Unlock guide
An OPPO A11k is locked the same way any OPPO 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.
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 42 TAC ranges under this model name:
| TAC prefix | Look it up |
|---|---|
86003004 | run the lookup |
86024504 | run the lookup |
86030204 | run the lookup |
86036304 | run the lookup |
86039705 | run the lookup |
86070305 | run the lookup |
Dial *#06# to read the IMEI, then compare the first eight digits. Not listed? The lookup will still resolve the model if the range is filed under a different name.
The register dates this model to 2020, which decides how it is locked: handsets of that generation and market follow the rules described below.
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 an OPPO A11k 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.

Unlock prices depend on the carrier and the model generation, so the same handset costs different amounts depending on who sold it. These are the carriers we hold a service for:
