Can I take the sim card out of my existing cingular phone and put it in another cell phone and have it work?

Answer 1

absolutly if it is the same carrier

Answer

Yes, some new phones may warn you that you're not using the original sim card, but disregard that and you're ok. there's no reason why not.

Answer 2

Yes: As long as you have another Cingular cellular phone, that uses the GSM technology, there is no problem* (the Apple iPhone is an exception to the rule).

Your SIM card is your "phone", the single object that provides celluar service service to you. The physical phone is simply a device. Without the SIM card, it's useless.

Cingular, now the New AT&T, uses the most common network in the world, called GSM (Global System for Mobile Communications), which is used in approximately 70% of the world. Therefore, essentially, you can put a Cingular SIM card into any GSM phone.*

* There are some stipulations that can alter this answer.

Answer 3

No you cannot, but you can use it in an UNLOCKED T-Mobile phone. Cingular and T-Mobile work off the same network which is GSM and this allows you to switch phones. I have T-mobile but the phone I am using right now is an unlocked cingulart phone. Nextel/Sprint and Verizon work off of the CDMA network and this is why you cannot use it.

Answer 4

When you have a sim card most times you just pop out your sim card and put in any other phone. So I would say yes you can as long as it's not CDMA ( no sim card ) you will be fine.

Answer 5

No, you cannot. T-Mobile SIM cards only with T-Mobile phones. The same goes for an AT&T or Nextel SIM card, they only work for AT&T or Nextel phones, respectively.

Answer 6

Yes, but make sure it's a at&t pay as you go phone. I did it when my good phone died.

Answer 7

Yes you can, but when you put it in, make sure that the silver squares on the back dont get scratched on the conector or it might explode. Don't learn the hard way....

Answer 8

most likely, expessially if its with the same company as your phone is. For example if you are a verison try to place your sim card with another verison phone.

Answer 9

It will work as your existing phone.
