IPhone internet service?

First off I'm 61 and dumb about cell & the net. I have an iPhone 6. Right now I'm on a plan with AT&T for 50.00 a month for cell and internet. Kinda hard to afford. No computer. Is there a better deal out there for me and my iPhone 6.

Walmart offers economy plans from a number of providers.

  • Why does my service/internet stop working on my iPhone? I have had an iPhone 4s for 2 years, and never had any problems until the last few days. I can't text, call, or do aything that involves my 4g service. I have to turn off my iphone completely and then turn it back on. Sometimes I have to do this 4 or 5 times until i can text/get on internet. And when it does finnaly work, it will only last for about 5 minutes. Then I have to restart it again. This is very annoying and what can i do to fix this?
