What's the difference between the numbers of Telecom 133 and 177?

133 is a 3G segment. You can change the card to 4G. If you don't want to change to 4G, you can continue to use 3G. You can't switch back to 3G after switching to 4G.

177 is the 4G segment, and the 4G function package is opened, but it cannot be changed to 3G.

133 refers to China Telecom Tianyi 133. In June 2008, China Telecom acquired the CDMA network of China Unicom with a huge sum of1100 billion yuan, which means that 43 million users of China Unicom starting with 133 and 153 will soon be served by China Telecom. Since March 9th, 20 12, China Telecom has been selling iPhone 4S to customers in China.

177, which is the 4g segment of China Telecom, has two kinds of packages, to be exact, three kinds.

One is the 4g package with fixed package options, such as 596979. Each package has a different set of contents.

There is also a pure traffic package, with only traffic, 4g, which is also section 177. The lowest seems to be 49.

The third is the "customized package" from 15. You can freely choose/combine voice/traffic/SMS, and the minimum consumption amount is 19 yuan.

177 belongs to China Telecom's 4g section, which was recently numbered.
