Is your code for...
F-Secure Safe or F-Secure Internet Security?
Unfortunately these are two different products! So make sure you got the right one.
Card reads F-SECURE SAFE Internet Security for all devices and is for 3 devices for 1year
Then call or chat with F-Secure customer support for further help!
May I know on which device/OS are you trying to enter the code for the IS? Have you tried to copy paste the code if you are typing it otherwise? Did it work?
If you are referring to just F-Secure Internet Security, you can then find that it supports Windows OS only as mentioned under Technical Details in the link here. I assume, your Acer smartphone should be coming with an Android OS.
If you are using F-Secure SAFE (as mentioned in one of your replies), I would recommend to contact our support so that they can look at your issue and troubleshoot further.
