Ok I have a really annoying problem I need help with. So whenever I'm at my house I have 1-3 signal bars but no symbol for the 4G LTE and when I try to use it I have no luck, I can't use the internet or make or recieve calls or messages. But whenever I'm not at my house I get the symbol and can start using my phone. Also I had an Iphone 5s previously and I had no problems using data or texting when I was at my house. So if anyone has something I could try it be really helpful, Thanks!
