Virgin Mobile added 1GB to select plans a few months back but this didn't include the $20 BYO plan. Now it does!
$20 per month nets you $200 of calls (roll over included) and 1.2GB data (4G) counted per kb.
BYO plans have no contract, and the usual Virgin to Virgin freeness applies.
This same deal was on late 2013, but for those who missed out, here it is again. Good choice for a low cost plan on a fairly well known carrier.
Expires 6th April 2014.
