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: Mighty Mobile Fast Plan 365 Days gives you Unlimited (10Mbps) for $33.25 a month. That’s $201 a year less than this plan.
