If anyone is tripping off to Vietnam in the next few days, I have a Viettel sim  (micro, can be punched  to  nano) you can have that is valid until 9 October with about 2.5GB left on it, as well as umpteen local minutes and txts, and 13 international minutes.

 

Pick up from Whitby available immediately, or from Wellington CBD from Monday, or I can snail-mail it.
