We will be travelling round NZ in a campervan for 7 weeks next year. Obviously the data download cost of using our UK iPhones with 3G will be prohibitive even if we can get free wifi in some places, so we are wondering whether we can get a suitable SIM card in NZ and a contract which will give us a data allowance when we are on the move. I haven't ever used a dongle but maybe this would be the answer.
I know we are on holiday, but we have reasons we need to stay in touch :-)
Any advice please?
