Affidavit of Loss for a Lost SIM Card

Telcos may ask for an affidavit of loss before they issue a replacement SIM with the same number. Fill in the form to generate yours.

What to prepare

  • The mobile number
  • Name the SIM is registered under (SIM registration)
  • Date and place of loss
  • Valid government ID

Good to know for this situation

  • Ask the telco to block the SIM right away so it cannot receive one-time PINs for your bank or e-wallet.
  • The name on the affidavit should match the SIM registration.
  • Some telcos replace SIMs in-store with only an ID; ask first.

Questions

Why is a lost SIM risky?
Banks and e-wallets send one-time PINs to your number. Block the SIM first, then request the replacement.
Do all telcos require an affidavit?
No. Some only need a valid ID that matches the SIM registration. Requirements can differ by office and change over time, so confirm with the office that will receive the document before you have it notarized.
