IPhone not vibrating when I get texts?

I have an iPhone SE that I got a little over a month ago, and for the past week or so I've been having issues with texts. I keep my phone on silent and set to vibrate when I get texts, but for some reason it's not vibrating every time that I get a text… Sometimes I won't know that I've gotten a text message until I look at my phone. It doesn't happen every time, just occasionally. How do I fix it?

Cases that would look good with space gray iPhone SE? - 1

What OtterBox cases would look good on the space gray iPhone SE? I know it's just a phone, but I'm 14 and I'm like this so all well. But anyway, if you know, can you please give me links to them? I bet you're thinking I'm rude for asking this but my taste is really not good… Thank you! <3

Shattered my iphone and now it won't turn on?

I got into an argument with my brother and he threw my phone, completely shattering the screen and lifting the camera and top speaker off of the base of the phone. Can this be fixed by a simple screen replacement? Is the LCD just loose, or is it worse?

Please allow 24 hours upon receipt of this notification to complete the unlock process?

I called AT&T to see if they could unlock my iPhone 6s and they told me they would send me an email with a code. I got the email 2 days later ( today ) however it said that I didn't need a code because the phone seemed to be unlocked already. Underneath that with the unlocking instructions it said the " allow 24 hours " message and I was just wondering if that meant that I had to follow and do the steps BEFORE the 24 hours passed or if it's AFTER the 24 hours have passed?

Is there any Danger in Sharing your IMEI Number off your Phone?

I'm selling my old iPhone as it's water damaged and just selling it for parts. Someone has requested to buy it and asked for the IMEI number. Just wondering if there's any danger in sharing this only through private message and also wondering why he would want it if the phone is broken.

How do i fix my iphone (its saying its disabled and needs to connect to itunes)?

I woke up and found it was disable for some reason. It says to connect to itunes. I tried but itunes says it can't connect the phone due to an error. And i gues iphone 7s don't have hard resets because i tried it and it doesn't work. I shut off the phone and when it comes back on it still says it. Why is my phone like this and how can i fix it? I've searched online but nothing seems to explain why this is or nothing i tried works.

Bought iphone at a thrift shop, has activation lock?

I got a iphone 4 at a thrift shop. When i restored it, it wouldn't let me use it because it has "Activation Lock" on it. I don't know who the original owners are, or how to find them so there's no way to find the apple ID. Is there anyway i can bypass it? I don't want to have a useless phone:/
