5 things you should do before leaving T-Mobile in 2026

Back in late June, T-Mobile announced plans to retire many of its oldest legacy plans. Customers on these older offerings would automatically be upgraded to a newer Experience plan, with the average price rising by about $4 per line.

Unsurprisingly, this move has caused a lot of backlash, and many customers are now frustrated enough to consider leaving. I understand the temptation, and for many, it could absolutely be the right move. Still, before you jump ship, let’s look at just five things you should do before pulling the trigger.

Check your latest bill for a price hike to see how much things have changed

Whatever you do, don’t panic and reactively quit T-Mobile without doing some homework. The very first thing you should do is check your latest bill, as it should have your new rate and plan by now. Review the plan you switched to and figure out exactly how much your entire bill will go up. The amount will vary, though the average family should expect an increase of around $20-$25 a month in total.

Now that you have a better understanding of the increase, it’s time to figure out your exact needs and whether any alternative carrier might be a better fit.

Determine your needs in order to narrow down your options

The truth is that not everyone will save money by leaving. Now that you know what your new bill is, I highly recommend creating a list of the features you care about. It’s especially important to figure out your absolute deal breakers.

Maybe you travel internationally regularly, enjoy streaming perks, or absolutely can only afford to buy a new phone if it is via an installment plan. You should also consider your usage habits. For example, you might have an unlimited plan but find that in reality, you use less than 10GB a month on average. In this case, you should at least consider plans with lower data limits, as you could save big without making a noticeable sacrifice over your current usage habits.

Once you know what features matter and what price you want to pay, the hunt can begin. Looking to make the switch a bit easier? We already have a great T-Mobile alternatives guide that could help make the decision easier.

One thing to understand now is that you are probably going to end up making a compromise here, no matter what you do. There’s a reason why T-Mobile is killing legacy plans: In 2026, it is impossible to get everything you want at such a low price point.

If you want to stick with any of the big three carriers, you’ll likely pay quite a bit more than you do with your current T-Mobile legacy plan. The good news is that you can still find most or even all of the critical T-Mobile features with prepaid; you just might have to put up with slightly worse customer service or a few other small missing perks. In fact, some prepaid carriers offer features you can’t even find with postpaid, like Google Fi’s state-of-the-art international coverage.

What if your most important “must-haves” end up costing more or the same at another carrier? Then you might want to just make the switch to T-Mobile Experience. For everyone else, keep reading.

Check your remaining EIP balances

Now that you know you want to leave for sure, it’s time to check in on any remaining device balances you might have. This is important even if your phone, watch, or tablet was ‘free’, as these devices are still locked to an installment plan; you just get (usually 24) monthly bill credits to cover the cost. If you leave early, you’ll have to pay for any remaining installment payments all at once.

Once you know how much you owe, it’s time to consider the math on whether now is the right time to leave. For example, if you still have six months of credits left on multiple devices, consider how much you’d have to pay to cover those credits, and if you’d still actually save by switching now.

If the new carrier is only going to save you $20 a month for six months but you owe $300 or more, you might just want to wait until your phones are paid off for good.

Don’t call your carrier yet; instead, generate a port-out PIN

At this point, you might be tempted to call your carrier and cancel directly. This might not be a bad step if you aren’t truly interested in canceling yet, as you could very easily be given a temporary bill-reduction credit to hold out a little longer.

But if you are 100% sure you want to cancel, don’t even consider calling until you’ve already requested a port-out. If you forget this step, you may just lose your phone number forever.

If you have port-out protection, you’ll need to go to your account settings via the website or T-Life to turn it off. After that, you’ll want to go to the T-Life app or the official website and log in. Then you’ll want to go to Profile Settings > Line Settings > Request a Transfer PIN. Once you have the PIN, it’s good for seven days.

Transfer all your lines, then pick a new plan

Once you’ve requested your Port-out PIN, you’ll want to go to the carrier site or app of your choice to sign up. In addition to the PIN you requested, you’ll also need your T-Mobile account number, which can be found at the top of your online account page.

That’s it. Your phone line should now start transferring over to the new carrier and plan of your choice. This process typically takes a day or so to fully resolve, though the exact timing can vary.

If you only owned a single line, that’s all that’s left. For those with more than one line, you’ll need to repeat this process for every line you wish to transfer. This includes free lines, tablet lines, and so forth.

Whatever lines aren’t transferred need to be canceled at this stage. You can’t fully cancel your account through T-Life this way, so you’ll either need to use live chat or call customer service. If you forget to cancel any remaining untransferred lines, you could end up with additional bills from T-Mobile until you do.
