What is a "2g 3g Mobile"? The Most Authoritative Explanation.

Why do 2G and 3G networks use the same frequency bands?

And 3G networks use bands between 850–1900 MHz or 900–2100 MHz. More advanced cellular technologies could use these same bands to provide higher data throughput and more valuable functionality. And all around the world, the opportunity these newer networks present is outgrowing the demand for continuing to support 2G and 3G infrastructure.

What is 3G mobile network?

Third Generation (3G) : 3G mobile network was developed in Japan in 2001 to achieve heights of speed which was lacking in 2G technology. The standards of this technology was set by International Telecommunication Union (ITU). This technology provided users with services like GPS (Global Positioning System), video conferencing and mobile television.

What is the frequency range of 2G network?

2G networks : 900 MHz (band 8) and 1800 MHz (band 3). 3G connections : 900 MHz and 2100 MHz (band 1 and 39). 4G networks : 800 MHz (band 20), 1800 MHz and 2600 MHz (band 7 and 38). 5G connections : 700 MHz (band 28) and 3500 MHz (band 78).

What happened to 2G and 3G cell phone networks?

Some carriers have already sunsetted their 2G and 3G networks, pulling the plug to make room for newer cellular networks like 4G and 5G. Most other operators have at least made plans to shut them down. Thankfully, they’ve made these plans public—so you won't be caught unaware.
