Customer Reviews
Love my new Samsung, great deal!
I finally upgraded to the new Samsung Galaxy! T-Mobile had an amazing trade-in deal that paid off my old phone, which was a huge help. I got the Magenta MAX plan and the Netflix on Us perk is fantastic. The ordering process was simple, and my new phone arrived quicker than I thought, took about 4 days to reach me in California. Setting it up was a breeze, and the 5G speed is incredible where I live. Definitely a happy customer, I'm recommending them to my sister who's looking to switch from Verizon!
Decent service, minor hiccup
I moved my family lines to T-Mobile for the Go5G plan during a 'free line on us' promotion. The online process was mostly smooth, but activating the eSIM on my Apple iPhone took a call to customer service. They resolved it quickly, within about 15 minutes. The 5G Home Internet setup was super easy, just plug and play. Speeds are good for our needs, though sometimes during peak hours it can be a tad slower than expected. Overall, it's good value for the price, especially with the discounts I got.
Good switch, fast shipping
I switched to T-Mobile for the Go5G Plus plan and a new Google Pixel phone. The signup was easy online. My phone arrived in 3 days. Service works great so far.

Thinking of switching to T-Mobile. Do they really pay off your old phone if you port your number?
Anyone know how the T-Mobile Home Internet is for gaming? Worried about lag.
