Samsung GSM Communications Cellular PhonesPlease note that the manual(s) included with the phones we sell may or may not be in English. You can download most manuals directly from the manufacturers' web page into English and other languages. Since all our GSM mobile phones are unlocked - they will work with any GSM 900, 1800, 1900 baud SIM card so that you needn't be tied into any specific contract. Click product images for more info.
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. All our cellular phones are unlocked and can be used by simply slipping in a SIM card. SIM cards for international roaming are available through GTE, AT&T, Cingular, Voicestream and others. These carriers will allow you to have a US phone number while you are abroad. However, their rates are often 3 to 5 times (or more!) more expensive than getting a pre paid SIM card for the country of your destination. Plus, the major providers have monthly service charges and sometimes set up fees. When you use a US carrier, you will pay for all incoming calls. With a pre paid calling card that you acquire overseas, you do not pay for incoming calls. If you obtain service and purchase or rent a cellular phone through one of the above mentioned carriers, please be advised that their phones are locked and you will not be able to switch carriers without purchasing a new phone. You should strongly consider getting a pre paid SIM card for these reasons and others. Pre paid cards are "rechargeable," that is, you can add money when and if you use up your air time. Most countries do allow you to receive calls even if your air time is expired. Other advantages of purchasing pre paid SIM cards, besides the savings, are that you avoid the hassle of credit checks and monthly bills and it's easier to control your expenditures.
