigo, Bitel, etc.).

If you purchase an international eSIM profile, such as those from Holafly or HolaSim, you can access data in more than 140 countries without changing your physical SIM, simply by installing the profile sent to you by email on your adapter.

Can I use the eSIM on wearables, tablets, or other devices?

The adoption of eSIM is also extending to smartwatches, tablets, and laptops . The principles are the same: if the device supports eSIM or you can install an adapter with an eSIM profile, you'll enjoy the benefits of this technology without physical restrictions.

To recap, eSIM represents the future of mobile connectivity , and while manufacturers are pushing you to buy new models, there are safe and reliable solutions to enjoy its benefits on all types of phones. Whether for savings, convenience, or flexibility, opting for a SIM with eSIM profile is a smart decision, as long as you follow compatibility guidelines and security advice. The market for hybrid adapters will continue to improve, so stay tuned for new developments and don't get left behind in this digital revolution.
