Phone Trade-In Value by Carrier: AT&T vs Verizon vs T-Mobile vs Selling Online
You have a phone to sell, and every major carrier seems to be advertising a large trade-in discount. Those offers can be valuable, but the headline amount often combines your phone’s basic trade-in value with promotional credits tied to a new device, qualifying plan, or installment agreement.
The phone trade-in value by carrier depends on the exact promotion. Some deals require a certain plan or eligible phone. Others are open to both new and existing customers. Promotional credits are usually spread across 24 or 36 months. If you stop meeting the offer requirements before the promotional period ends, you may lose the remaining credits.
This article compares promotional carrier deals, standard carrier trade-ins, and selling your phone online for cash. It also includes live SmartphonesPLUS offers so you can build a clearer phone trade-in value by carrier comparison before choosing an option.
The trade-in values in this article are pulled from the SmartphonesPLUS live pricing feed and reflect offers available at the time of writing. Prices update regularly, so your actual offer may differ.
How Phone Trade-In Value by Carrier Works
Carriers can offer two different types of trade-in value.
A standard trade-in is based mainly on the phone’s model and condition. Depending on the carrier, it may be provided as an instant credit, account credit, gift card, or one-time bill credit.
A promotional trade-in is connected to the purchase or financing of a new phone. The promotional portion is usually spread across monthly bill credits. AT&T and Verizon commonly use 36-month promotional periods. T-Mobile commonly uses 24 months.
Selling to an online buyer works differently. You receive a cash payment after the phone is received and inspected. You can then use that money with any carrier or device seller.
In one September 2025 comparison, Consumer Reports found that an iPhone 16 could receive up to $450 from Apple. The carriers it reviewed were around $350 in bill credits.
The gap between those two numbers is a useful reminder that the payout type matters as much as the headline figure.
Carrier vs Online: Side-by-Side Comparison
| Factor | AT&T | Verizon | T-Mobile | Selling Online |
|---|---|---|---|---|
| Promotional payout | Monthly bill credits | Monthly bill credits | One-time and monthly bill credits | N/A |
| Common promotional period | 36 months | 36 months | 24 months | N/A |
| New line required | Depends on the promotion | Depends on the promotion | Depends on the promotion | No |
| Qualifying plan required | Often | Often | Often | No |
| Must maintain eligibility | Yes, for the full promotion | Yes, for the full promotion | Yes, for the full promotion | No |
| Standard trade-in option | May be available | Account credit or e-gift card may be available | One-time bill credit may be available | Cash |
| Payment timing | Depends on the offer | Depends on the offer | Depends on the offer | After inspection |
| Can use the value elsewhere | No | No | No | Yes |
AT&T Trade-In Value
Promotional AT&T trade-in value is usually provided through monthly bill credits over 36 months. Current offers may require an eligible trade-in, a qualifying unlimited plan, and a 36-month installment agreement. A new line isn’t required for every promotion, so check the specific offer rather than assuming.
AT&T may also provide a standard market-value trade-in amount that differs from the advertised promotional credit. Compare the full promotion, plan requirements, and standard offer before deciding.
Verizon Trade-In
A promotional Verizon trade-in offer may be spread across 36 monthly credits. Some promotions require your line to remain on an eligible myPlan option for the entire credit period.
A standard Verizon trade-in can work differently. Depending on the transaction, Verizon may provide an instant credit, one-time account credit, or Verizon e-gift card instead of recurring promotional credits.
The remaining Verizon trade-in promotion may end if you switch to an ineligible plan, end the device payment agreement, or stop meeting the offer requirements. Read the specific promotion terms before sending in the phone.
T-Mobile Trade-In vs Selling
The T-Mobile trade-in vs selling comparison involves more than the 24-month promotional period. T-Mobile may apply the phone’s standard trade-in amount as a one-time bill credit and provide the remaining promotional value through monthly credits.
If you cancel the account or stop meeting the promotion requirements, the remaining monthly credits may end. Selling online may be a better fit when you want cash. The T-Mobile promotion may be stronger if you already plan to keep the qualifying service.
What Your Phone Is Actually Worth Right Now
The table below shows current SmartphonesPLUS cash offers for six popular devices. These are real cash amounts, not bill credits, and they do not require a new line, a specific plan, or a 36-month commitment.
| Device | SmartphonesPLUS Cash Offer (Good, Unlocked) |
|---|---|
| iPhone 16 Pro Max (256GB) | $524 |
| iPhone 16 (128GB) | $380 |

| iPhone 15 (128GB) | $261 |
| Samsung Galaxy S25 Ultra (256GB) | $500 |
| Samsung Galaxy S25 (128GB) | $274 |
These are direct cash offers. No new line. No plan requirement. No 36-month wait. The amount you see is what you receive after the phone is inspected and confirmed to match the condition you selected.
How Promotional Bill Credits Affect the Value
Promotional bill credits aren’t the same as cash. They’re also different from the standard trade-in value a carrier may provide as an account credit or gift card.
If a carrier offers $360 in promotional credits over 36 months, you receive $10 off your bill each month. You receive the full $360 only if you continue meeting the promotion requirements for all three years.
An online cash offer is paid after the phone is inspected. Once you receive it, you can use the money for any phone, plan, or other expense.
The phone trade-in value by carrier can look higher because promotional offers are designed to keep you on an eligible plan. Compare the total credits, plan cost, commitment period, and current cash offer before deciding which amount is more useful.
The same timing pressure shows up when you look at how phone trade-in values drop over time in general.
When a Carrier Promotion Might Make Sense
A carrier promotion may be worth considering when you already plan to buy a new phone, keep the required plan, and stay with the carrier for the full credit period.
Look at the total cost of the plan rather than the trade-in number alone. A larger promotional credit may not save money if it requires a more expensive plan you wouldn’t otherwise choose.
Carrier trade-ins can also be convenient. Depending on the offer, you may be able to complete the process in a store or send the phone by mail. For some people, that simplicity is worth more than the difference in cash value, especially if the phone is going toward a device they were already planning to buy.
The offer is most competitive when the promotion matches plans you already had. Selling online may make more sense when you want cash, don’t need a new phone, or don’t want to maintain a qualifying plan for two or three years.
The carrier trade-in vs phone buyback comparison gets into more of these numbers if you want a deeper breakdown.
Compare the Full Value Before Deciding
The value you get from a carrier isn’t always a single number. A carrier may combine the phone’s standard value with promotional credits tied to a new device, installment agreement, and eligible plan.
The live SmartphonesPLUS table gives you a current cash offer for comparison. That makes it easier to see how much money you could receive without changing plans or waiting for monthly credits.
Compare the phone trade-in value by carrier with the cash offer, required plan cost, and length of the promotion. You can then choose the option that fits your budget and how long you expect to stay with the carrier. A few minutes of comparison now can make a real difference in what you actually walk away with.
