Unlock Optimus Galaxy A15 by IMEI

Power the phone off, fit a SIM from the network you are moving to, and power it back on. It asks for a network unlock code as it starts up — enter the one we email you and the lock is gone for good.

Enter it exactly as it appears, and do not try codes from anywhere else first: only the code generated for your IMEI will be accepted.

Whichever ones it asks for — and you get all of them. A Samsung is not always a single code. The NCK is the network code most handsets ask for; an MCK unfreezes the code entry if wrong codes have already been tried; and some models ask for an RGCK for a regional lock. We send every code your handset needs, not just one.

Yes. An outstanding instalment balance or an active contract does not stop us. You still owe the balance to your carrier — unlocking does not cancel the debt — but it no longer stops you using another network.

No. We never ask for your Optimus account number, password or PIN, and we do not contact them on your behalf. All we need is the IMEI and an email address to send the result to.

That is fine, and it is exactly the case carriers refuse. We do not need the account holder, the account number or any permission from them — only the IMEI.

Use our IMEI network checker before you order. It reads the carrier off the IMEI, so you are not guessing at the dropdown.

We do not unlock handsets reported lost or stolen. An unlock removes a carrier lock, not a blacklist report, so a barred IMEI would stay barred anyway. We check this as part of processing your order.

Yes. Once the code is accepted the lock is gone for good, and neither a software update nor a factory reset brings it back.

Neither. Nothing on the handset is modified, so a warranty inspection has no change to find, and your photos, apps and messages are untouched.

Yes. Unlocking adds networks, it does not take one away — the handset keeps working exactly as it does today, and you can move between networks whenever you like.
