Did that help at all @eloram93?
By any chance are they using a Samsung Galaxy phone?
This issue seems to be common with those.
As I said unless the default messaging app has an option to prevent "long" text messages from being converted to MMS then the only solutions are (a) only send "short" text messages or (b) install a different messaging app. In the past I have used free versions of apps such as Textra, Handcent, GoSMS, Chomp etc. some or all of which allow you to prevent text messages being converted to MMS but it's a long time since I used them and you would need to research what are the best free or paid messaging apps with this feature these days.
Hope this helps.
