Why does my iphone 5c keep saying invalid sim?

I ordered an iphone 5c off line around October and it was used but when i received it i went to the store and bought a Straight talk sim card so i could use it through that company and it worked great but lately my phone will randomly say invalid sim and sometimes restarting my phone helps but recently it hasn't been helping at all…

IPhone 6s Plus ear speaker and front camera not working?

I bought a light mod for my phone that made the apple logo light up. I thought I installed everything correctly until I got a phone call and couldn t hear anything, and I realized the top portion of the phone isn't working. I checked if it had to do something with the cables of the screen but I couldn t find what was causing it.

How could I do pressure switch?

So I was at table dinning with my little brother when he said that people couldn t stay up in air for more than one second and I told him that we could but he wasn't believing me.

So IIm thinking about making pressure switch that activates a chronometer when we jump and it does a lap when we land on it again. It should record the time spent in air.

Now I know that I can make a switch with aluminum foils and when we take off the circuit opens and it closes another circuit which would activate the chronometer. Now the problem is when it's landing.

IIm gonna se if we can activate the iPhone chronometer with the headphones which would be helpful because I wouldn t need to buy one, I could just use some old headphones and plug it to the iPhone.

Any help would help me a lot!

Iphone 5s apple Id account isn't deleted. Is there anything I can do?

So I've only had an android and I had no idea about the iPhone when I bought it. I bought an iPhone 5s off of some guy on Craigslist and he said the phone was factory reset. He didn't seem sketchy at all. But I took it in to at&t and the apple Id wasn't deleted and they said there was no way to access the phone until the account was deleted! There has to be something I can do right? I mean what do I do? Just throw the phone away? Lol jk but seriously the guys not writing or calling back which makes me think it's a stolen phone. There has to be some way to reset it so I can use it! Or else I'm just going to go buy a new phone and this iphone is going to sit in my desk for years. What do I do?

Accidentally erased all contents and settings on iOS 8.6 jail broken iPhone 5s?

As stated above I think I might have bricked my iPhone. I had gotten my new phone and my dad needed the old one to sell so when I gave it to him with me being all excited and ignorant pressed on that without thinking twice. I told him that I would fix it but it's not going so well. I tried putting it into recovery and connected to iTunes and tried DFU mode first (probably not a good idea) and it downloaded iOS 9.2.1 I assume cause it was 1.82 GB. Either way I got a error code 3014. I then tried recovery twice got same code then tried DFU a couple more times and nothing. A blue screen came up for a second and disappeared in the process of all this don't remembered exactly how I cause it to happen. Basically my phone is stuck/frozen and I when I try to restore it In recovery and DFU I get an error 3014 after It completes "extracting software". I don't know what to do. Help would be greatly appreciated thank you for your time.

What to do with an iphone 6s plus i got in my mail?

I got an iphone 6s plus in my mail today and i never ordered for an iphone, never entered any competition to win one and i also never filed for a lost device through an insurance company, I DON't EVEN HAVE INSURANCE ON ANYTHING. I just opened my mail and found an iphone 6s plus in there… Brand new… And it seems to be sprint locked. On the stamp… The mailing address is correct but only my first name is on there, my last name isn't on there, do i give it to the police or call fedex or what?
