I use the call forwarding service so that I can continue to receive my US calls when I am out of the country. I also use the VOIP functionality. For outgoing calls, I use vonage app or googlevoice  Majority of my calls are from family and we all use whatsapp for that. So, honestly speaking, my use for international sims has diminished significantly.

What do you use it for? 
 
Any 'strange' uses you use it for that others would be unaware of?
