Telefonumun eSIM destekleyip desteklemediğini nasıl kontrol ederim?
En hızlı kontrol: hücresel ayarları açın ve "eSIM Ekle" veya "Hücresel Plan Ekle" seçeneğine bakın. iPhone'da *#06# çevirmek bir EID gösterir — EID varsa donanımda eSIM çipi var demektir. Ayrıca telefonun operatör kilidi olmadığını doğrulayın.
Whether a given phone supports eSIM depends on two things that are entirely separate from one another. The first is the physical hardware chip the manufacturer built into the unit at the factory. The second is the software status and any condition the original seller attached to that specific device, such as a carrier lock. Neither of these is guaranteed simply by a model name, because many manufacturers ship the same-named model in several regional variants, and some of those variants leave the eSIM chip out entirely so the phone can be sold as a physical-SIM-only device in a particular country. Reading online that 'this model supports eSIM' is a starting point, not proof — you always need to check the actual unit in your hand.
This page is written for anyone about to buy an eSIM plan for an upcoming trip who is not yet sure their phone supports it, anyone who picked up a second-hand phone with an unclear history, anyone who has just switched from Android to iPhone or the other way round, and anyone using a company-issued phone that might carry special restrictions. We walk through the fastest checks first, then the points where people commonly get the wrong idea, and finally what to do next if the check comes back unsupported.
The fastest check, on your own device
- 1Open the cellular or mobile network menuGo into the phone's settings and look for a menu related to cellular, mobile data, or mobile network. The exact wording differs by manufacturer and software version, so look for anything close to this rather than one fixed phrase.
- 2Look for 'Add eSIM' or 'Add cellular plan'If this option appears, the phone most likely has the eSIM chip built in. If you cannot find it at all, do not immediately conclude it is absent — some phones hide this menu until the latest software update is installed, or until the network lock is removed.
- 3Dial *#06# on an iPhone, or look for an EID in the device information menuMost iPhones with eSIM show an EID number when you dial *#06#, or under General settings > About. Seeing this number confirms the hardware carries an eSIM chip.
- 4Check the exact model and the market it was sold inOpen the model number in the device information menu and compare it against what the manufacturer publishes for the market you bought it in, since the same-named model sold abroad can carry a different sub-model number with different capabilities.
- 5Check carrier-lock status separatelyEven where the eSIM chip exists, if the phone is still locked to its original operator, a connection to a destination network can still be refused. This check is separate from the hardware check and always needs doing on top of it.
On iPhone: what else to look at
iPhones with eSIM have existed since models first sold from 2018 onward, but 'this model supports it' does not mean every unit sold under that model name is identical, since Apple has made certain regional variants of some models with two physical SIM trays and no eSIM at all. The most reliable signal is your own device checked through the steps above, not the model name by itself.
An iPhone that has had its logic board repaired or replaced can sometimes show an inconsistent eSIM status, or an EID that does not match the one printed on the original box. This is uncommon, but if it happens, it is best to ask the repair centre that serviced the phone rather than guessing.
On Android: menus vary by manufacturer
Android has no single standard menu for eSIM, because each manufacturer designs its own settings interface. Common wording includes 'SIM manager', 'add mobile plan', or something close, tucked inside a network and internet menu or a connections menu, depending on the brand and the software version. Some phones require going one level deeper into a sub-menu before the option appears.
It gets more complicated because the exact same Android model on a different software update can show a completely different-looking menu, since manufacturers reshuffle their settings layout across update cycles. The safest approach is to use the search box inside the settings menu, type 'eSIM', and see whether a result appears, rather than clicking through menus by hand.
Signals that suggest support, or the lack of it
| Signal you see | What it suggests |
|---|---|
| An 'Add eSIM' menu appears in settings | The hardware most likely carries an eSIM chip |
| Dialling *#06# shows an EID number | Confirms an eSIM chip is physically present |
| Only two physical SIM trays, no eSIM menu at all | May be a regional variant with eSIM removed — verify the exact model |
| Software is well behind the latest version | Update the software first, then check the menu again |
| The manufacturer lists this model as eSIM-capable on its official spec page | Good supporting evidence, but still worth confirming on your own unit |
Checking carrier lock, as a separate step
Even where a phone carries the eSIM chip in full, if it is still locked to its original operator from being sold with a contract or a subsidised price, the modem can flatly refuse to connect to a different destination network, even though the eSIM profile installs successfully and shows up in the list. Installation only saves the profile file onto the device; it is not an actual network connection. The problem appears separately, once you switch that line on.
The most direct check is to ask the operator you bought the phone from, with the IMEI number ready in advance, since they are the only party who knows the lock status for certain. Another option is to try a physical SIM from a different network once before travelling — if it connects normally, the phone is no longer locked.
Common mistakes people make when checking their phone
Using more than one eSIM profile at once
Many phones can store more than one eSIM profile at the same time, but the number that can actually be active simultaneously varies by model and software version. Some phones run one profile at a time; others can run two together. If you plan to use our eSIM alongside your existing SIM or another eSIM at the same time, check this limit on your own device first, since we cannot confirm on your behalf how many profiles your particular model supports.
If the phone does not support it, what next
If you have gone through every step above and still find no signal that the phone supports eSIM, the remaining options are a physical SIM at your destination, or a portable Wi-Fi device if the main handset genuinely does not support it. Both of those are device-side choices you would need to research further, since they are not something we provide directly.
Before concluding that, try our device checker tool first, since it gathers capability information for various models in one place, faster than hunting for it yourself, though its result should still always be confirmed against the check on your own actual device.
A quick self-check: reassuring signs versus warning signs
| Situation | What it means |
|---|---|
| Bought a brand-new, unlocked handset directly from an authorised store in Thailand | Higher chance of support and no lock, but still worth confirming with the steps above |
| Second-hand phone with an unknown purchase history | Needs both hardware and lock status checked carefully before buying a plan |
| Phone imported from a market known for selling feature-reduced variants | Verify the exact sub-model number against the manufacturer's data for that specific market |
| Company-issued phone with restricted permissions | Check with the organisation's IT department first, since some phones have menus deliberately locked |
Checklist before buying an eSIM plan
- Open cellular settings and look for 'Add eSIM' or similar wording
- Dial *#06# or open device information to look for an EID
- Check the model number against the market it was sold in
- Ask the original operator whether the phone is carrier-locked
- Update the phone's software to the latest version before the final check
- If still unsure, try the device checker tool or ask us before buying
If you are still unsure after all these checks
Some phones carry conditions that do not fit the general cases above — a device that has had its logic board repaired, one recalled and partly replaced by the manufacturer, or one bought through a niche instalment programme. If you have checked everything and are still unsure, do not keep guessing: message us before buying a plan. We can help read a model number and explain what else to check, though the final answer on whether that particular unit connects always rests on its own hardware and lock status.
If you are buying a new phone specifically to use eSIM while travelling
Anyone planning to buy a new phone ahead of a trip often assumes picking a model advertised as 'eSIM-capable' is enough on its own, but many manufacturers position this capability differently across sub-models within the very same product line. A cheaper model in a range can drop the eSIM chip even where a pricier sibling keeps it. The safer route is to ask the shop staff to open the cellular settings menu and show it working, before handing over payment, rather than trusting a price tag or a brochure alone.
A phone sold with a promotional operator contract usually comes carrier-locked from the outset, even though it costs noticeably less than an unlocked one. Requesting an unlock afterwards takes time and follows that particular operator's own conditions. If you are buying a phone to travel with soon and do not want to risk the unlock timeline, paying more for a handset that is unlocked from the start is usually more predictable, though the price trade-off is worth weighing case by case.
What our device checker tool can confirm, and what it cannot
The device checker tool on this site draws on specification data that manufacturers publish publicly for each model number, letting you filter through a lot of models faster than researching each one by hand. But because it relies on what manufacturers have published, a market-specific sub-variant that is not fully documented in that public data will not always show up correctly. Its result is a good starting point, not a final answer.
One thing this tool can never tell you is carrier-lock status, since that is information only the operator who originally sold the device knows for certain. No matter how clearly the device checker confirms a model supports eSIM, you still need to check lock status separately. These are two different questions, and both need answering before you can be fully confident.
A borrowed or temporarily lent phone
If the phone you plan to travel with is not your own, such as one borrowed from family or a spare handset from someone else, check every step on this page directly on that phone, rather than assuming it will match your own familiar device. Hardware status and carrier lock are properties of that specific unit, not of you as the user. It is also worth telling the owner in advance that you will be installing an eSIM profile on their phone, in case they want the device back to its normal state once the trip is over.
SSS
My phone has two physical SIM trays — does that mean it has no eSIM?+
Not necessarily. Some models carry both two physical SIM trays and an eSIM chip, while others carry only one or the other. The surest way to know is to check the settings menu using the steps on this page.
Can I check compatibility before buying anything?+
Yes. Checking the settings menu, dialling *#06#, and using our device checker tool on the site all cost nothing, and should always be done before buying a plan.
I see an EID after dialling *#06#, but 'Add eSIM' is greyed out — why?+
This is usually caused by carrier locking or a software restriction set by the original operator. Check the lock status directly with that operator, since the hardware chip may already be present but unusable until the lock is removed.
Can I run the eSIM alongside my existing physical SIM at the same time?+
It depends on the model and software version. Some phones can run two lines at once, others only one at a time. Check this limit on your own device before relying on it.
I'm not sure which regional variant my phone is — where do I check?+
Open the device information menu to find the model number, then compare it against the manufacturer's official published data, or ask the retailer that sold it, rather than inferring from the model name alone.
Does the same method work for checking a smartwatch or tablet?+
The general idea is similar — check that device's own settings for anything mentioning eSIM — but the menu and its limitations differ a good deal from a phone, so it is worth checking that device's own specific guidance instead.
