Affidavit of Loss for a Lost Phone

A phone is more than a device: it holds the SIM, accounts and personal data. Many banks, telcos and insurance offices ask for a notarized affidavit of loss before they replace a SIM, unlock an account or process a claim.

What to prepare

  • Phone brand, model and color
  • IMEI or serial number, if you still have the box or receipt
  • SIM mobile number and telco
  • Date, time and place the phone was lost or stolen
  • One valid government ID for the notary

Good to know for this situation

  • If the phone was stolen, file a police report as well. Some offices ask for both documents.
  • Do not put your full SIM number, account passwords or PIN in the affidavit unless the receiving office requires it.
  • Ask the bank or telco whether they need the affidavit addressed to them specifically; some provide their own form.
  • Keep a scanned copy before submitting the original.

Questions

Do I need a police report for a lost phone?
Not always, but it is safer if the phone was stolen. Banks, insurers and some telcos may ask for one. Confirm with the office that will receive the affidavit.
Can I use this for a stolen phone?
Yes, but change the wording from “lost” to “lost or stolen” only if that is accurate. Never claim a theft you cannot support; a false affidavit has legal consequences.
Will the telco accept this for a SIM replacement?
Many telcos accept a notarized affidavit of loss, but each has its own requirements. Ask first, because some require a police report or a specific form.
