What to look for with T-Mobile deals
Get ready to shop around
As with most ISPs and carriers, T-Mobile saves its best deals for new customers. However, this doesn’t mean that existing customers are left out of the fun. If you upgrade T-Mobile service or bundle phone or internet service, you may qualify for some promotions. Additionally, T-Mobile offers great bonus perks to customers through its T-Mobile Tuesdays deals program.
Trade-in versus buying a phone
T-Mobile’s not the only carrier to offer huge trade-in bonuses for the latest Apple iPhone or Samsung Galaxy phones, but make sure these credits are a fit for your phone-buying needs. In many cases, the best trade-in deals require you to upgrade phone plans or add a new line to your phone plan. In other scenarios, your trade-in credit will be dispensed as 24 monthly bill credits that’ll be applied over two years.
Upgrade for the best deals (if it makes sense for your budget)
T-Mobile’s All-In 5G Home Internet and Experience Beyond phone plans come with some of T-Mobile’s best deals and savings, but make sure the plans fit your lifestyle and needs.
If you have a larger home, consider upgrading to All-In because the plan includes a mesh Wi-Fi extender for better home internet coverage. Similarly, Experience Beyond’s unlimited Wi-Fi hotspot, discounted smartwatch plan, and international coverage features make it an excellent fit for frequent travelers.
What real customers told us about T-Mobile
So far, we are very satisfied with T-Mobile. We switched from Xfinity. The cost is much cheaper, and our service has had much less interruption than we had with Xfinity. Customer service with T-Mobile is much more pleasant, too.
They provide a very reliable network at a pretty competitive price. They're certainly cheaper than my previous service provider, and I've noticed fewer service outages with them as well.
It's super easy to pay your bill and look at future payments. It comes with benefits like free Netflix and free Apple TV. I also like the internet box because it shows you how good your connection is.
