You were able to call the Philippines? If that's the case it increases the value of the holiday gift add ons substantially as they always had a value between $0.01 and $0.05/min. The long distance calling add on for the Philippines is $15/100min or $0.15/min. At that rate the holiday gift long distance add on has a value of up to $75?!!
Public Mobile has always rounded up to the closest minute including ring time but your usage history will record the actual usage in minutes and seconds.
When you see all of the international destinations that can be called with regular add ons you can basically all all of them but the Philippines.....and a few more? You can always test for fun? If you get thru it will cost you a minute from your add on but if it fails like when I tried Kiev it costs nothing and when someone else managed to call his family in Iran (not Afghanistan?!!) and talk to them for 20 minutes I tested and reached the National Gallery it was a complete fluke and a free fluke at that. It didn't work the following day.....
No expiry it stays on your account until completely used.
I have used up exactly 5 min from my first "more is merrier" holiday add on gift from 2019 test calling......I've called the National Art Gallery of China, Ireland, Afghanistan (fluke and it didn't meter a minute either!), a British Morgage and Trust Co., McDonald's in Hong Kong and the Rock of Gibraltar. Only 1895 more international minutes to go until I run out!
