Understanding Differences Between GSM And CDMA Cell Phones
In general, cell phone service providers typically choose one of two ways to give their customers service. That is, either having GSM or CDMA Cell Phones. What's the difference between the two you ask? What needs to be clear at this point is that different providers have different Radio technologies. For instance, Verizon Cell Phones use CDMA Technology and nothing else. However In the next few paragraphs we will tackle the question in more detail so that curious shoppers can make a better decision based on their needs.
Think of a cell phone strictly as an antenna. Different antennas work with different radio technologies, so before a company launches onto the mobile market, they decide a carrier. CDMA Cell Phones do not require a SIM (Subscriber Identity Module) Card while GSM does. This is good and bad for a CDMA based company like Verizon Cell Phones. They don't have to worry about customers losing their SIM Cards or even getting caught up in the debate as to what a SIM Card is. However SIM Cards do allow users to easily transfer information from an old phone to a new phone and so forth. And thus we begin to see the two sides of the debate.
CDMA technology, like Verizon Cell Phones, can hold more calls per channel on their towers than GSM towers can. If you've ever wondered what's up with all the "dropped call" commercials and such, this is the heart of the debate. It would seem that no one wants the lesser technology, which in this one case would be GSM, but it's really not that easy. And how many more dropped calls are there, anyway? Who knows for sure, but it is a point worth hearing.
CDMA Cell Phones don't always come out looking perfect, however. For example, GSM phones are used internationally, which means with little trouble, they can used when someone is in another country. But as one might have guessed, CDMA cell phones are strictly used in the domestic United States. This means when a user of these technologies is abroad, they will have to find another way of getting in touch with friends and loved ones.
As is the case with many things in life, there is not always a clean cut answer. While there are more differences, these are the big topics of debate which can help you find the phone and provider that fits your needs.
