Sim Unlocking

Any one knows when will there be a program that unlocks Excalibur, t-mobile dash... ? or does any one know where i can get my t-mobile dash unlock?. I am an AT&T custumer, i lost my tilt and because at&t does not offer insurance for these expensive devices i have to use my sister's t-mobile dash... but obviously its locked to t-mobile... Any help is greatly appreciated.
give you IMEI to a tmobile customer who has been with them for more than 2 months, ask them to ask tmobile for an unlock code.

Didn't I answer this exact question like 2 weeks ago???
This exact question from the same exact person, in fact.
huh? well are you guys gonna help me or what lol a week ago i aint have the code now i do so can you guys help or what?
You do not need an international sim card. You do need a sim card from another carrier. When you put the sim card from another carrier in the phone, it will ask you for a code. Enter the code from tmobile. This will unlock your phone.
Currently, your phone will only work with tmobile network. An unlock phone can be use with any GSM carrier. This is useful when you travel internationally. You can buy a prepaid sim card and use your phone to make calls.

[Q] Selling Note 2 - What to do with Unlock Code?

I recently paid off my Note II in full and I am ready to sell it. I am a bit confused about the unlocking process, so I was hoping someone could point me in the right direction.
I've put the unlock code request in with T-Mobile. Once I receive the e-mail with the code, what do I do with it if I want to sell the device? Do I put it up on Ebay and say "Comes with unlock code", or is there a way I can unlock it myself to sell?
I ask this, because from what I see, I have to put a different carrier's SIM in the phone to unlock it. Since I only use T-Mobile, I don't have another SIM. I looked on Ebay and I see a lot of TMobile Note 2's that already come unlocked, so I guess I am wondering how I can offer a pre-unlocked phone without manually shipping them the code to do it themselves. I don't want to have any questions about me trying to cheat any buyer.
Any tips would be appreciated. Search function is down, or else I would have used that first.
Or should I not worry about it at all and let the buyer deal with the unlocking? The phone has zero account issues.

Get a friends sim card and unlock the phone. Take a screen shot of it working with att and tmo and post both pics so the buyer is reassured that its actually unlocked. Once u unlock it, put ur tmo sim back in. It should work fine.

So the unlock isn't restricted to the SIM? Once it's unlocked, it's then free and clear to use any sim you throw at it without needing the code?

An IMEI unlock is permanent , similar to buying a " factory unlocked" device. Once its complete find a friend with a SimpleMobile ot ATT micro sim and take photos of the phone on both carriers and list it for sale.
Awesome. Thanks for the help!

bought a tmobile sm-n900t note 3 for a Christmas present and come to find out there is money owed on it, its NOT STOLEN!!!. I have no tmobile sim card either. is there a sim UNLOCK program I can use or can I do a phone unlock or use a root program? if this helps it runs android version 4.4.2...... build number??? n900tuvucnb4....I didn't want to use tmobile for service as I have everyone on h20 service. but when I took it in the guy said it had to have a sim unlock code hence the reasons I ask about programs. thank you for your help....happy new year!!!

unlocking note 4 question

Hey guys just purchased a code from cellunlocker.net and was wondering can I still unlock the phone if I don't have a foreign sim card? Just switched to Verizon so I no longer have service in the ATT sim. Is there a way to manually bring up the screen where you input the code?

The best way to unlock any samsung device is by inserting a foreign sim card.
Just letting you know, AT&T phone's are known to not work with Sprint or Verizon. Let me know if I am wrong but this is the strong consensus.
This is because Verizon is CDMA based while AT&t and other carriers around the world are GSM.
Just a heads up
