eSIM profile serial check

Client

eSIM profile serial check focuses on the ICCID tied to a downloaded profile—not the eUICC EID chip identifier. Paste profile serial digits to run Luhn before escalation to carrier or SM-DP+ support.

Profile serial vs EID

Paste the decimal ICCID profile serial. Keep EID and IMSI fields separate in support templates.

Privacy: digits are evaluated only inside your browser. There is no carrier, GSMA, or SM-DP+ query—format math only. Treat SIM identifiers like any sensitive operational paste.
?

The ITU‑T E.118 layout follows ISO/IEC 7812 for card identifiers: a Major Industry Identifier (telecom ICCIDs usually start with 89), an issuer/country/account block, then a trailing Luhn mod‑10 check digit using the same doubling rule as many payment PAN validators. Printed cards commonly show 18–22 digits; issuers pin one length profile per range.

Result

Passes Luhn mod 10 on the full 19-digit string.

  • MII (first 2): 89
  • Issuer / account core (between MII and check): 3530012345678901
  • Check digit (last): 1

Common use cases

  • Confirm profile serial copied from iOS/Android cellular settings.
  • Validate reseller eSIM voucher CSVs before customer delivery.
  • Distinguish profile ICCID from activation codes in email PDFs.

Common mistakes to avoid

  • Checking EID when the ticket asks for ICCID

    EID identifies the eUICC chip; ICCID identifies the profile.

  • Expecting profile check to reveal SM-DP+ status

    No SM-DP+ or carrier provisioning query on this page.

  • Deleting a profile because Luhn failed

    Fix paste errors first—failed Luhn often means a typo.

FAQ

Where is eSIM profile ICCID shown?

Device cellular/eSIM settings, carrier app, or confirmation email—wording varies.

Is profile serial the same as activation code?

No—activation codes are separate from the ICCID digit string.

Does this install an eSIM?

No—format validation only.
