Dual SIM IMEI check

Client

Dual-SIM phones expose two modem IMEIs (or one IMEI plus eSIM profile context). Paste each slot IMEI on separate lines for local Luhn—no carrier dual-SIM registration lookup.

Dual-SIM intake checklist

Copy SIM1 IMEI → copy SIM2 IMEI → paste both here → confirm both Luhn pass → record in asset ticket before carrier activation.

Privacy: digits are parsed only in your browser—no carrier or GSMA lookup, no upload. Treat device identifiers like any sensitive paste on shared machines.

A 15-digit IMEI is commonly described as eight-digit TAC + six-digit serial + Luhn check digit; the trailing digit should satisfy ISO/IEC 7812 mod 10 on the full string—same arithmetic as debit/credit PAN checks. A 16-digit IMEISVappends two software version digits instead of exposing the standalone check position; carriers may still relate it to IMEI numbering but this page stops at segmentation and does not certify assignment.

Result

Passes Luhn mod 10 on the 15-digit string.

  • TAC (8): 35693803
  • Serial (6): 564380
  • Check (1): 9

Common use cases

  • Validate both IMEIs on import manifests for dual-SIM SKUs.
  • Support troubleshooting when only one slot activates.
  • Reseller listings that must disclose both modem IDs.

Common mistakes to avoid

  • Pasting the same IMEI twice for dual-SIM

    True dual-modem devices have distinct IMEIs per slot—re-copy from settings.

  • Confusing second IMEI with ICCID

    ICCID is the SIM serial—different field on About screens.

  • Expecting dual IMEI check to prove both lines active

    Format only—not live line status per slot.

FAQ

Do dual-SIM phones have two IMEIs?

Dual-standby models typically expose two IMEIs—one per cellular modem path.

How to paste both?

One IMEI per line in bulk mode; label rows in your spreadsheet.

Single SIM mode—still two IMEIs?

Hardware may still report two—validate both if printed on the label.
