T-Mobile Deals for Existing Customers in 2026

If you’ve been with T-Mobile for a while, you’ve probably noticed one thing. Most phone deals scream free phone, but they seem aimed at new customers. That leaves existing users wondering if loyalty even counts.

This post is for existing T-Mobile customers who want a new phone and want to avoid bill surprises later.

T-Mobile loyalty perks for existing customers

T-Mobile does offer loyalty perks, but they are not obvious.

Here are the ones that show up most often.

  • Loyalty trade-in credits

Some long-time customers qualify for trade-in credits up to $830. Phone model and condition decide the value.

  • Retention credits

If you call support and mention switching, some reps offer credits. A common one is $20 off today plus $20 per month for 6 months. That equals $140 total.

  • Targeted app-only offers

Many deals appear only inside the T-Life app under Promos or Upgrade. These usually never show on the website.

Two customers on the same plan can still see different offers.

Current phone deals for existing T-Mobile customers

Based on current listings and user screenshots, these deals show up most often.

  • iPhone 17 Pro and Pro Max

Up to $1,100 off with eligible trade-in. Usually tied to Go5G Next or another premium plan.

  • Google Pixel 10 Pro

Up to $800 off. Some accounts see offers without a trade-in.

  • Samsung Galaxy Z Flip 6 and Z Fold 6

$1,000 or more off with trade-in or add-a-line offers.

  • Samsung Galaxy S25 FE

Up to $800 off with a new line and trade-in.

  • Revvl 8

Often free with add-a-line promos.

  • Pixel 9 Pro and iPhone 16 family

Still available with solid trade-in credits on select plans.

How these deals actually work

Most discounts are monthly bill credits spread over 24 months.

You do not get the full discount upfront.

Cancel early or switch carriers and the remaining credits disappear.

Plan choice matters. Bigger discounts usually require premium plans that cost more per month.

Trade-in value drops fast if your phone has cracks, battery issues, or age.

Example
A $1,000 deal over 24 months equals about $41.67 per month. Leave after 12 months and you lose around $500 in credits.

Should you upgrade now

Upgrade if you plan to stay with T-Mobile for at least two years.

Upgrade if your phone qualifies for high trade-in value.

Wait if you do not want a plan change or a 24-month lock-in.

Be careful with add-a-line deals. The phone discount may look big, but the extra line can cost $25 to $35 per month.
