How can you stop your phone from being tracked down?

I'm going to leave home for a couple a days and staying with a friend till I can have some time to myself.am going to take my phone which has service and everything but I don't want my parents to track my phone down.im basically running away but I really don't want my parents to be able to track my phone down once I leave because I don't want to be with them. How can I prevent them from tracking my phone other then leaving it home. Its an iPhone 6s Plus.

My mum reckons she has the right to look through my phone?

I'm 23 and I still live with my mum and younger sister. I have a full-time job and an above average wage for my age. Earlier this year, my iPhone 6 died and I saved p for a new phone ever since. I finally had enough money for a new phone - so I bought the new iPhone X. It cost loads, but it was worth it. I also installed a SIM card and my number is different to my old one.

Ever since I've been using it, my mum expects me to give my phone to her once every day to see "if I haven't got into trouble". I think this is ridiculous - but she thinks I still need protecting. I think I'm too old to be need a parent's protection.

Does she has the right to look through my phone? Am I too old to be need a parent's protection?

Can you get a sim card from Dollar General that will work in an iphone 5s?

I have an iphone 5s that my friend gave me. I don't want data, just unlimited call and text like my old flip phone has. Can I achieve this by getting a sim card from Dollar General that only has call and text? If not, do you know of a way to work around this. My goal is to have the iphone with unlimited call and text without having to pay for data.
