2. At present, the main reason that affects the speed and stability is signal coverage. If it is a big city like Beijing, Shanghai, Guangzhou, Shenzhen and Xiamen, the signal coverage of the three cities is good. It is recommended to consult the local business hall to choose which one is more cost-effective. (This is different all over the country, but most of them have an annual fee of 600~ 1000. )
3. If it is a small and medium-sized city, it is recommended to choose telecommunications. At present, in small and medium-sized cities, the signal coverage of telecommunications is the best. Because cdma2000 is upgraded from cdma, the telecom market and network deployment are the fastest.
Generally speaking, the wireless Internet access of China Mobile and China Unicom is limited in traffic, while the time of telecommunication is limited. So it depends on your application. If you spend a long time online, mainly browsing, email, chatting, fighting landlords, etc., and download less, then you still choose to move. If you spend less time online, but download more, then choose telecommunications.
Unicom is the least worthy choice at present. Although wcdma technology is good and the industrial chain is the most mature, it is a pity that China Unicom is too weak. If it is mobile WCDMA ... Unicom is the worst in coverage and service. Although wcdma technology itself is very good, at present, the strength of operators often determines the final market.
