Is my phone eSIM compatible? Check before you buy

A phone is ready for a travel eSIM only when its exact variant supports eSIM, the feature is available in settings and another carrier is allowed.

A phone is ready to proceed only when the exact regional variant, the eSIM-addition path and unlocked status agree.

Before buying a travel eSIM, confirm the exact model and sales region on the manufacturer’s support page, find an Add eSIM option in the phone’s settings, and verify that the phone is carrier-unlocked. A familiar model name or an EID alone does not guarantee that a particular plan can be installed.

Read what the phone actually tells you

These are evidence checks, not a simulated phone screen. Menu names can change with device and operating-system version.

  1. MODEL + REGION

    Start with the exact model, not the marketing name

    Action
    Open About phone and copy the full model number, then check that number on the manufacturer’s support or specifications page. The country or sales region matters: Apple notes that cellular options are not available on every model or in every country and region, while Google documents model-and-carrier exceptions for older Pixel devices. A list that says only “iPhone”, “Galaxy” or “Pixel” is not enough evidence for the device in your hand.
    What you should see
    A complete model identifier and original sales market
    What it means
    If the phone was imported, refurbished or supplied by a carrier, also confirm its original sales market. Do not infer eSIM support from the presence or absence of a physical SIM tray; hardware arrangements vary by model and region. [apple-cellular] [google-pixel-sim]
  2. ADD eSIM

    Check whether the phone can add an eSIM

    Action
    On iPhone, open Settings, then Cellular or Mobile Data, and look for Add eSIM. On a Samsung Galaxy, the usual route is Settings, Connections, SIM manager; on Pixel it is Settings, Network & internet, SIMs. Menu names can move with an operating-system update, so use the settings search and the current manufacturer guide if the route differs.
    What you should see
    An Add eSIM or Add SIM path, or a clearly missing/disabled path
    What it means
    An EID in About phone is evidence that the device has an eSIM identifier, and Google explains that an EID is needed to use eSIM. Treat it as a supporting check, not a promise that every provider or plan will activate on that phone. [apple-cellular] [google-pixel-sim] [samsung-esim]
  3. CARRIER LOCK

    Confirm that another carrier is allowed

    Action
    eSIM hardware and an unlocked phone are separate checks. Apple says an unlocked iPhone shows “No SIM restrictions” beside Carrier Lock in Settings, General, About. Google likewise explains that a SIM-locked Pixel can use only the seller’s network until the seller removes the lock or the contract ends.
    What you should see
    Unlocked, locked, or still unknown
    What it means
    For other Android phones, ask the carrier that sold the device and give the exact model or IMEI if requested. Letisim cannot remove a carrier lock. Do not buy until the carrier has confirmed the status if settings are unclear. [apple-unlock] [google-pixel-unlock]

Device Readiness Board: choose the safe branch

Do not average conflicting signals. One unresolved condition keeps the purchase decision in verify-first.

READY

Proceed to the live plan

  • All three device checks agree
  • Read the selected plan’s current instructions before payment

VERIFY

Stop and resolve the mismatch

  • A menu, model region or lock state is unclear
  • Ask the manufacturer or original carrier before buying

ALTERNATIVE

Use another connection route

  • The regional variant lacks eSIM or the phone stays locked
  • Use a supported unlocked phone or another connectivity option

Make the purchase decision without guessing

Proceed to the live catalog only after all three checks agree: exact regional variant, an eSIM-addition path, and carrier-unlocked status. Then read the selected plan’s live description before payment because device hardware support is not the same as compatibility with a particular plan or network. [apple-travel] [google-pixel-sim]

If any check fails, use a supported unlocked phone or choose another connectivity option for the trip. If the evidence conflicts, contact the device manufacturer or original carrier first and send Letisim support the model number—not a full EID, IMEI, QR code or activation code.

Save this non-sensitive readiness card

Keep only the facts support needs; never copy activation secrets.

  • Full model number
  • Original sales country or region
  • Operating-system version
  • Whether Add eSIM is present, absent or disabled
  • Carrier-lock result and who confirmed it
