Does anyone know how to unlock a cell phone for.......
 

.........another cell phone provider?

I got a new cell phone and I sold my old phone to a kid. The phone is no longer under contract or anything, but I use Sprint and he wants to use Cingular for the phone he bought from me.

Does anyone here know how you unlock a phone to so it can be used by another cell phone service provider?

not all phones are interchangeable between companies I don't think

Open back cover, remove battery, remove simcard. Insert new simcard, replace battery, replace cover.

No simcard on the Sprint Treo 650 :(

Which is why I gave my response.

Damn man, mes likes yous, you are fast.....................:zzwhip

Okay I will look at it when I get home. The kid brought it home and I just got off the phone with him. I told him your response and he said the phone does not have two slots?!? :Hollering

Thank you for the advice and I will try it out when I get the phone in my hands. :thumbsup

LOL That is what Trace said! :winkwink:

GSM/GPRS model have this slot.

Sprint is CDMA and Cingular is GSM so that may be an issue.

If this is CMDA phone there is no sim card. Sorry for misleading.

A Sprint phone won't work on a Cingular network. Unlocking it will make no difference.

I give you one for free of charge .

Yeah you can't use a Sprint phone on any other network. They make them so you can't unlock it. No SIM card either. You're stuck with a CDMA phone. Sell it!

No problem thank you for responding so fast! :thumbsup

Yes I just realized this, thank you babe. I will make sure I put only Sprint users in the add. :thumbsup

Okay I will take you up on that offer! :winkwink:

my response was faster

This is the correct answer. :thumbsup

It would be easier for him to cancel his Cingular and go with Sprint.

depends if your on GSM or not

These guys have unlocked a couple phones for me. http://www.cellcorner.com/xshp/home.php :thumbsup

Verizon and Sprint are CDMA. No experience with taking a CDMA phone between carriers, just GSM..

T-mobile and Cingular are GSM as was pointed out.

I had Sprint for a couple years.. I think it's the sux0rs.

Would you happen to know how to make my canadian phone work with my US simcard when I'm in the US? **tried just switching the sim card and it don't work**
Rogers AT&T is the Canadian Carrier
T-Mobile is the US carrier

TexasDreams has a ban hammer!

*#*#1234#, then hit the Call button. you get a message that says SIM Unlocked. not sure if it will work for you as it unlocks the phone but not sure if it will do the the same for the carrier ID.

just ask someone at http://www.cellphoner.net - they are fuckintg crazy smart

-Turn the phone off

- while holding down 2, 6, 8, 3 and 5, turn the phone back on

-let phone completely boot up and then release the 6 and 5 keys only

-while still holding the 2, 3, and 8 keys down, press the 4 key 2 times and wait for a long tone followed by 2 short tones

- now release the '2' key and while still holding the 3 and 8 keys place your free hand on your head and spin around 4 times in a counter-clockwise direction (be careful not to spin clockwise, as this can damage the phone's internal memory, deleting all your speed dial numbers!!)

- LAST STEP : place phone in RIGHT SLOT of toaster (the one marked "single slice only") and with darkness setting on the SECOND LIGHTEST setting, engage the toaster and wait for it to pop back up ...

Your phone should now be unlocked, and it will no longer work on the Sprint network.

You need to get the phone unlocked. Some carriers will do it after you have been with them for a certain amount of time. For Cingular (one of my carriers) it is 3 months. Call up and tell them it is for foreign travel.

Otherwise you can pick up an unlocked gsm phone that can be used with any gsm system depending on the band of the phone. I did this for my business travel to Europe and before I knew carriers would unlock phones. Two good sources for unlocked phones are:

www.myworldphone.com & www.tigerdirect.com

As mentioned earlier there are also some online and offline companies that can unlock certain phones. Just do a search on Google. Good luck.

I read an article that they are changing the rules so you can use your cellphone with any provider.The way it is right now ,its glorified leasing.
