subject: What An International Cell Phone Is And Why You Need To Know [print this page] When traveling internationally, there are a few things that every traveler should have. A passport, of course, is essential, as well as a universal power converter. Also, because of the need for communications, an international cellphone should be packed for the journey. International cellphones, also known as world phones, are portable communication devices that allow for talk, data, or text throughout most of the world. Whether traveling on business or pleasure, it may be important to communicate with clients, the office, or home on occasions. A cellphone that can be used in most major cities internationally is more than a convenience.
It is important that the international traveler is aware of the differences between domestic and world cellphones. Domestic cellphones operate within the country and not as a world phone. Although calls can be made internationally from home as well as abroad, the caller will find that it can be very expensive. The international services are usually not automatic. Special plans must be arranged with the providing company for world talk, data, and text. International cellphones operate worldwide. Talk, data, or text can be made with no special plans in place. As a world phone, the calling plan already includes international destinations. Additionally, the Global Positioning System (GPS), translators, and maps are all accessible with an international cellphone.
World cellphones generally operate on one of two systems. Code Division Multiple Access (CDMA) is a service platform that may allow international phone calls. There are fewer countries that have this system in place than the GSM phones. CDMA phones are usually locked into one service provider. The Global System for Mobile Communications (GSM) platform is a cellphone network that is used more often throughout the world. It is the standard in Europe and many countries. There are well over two hundred countries that have the GSM platform as the standard in a cellphone network. GSM phones are unlocked meaning that they can be used in most regions throughout the world.
GSM cellphones use a Subscriber Identity Module (SIM) card which, essentially, is a computer chip. The SIM card can be placed in any GSM phone. With a SIM card installed in a GSM cellphone the user is not limited to a single provider or service. Global calls can be made without excessive roaming charges. With a service plan for international use for a provider with a locked cellphone, calls are rerouted back to the U.S. then to the call destination. An international cellphone will utilize the local GSM system, saving the caller many of the roaming charges. Therefore, the international cellphone is cheaper when placing calls.
Access to the Internet is very important when traveling abroad, particularly for the business user. With data capability, access to the Internet could not be easier worldwide. The talk, data, and text allow the world phone user to connect using any of the sources of communication and not meet a large roaming bill when they return home. Locked or unlocked cellphones are the options when it comes to global calls. The world traveler can save a lot of money on calls made to and from nearly any place in the world with an international cellphone.
