Here are a few purchase scenarios you might consider.

3 $25 buckets, 9 $5 buckets: $120 + $30 airtime: 1.6 GB costing $150
6 $25 buckets, 6 $5 buckets: $180 + $20 airtime: 3 GB costing $200
9 $25 buckets, 3 $5 buckets: $240 + $10 airtime: 4.5 GB costing $250
12 $25 buckets: $300 + $25 airtime: 6 GB costing $325

For comparison, the expected per-year cost for really basic iPhone service at $55 per month: $660 (Auntie thinks that's the lowest available, you might want to check).
