Computer Help and Support

Phone problems could be (everything here is "could be" ) just old operating system and apps, namely safari.

You can upgrade the operating system only to ios 17. The phone can't support newer ones.

And presuming you are going through ATT only, you might try using wifi (if you have a computer, it's almost certain you have wi-fi. Only I use ethernet any more. I like it, but wi-fi for everything else, including the phone and tablets.

Can't help with the computer. There's just nothing like someone to look at things. I would visit friends and family to do so. It's extremely difficult to do any of this remotely (hence the "could be" ).

Perhaps there's a decent senior center which can give you a lead on someone nearby. Hopefully a friendly neighbor who will work for beer and burgers and not lots of money.

If you are in the CA Sierra foothills, I can drop by (not a windows person).

My family used to hand-down phones and laptops (to Mom, of course). I don't know if you can find decent stuff on Craig's List or other social media that I avoid.

Good luck,
I just wanted to mention some things that might or might not help.
