I’m planning a trip to New Zealand and thinking about using PrimaSIM instead of Airalo. Not going to buy SIM after arrival; don't like the troubles of getting it. I’ll be taking walks around popular spots and places where people usually hang out, so the connection quality is very important to me. If you used it in New Zealand, how was its performance to you?
If you are just travelling to NZ and back, get a New Zealand telco eSIM so you know it will be reliable and you can get support if needed. Also being able to make local calls if you go with a talk option.
There are 2 main sellers with budget resellers. The main ones are Spark and One NZ
