Text message from Skinny advising calls and texts to Tonga are now free up until 1159pm 23rd Jan.
Hopefully this might help a few families to be able to reconnect.
I can't find anything on their website about this, but have attempted to upload the text I received, so anyone getting a skinny simcard can ensure they get the same deal.
In light of recent events in Tonga, to help support communication amongst family and friends, calls and texts to Tonga are now free of charge until 11.59pm Sunday 23rd January. Any calling/texting activity to Tonga that's already occurred between 5pm Saturday 15th January to today (and which has used your credit), has now been refunded. /Skinny
