@Bluiztantj Firstly, if you do not add any credit to your account, then you cannot be charged for any service because Smarty do not operate any credit accounts as such.
MMS are limited to 300kilobytes generally and so you may struggle to send a reasonably sized picture that way. Probably better to send via something like WhatsApp or attached to an email - these use data and do not have the small size limit.
