Why does my iphone 5 not work?

Like where my data says LTE, sometimes it will go to 3G or like a small circle, and it won't connect to the Internet. Anybody know why? I have an iPhone 5, with Verizon

The NSA has control of your phone, and is watching every move you make, as well as every site you've viewed & text you sent
