I know of a Mobile service provider which let's users to recieve SMS/MMS via E-mail.
It goes like this, when the phone number (local) is 999999999 the e-mail will be
99999999@sms.mobitel.lk
9999999@mms.mobitel.lk
Now for the Q.s
#Can I add a attachment feature for this.
#Can I only ask the users for the phone number and Add "@xxx.mobitel.lk" at the end automatically
#Can I let users to choose whether SMS/MMS via a combo menu
This can lead to a free SMS service dudes, I made one for SMS myself, but still cannot do the combobox, and attachment. Have No Idea of how to use it, Really complicated.
