How to Unlock the Samsung A437

As I posted earlier, I just bought a Samsung A437 as a backup phone. But what's the use of a quad-band phone if it's locked to an American network?

A short online search yielded the following unlock steps. I tried it, and now my Samsung speaks Hebrew (well, not really - but it uses my Cellcom SIM card without a hitch razz).

Caution: the following steps may cause actual damage to your phone. I do not recommend them, nor do I assume any responsibility in case you suffer any damage. Follow these steps only if you know what you're doing.

And thanks to Falcon1975, whoever you are, for originally posting these steps.
  1. Turn the phone off, take out AT&T SIM card and insert one from a different carrier. Turn the phone on.
  2. At the WRONG CARD screen type on the keypad:
    (wait 10-15 seconds - the phone will restart on its own)
  3. When phone completes reboot type:
    *7465625*638*00000000*00000000# (these are groups of 8 zeros)
  4. Next type:
    #7465625*638*00000000# (again, 8 zeros)
  5. Then type *#7465625# to check the locks.
    All locks should now be inactive:
    network lock - inactive
    subset lock - inactive
    sp lock - inactive
    cp lock - inactive
    sim lock - inactive
    activa lock - inactive
    phone lock - inactive
    auto network - inactive
    auto subset lock - inactive
    auto sp lock - inactive
    auto cp lock - inactive
  6. That's it! Your phone is now SIM, Voice and Data unlocked. Take it to a trip around the world. Phones deserve to have fun too razz.

How's the A437 in general? What's your main phone?

In general it's quite good. Good sound quality, good battery life. Going to test it in the UK this weekend - will know more after that.
My main phone is the Blackberry 8800 (been trying to replace it, but the current economy made my employer stop upgrading phones :( ).

how did u get hebrew on it

I don't have Hebrew on it per-se. What I meant is that it does show Hebrew characters, like the name "Cellcom" (when I use their SIM card).

When I enter *7465625*638*00000000*00000000# it says 'already personalized'. THen when i enter #7465625*638*00000000# it says 'wrong password'. Then when i enter *#7465625# network lock is active.
