Carrier Trade-In vs Selling for Cash: Who Pays More?

Updated June 2026 · 7 min read

Every carrier advertises a big trade-in number. But 'value' delivered as 36 months of bill credits is very different from cash in hand. Here's the honest comparison.

Credits vs cash

Carriers (T-Mobile, AT&T, Verizon) pay trade-in 'value' as bill credits over 24–36 months, contingent on buying a new phone and keeping a qualifying plan. AT&T's is store credit only. A buyback service pays cash within a day with no purchase required.

The strings

The headline only materializes if you complete the full term. Pay your device off early, switch plans, or leave the carrier, and you lose the unpaid credits. There's nothing to lose with an upfront cash sale.

When a carrier trade-in does make sense

If you were going to buy a new phone from that carrier anyway and will stay put for the full term, the credit can be competitive. Otherwise, sell for cash. Compare your exact carrier: Verizon, AT&T, T-Mobile.
