Maybe move to Spark - their roaming works fine in Australia. Skinny would have the same reception as Spark in Wellington. Otherwise 2 Degrees or One NZ roam well to Australia in my experience.

 

 

I know the title is about Skinny how ever I am on Spark.

 

I have been told that Spark and Telstra 4G networks are not compatible.

 

Not correct the issue is VoLTE is not compatible
