Snapchat won't connect?

I recently moved to Japan had to get an Iphone and I went to sign in and it says "can't connect" I have Wi-Fi and Data so it should be able to connect. I have tried resetting connection settings, redownloading the app, and also deleting the apps cache.

IPhone 6 with no SIM card?

So I recently bought an IPhone 6 from OfferUp. I checked the IMEI and it hasn't been reported lost or stolen. So I want to turn the phone on. There's a MetroPcs store near me. I thought I'd ask here before I go into the store. Will Metro Pcs be able to turn on my IPhone? Of course I need a SIM card. Would they be able to provide me with card as well?

All of the pictures on my iPhone disappeared

Ok so a few moment ago I was on Snapchat watching someone's story when it stopped and gave me a notification that my phone storage was too full. I keep a lot (and I do mean A LOT) of photos on my phone, so I went there and started to delete a few. Well in the process of deleting them, my phone suddenly restarts by itself, and when I try to go back to the photos app, literally EVERY picture is gone. Nothing else on my phone is missing; I have al my notes, apps, music, etc. But my pictures are gone. Those pictures are very very important to me and it would mean the world to me if someone could help me figure out how to get them back.

If it helps any, I have an iPhone 5s with iOS 9.2
And most of my photos were not backed up on iCloud due to me having so many and running out of storage.

My mom tracks my iphone, how do I avoid it?

She uses xfi locator. Lately i've been lying where i'm at even though I know she tracks me lol. She has an android and i have an iphone. All I do is turn off my phone so my phone doesn't update my location. How do i use my phone without it updating my location, but doesn't let her know?
