I have an iPhone4 sim card problem. Any

Ok so i bought this second hand iphone4. The person didn't tell me much. The screen was cracked so i had it changed and they told me it won't read the sim card. I tried finding answers online but the thing is the iPhone isn't avtive. Needs to be activated with iTunes but in order to do so, it needs a sim card. But again it said "please insert a valid sim card" please help…

Does this sound unreasonable of my husband?

So my iPhone 5s broke, so I had to wait for a new phone, so now I don't have a simcard. I do have an old Samsung I'm using with Wi-Fi connection. So this morning my husband was late for work, because one of the cats I'm petsitting woke him up in the middle of the night.

So he had to order Lyft on his phone to get to his work in time. So he had to take his simcard and put it back into his phone (I borrowed it to make arrangements earlier)… So then he said "**** you can't call the dr then" because I need to make a medical exam appointment for adjustment of status (it's part of the process). So then he said to me that he won't have time to make an appointment at work and that I should skype call the doctor to make an appointment. He knows my computers microphone doesn't work and it's just a hassle. Making an appointment takes less than 2 minutes, he sometimes will share videos on FB during work hours, he has a lunch break too? He's a computer engineer. But still, do you think this is unreasonable?

Added (1). AND ALSO - HE is the one insisting that I make this appointment As soon as possible - I'm much more relaxed in terms of WHEN I see the doctor. But he's hassling me about it.

Added (2). No HE has his phone with the simcard. I have no simcard to call with.

How to get back my deleted music?

I recently deleted most of my music to save on storage, then I updated my iPhone 5s, and now the place in the settings where it said "show all music' where I could recover deleted music, is no longer there. I don't have a computer, so is there any way to get it back without using a PC?

Can't connect to facebook from my iPhone?

Recently I've had a problem with connecting to facebook from my iPhone. It doesn't connect through the app, or Facebook messenger, or Safari, or through other apps, and it happens on both Wi-Fi and data. Absolutely everything else works, it's just Facebook and it's frustrating.
