Im still on the $16 Big value combo
Why am I left out of the extra data goodness? because you are on a grandfathered plan
How do I change to the Core combo ? on their website
Will I loose all rollover minutes if I change combos ? no
Is big Value no longer offered, I couldnt see it on the website
There are some other differences - for example the combo lasts 28 days instead of 30 (or was it a calendar month) and there were some minor differences in the "not included" minutes/texts.
