Using Fongo in Nicaragua

Hi. I just signed up for Fongo and have forwarded my Public Mobile number to it whilst here in Canada to test it out. Phone calls come through right now. I have tried to texting but it comes through on my PM phone likely because I still have the wifi going. Just wondering though if it will work for phone AND texts once I am in Nicaragua since my public mobile sim will not work down there? Does anyone know - or will it only call forward voice calls?
Thanks
