    Default Unlock question

    I currently use the thrive on att network. Is it possible to use this phone with t mobile? And if so do i need to buy a unlock code or can I flash a rom that already makes it unlocked for any network?

    There is a chance you can convince att to give it to you .but other wise you need to buy it.
    I dont know what you would need to say. But I presume that it would
    Be that your going somewhere that doesn't have att service.
    Good luck. Give feedback if you get att to give it to you.

    Ok here is what you need to do to get AT&T to release the phone. First you will have to have it long enough to cover the cost of the phone in AT&T's eyes. Next call them and tell them you want to use your phone overseas and your not sure how it all works and you want to make sure your phone is unlocked so you dont get screw having to buy a new phone when you get there. They will tell you that you can just use the phone like normal over there. But tell them it will cost you a fortune to do that and it will be way cheaper for you to just get service from a local provider. They should be willing to unlock the phone if they aren't, call back and try again eventually you will find someone that will... the other option is to tell them your giving the phone to a friend and they dont want to use AT&T. Once the phone is unlocked though you may have some issue getting it to work on the new provider there are some configuration that needs done. I'm getting ready to do the same thing soon if I can figure it out I will let you know how it works if you figure it out please post it somewhere to help the rest of us.

    Maybe depends on where your are at ... a lot of T mobiles 3g towers use different technology from AT&T so you can't actually run 3g ... I would check into this more before you commit personally I would try to get it to work with straight talk. it actually uses AT&Ts towers but it cost 45$ for unlimited everything.

    Did you go to T-Mobile or Simple Mobile? I can upload apn's for both tonight if you'd like.

    I went to a unlock website i dont remember exact url. They sent me a code that unlocked my phone. I was more curious for t mobiles because of the whole unlimited data for 30 that is a price range close to what my current plan is which is 25$

    I switched from AT&T to Simple Mobile. And like you, I was on AT&T's $25 plan, but with Simple Mobile for $40, flat $40 and no tax, I get unlimited everything. I did end up changing phones tho. Anyway since Simple Mobile uses T-Mobile towers, I have APN's for both.

    APN for T-MOBILE ::->
    Name: T-Mobile US or T-Mobile GPRS
    APN: epc.tmobile.com
    Server: *
    MMSC:
    MCC: 310
    MNC: 260
    APN type: default,supl,mms
    APN protocol: IPv4/IPv6

    All other fields left blank or unset. Hope this helps.

    It should, no guarantees tho. As I stated previously, I own a P506, but I ended up buying a P509 to use with Simple Mobile, mainly because I don't do credit cards, so I couldn't pay for an online service to unlock the phone from AT&T.

    As I said before it depending on where you are in the country. T-Mobile will not work in 3G mode with the LG P505 or P506 in most cases. T-Mobile uses a AWS on 1.7ghz in most of their towers. AT&T uses PCS on 1.9ghz. These are two totally different frequencies and two totally different data formats. Simply put it will not work.


    (AT&T) LG Phoenix / Thrive uses the following frequencies.
    GSM: 850, 900, 1800, 1900 MHz
    UMTS: 850, 1900, 2100 MHz
    As an example here is another Optimus one clone that was release by T-Mobile compared to the P505/506
    (T-Mobile) LG Optimus T
    GSM: 850, 900, 1800, 1900 MHz
    UMTS: 1700/2100, 2100 MHz

    So to put it another way your radio can't pick up the frequency it needs to talk to the Tmobile towers in 3G nor would it know how if it did... EDGE will still work but you will not be able to get 3G unless you are lucky enough to live in areas where T-Mobile has already converted there towers over to support the 1900mhz. I tried doing the same thing a while back with one of T-Mobiles HTC G1's and could not get it to work after hours of trying everything I finally figure out that the radio just didn't support it. This is the same deal only in reverse. Good luck to you but your probably barking up the wrong tree here.

    Is there any way to flash the Optimus T radio on the Phoenix?
