My IPhone 6 says no service, what should I do?

My iphone touch screen has been acting weird for a little while now. Sometimes it works, sometimes it doesn't. It usually gives me an issue in colder temperatures, it works better in warmer temps. Maybe like a month or so ago it started giving me issues with the service. I don't have a car right now and i work a lot so I haven't really been able to get to the apple store. The phone is also pretty bent. I know other people who's IPhone 6 is also pretty bent but it works fine. I have tried resetting it, I have cleaned the sim card and tray, I have looked for water damage but i don't think there's any but (I'm not sure what I'm looking for exactly in the SIM port), I have called apple support and they have ran diagnostics on it multiple times and everything shows up fine. My SIM card seems to be in fine shape. I don't know if I should purchase a new SIM card, for if that would be wasting my money. What could be wrong with it? Everything else works fine. It is not cracked. I can use it on Wi-Fi.

Prank calls from no callder ID on iPhone?

Iv been getting some calls from a "no caller ID" on my iPhone. When I answer I can hear someone breathing sometimes with a quiet tv in the back ground. They never speak. Iv been ignoring the calls today but they are becoming more recent. I called up my service provider and asked for a new number (my phone is contract) it's going to take a couple of days.
