Why my iPhone is detecting headphones?

I'm unable to play media audio because the volume setting is mysteriously linked to headphone mode. However, my ringtone and call audio still plays through my speakers.

How can I factory reset my family member's iPhone 5s?

My distant family member/relative recently passed away and she had an iPhone 5s that's still in good condition. Many already had an iPhone and didn't need an extra one, I did, so they passed it down to me.

Problem is I never knew what her pass code digits on the home screen were and neither did her immediate family.

So I'm curious, how do I easily get pass this?

Yes, I know I could just google it, but I just wanted to know in your opinion, what is the easiest way to do it? I'm asking because I've never been too tech savvy and wanted to know which way is the easiest.

Why is my unlocked iPhone X having trouble switching to a new network?

I recently bought an iPhone X off of ebay. The seller has been working with me through this trying to help me figure it out. The phone he sold me was an iPhone X replaced by the warranty plan he had, coming with all of the additional attachments in the box. It was unlocked by ATT and he said switching the sims with a non ATT sim worked for him. Worst case scenario he said he'd refund me so that's the fallback plan.

I recently brought it to Metro and everything went good at first but the only problem it had was connecting to any network. They told me just to double check it was unlocked so I checked with some paid IMEI checker and everything looks good. I feel like I'm missing something here and I'm hoping someone is more knowledgeable than me on this topic.

Thanks in advance guys!

Added (1). Okay just a tab bit more info: I contacted Apple customer service and they suggested the following…

I have yet to contact ATT myself but I will today.

I just recently updated the phone to IOS 12.2 which was not done before the first time I brought it.

Last time I was not told to turn off Find my Iphone

Added (2). another update:

I was trying to unlock it on ATT.com and I got this message: "Looks like the device you want to unlock is active on another AT&T account. The owner has to remove it from their account first." So I think I found my problem

Vodafone Simcard, I recently got a new IPhone XR and my brother got me a simcard from Vodafone, I put it into my phone but won't work?

Added (1). (i had no space in the inital queston) No matter what I do, it says no service and I do not have a number apparently. I sent messages to vodafones systems to give me a number and they all fail. I sent my sister a message and it came through as my gmail. I do not know what to do and it is very frustrating as I have just changed to Vodafone
