Wife and I are off to Ireland for 4 weeks plus one day in six months. Have read notes about roaming on our Prepay Flex plans. Went to OneNZ store in mall today to clarify some stuff. Store was loaded up with queues!! So here's some queries you folk should be able to answer in a jiffy, and jump the queues!!

I know to turn off mobile data before i leave NZ. I know to Text 777 when I land at Dublin. I know that, on our plan, we can buy roaming packages (Add on) for one day or for a week - by Text to 756. And that the Add ons can only be purchased when overseas. I know that I have to pay per package as we purchase. So, I should ensure both our prepay accounts have enough credit to cover Roaming Add ons. We both have the OneNZ App on our phones.

Have I got that right so far.

More queries ...... As we are in Ireland for 4 weeks plus one day can we purchase four (monthly) Add ons plus one (One Day) Add on packages in one transaction. Or would we have to buy only one Add on package per day or as needed over the period we are in Ireland.

We transit via San Francisco on way to Ireland. If I (just me) want to use my mobile while in transit can I follow procedure as above to connect into roaming "mode" and then buy, say, just one Day Add on pack? And, if I do not use up all of the data, txts etc of that package will the balances carry over to my roaming account that I sign up to once in Ireland?

Would welcome any answers and/or other tips to our understandings as above.
