There are two types of TracFones now, CDMA and GSM. This refers to the type of network used by the phone. And CDMA phone works only on CDMA networks, and same for GSM. GSM phones have SIM cards, CDMA do not (for the purpose of this discussion, anyway). I'm not clear on your reason for asking this question, but that's your answer. A CDMA phone does not have a SIM card. For more on CDMA vs. GSM Tracfones, check out this page: http://pbush14.wordpress.com/2008/03/16/tracfone-cdma-vs-gsm/ I should also clarify here that if your phone is a GSM phone, it MUST have a SIM card installed to operate. Also, to be used as a Tracfone, a phone must have the Tracfone software installed on it. This means that it must have been purchased as a "Tracfone" model. You can NOT bring a phone from a different service and use it as a Tracfone.
Can I use my tracfone in Aruba, if so is there a different charge?
No, only Motorola phones you buy from Tracfone can use their minutes.
yes just ask the company to move your # to your current phone
Straight Talk is an MVNO (Mobile Virtual Network Operator), which means that don't use their own towers - rather they "lease" service from a couple other of the nation's leading service providers. Tracfone wireless piggybacks on all four of the major carriers, depending on what phone you use. GSM: AT&T, T-Mobile CDMA:Verizon,Sprint
Tracfone is a MVNO (Mobile Vertual Network Operator) which is a fancy way to say they are a reseller. They buy minutes from Verizon and sell them to their customers. Tracfone is the oldest of the MVNOs. (They weren't even called that back then). Essentially, the network is the same but you pay a lot less on Tracfone's prepaid service. Verizon is a carrier using CDMA technology (as does Sprint). It is difficult to switch CDMA phones from one network to another. Its much easier on GSM which is the technology used by T-Mobile and AT&T. In fact, 95% of all networks in the world are GSM. The Bottom Line - You may be able to find a local Tracfone dealer who can "re-program" (hack) your Verizon phone to work on Tracfone. The main reason you'd want to do this is that Tracfone's service is really cheap but they offer only really crappy phones.
gsm
No u can't
No, you need to buy a Tracfone phone to use their service.
no.
Yes
TracFone uses both Verizon and AT&T's network to provide service to their customers. The network you have depends on your location.
