I used a sim card since more than half a year, I just used it for internet, never gave the number to anybody.

I never got any SMS spam on this number.

Yesterday I used this number to register a new Line account. Today in the morning I had a spam SMS advertising some gambling website.

Looks suspicious to me, did anybody else notice this?

Look in your LINE Home page: settings: privacy: scroll to "Filter Messages": check it. Scroll further to "External App Access" tick either "Only for people on your friend list" or "Never allow"

Not guaranteed to work blocking all unauthorized access.  LINE seems to allow chosen apps access despite settings.

I'm talking about a standard SMS, sent to my phone number after I used it to register for Line, not a message within Line.

Seems like a few holes but...

First off, do NOT click on that SMS. Delete it ASAP.

 

Second, Turn Off Auto-add friends, and Allow others to find me.  Main, Settings (gear) General settings, Friends.

 

Once you use LINE one time, someone other than LINE has your number.

 

This came in as an SMS, correct? Not as a LINE msg?

 

Did you use the LINE app at all between registering and receiving this message?

 

 

 

 

 

 

 

 

 

Newer versions of Android, and the manufacturer's UI have SMS spam filters, and number blocking, which are quite useful and effective.

 

My Messages app is version 8.0.059 and has a Spam & Blacked feature.
