A:Answer Trac fones all have their own sim card. You are able to transfer your number and minutes from an existing phone to another Tracfone (yes, LG441G). You can follow directions that come with the phone, but I always call Tracfone customer number. They will walk you through any needed steps to accomplish this. Have your old serial number/sim number handy, or at the very least if you have your phone number you want transferred they can help you. The more info you have the better. Be prepared to listen closely to your representative, most likely will have fluent English but a heavy accent. They are patient, knowledgable, and very helpful.
