My phone is hacked. How do I fix it?

I kept getting notifications on my iphone 6s+ that people all around the world from Brazil to Zimbabwe were trying to sign into my apple ID.
So of course I changed the password. But even after changing the password and forcing them to sign out, they were still accessing my account.
I have thousands of photos and songs saved on it, so I would prefer not to do a clean wipe. Any advice?
(I also tried to install the Norton app. )

Does it matter which cell phone carrier I get if I don't plan to have a SIM card?

When buying a new iPhone I see ones that are unlocked for AT&T and ones unlocked for ones like Verizon or Sprint. If I don't have an cellular plan or SIM card, does it matter which one I get if I'm planning on just using Wi-Fi Calling apps. I could get a fully unlocked one but I don't know if that matters and they are harder to find

How do I get a SIM card for someone?

I want to buy someone a new iPhone, but they said they didn't have a SIM card or a carrier I guess on their old iPhone.

Will I have to buy a data plan or something from a carrier?
Sorry I don't know much about phones and sims and all.

Did anyone see the new iphone 11 pro trailer?

So it turns out that the Iphone 11 pro has the fastest chip ever in a smart phone which is the a13 bionic chip. It has 5 extra hours added to the batter life and has new ultra wide camera features. It also has an night mode feature where you can take photos at night and it's more visible than any other Iphone created. This phone shoots 4k 60fps in recording. This is the greatest phone of all time period. Androids fan boys can't say nothing anymore and if they do they're just in denial.

Why is iPhone XS Max suddenly losing sounds while in sleep mode?

It occurs about 3 times a week. More frequently when the iphone is in airplane mode or the Wi-Fi is off. I have tried resetting all configurations and deleting, restarting with iTunes, updating but the issue reappears. I took it to the authorized Apple technical service in Colombia, but they didn't find any problem. Has anyone else had this problem or knows about it? What can I do?
