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 Starter Plan gives you 5GB/mo for $25.00 a month. That’s $240 a year less than this plan.
