With nearly 30 Siemens GSM phones on the market in the United States, you've got a good choice of models to choose from. You want to check the specifications carefully on the frequency capabilities, however. Siemens GSM phones come in dual, tri-, and quad-band. Tri-band is always a good bet. The fact is, however, dual may be more than adequate for your needs--but more on that in a minute.

To put the company Siemens into perspective, its mobile component ranks number two in European market. It is one of the world's significant manufacturers of digital wireless telephone products for the consumer market. Ever since Werner Siemens (later raised to the short-lived German nobility for his achievements) hit upon a way to improve on the telegraph in 1847, the engineering genius of the company has been unmistakable. Let's get back to the frequency bands of Siemens GSM phones, however.

When the European community was developing its standard for wireless mobile technology in 1985, it settled on two specifications. One was that the frequencies used would be 900 MHz and 1800 MHz. Another was that service would be provided through a SIM (subscriber identification module) chipset that could be readily moved from phone to phone or replaced--just as with license plates in the United States. This standard spread to Africa, Asia, and the Pacific Rim. American GSM networks used a different frequency, 1900 MHz, and two additional technologies.

Highlighting Siemens GSM Phones

In sum, U.S. phones were useless anywhere else in the world. Other phones could not be used here. Among the Siemens phones manufactured to accommodate this situation are the small and sleek tri-band CF63 flip phone offered by T-mobile and the SX1 smart phone with Bluetooth, advanced display, and integrated still and video camera. Happy shopping!
