Best Answer

GSM-900 and GSM-1800 are used in most parts of the world: Europe, Middle East, Africa, Australia and most of Asia. In South and Central America the following countries use the following: : :* Costa Rica - GSM-1800 :* Brazil - GSM-850, 900 and 1800 :* Guatemala - GSM-850, GSM-900 and 1900 :* El Salvador - GSM-850, GSM-900 and 1900 GSM-900 uses 890-915 MHz to send information from the mobile station to the base station (uplink) and 935-960 MHz for the other direction (downlink), providing 124 RF channels (channel numbers 1 to 124) spaced at 200 kHz. Duplex spacing of 45 MHz is used. Guard bands 100 kHz wide are placed at either end of the range of frequencies[1]. : In some countries the GSM-900 band has been extended to cover a larger frequency range. This 'extended GSM', E-GSM, uses 880-915 MHz (uplink) and 925-960 MHz (downlink), adding 50 channels (channel numbers 975 to 1023 and 0) to the original GSM-900 band. The GSM specifications also describe 'railways GSM', GSM-R, which uses 876-915 MHz (uplink) and 921-960 MHz (downlink). Channel numbers 955 to 1023. GSM-R provides additional channels and specialized services for use by railway personnel. : All these variants are included in the GSM-900 specification. GSM-1800 uses 1710-1785 MHz to send information from the mobile station to the base tranceiver station (uplink) and 1805-1880 MHz for the other direction (downlink), providing 374 channels (channel numbers 512 to 885). Duplex spacing is 95 MHz. : GSM-1800 is also called DCS (Digital Cellular Service) in the United Kingdom, while being called PCS in Hong Kong[2] (not to mix up with GSM-1900 which is commonly called PCS in the rest of the world.)

Can you turn any phone into a tracfone?

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 a cell phone from telus Canada be used with a plan from bell Canada?

Yes and no. They both use the same technology (CDMA vs the GSM network used by Rogers and Fido), but handsets are sold locked to the network they are activated on. You can get it unlocked for a fee, but you'll likely have to find a third party to do it. Carriers rarely provide that service.


Will at and t not have the i phone once Verizon gets it?

I work for AT&T, and I can honestly tell you that AT&T will still continue to have the iPhone even when Verizon gets the iPhone. When Verizon gets the iphone:There are no differences between the phones except that Verizon's iPhone (on a CDMA network) doesn't support simultaneous voice and data as with the GSM version. So you can't surf the web while talking on the phone as you can on the AT&T network (There is no difference except Old Pacbell territories vs Old GTE territories for coverage. Verizon still uses old CDMA technology which only works in North America. AT&T's GSM works world wide) Verizon does have some GSM towers for the BlackBerry devices that run on that network and can be used as world phones but they are very limited tower amounts so the coverage for GSM service is very limited as well (this has been reported by many Verizon customers who use these BB devices-so the iPhone may have the same issue) There is no word on what data plans will be available or be required when Verizon gets the iPhone. Due to Verizon using the old CDMA network instead of GSM, world travel with iPhone may not be able to be used, but word on the will come later. As well no official word is out yet, but when Verizon gets the iPhone, Apple may still choose to limit the amount of free and .99 apps that they will provide to Verizon iPhone users. If this stands true, then you will be able to get more free and .99 apps with the iphone with AT&T than you would with Verizon. Granted no service provider is 100% perfect with there service.
