Can't set up voicemail on my iPhone 6 through straight talk?

I just purchase an iPhone 6 through Straight Talk. I went to go set up my voicemail, but I can't seem to access it at all, it keeps telling me it's unavailable at the moment. Is there anybody who knows how to do this and can explain or has half this same problem?

Anyone else regret getting the iPhone 6/6s in plus?

I'm starting to, I really liked it at first but now I'm seeing how inconvenient it can be. Its' hard to use it with just one hand when you have something else in your other one. I think I'll definitely be getting the normal size next.

How to get out of my Verizon edge agreement with a yr left?

I got the note 4 with Verizon back in November 2014… My phone OS updated to the lollipop update and it has been terrible ever since which has been since about April. I have gone though 6 replacements since November of last yr and they just want to send me more replacements after complaining. Service is not terrible which if because of the new OS phone restarts and it lags terribly. They told me if I pay so much I can upgrade to something else I owe 430 ish left on the phone and refuse to pay for something that does not work half of the time. Any suggestions or am I stuck with this phone for another yr? I have been thinking about trying the iPhone 6 and would also like opinions on that over android.

How to remove nail polish from my iPhone 5s?

I got a little bit of nail polish on the gray/metal (?) back of the phone. I don't want to test out nail polish remover before I know it's safe… I think it might ruin the phone itself. Any suggestions?

LOST IPHONE! Need advice please?

I lost my iPhone a day ago. It doesn't have actual data, just talk and text, and my carrier is AT&T. When I went on the 'Find iPhone' on my mom's phone, it says that my device is offline.

On the app 'Find Friends', it says that my phone is right at home, but I know for a fact that i lost it. Is that app accurate or no because I've tried that app like 20 times already and it still says it's at home. I already reported it to AT&T as a lost device but I'm not sure what that will do.

Is there anyway for someone to hack in?
If they do hack in, will I be able to trace it?

Added (1). Yea when it refreshes, it says '1 min ago' but on the app 'find iPhone', it says my device is offline. And if my phone was home, it would automatically connect to the Wi-Fi.
