I'm getting some free add-ons to my Canadian iPhone account. The option was MMS or visual voicemail. I'm already getting name display/call display with early evenings calling (5pm) free so the two above is my dilemma. I already got unlimited SMS right now. Isn't MMS pretty much useless? Some phones can't handle the info + lag time. I can't see me using either add-ons much but what would be the case for MMS?
