Financing vs. Buying Outright
Carrier installment plans are convenient and often 0% APR, but they lock you into a carrier โ and you may be charged an early upgrade fee if you leave. Buying unlocked gives you freedom to switch carriers and take advantage of competitive SIM-only plans, which can be $20โ$40/month cheaper than postpaid carrier plans.
The real math requires comparing total 2-year cost: (phone + plan) for financed carrier vs. (unlocked phone + cheaper MVNO plan). Often, buying outright on a budget carrier saves $500+ over two years even if the phone costs the same.
About the Break-Even Point
The break-even month represents when cumulative savings from a cheaper unlocked plan offset the upfront cost difference. If you switch to a $25/month MVNO instead of a $70/month carrier plan, you save $45/month โ meaning a $999 phone pays for itself in about 22 months compared to financing plus a carrier plan.
