TL;DR: Pre-order the new Samsung Galaxy Z Fold 8 for free when you trade in an eligible device on Experience Beyond with T-Mobile.

If you’ve been waiting for a sign to finally jump to a foldable phone, your window to do it for free is rapidly closing.

Samsung’s brand-new Galaxy Z Fold 8 officially hits shelves on Aug 7 — which means this is your absolute last chance to lock in T-Mobile’s wild pre-launch preorder promotion.

Right now, T-Mobile is running the best launch promotion we’ve seen for Samsung's latest flagship: up to $1,900 in bill credits spread over 24 months. If you have an eligible trade-in, that effectively wipes out the entire $1,899.99 price tag. Yes, T-Mobile is giving away the Galaxy Z Fold 8 for free.

At nearly $2,000, buying the Z Fold 8 outright is a hard sell. That makes taking advantage of this pre-launch window the smart play.

We really like the Samsung Galaxy Z Fold 8. This "redesigned foldable shines as a media powerhouse with a wider, more comfortable display." If you use your mobile device as a handheld workstation, gaming rig, or multi-tasking hub, getting flagship-tier Samsung hardware for free is an absolute steal — provided you're already on (or willing to switch to) T-Mobile's top-tier unlimited network.

Thinking about making the leap to Samsung's latest foldables? You're not alone. These new smartphones "are breaking the company's pre-order records for foldables."
