Common sense is not as common as you think.
freitasm: Stay tuned. I have the press release here, but they asked to hold until 9:30am. The prices are better than those posted above.
loopylarry: I just logged into my Snap account - I was on the 145gb addon, now it is showing as a 250gb addon!
Pretty decent (except now I've got the 8 days until my account rolls over to use 175gb of data...!)
Better yet, if you purchase an additional data pack then data usage nights between 1am and 7am is unmetered, and doesn?t count towards the monthly allowance.
