yes, as long as the i wireless sim card fits!
Well, the sim card works just like any other sim card in a CINGULAR phone, but if you have the unlock codes to your other phone, I'm sure it will work.
Technically speaking, a Cingular phone can be used with T-Mobile, as you only need to switch the SIM card. However, the phone may be locked to Cingular, in which you need to unlock it to be used with another GSM network.
I have right wireless, its another service coming from the same company, i put my sim card into an LG phone, as long as it is a GSM and its unlocked, and also if it has CDMA then it WILL NOT work.
With Verizon Wireless, a prepaid phone needs to be on a prepaid plan for at least 6 months before it can be moved to a postpaid plan.
You can't put a SIM card on a Nextel Phone, since it's a CDMA carrier. The only carriers that use SIM cards are GSM ones, like AT&T, T Mobile, Centennial Wireless, etc.
Since Cingular is jointly owned by S.B.C. communications and Bell-South corporation, both companies put forward a total of forty-one billion dollars for AT&T.
At the current date(July 2009), you are not able to put Verizon Wireless Chaperon on an HTC phone.
install a wireless card on your laptop, and have wireless internet (via modem) in your home
As long as the Blackberry phone from T Mobile is already unlocked, then yes, you can use an AT&T SIM card on it, as well as SIM cards from many of the GSM providers worldwide.
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.
If the phone is from the same carrier then yes, it is very simple. If you were to try and put, for example, a T-Mobile SIM into a Cingular phone or vice versa, you will need to "Unlock the phone" first.
the only thing i would know you can do would be to use an sd card, and if you take off the back cover, you can put a mini sd card in your glyde.. hope that helps.
