Moving abroad outside the EU- would like to keep my sim

GeorgeP_1626885 If a sim is not used for 180 days, it is deactivated and the number is lost.

If you ensure that you buy at least the minimum plan every six months, then you should be able to keep the sim active and retain the number.

Once you buy a plan, you won't be able to make any calls as you will be in NZ.

For 2FA, you will need a plan as far as I can see, so I'm not sure that you can always have it ready unless you buy a plan EVERY month - the minimum will do. Another point to consider is that 2FA does not always work in another country - we have herd this from members before.

In summary, I think you may be best just buying the Smarty plan every 6 months to retain the number (as I said above), but would be better off getting a local sim for use in NZ so that you can definitely receive 2FA text messages (assuming the accounts needing 2FA are in NZ anyway?)

Not sure if anyone else will have a better solution.
