Will I lose my number if I switch from Android to an iPhone?

For some reason I can't find a straight answer to this question online.
Anyone who has made the switch from Android to an iPhone, did you lose your phone number?
I think this happened to my mother-in-law.

My husband wants to switch our plan and turn in our Androids for iPhones, but I don't want to do that if that means I lose my number. I have had my number for 8 years.

I was scammed online

Ok so I need help / advice.
I'm from the UK and I'm 18 and wanted some extra cash, so I decided to sell my old IPhone 6S that had a cracked screen, I went online and found a webiste that was verified and had good reviews, they told me they would buy it for £60 including them paying for shipping fees and that the money would be in my account within 2 weeks. So everything was fine, I posted my phone. Fast forward about 1 month and still no money or any emails? Then fast forward 2 months and still nothing? So i decided to email them and turns out there's only one guy that replies to the emails called Will. So i asked what happened and he was acting like they never bought anything from me. Bear in mind I never received a confirmation email so i litreally had NO proof. Apart from the receipt number that the lady gave me when I posted my phone. So it went back and forth with him and after about 3 months he contacted hermes and told me they lost my package and they can give you £20 in compensation. I ALSO contacted hermes and they said he received the package. Its been about 6 months now and still I always email him and he just does not reply to me, hermes in the UK is so **** too, I tried contacting them on twitter and they don't reply, originally i contacted them on some live chat service and now i can't even find it, and even then its people who don't speakers good english trying to assist me which is very frustrating, should I call the police or take him to court or speak to a lawyer?

IPhone XS Max Dock Holding Handle/Holder/Chuck/Stick/Boom

I have been wondering if anyone knows if there exists anything like a handle, holder, chuck, stick or boom for holding iPhone XS Max that you would plug into the iPhone XS Max charging dock like a USB dongle? I would like to use it for purposes like taking pictures with the phone, which would be more convenient for me than a standard selfie stick. Alternatively, it could embrace the phone at both of its lateral sides, and not be dedicated for plugging it into the USB dock, or be attached to the sides or the bottom of the phone in yet some other way. It would be best if this stick wasn't too long but of a medium length, or at least if its length could be regulated (i.e. If it could be either shortened or extended in length).

I would appreciate any recommendations or suggestions

My niece has an older iphone 4 phone. It won't let her download anything?

Added (1). It won't let her download anything. Whenever she tries it says…(This application requires ios 10.0 or later.) But when I check for updates it says…(ios 9.3.5 Your software is up to date.) How can I fix this? Or can I.

Why doesn't my IPhone make sound?

I don't have "do not disturb" on, airplane mode is off, I went into the settings and made it so literally everything should be making noise when anything happens, I don't have any "silent times" set. The only thing I haven't tried for it to make sound is throwing it at a wall.
