How do they know ?

[lukylok]

I gave in to my friend and bought a smart phone to communicate better when I am in Farangland.
It works very well and we have daily chats.
What surprises me is : some boys/friends I knew one, two, three years ago are finding my profile.
I am delighted - up to now - but as I have kept my profile to the strict minimum .....how do they find me ?

Profile on what App ?

Did you by chance recently install Line using an old SIM card? If so, every person who has saved your phone# in their contact list is going to be notified you're on Line.

Freaked me out when I first installed Line too.

You can switch off this option in Line setting, by the way

Yeah, but an IT expert such as Matt wouldn't know, would he?
