GSM Cellular Phone FAQs
What is GSM?
GSM (Global System for Mobile Communications) leads the world as the fastest growing, most reliable and advanced digital technology available in the marketplace today. GSM provides integrated voice mail, high-speed data, fax, paging and short message services capabilities. GSM customers enjoy secure communications, and GSM offers unparalleled call privacy and fraud prevention. As members of the GSM Global Network, GSM subscribers can use their phones at home, across town, across the continent, or around the world (except for with country specific SIM cards). GSM operates on the multiple spectrum frequency bands used around the world - 1900MHZ, which is used in North America and 900MHz and 1800 MHz for other locations. Different mobile phone networks operate at different frequencies, which means that if you wish to use your mobile phone outside your home country, you generally need a handset that supports multiple frequency bands. Make sure that the celluar phone you are interested in is compatible with the GSM band of the country you will use it in. As a general Guideline:
Dual-band - A dual-band phone operates at both the 900 MHz and 1800 MHz spectrum. Dual-band works in Europe, Africa, Asia, Australia, New Zealand and much of South America.
Tri-band - A tri-band phone operates on three frequency bands, 900 MHz, 1800 MHz and 1900 MHz, allowing you to use it in Europe, Africa, Asia, nearly all of North America, Australia and New Zealand.
Quad-band - A quad-band phone allows you to roam almost anywhere globally. It covers the 850 Mhz, 900 MHz, 1800 MHz and 1900 MHz frequency ranges. Many countries in South America only have 850 MHz GSM service while both 1900 MHZ and 850 MHz GSM services are supported in the USA. 99% of all countries use the GSM standard. WE believe eventually GSM will be the only cell phone standard in the world.
The GSM network provides the best digital wireless voice quality in the world today.
What is a SIM card?
The SIM (Subscriber Information Module) card - a.k.a. "smart card" - holds all of a subscriber's personal information and phone settings. In essence, it is the subscriber's authorization to use the network. It also holds the phone number, personal security key and other data necessary for the handset to function. The card can be switched from phone to phone, making the new phone receive all calls to the subscriber's number. For more information about SIM cards, go to our Prepaid SIM Card FAQs page.
Where in the world can I use my GSM phone?
At the end of 2000, the GSM Alliance had signed agreements with 217 international carriers representing more than 100 countries. GSM customers can use their phone service at most of the tourist destinations in the world including Europe, Asia (except for Japan and Korea), Africa, the Middle East, Australia, New Zealand, India, China and other countries and most major cities in the United States and Canada.
Will a 900MHz GSM phone work in the United States?
In most cases, no. 900MHz GSM services will work in Washington DC only. Since Washington DC is home to many foreign diplomats, special considerations have been given to the area. In the US, 1900 GSM service is available in most areas. Please be sure to check local carriers such as Voicestream or Cingular wireless to verify that there is coverage in your area.
What does unlocked mean?
Most cell phones that you would purchase are locked, meaning that you must use the provider's service for receiving phones calls. Since ours are unlocked, you can simply purchase the cell phone and purchase the SIM card elsewhere.
Are your GSM cell phones unlocked?
All our GSM mobile phones are FACTORY unlocked - they will work with any GSM SIM card from any country on earth - so you needn't be tied into any specific carrier or contract. Every time you change the SIM CARD the GSM phone becomes whatever the new SIM CARD is. I.E. a new telephone number, memory for credit, the ability to work in the new country etc.
If you got your CELL PHONE from a USA carrier (such as T-MOBILE, AT&T etc.) very likely it is LOCKED to their service and can't be used with any other service provider in the states or overseas. To determine if your phone is locked call your service provider and ask them. If they will not unlock it for you our phones are FACTORY UNLOCKED with all features always available, we rent and sell these phones. Often if your carrier will unlock your phone some of your phone's features are permanently disabled.
If you purchase a SIM CARD from us you will SAVE as much as 95% of what you can expect to pay for your outgoing calls through American companies such as Pacific Bell, AT&T, T-MOBILE, Cingular, GTE etc. For example, calling the states from England is just US 7 cents a minute. Incoming calls (from any and all countries on earth) are free for you to receive in 99% of all cases.

When will I get my phone number?
Unless indicated on the country specific web page, phone numbers are given when you purchase your SIM card. If you purchase an country specific SIM card, you will get an overseas number pertinent to that particular country. Swisscom international prepaid SIM cards have a Swiss phone number assigned to them.
What language do the instruction manuals come in?
Since GSM phones are intended for Europe, most do not include english language manuals. English language manuals can be downloaded from the manufacturers' web sites.
