Should I sell my old phone?

I had a iPhone 6s rose gold 128gb and now got the new iPhone 8 plus and not sure if I should sell the 6s or keep for back up? And if I sell. How much for?

You can get $300 for it if you traded it in.

I would buy it for $170

No

  • What should I do should I get a new phone or not be embarrassed? And how do I convince my parents to get me a new phone? I have an iPhone 4 and it is 2017. The iPhone 7 already came out and I jane a 4. I feel really embarrassed when I take out my phone that I don't take it out because my friends have the iPhone 6 and 7.
  • Should I sell my phone? I have a Huawei p30 lite that I got a few months ago, but I rarely use it. I mostly use my iPhone. To be honest, the only time my huawei phone is used is when i want to download and watch netflix, since it had a bigger screen. Now, the only catch is that I would be selling it online for around half its retail price, because I don't want to go through the hassle of kijiji or craigslist. Should I go for it, or keep it?
  • Should I sell my phone to buy one second handed? So, I've had my iPhone 6 for a few years and it still works okay apart from the battery, but I can get that fixed for $30 so whatever. But then again, I could sell it online for 175 and buy an iPhone 6s for that same price. But second handed. The thing is, I'm not sure if I should. I really want a new phone but what if I buy one and there's something wrong with it? Should I just take the risk or stick with my old one?
  • Phone still rings on my old phone, what should I do? I just transferred all of my data from my android phone to an IPhone, and it was successful. But when someone calls me, it still rings on my old phone.
