Using the roam beyond package in New Zealand
I’m going to New Zealand for 18 days. I was thinking about purchasing the roam beyond package. Can I just start it once I arrive in Nee Zealand at the airport and then will it be ok to buy another package (as they only last 10 days) again once the first package has finished, again in New Zealand while I am out there. I take it if I set my bill limit to 0 I can’t be charged any accidental charges? Is there anyway of making local phone calls that won’t cost an arm and a leg. I know I can use WhatsApp etc but I mean normal phone calls.
