I use phone alt 2 as mobile number, I would like to notify clients about thier bill due time via SMS ( text messages ) or if we go a major problem in the internet customer will not be able to check his e-mail so if you can arrange this future in coming optigold versions
The phone email address for most of the customers need to be setup ... SMS doesnt need to. its an idea just hoping to work sometimes
In what country do your customers reside?, US or UK?, I could certainly help with an SMS invoicing system in the UK, but you'll need to contact me privately.
My internet provider use that system SMS Notification, I found it useful when your not home/office and something occur within your subscribe services with the said system you can be notified the soonest possible time.
