Returning from the USA today... I have bought a 1GB prepay sim from AT&T for US$42. ph number is +1 512 423 4204
The account needs to be topped up by 7th May (US time).
Practically all the talk minutes and text messages are unused, practically all the data for this month is used up.
IIRC, it's about US$20 to renew.
Asking NZ$15
Any interest?
