There are four categories of mobile networks commonly used by smartphone developers and carriers.



The Global System for Mobile Network is also known as GSM. More than a billion mobile phones are connected to this network around the world. AT&T and T-Mobile operate on GSM networks, as we mentioned above.


GPRS and EDGE are two more technologies incorporated into the GSM standard. With High-Speed Downlink Packet Access, abbreviated HSDPA, data can be transferred more quickly on 2G GSM networks.



A CDMA is a code division multiple access system. The technology has a greater capacity for data transmission than older mobile networks. A CDMA network is provided by Verizon Wireless and Sprint Nextel. It is called Evolution-Data Optimized or EV-DO for the 3G CDMA standard.



It is known as Long Term Evolution and is most commonly used in 4G networks. There are five generations of cellular technology available today, and the most recent one is 5G.



In the world of mobile technology, WiMAX is another newcomer. With this network, Sprint developed the first 4G network that competes with LTE.


HTC developed the first 4G phone with the Evo. Phones designed for the GSM network or those designed for the CDMA network aren’t normally compatible. Sprint and Verizon use CDMA networks in the USA, while AT&T and T-Mobile use GSM networks.


Unlike Ting, Ting utilizes a hybrid model. GSM and CDMA networks are both supported.
