How Come my Phone Does Not Work Oversea?

Ever wonder why your phone doesn't work in another country? Many countries use different cellular network infrastructure and a nice phone that works in one country may not work at all in another country. So, if you want a cell phone that works when you travel around the world you need to understand the basic technology behind cell phones.

Basically, there are two major wireless technologies that dominate the telecom industry - CDMA and GSM. Both have their own advantages work very well with voice and data. Majority of the European Asian countries have adopted GSM when cell phones were considered a luxury toy for wealthy and business executives. Today, most phones only work with one type of technology so that the cost of making the phone can be kept at minimum. However, phones that incorporated both GSM and CDMA are a bit more expensive and may require a different plan oversea. In the upcoming post, we will recommend a few world phones that will make your traveling oversea easy and fun.
