The $1 and $3 for the first 3 months deals still seem to be going on at Lycamobile. From infinitely many experiences both on OzBargain and Product Review, it is the worst possible choice for porting your main number. However, it could be ok as a secondary data sim for a disposable new number.
If you do use or have used a Lycamobile sim recently, what sort of speeds did you get using mobile data on 4G, if you managed to get the sim working?
Thanks to those who vote.
