License? in Emsisoft Mobile Security Posted November 19, 2015 · Report reply Hello Thomas, I did receive the serial number and followed what you said in prior posts back then and it worked but then reverted back for some reason. I looked through my folder for Emsisoft and I don't see it. It was through google play store I purchased for $9.99 so I guess I threw it away. It's under Brittany Frank around Sept 16th, 2015. A mastercard was used.
