Problem on Meizu M8

Hi everybody, i have some question about my new Meizu m8.

1) seems some people don't get SMS message i send to them and seems sometimes i don't get them.
Does someone got a way to get SMS message reception option?
Does someone has the same problem?

2) My meizu doesn't read all the pictures i put in, does meizu has a limit of quality pictures, like canot read the 8million pixel one?

Thank you for answering me

1) are you sending it to a number with a country code (i.e. in the UK I would have to send to +447... rather than 07...)?

2) yes I think it does have a maximum resolution but I don't know what it is.

Max resolution for images is about 2048x1536 or something...

1) I have experienced that a little while back ago. I couldn't recieve any texts. But just the other day I looked into 'SIM Manager'. And pressed the option second from bottom of the page and pressed 'Done'. For me it loaded about 15 messages, wich were the ones I didn't recieve the other day. Dunno why, though.

Thank you to all of you for answering, i'm often mooving between china and france, so it was maybe a number problem in my contact list. I added + to them, hope now it will work, seems it's ok.
