Can you try if it works when sharing with WhatsApp?
I don't seem to be able to install WhatsApp. Maybe because my tablet has no phone number? I'm not sure.
Edit: that's exactly the reason. An app which aims to give you free calls and text messages requires that you pay for a call and text messaging service? Seems kinda silly:

NO ADDITIONAL FEES: WhatsApp uses your phones Internet connection (4G/3G/2G/EDGE or Wi-Fi, as available) to message and call friends and family, so you dont have to pay for every message or call.
They mean you can call by voip and the messages are sent over the phones internet.
They were completely free until they became so widely used that they decided to charge, i believe 0.12$ per year, after the first year. I wasnt charged anything yet, i dont know why. But since practically everyone has it installed it would make sense. Its pretty useful not having to use sms.
Maybe someone has whatsapp installed and can test it?
