Can I pull out my SIM Card on my phone and put it in another phone and use it?

 

Yes in another phone that takes SIM cards. Phone may be branded to same service you use ie AT&T or T-Mobil. You can also unlock the phone or purchase on internet unlocked.

Need more info, ask more questions.

 

Welcome to the millennium...

 

Yea...the phone I have now is through t mobile...I want to put the sim card in a cingular phone that i have.

 

It won't allow you to use your t-mobile number on the At&T network...unless At&T phone is unlocked and can be used with t-mobile network.

G'luck.

 

ah..thats what i thought. Oh well..i will just buy a new phone. Thanks guys.

 

Also, the phone place can transfer all your data/presets from the T-mobile sim card to the replacement phone & sim card.

If you don't need to leave T-mobile but have a problem with the current phone, you can just buy a pre-paid phone from T-mobile and pop in your sim card rather than paying more for a replacement phone for the plan.

 

how do you unlock a phone?

 

Yes you can. We had AT&T and when they went out we got switched to suncom (small local service). Did not like them so me and my mom switched over to cingular (now AT&T again). Later we decided my sister needed a phone so instead of getting her a plan we just got her a sim card and put it into my moms old phone. It works fine and we where able to avoid signing up for a contract. At least try it before you waste your money.

 

Raheel is a vendor on AZ and does that for a nominal fee.

As I understand it, T-Mobile is either leasing or using part of AT&T/Cingular's GSM network, so unlocking one phone for use on the other network should be relatively simple.
However, I don't think that unlocking will permit a GSM phone to work with Verizon, Sprint, etc- CDMA or other non-GSM networks.

 

If you are up to the challange, depending on brand, you may be able to unlock it yourself. Do an internet search for sites that give you unlock codes.

As stated above you can also buy a T-Mo prepaid and swap in your card. Last, you can buy unlocked phones on the net. Any quad band GSM phone will work. If it's less than a quad band you must make sure it gets the correct frequencies.
