People using WeFiApp said that putting a note under their neighbour’s door was beneficial for them both, you can try using the below note

Let us know how it went.

 

 

Dear neighbour
Have you heard about the new app called WeFiApp ?
It allows us neighbours to share the wifi internet connection as well as the costs.
Check out their website WeFiapp.com or download the app WefiApp on either Apple store or Google Play.


Thanks 
Your neighbour
