Sending text messages, surfing the Internet, making phone calls and Unicom are all cheaper.

As far as benefits are concerned, China Unicom is indeed cheaper. It is much more cost-effective to use SMS alone, and surfing the Internet is also cheap. For example, China Unicom has a prepaid phone bill activity here, which will be deposited in 30 yuan to send 50 million traffic for half a year. If you surf the internet frequently, you will be facing 5 yuan for half a year, but the speed of surfing the internet is really flattering. Many users can only use the 2005 version, others can't, they can only use 3G. If you surf the Internet frequently, you'd better use your mobile phone.

To put it bluntly, the cost of making a phone call is similar. If you send more messages, you can use Unicom, and if you surf the Internet, you can use mobile! !
