Cannot send long(2 message) SMS.

[ygtgngr]

I don't know if it's my phone only but, when I write a text longer than 150 something characters it looks like it's send but people don't receive it. I thought maybe the phone was trying to send it as MMS so I checked the settings for that, but MMS works fine. Anyone knows how to fix this?

Is it only me having this problem? Can anyone with 950XL and/or on Fast Ring please confirm that it's not about the phone or the build?
