Hello everyone! I recently tried to resuscitate my old Nokia C7 phone and I encountered a big silly problem. Few years ago, I have set up a password for ESET Mobile Security BETA app and I can't seem to remember it. I really need to use the phone again, but with anoter SIM card. It's worth mentioning that I am unable to connect to the internet on this old phone - not even wi-fi! (this is why I gave up the phone) Is anyone kind enough to help a poor soul?
