Default [Q] Unlocking phone without using another carrier's SIM Card

Hi guys

I purchased a t-mobile mytouch 4g outright last week (no contract). When I contacted t-mobile about getting the phone unlocked, they were happy to provide me with an unlock code. The only problem for me is that unlocking the phone requires using a SIM card from other phone provider, something which I dont have access to atm. Is there any way for me to unlock the phone without having to use a SIM card from another provider. Buying a SIM card isnt cheap (eg $25 for AT&T SIM card), and I would like to get the phone unlocked before I head overseas (in case the unlock code doesn't actually work, I won't be able to return the phone to t-mobile without having some difficulties.

The only way you would be able to do that, that I know of would be to root it and do the s off procedure. I think that also will do the sim unlock for you too. Read over the method that uses gfree and visionary. I think it talks a little about the sim unlock and when in the process it occurs.

Maybe you could just go to att and ask them if they have a sim card you can pop in to complete the process.

borrow one if possible, or do the root method. Worked perfectly fine for me doing that method

First of all to correct True if you go that path you van manually do it via Radio S=OFF, since you have the code why go though all of that? Just do as Osu said and barrow any GSM based carriers SIM. This is another example of Android fail as WinMo has simlock.exe as toolkit for this very reason to unlock it without SIM card.

Is this a new process for unlocks from T-Mobile, that you need to have another provider's SIM card? If I recall correctly (dubious) from getting an unlock code for an MDA and an SDAseveral years ago they would just email you the unlock code and you would enter it into the phone.

Related question if I may: Does T-Mobile still give unlock codes to people who purchased a subsidized smartphone (in particular the MyTouch 4G)? I am considering buying three to replace aging original iPhones and a major reason for me sticking with T-Mobile over the years is their unlock policy. Just want to make sure it's not significantly different for smartphones.

Thanks ... Mike

If the phone is taken on a contract, I believe the unlock policy is that it can only be done after 90 days. I bought the phone without a contract outright, which is why I was able to get the unlock code within a week (although I had to call them up and argue a little).

With regards to the unlocking itself, from what I understand if the phone is not rooted (I don't wanna do it yet as I'd rather keep the warranty for the time being, at least while Im still in the US), then the only way it can be unlocked is with another carrier's SIM card because that is the only way that you get prompted to enter the code. I have a code available for my phone, it's just getting the damn card so I can actually unlock it.

btw Im currently in a country with no contacts who are with AT&T, so getting their SIM card is easier said than done. It costs 25 bucks to purchase a AT&T SIM, something I would rather not do to get the unlocking procedure done. From what I've experienced At&T is the only major provider aside from t-mobile which still uses SIM cards, and Boost mobile/Sprint cards won't work with regards to unlocking because they use a completely different type of network, so the phone can't even detect their SIM card (I tried a Boost SIM and it didn't work)

I just recently unlocked some of my older T-Mo phones to sell them more easily. They will provide you unlocks for a retail price phone in one week, or a contract subsidized phone in 90 days. You can even request unlocks for phones you no longer use (like my T-Mo Dash I found in a box in the garage).

To "complete" the unlock process you must insert a non-TMo SIM card and the device will prompt you for the code. After entering the code, the phone is unlocked and will remain that way. Borrow a friend's SIM, it's what I ended up doing. Alternatively, if you are just wanting to unlock to resell the phone later, the code is "always valid" for that phone's IMEI and you can just provide the next owner with the code.
