Each mobile device works on the wireless network and these networks are divided into different category such as 2G, 3G, 4G further they are subdivided into the category like GSM, UMTS, LTE on different bands.
GSM / UMTS / LTE / 5G
2G Network Bands
2G stands for the second-generation wireless telephone network.It works on Standard like GSM, D-AMPS, PDC.2G Networks supports Digital voice services and slow data transmission (2.5G (GPRS) or 2.75G (EDGE) ) but these networks are faster than analog (1G) systems.
GSM 850 MHz (B5), GSM 900 MHz (B8), GSM 1800 MHz (B3), GSM 1900 MHz (B2)
CDMA 800 MHz (BC0), CDMA 1900 MHz (BC1)
3G Network Bands
3G stands for the third generation wireless telephone network in compare of 2G it supports faster data speed, always-on data access, better voice transmission capacity.UMTS,WCDMA, Ev-Do are the main standard of 3G technology.
TD-SCDMA : 1880 - 1920 MHz
TD-SCDMA : 2010 - 2025 MHz
W-CDMA 850 MHz (B5), W-CDMA 900 MHz (B8), W-CDMA 1700 MHz (B4), W-CDMA 1900 MHz (B2), W-CDMA 2100 MHz (B1)
4G Network Bands
4G stands for the fourth generation of wireless telephone network it is more efficient and faster in terms of data rate, voice transmission and it is very different technology in compare of 3G.The most common standard are LTE (Long Term Evolution) and Mobile WiMAX.
LTE-FDD 700 MHz (B12), LTE-FDD 700 MHz (B17), LTE-FDD 800 MHz (B20), LTE-FDD 850 MHz (B5), LTE-FDD 850 MHz (B18), LTE-FDD 850 MHz (B19), LTE-FDD 850 MHz (B26), LTE-FDD 900 MHz (B8), LTE-FDD 1700 MHz (B4), LTE-FDD 1800 MHz (B3), LTE-FDD 1900 MHz (B2), LTE-FDD 1900 MHz (B25), LTE-FDD 2100 MHz (B1), LTE-FDD 2600 MHz (B7), LTE-TDD 1900 MHz (B39), LTE-TDD 2000 MHz (B34), LTE-TDD 2300 MHz (B40), LTE-TDD 2500 MHz (B41), LTE-TDD 2600 MHz (B38)
5G Network Bands
5G network and Its Supportive Bands
5G Band: 1(2100), 3(1800), 41(2500), 77(3700), 78(3500), 79(4700); SA/NSA
SIM Card Type
SIM stands for Subscriber Identity Module which securely stores subscriber's information such as phone numbers and text messages. Users can easily switch SIM card from one mobile set to another. SIM card is responsible for communication among several mobile devices using different kinds of networks such as GSM, UMTS, LTE etc.
