Unlimited plans at 10Mbps or faster count as more data than any allowance. Plans you pay a year upfront are only compared with each other, and no plan is compared with one that needs another service. Commissions never affect scores. How the SmartScore works
💡 Save money: Skinny $13 Plan (1GB Rollover Data) gives you 1GB/28 days for $14.12 a month. That’s $47 a year less than this plan.
