4G as the future mobile terminal royal network protocol, its network speed is absolutely faster than you have not experienced the 4G network speed. And for those who have experienced the 4G network, it must be unforgettable. Unfortunately, many mobile phones in the past didn't support 4G protocol, especially Samsung's mobile phones. The update speed is too fast. The S4, which has been on the market for only one year, doesn't support 4G network, which makes Samsung users hate to say. Apple, on the other hand, is more responsible. You can easily enjoy 4G network with iPhone 5S through app.
The name of this app is Unicom 4G assistant, you just need to install the app, and simple settings, you can enjoy the 4G network. What's more exciting is that the app also enables iPhone 5 to support 4G networks.
