My can't connect to my Wi-Fi. How do I fix this?

This has been going on for a couple months now. But basically what happens is whenever I want to use the internet on my iphone, it will very often disconnect from the network. I thought it was just my phone but i found out today that my sister has been getting the problems aswell. Our internet should be top class, its what we paid for, and I wanna see if i can find a solution elsewhere before I go and call for support. How can I fix this?

An app that can add rectangle behind text?

I make Kpop confessions on Instagram and I want to change my edits to placing my text in a box. Anyone know any good free apps? Apps, not sites, because it's on my phone. Please Please Please help. 10 points to best answer. And don't say Phonto or GIMP. Phonto doesn't work properly for me because I'm Android so the edits aren't as good as the iPhone one.

I'm really scared it was a 600$ phone

Would my iphone be useful for anything if I sold it?

I have a gold ipone 5s that looks brand new. Just the one corner has a small dent in it. The icloud is not locked. The only problem with the phone is there's a hardware issue that is not fixable. It causes my iphone to restart multiple times a day and will sometimes go into a restarting loop for 5 minutes at the longest. It also will turn off sometimes that when I go to go on it I have to restart it. I was wondering if I could sell it on Ebay and get anything.

Why's my SIM card not working?

So I've just got my first ever phone, and it's an iPhone 5s. I put the sim in and set the phone up, turned it on, and it said it had no service. If I go into Settings - Phone - Number it says unknown. How do I get it to work?
