What is GSM Mobile Wireless Service?

An International cell phone is classified as a GSM cell phone that operates on the GSM 900/1800 frequency. An international mobile phone with the appropriate SIM card will provide coverage in Europe, Asia, Africa and the Pacific Rim (including Australia). A world cell phone with the GSM 1900 frequency will expand coverage to include the United States, Canada and a growing part of South America.

GSM (Global System for Mobile Communications) is the world's leading cell phone standard, which was first adopted in Europe and then spread throughout Asia, Africa and the Pacific Rim (Australia, N. Zealand, etc.). This explains why the same cell phone that works in London also works in Johannesburg, Beijing and Sydney. The United States however did not standardize and it was left to the competing mobile services carriers to create whatever standard they wished. This explains why many US international travelers have a hard time getting wireless coverage when they are overseas and paying $1-$7/minute. A typical cell phone in North America is not capable of service outside of North America.

Prepaid SIM cards will help you stay connected while avoiding high roaming charges associated with taking your domestic GSM cell phone abroad. Learn more about SIM cards for mobile phones.
