Im sure the new phones are also wifi capable.
EXTRA INFORMATION: T-Mobile have it written somewhere in their rules/guidelines that if you use more than 50GB of data on your phone within a 3 month period and majority of your data use is using your phone as a wifi hotspot... that goes against their policy and may deactivate that line.
My previous "EXTRA INFORMATION" was written incorrectly ((((sorry about that))))) here is the correct wording from T-Mobile's website the most recent Terms & Conditions.
Unless explicitly permitted by your Rate Plan or Data Plan, you are not permitted to use your Device or the Service in a way that we determine:
Results in unusually high usage (specifically, more 50GB (updated periodically) in a month) and the majority of your data usage being Smartphone Mobile HotSpot (tethering) usage for any 3 billing cycles within any 6 month period;
barcodeable posted some great info here. Have you decided which phone you wanted? You can always take a look at our Smartphones & Cell Phones | Compare our Best Cell Phones & Smartphones page and if you find something that catches your eye, we can take a peek at the features to make sure it has what you need.
The best phones T-Mobile has out right now are The IPhone's, the Galaxy S9 and S9+, the note 8 and the LG V30. Avoid the LG G6
