No longer free?

Ive had this app installed on my iPhone for years and used it, with no issues, to call my folks when they are in the States on holiday.

Recently, when Ive tried to use it, it tells me that my free trial is over (didnt know that free trials last years and wasnt aware that there was a trial period) and that Id have to pay for the app.

Just another app that is going to get deleted in favour of one that is better and FREE!!
