Vba to send sms to mobile number

Hi everyone.

I need help with little tricky problem.

I need a macro code to send sms to few numbers everytime as and when i press the "PAID" button in sheet "INVOICE"

SMS message can be "Hi you have made a sale to 'customer name' of 'amount'"

Customer name refers to cell "C3" and amount refers to cell "Q42"

I have attached my workbook.

Is there any solution to it?
