    My family will travel to China this summer. A friend told me that if we "unlock" our cellphones, we can purchase sim cards and use the phones in China. So I called AT&T since I baught the phones along with the service contract from them. First the operator told me that AT&T has an international plan and I don't need to do anything with the phone for using it in China. However, I learned that it costs me $2.35 per minute. Assuming we use only 300 minutes per month, that's over $700! No, I just want to unlock the three phones so that I can use cheaper plan there. Then the operator asked me for "proof of purchase", I had to fax the receipt to AT&T. Why? I baught the phones from them and all three phones are active. Isn't verifying my date of birth/mother's maiden name/model of my first car/social security number enough to prove that I am the owner? Why didn't they ask for proof of purchase (or my permission) when locking my phones? Finally, I found the receipt. This time proof of purchase is no longer needed. I have to give them the three 15 digit serial numbers for my three phones. However, my phone still can't be unlocked. The operator opened a "task" for my request, someone from AT&T will call me in three days to get this resolved. I told the operator her management are idiots, she laughed, and almost said YES.

      Where I live unlocking is done for a few euros by the guys that repair phones. It only takes them a few seconds to do it. Easy money, what can I say... However, in theory doing so voids your warranty.

        That's a good suggestion. But I heard in China they have much fancier phones than in the US, cell phone is a symbol of status there.

          I'm not sure if the same where you are, but in the UK when you purchase a phone with a contract it is heavily subsidised, many times it will even be free. Sometimes there are even other things given away free with it too such as laptops / HD TVs etc.

          Thanks for your explanation. I think the point is, I am not trying to switch to a new plan, while in China I still have to pay the same monthly phone bill to AT&T regardless I use the service or not. I just don't want to pay for AT&T's international rate in China. $2.35 a minute? Give me a break.

          I agree totally - roaming costs are rediculous. If you can't get it unlocked... either buy a phone for use there before you go - or once you've arrived. You don't need anything all singing and dancing if it's only going to be used briefly. Get the cheapest piece of cr@p you can find, it'll be less likely to get stolen too! When you come home - take out the battery and stick it in a draw and it'll be ready for next time. Check out what frequency you need and the phone supports it if buying before you go - there are four GSM frequencies used (mainly) throughout the world: 850, 900, 1800 & 1900MHz. I beleive the US uses 1900MHz, Europe uses 900 and 1800...

            AT&T unlocked both mine and my daughters cell phones last summer with no problems. Had to provide the IMEI number and they emailed us when the unlocking was complete. We then purchased sim cards at the car phone warehouse in London and they worked perfectly. I think we were getting a 10p per minute rate to the US versus the $2+ a minute AT&T international roaming rate.

                    There are "base level" phones being sold for 15 EUR. No, they don't have the best technology, but they work. I had one of those as an emergency phone, placed in the glove compartment of my car. I'm pretty sure you can get one of those in China for even less. There even is another reason for buying a phone there: You need to check that your phones are of the multi-band type and that they can cover chinese frequencies. Otherwise they could be unusable in China - I don't know which frequencies they use, however.

                          I think when name is saved in session, the "unicodeness" is lost. If I type something and wait for the session to expire, then click "submit", my name will appear correctly. It is repeatable. Now, get back to work, Chris. :)
