Question about Sony Ericsson K700

1 Answer

Phone lock code

I bought my K700 2 years ago and gave it to my mom when I migrated here in the US.  She has a new phone now and sent me the K700.  The phone is asking for a phone lock code after turning it on.  I tried 1234 and 0000, but these didn't work.  I asked my mom if she knows it, she said she didn't reset any code on the phone and neither did she use any.


I intend to use a t-mobile sim.  The phone, when I bought it, was not locked to any network.  By the way, I bought it in the Philippines.


What can I do to retrieve or reset the code?

    I had the same problem with PHONE LOCK.

    For anyone who has not set the code the DEFAULT CODE is 0000.

    You can use this to set your own code - write it down to remember it!!

Facebook does not have a customer support phone line. You will need to use your laptop connection with Facebook. Sounds like a scam to gain access to your Facebook account. Use your laptop to change your password.

Have the first I phone, gave it to my Mom it was ok, she trited to add I-tunes and it went back into the original lock mode as when I bought it. It's AT &T please help her

If she tried to use it in I-tunes under her account and not yours, then I-tunes will lock the phone as a precaution. You have to deathorize the device from your account so that she can authorize it on her account. Please note that all the music/apps will be lost because they are tied to your account. Hope this helps

Best method is to simply go to a phone service that "unlocks" phones. It's cheap and reliable. Most use a computer program or have the correct codes for the phone. Plus they make it work in Australia.

Motorola razr v3-wont turn on

I am having a simuler problem. I bought my Razr V3 the 1st week of Dec of 2004. in less than 3 weeks I started having problems. I live in Western Okla. and Dobbson is my provider. When I bought my V3 Dobbson said that there was no insurance that I could buy to protect it but, that they use a compainy that for $35 will advance exchange a phone while the broken 1 is being fixed. The compainy sent me my new phone back 17-Jan-06. phone worked great! For about 4-6weeks that is. I called the repair compainy again and they told me that my waranty had expired. So I lived with the trouble I was having(check SIM)for almost 1 year. I found that by putting paper between the SIM card wire retainer & SIM the problem was deminished. Around the 1st of 2007 the phone started having more problems. Locking up, screen going blank (white), & turning itself off. I contacted the Dobbson and they gave me a new repair compainy to contact. I sent my Razr to them expecting to receive the phone back in working order. They received my phone on 6 Feb 07 and they sent it back on 7 feb 07 for the reason that my phone was out of warrenty. I went to and put in my phones ID # and was told that the warrenty had expired on 2 Feb 07. Later I found out that the 1st and 2nd repair compainy were both the same compainy. The same compainy that had told me my phone was out of warrenty approximently 1 year earlyer. I have sent a letter to Motorola about this problem and that was over 2 weeks ago and havent heard anything from them (motorola). I also called the repair compainy and after not receaving any help from the lady that answered the phone so I ask to speak to the supervisor. I was transfer to the supervisors voice mail, so I left a message. And of course I have not received any communication from that supervisor eather. Don't know what else to do. Anybody haveing simuler problems? What did you do? Thanks Gregg
