How can I transfer my telephone #'s from one SIM card to another ? I am using different service providers.

There are sim card contact copiers available on eBay and through some cellular stores. A person at a T-Mobile store should be able to do that for you when you get your phone at no charge. I have one that I bought on eBay that's Nextel branded that works great. It works for copying other sims as well as Nextel sim card. I've copied T-Mobile to Nextel and back, as well as Nextel to Nextel and T-Mobile to T-Mobile.

sure, with a caveat. phones made for T-cellular or Cingular are locked to that variety, so once you're using a T-cellular pay as you go, you could't placed it in a cingular telephone and assume it to paintings. the finest thanks to get round it really is to get an similar variety telephone, purchase an unlocked telephone, or purchase a diverse variety telephone and get it unlocked. Unlocking regularly calls for a code, which commonly will be discovered with the help of Yahooing or Googling the phone variety. purely verify you'll discover the code earlier you purchase the phone - no matter if it really is not a extreme end telephone now and again human beings do not problem posting the codes. Verizon would not use SIM playing cards. Neither does sprint/Nextel - all 3 are CDMA. T-cellular and Cingular are GSM (and in many circumstances phones with SIM playing cards are GSM).

Yes you can do it. There is an article explaining how to do it on Dan Mobile's blog here is the link http://danmobile.blogspot.com/2007/04/moving-phone...
