Unlock AT&T Mexico by IMEI — Iusacell, Nextel, Unefón

What is this service?

It's the network unlock by IMEI for AT&T Mexico devices, using an NCK code. The NCK code (Network Control Key) lifts the network restriction set by the carrier, so you can use a SIM from any company.

It covers AT&T Mexico and its associated brands: Iusacell, Nextel and Unefón (all operate under AT&T Mexico). It works with the market's different databases, including the generic / "NOT FOUND" modality for devices not found in the direct base.

Which carriers does it cover?

• AT&T Mexico.
• Iusacell, Nextel and Unefón (AT&T Mexico brands).

How do I use the code?

1. Turn off your device and insert a SIM from another company (different from the original).
2. When you turn it on, the phone will ask for a network unlock code.
3. Enter the NCK code we send and you're done: the device is unlocked.

How long does it take?

Delivery is within minutes. The service runs 24 hours.

Important conditions
