The most popular GSM carriers are T-Mobile and AT&T. If you buy a CDMA device that does not have a slot for a SIM card, you will not be able to change to another network should the need arise without buying a new device, and you will likely not be able to use your device if you travel internationally. When purchasing a mobile device, such as a mobile hotspot, tablet with cellular capabilities, or smartphone, check whether it is CDMA or GSM. GSM networks are more widely used on an international scale than CDMA.Īnother key difference is that GSM networks use SIM cards while CDMA networks do not require a SIM since the hardware is built specifically for the CDMA network (though devices built to be on an LTE network will have a SIM regardless). CDMA and GSM differ in how the device connects to the carrier, how voice data is transmitted, the level of coverage, security, and other factors. These competing technologies are used by different carriers and devices. The two global standards for delivering mobile broadband service to a device are technologies known as CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles). What technologies are used for mobile broadband in the USA? Contracts are also included and may require early termination fees for ending service prematurely.

LTE stands for “Long Term Evolution,” signifying that mobile broadband standards are continually evolving every year. Despite the recent emergence of 5G, 4G LTE is still the current standard used on most smartphone plans. Mobile or cellular broadband can be broadly categorized into four categories: 2G, 3G, 4G, and 5G. It is expected that 5G technology may offer speed and performance that could match or even exceed wired broadband services.įor more technical specs on mobile Broadband technology, see our guide to Mobile Broadband Internet. While coverage is still very limited, it will expand across the nation. For example, streaming and other activities that demand high speed and large amounts of data are not recommended on mobile networks, which often place small data caps on users to limit network congestion.Īs of 2020, all four of the biggest mobile broadband providers in the United States have launched 5G services.
