Love having multiple phone numbers!

I’m actually using one to sell Jeep parts on Craigslist all the time and another one for my social Jeep groups. This way I keep my real cell number for just close friends and family. Love how I can keep the number profiles and contacts separated and can clearly see what’s what in the main view.

Perfect for online business

I love not giving out my real number when selling online. Masc gives me the comfort of having a second and third number on my phone. Latest version much improved and their support staff is very responsive.

Perfect for my business use

I’m using MASC as a second number on my phone as my business line. It is great for keeping my personal and business communications separately on the same phone.
