My grandpa's iPhone 5S won't send SMS messages to non-iPhone phone?

He can call my mom's cell phone just fine, which is not an iPhone, but when it comes to texting, he can't send anything. I've made sure both numbers were correct and that all SMS settings were set right, but nothing changes. How is it possible that he can call her phone but can't send or receive messages?

Can I buy a sim free iphone 6 in us?

I'm traveling to the US in a few weeks and I'd like to buy the new iphone 6 I researched it but all the prices are 2year contracts for $199. I'm Irish so I can't have an American sim. Is there anyway I can buy the phone at a cheaper price without a sim (current sim free price is $699)

I'm a huge fan of the iPhone. However?

Many of us are getting so stressed out that the iPhone 6 doesn't have a microSD slot or removable battery.

My stress level is so high that I'm afraid it might lead to pnacreatic cancer

Is there something wrong with my eye?

So basically I accidentally hit my inner corner of my left eye, with the edge of my iPhone (yes I know, very stupid of me. Also it had a rubber cover on). It didn't hurt too bad, I mean I could definitely feel it. The next day I noticed that my inner corner and inner corner of my lower lid, felt sore when I blinked. I don't have a black eye, and no visible signs that indicate anything. I've checked to see if my eye appears red or swollen but it doesn't. Do you think there's anything wrong? And if you know what's wrong, and you have anything to make it better, please share your experience.

Am I deformed or is it a psychological issue?

When I look into the mirror, I look normal. My head is straight, everything is aligned aside from my right eye which's eyelid is a little droopy (if anyone knows why it is please let me know).

Once my image gets reversed though, say because of the iPhone's front camera, my head is tilted to one side, my ears are different, my jaw is out of shape, my mouth is out of shape, I just look physically deformed. I don't get called ugly, but I don't get called attractive. I'm actually seriously very concerned. I've never been one to be self conscious, I'm quite the confident person, but every now and then when I notice these issues, it just hits me like a brick and I break down.
