SOURCE: LG enV phone locked and can't get it unlocked?? don't know the last phone # for it either


Ok, I checked out this problem and have the solution. The others are right it should
be the last four digits of your number. But if it still dont work, do this....(When your phone
is locked you can still call E911 or VZ special calls) So dial *228, press SEND, listen and when it ask you to select, press number 1. Give it a minute and it will say programming sucessful and then automaticly restart the phone. When it comes back on your phone will still be locked, but this time the code will be your last four digits. :) This should work for everyone...%100.

(very rarely when you dial *228 it will say programming unsucessful) just manualy restart your phone and if it still does this, just be patient the verizon system is down..BUT THIS RARELY HAPPENS.

I also have a problem. I've been working with computers since I was 10 yrs old. I also went 2 yrs. in college major in computer science but I put it on hold trying to get a construction business started. Well, last year I was in very bad accident disabling me. I'm 30 yrs. old and a single
father of two. I will draw SSI eventually, but very little. I've always made sure my kids
had a good life even after there mom left. Well, im on the verge of loosing everything. And computer work is all that I can do now. Can any of you tell me where I can find a good online job? I see all of those advertising about online jobs,but most of them are scams or invest now, make later. I need a online job that I can start making money pretty fast. I would really appreciate it if anyone can direct me in the right way of a good online job. For now any small job could help..

Thanks, Ge Johnson

My phone is restricted. . .i need to enter a restriction code but i don't know the code. . .i don't even know how it was restricted. . .please help me. . .

If your mobile phone displays Phone Restricted with an Undo option and selecting Undo results in an Enter Restriction Code error, your mobile phone is Network Locked. This means your mobile phone has been restricted for use on one specific network and a Restriction Code or Unlock Code must be entered before the phone can be used with alternative networks.You can get the Restriction Code at here
