Xiaomi Redmi 4A

A Xiaomi Redmi 4A is locked the same way any Xiaomi handset is: the carrier that sold it holds a record against the IMEI, and the device refuses every other SIM until that record changes. This page shows how the model is identified in the TAC register, what kind of lock it uses, and which of our services apply.

How a Xiaomi Redmi 4A is identified

The TAC — the first eight digits of the IMEI — is how the register knows which model a handset is, and it is what every unlock and warranty service actually queries. Our register holds 62 TAC ranges under this model name:

The register dates this model to 2016, which decides how it is locked: handsets of that generation and market follow the rules described below.

Which lock does this model use

Most handsets from this brand are either code-locked (the phone prompts for a network code when a foreign SIM is inserted) or released by the carrier that sold them. Which one applies depends on the model year and on whether it was sold through an operator — the IMEI check tells you before you pay for anything.

On a Xiaomi Redmi 4A the practical test is simple: insert a SIM from a different network. If the phone asks for a code, it is code-locked. If it refuses with “SIM Not Supported” or a carrier-lock notice, it is server-side locked and has to be released against the IMEI. If it just works, it is already unlocked.
