Quick Answer: The most reliable way to check if your phone supports eSIM is not by just looking up its model name. Instead, you should check your phone's settings directly to see if options like "Add eSIM" or "Set up an eSIM" appear, and confirm whether the device displays an EID. Beyond that, you must verify your exact model number, the region it was sold in, and whether it is restricted by a carrier lock. Even if a specific phone line generally supports eSIM, certain regional models may have exceptions or limitations.
Before purchasing a travel eSIM, many people simply search, "Does my phone model support eSIM?"
While this is a good starting point, it isn't entirely reliable. A single product name can cover several regional versions, and their SIM card configurations, software capabilities, and carrier restrictions can vary significantly.
For example, whether it's an iPhone or a Samsung Galaxy:
- Versions sold in different countries may have completely different SIM tray designs.
- A model might generally support eSIM, but a specific regional version does not.
- Your phone might have the required eSIM hardware but is locked by your original carrier.
- Older operating system versions might show different settings menus.
- Just because a phone supports eSIM doesn't guarantee every carrier or travel plan will support that exact device.
Therefore, you should run a three-step check before buying:
- Does the eSIM management feature exist in your settings? 2. Does your exact model number and sales region support it? 3. Is the phone unlocked from your home carrier? ## The Fastest Universal Checking Method
First, open your phone's Settings and type any of the following into the search bar:
- eSIM
- SIM
- Cellular
- Mobile Data
- SIM manager
- Mobile network
If the search results show any of the following options, your device likely has eSIM management capabilities:
- Add eSIM
- Set up an eSIM
- Download a SIM
- Scan QR code
- Add mobile plan
- Add Cellular Plan
However, seeing these options does not guarantee you can use any travel eSIM. You still need to verify your exact model, regional version, and network lock status.
Method 1: Check If Your Phone Has an EID
An EID (eUICC Identifier) is a unique serial number for the embedded SIM component in your device.
Phones that support eSIM usually display an EID. You can try the following methods to find it:
View in Settings
The exact path may vary by brand, but common locations include:
- Settings → General → About - Settings → About phone → Status information - Settings → About phone → SIM status Look for any of these terms on the page:
- EID
- eSIM
- IMEI2
- Digital SIM
View via the Dialer
On some phones, you can open the Phone app and dial:
*#06#
The system will display your IMEI, EID, or other device identifiers.
If you see an EID, it generally means your device contains an eSIM component. However, this still does not replace checking for regional versions and carrier locks.
Privacy Warning: Your EID, IMEI, and serial numbers are sensitive device identifiers. Do not post the full numbers on public forums, social media, or unfamiliar websites. If you need to contact official customer support, only share them through trusted channels.
How to Check iPhone eSIM Compatibility
Step 1: Look for "Add eSIM"
Open:
Settings → Cellular
(Note: Apple may label this section "Cellular" or "Mobile Data," depending on your device's region and language settings.)
Depending on your iOS version, you may see:
- Add eSIM
- Set Up Cellular
- Add Cellular Plan
If the page gives you options to scan a QR code, transfer from a nearby iPhone, or enter details manually, your iPhone likely supports eSIM configuration.
Step 2: Check for an EID
Open:
Settings → General → About
Scroll down and look for EID.
Apple officially lists "Settings → General → About" as the standard way to view your EID, IMEI, and other device identifiers.
Step 3: Check for Carrier Locks
Even if your iPhone supports eSIM, if it is locked to your original carrier, you may not be able to use a travel eSIM from another provider.
Open:
Settings → General → About → Carrier Lock
If it says:
No SIM restrictions
This means your iPhone is unlocked and can be used with other carriers.
If it says anything else, you must contact your original carrier to request an unlock. Apple cannot remove carrier locks on behalf of telecommunications providers.
Step 4: Verify Your Exact Model and Sales Region
Apple generally lists the iPhone XS, iPhone XS Max, iPhone XR, and all later models as supporting eSIM. However, there are crucial exceptions depending on the country and region where the device was sold.
Do not just rely on the product name like "iPhone 15," "iPhone 16," or "iPhone 17." Instead, open:
Settings → General → About → Model Number
Tap the part number next to "Model Number" to reveal the full model number starting with the letter ** A**. You can then cross-reference this "A" model number on Apple's official tech specs or SIM type support pages.
Exceptions for iPhones Sold in Mainland China
iPhones sold in mainland China are among the most common sources of confusion.
As of this article's last update, Apple's official support page for mainland China states that the iPhone models supporting eSIM in mainland China include:
- iPhone 17e (Model A3635)
- iPhone Air (Model A3518)
Apple also clarifies that other iPhone models generally cannot install eSIM profiles provided by mainland China carriers, and this restriction applies to some models purchased outside mainland China as well.
Because rules change based on regulatory environments, if you are using a mainland China version or are located in mainland China, you must check:
- Your exact "A" model number.
- Whether "Add eSIM" actually appears in your Settings.
- The specific compatibility notes on Caylet's product page.
- Contact customer support if needed (providing your model number, but not your full IMEI or EID).
Exceptions for iPhones Sold in Hong Kong and Macau
Certain iPhone models sold in Hong Kong and Macau were manufactured with a dual nano-SIM tray design rather than the standard "Physical SIM + eSIM" configuration. This varies across generations and specific models, so you cannot assume it supports eSIM just because it is a recent iPhone.
The most reliable method is still to:
- Check the full "A" model number.
- Look for "Add eSIM" under Cellular settings.
- Verify against Apple's official SIM type documentation.
How to Check Samsung Galaxy eSIM Compatibility
Samsung Galaxy eSIM support is heavily influenced by the model, country of sale, carrier version, and system software.
Step 1: Check SIM Manager
Open:
Settings → Connections → SIM manager
If the page displays:
Add eSIM
And it allows you to choose between scanning a QR code or entering an activation code, this generally means your Galaxy device has eSIM functionality.
Step 2: Check the Device Model
Open:
Settings → About phone
Record both the "Model name" and the actual "Model number." Phones in the same series can have different regional codes, so you cannot rely solely on names like "Galaxy S series" or "Galaxy Z series" to confirm compatibility.
Step 3: Ensure the Phone Is Unlocked
If your Galaxy phone was purchased through a carrier contract, an installment plan, or as a customized version, it might be restricted by a network lock.
Unlike Apple, Android brands and carriers do not have a uniform way of displaying lock status. If you aren't sure, you can:
- Check your original purchase receipt or contract.
- Contact your original carrier.
- Try navigating the "Add eSIM" process without deleting your current SIM to see if it allows you to add profiles from other providers.
- Never rely on sketchy third-party "IMEI unlock websites" to submit your device info.
Why Do Online Compatibility Lists Often Contradict Each Other?
Common reasons include:
- The same model has different capabilities across different global markets.
- Certain carrier versions disable specific hardware or software features.
- eSIM functionality was added later via a software update.
- Different dual SIM configurations exist.
- The lists are outdated.
For Samsung phones, always rely on the combination of your device settings, your exact model number, and the official specifications for your local market.
How to Check Google Pixel eSIM Compatibility
Step 1: Look for "Set up an eSIM"
Open:
Settings → Network & internet → SIMs → Add SIM → Set up an eSIM
If you can enter the flow to select a network provider, scan a QR code, or download a SIM, your device likely supports eSIM.
Step 2: Check the Exact Model and Purchase Source
Google states that Pixel 4 and newer models generally support eSIM, while earlier models like the Pixel 3 and Pixel 3a have carrier and regional exceptions.
Even for the same generation of Pixel, you should confirm:
- Which country it was purchased in.
- Whether it is a specific carrier version.
- Whether the network lock has been removed.
- Whether the system software is fully updated.
- Whether "Set up an eSIM" actually appears in your settings.
Step 3: "Dual SIM Support" Does Not Mean "Supports All eSIMs"
Some Pixel phones can use one physical SIM and one eSIM simultaneously. Newer models might support keeping two eSIM profiles active at once. However, these capabilities are still restricted by the device model and carrier support.
For travelers, the most important factor is not how many profiles your phone can store, but rather:
- Can it successfully add a travel eSIM from Caylet?
- Can it connect to partner carriers at your destination?
- Can you set the travel eSIM as your active mobile data line?
How to Check Other Android Phones
For brands like Motorola, Xiaomi, OPPO, vivo, Honor, Huawei, Sony, and others, the situation is more fragmented.
Follow this sequence to check:
1. Search Settings
Type these into your settings search bar:
eSIM
SIM
Add SIM
Download SIM
Mobile plan
SIM manager
2. View EID
Check under "About phone" or "Status information" for an EID.
3. Check the Exact Model Number
Look at the specific model number, not just the product family name.
4. Check Official Regional Websites
Review the official product specifications or support documents for the exact region where the phone was sold. Specs from a different country's website for a phone with the same name might not apply to your version.
5. Check for Carrier Locks
Confirm with the retailer or carrier you bought the phone from that the device is fully unlocked.
6. Contact Support Before Buying
If you are still unsure, contact customer support with the following information:
- Phone brand.
- Exact model number.
- Country or region of purchase.
- System software version.
- A screenshot of your "Add eSIM" settings page.
Please obscure your EID, IMEI, phone number, and any other private information.
I Only See IMEI2. Does That Mean It Supports eSIM?
Not necessarily.
IMEI2 typically indicates that the device can recognize a second mobile line, but that second line could come from:
- A second physical SIM card slot.
- An eSIM.
- A different dual SIM configuration.
Therefore, IMEI2 is only a reference point. A much more reliable combination of evidence is:
- "Add eSIM" exists in your settings.
- The device displays an EID.
- Official specs confirm your exact model number supports it.
- The phone is unlocked.
I Have an EID. Why Can't I Install an eSIM?
Possible reasons include:
- The phone is locked by a carrier.
- Specific regional versions are restricted from using certain profiles.
- Your system software is outdated.
- The provider's system does not support your device.
- The QR code has already been used.
- Your phone has reached its maximum storage limit for eSIM profiles.
- The device is managed by a company or school that restricts network settings.
- Your Wi-Fi connection is unstable during installation.
- The plan hasn't been permitted for download yet.
Therefore, an EID is crucial evidence, but it is not the only requirement.
Difference Between "Phone Supports eSIM" and "Plan is Compatible"
"Phone supports eSIM" means the device has the hardware and software capability to download and manage digital SIM profiles.
"Plan compatibility" involves much more:
- Technical requirements of the specific eSIM profile.
- Local partner carriers.
- Supported cellular frequency bands.
- Whether the device is carrier-locked.
- Roaming agreements for the destination.
- Any artificial product limitations set by the provider.
A phone can support eSIM in theory, but still be incompatible with a specific plan. Always check both device compatibility and product descriptions before checking out. If the supported bands are limited, it might affect your local internet speed; for more details, see our eSIM Slow Data Troubleshooting Guide.

Frequently Asked Questions
Do all iPhones after the iPhone XS support eSIM?
You cannot generalize it like that. Apple lists the iPhone XS, XS Max, XR, and later models as the baseline for support, but there are exceptions for models sold in certain countries and regions. Always check the exact model number and look for the "Add eSIM" option in settings.
Can iPhones sold in mainland China use travel eSIMs?
This must be determined based on the exact model and current software rules. Just because an overseas iPhone with the same name supports eSIM doesn't mean the mainland China version will. Check for "Add eSIM," the "A" model number, Apple's latest official documentation, and the specific plan's compatibility notes.
My phone has two IMEIs. Does that mean it supports eSIM?
Not necessarily. The second IMEI might correspond to a second physical SIM card slot. Look for an EID and the "Add eSIM" option to be sure.
My phone doesn't have "Add eSIM." Will updating the software make it appear?
It's possible, but not guaranteed. If the hardware or regional version fundamentally lacks support, a software update usually will not transform it into an eSIM-compatible model. After updating, always refer to the official specifications.
Can a carrier-locked phone use a travel eSIM?
Generally, no. You cannot freely use eSIMs from other providers if your phone is locked. Request an unlock from your original carrier first, and avoid purchasing unverified remote unlocking services.
My tablet and smartwatch support eSIM. Can they use a smartphone travel plan?
Not always. A device supporting eSIM does not automatically mean it is compatible with a travel plan designed for smartphones. Tablets, smartwatches, and phones may use different provisioning flows or profile types.
Can I buy a plan first to test if my phone supports it?
We do not recommend this. Because eSIMs are digital products, issuing the installation details often triggers refund limitations. Complete your compatibility checks before making a payment.
What information does customer support need to help me?
Usually, they need your phone brand, exact model number, purchase region, system version, and a screenshot of your "Add eSIM" settings page. Please obscure your IMEI, EID, phone number, and serial number before sending.
