The carrier T-Mobile has just announced a five-year price guarantee on all of its 5G mobile plans this week - a useful promotion available to both new and existing customers renewing a plan.

Even though the carrier's unlimited cellular plans usually run over a two-year period, this could be a useful option if you're looking to insulate your budget from inflation or any other unwelcome surprises. Note, however, that it doesn't extend to any additional taxes or fees, which are always worth considering before you sign up.

It's also worth noting that T-Mobile isn't the first carrier to announce a price guarantee. Just last week Verizon announced a three-year guarantee so there are plenty of options right now. As of writing, there's been nothing from AT&T but I wouldn't be surprised if this carrier announced something similar soon either.

Are you looking to bundle your plan with a shiny new phone? I've attached a number of the best T-Mobile deals on the latest devices below.

Note, however, that it doesn't include any tax increases or fees.

T-Mobile's headline deal on the latest iPhone 16 series is a massive trade-in rebate of up to $1,000 - a rebate that's technically enough to cover the entire cost of the iPhone 16 Pro. To be eligible for the biggest discount here, you'll need a line on the Go5G Next plan, which is unfortunately the priciest plan of them all at T-Mobile. You can, however, get a rebate of up to $830 off on one of the cheaper plans, which is enough to cover the cost of the standard iPhone 16.

This particular deal is great if you can't simply trade in an old device for a discount.
