Texting pictures iPhone

Do you have MMS turned on in Settings>Messages? Have you contacted your carrier to make sure that your account is properly configured for MMS? Do you have cellular data turned on?

After checking the settings, I realized my cell data was turned off.. Since I'm on wi-fi most of the time, I never had the cell data turned on (until now )

And I did a test and it worked fine... My question is if I send pictures to a non iPhone, with wi-fi on and cell data on, do I get charged since my cellular data is on but I'm also using wi-fi when sending pictures ??

If you are sending pictures to a non-iPhone, the picture is sent over cellular data and will count toward your cellular data allowance.
