What does the network format not supported mean?

The mobile phone does not support LTE, which means that the mobile phone hardware does not support the 4G network; 4G network is the fourth generation mobile communication network, and LTE (Long Term Evolution) is a 4G network standard; the mobile phone does not support this standard. So 4G network is not supported.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

1. The mobile phone does not support LTE, which means that the mobile phone hardware does not support the 4G network;

2. The 4G network is the fourth generation mobile communication network, and LTE (Long Term Evolution) is a 4G network standard;

3. The mobile phone does not support this standard, so it does not support 4G network.

The network standard is the type of network. The frequency bands commonly used by mobile phones in my country mainly include the CDMA1X and 800MHZ frequency bands occupied by CDMA mobile phones; the 900/1800/1900MHZ frequency bands occupied by GSM mobile phones; and the 900MHz frequency bands occupied by GSM1X dual-mode in the past two years. /1800MHZ frequency band; 900/1800/1900/2100MHz frequency band occupied by 3G.

The 2.5G (Generation) mobile communication technology that is currently in commercial application is a connectivity technology from 2G to 3G. It breaks through the constraints of 2G circuit switching technology on data transmission rate and introduces packet switching technology. This has resulted in a qualitative breakthrough in data transmission rate, and is a transitional technology between 2G and 3G.

The emergence of 2.5G is mainly due to the fact that 3G is a huge project involving many and complex levels. It is impossible to move from the current 2G to 3G immediately. Representatives include: GPRS, HSCSD, WAP, EDGE, Bluetooth, EPOC and other technologies.
