Yeah, the rollovers are great! I have something like 3,000 min over the last year. They start to expire on a monthly basis, that way you don't lose all your rollover minutes at one time, which is nice.
Another nice feature is the 7pm-7am night and weekend minutes. It's an extra $8.99 a month, but it allows you to use your 5,000 night and weekend minutes earlier on say Friday at 7pm til Monday morning 7am đ
