The choice between CDMA and GSM is a matter of personal preference. In general, the latter offers faster data download speeds, but CDMA is more secure. GSM’s EDGE technology, however, is subject to interferences. Therefore, you may wish to consider your own location when making the decision. Read on to find out more about the two different technologies and which one you should opt for. If you are unsure, you can always try them both to find out which one best suits your needs.
The differences between CDMA and GSM are not so obvious. While GSM and CDMA networks use SIM cards, the former is more flexible. SIM cards can be placed in either GSM or CDMA hardware. GSM phones have a SIM card slot, whereas CDMA phones do not. The latter offers better compatibility with CDMA handsets. Moreover, modern CDMA phones offer a SIM card slot, which means you can take advantage of 4G LTE capabilities.
CDMA uses a power control system that minimizes interference. EVDO (Evolution-Data Optimized) technology makes it possible for many users to share a single bandwidth. The two technologies use different techniques for data transmission, but both have their advantages and drawbacks. Those who choose GSM will find that it is more stable and better suited for outdoor usage. In contrast, CDMA devices have fewer frequencies.
