    I see a lot of reference to unlocked phones. I know this is a newbie stupid question, but what exactly does this mean?

    A security code is entered into the device to allow it to be used by any compatible carrier...all carriers restrict their phones from being used on carriers other then where they were bought from

    example: I live in canada, my carrier is rogers, but say i buy an AT&T phone off of ebay, if I unlock it, I have removed the restrictions from the devicetherfore allowing me to use it on my carrier.

    Review Here For Further Info

    So, I bought a Curve 8320 Titanium from LetsTalk.com and set it up on T-Mobile as a new subscriber. Once I received it I got my number from VerizonWireless ported over to the Curve.

    If I go ahead and unlock it will I be able to use VerizonWireless and AT&T networks since T-Mobile seems to be a bit spotty in my house?

    Corrrect me if I'm wrong, but you can't use T-Moblie/ATT phones on Verizon. They use different network. T-Mobile and ATT are GSM and Verizon is CDMA. You can only use unlocked phones on the same network. You can only use 8320 on ATT, T-Mobile, and other GSM (like Rogers). 8320 can't be use on Verizon.

    So, if I were to enter the unlock code into my 8320 then I should be able to use it on ATT network even though I am a T-Mobile subscriber?

    i went over to att from tmobile but kept my phone. when i out the sim card in from att it said invalid sim card, so today i found out that i need to unlock the phone. so when i called att, the rep called tmobile, tmobile stated that it will take 24hr to get a code for the phone. Is ther another way to get the code?

    Well Correct me if im wrong, but see i bought a Nokia 6133 the one with push flip button on the side from t-mobile and i call sprint to activated witht them, nd they couldnt so they told me that i had to call t-mobile and tell them to realease the ISM which means to unlock it and then they would be able to activated it for me and thats exactly what i did the only thing is that you have to wait about 24hrs to 7 buisness days for them to send you a email confirmation telling you how to do it with the phone with a code on it..

    Maybe I am missing something here. What you are saying is that even though I am a sprint customer, my phone can use other carriers network if it is unlocked. Does this mean if there is better coverage in my area that it will use that coverage? Do all the functions still work correctly? Sorry for all the questions but I am not as technical as most people here.

    I think you have to be a subscriber on that other network. It just means you can switch from one provider to another without getting a new phone PROVIDED they use the same technology - TDMA, CDMA or whatever.

    Yes you do need to unlock it but in your case you should approach your carrier and tell them that you are going abroad and they will do the unlock for you. Probably not for free but certainly cheaper than going to a commercila unlocker.

    Going abroad is the one valid exceuse to tell the carrier that you want the phone unlocked especially if you have a monthly contratct that you do not cancel.

    Let's try to get this straight.

    - The phone you got either works on GSM or CDMA. With a BlackBerry all phones except those ending in 30 are GSM (8110, 8120, 8300, 8310, 8800, etc.). The 8330 and the 8130 are CDMA. CDMA does not use a SIM card and CDMA phones are incompatible with GSM networks and vice versa.

    - Your phones came from a carrier who subsidised the price - you got it cheap in exchange for signing a term contract.

    - Subsidised phones are usally locked to the carrier to prevent you changing carriers or selling the phone on.

    - Unlocking is the process of removing the restriction of the phone only working with one single carrier. Once this is done a GSM phone can then be used with any other carrier worldwide.

    - With a BlackBerry the unlocking process requires a long number like this 66817178. This number is derived from your BlackBerry's IMEI and its PIN (Options, Status) and requires a good deal of processing to find. You need to find an unlocker. Here is one that I have used but in NO WAY endorse. I post it here purely for pricing reference WWW.UNLOCKTHATMOBILE.COM. Please do find your own unlocker.

    - I have an AT&T 8310 that I bought new off ebay. It was locked when I got it so I got it unlocked and now I use in on the Swisscom network. I take it to the UK where I put a different SIM card in and also to Spain where I do the same thing. It works perfectly AS A PHONE in all countries. I only have a data plan with Swisscom so I don't use data when abroad unless I put my Siwsscom card back. My son does the same thing when he travels to the US, China and elswhere.

    I hope this clears things up a bit.

    So the only advantage is that you can use the phone with other carriers? What about features that some carriers block and others allow. Does an unlocked phone allow you to user all the features of the phone?

    Thanks,

    Correct me if I'm wrong, my friend told me that for t-mo germany, they put hardcoded APN for their BB personal account (BIS). It prevents you to change your BB services let's say from t-mo to Att, because they put different setting. I haven't check it out because I don't have one. And does anyone has successful experience using unlocked BB and enjoy push email facilities through different network provider? pls enlighten me. Thanks

    GSM unlocking is sweet. Glad I don't really travel often out of the country if not I'd be out of luck on my sCurve.

    So if I unlock my phone

    I can use any carrrier's network that's in the area I'm in?

    Or unlock your phone means you can use different sim cards?

    And if its unlocked, do you still have to pay your carrier?

    Unlocking the device will allow you to use it on other GSM carriers.
