Yup looks similar to the one I had. I bought it at Car Toys because there weren't even T-Mobile stores yet. It took like 2 hours to transfer my number from another carrier (a new ability at the time!) and activate the account - what a process!
I remember the keypad was kinda small for my giant hands, but it would connect via this thing called "Bluetooth" to my Mac. Every time you got a text, it would show up on my Mac's screen, and I could reply just using my keyboard instead of typing out something using T9 on the phone itself. Soooo much faster. Somehow the ability to do that was disabled or something, I dunno.
I hadn't felt that sort of magical integration again until I realized you can copy and paste between a Mac and an iPhone you had on the same Apple ID (or however it works, I totally forget the details) so long as Bluetooth is enabled on both. Such magic and solved so many tiny little problems. I missed years of Airdropping as my last Macbook just couldn't work with Airdrop and I have no idea why not. Seeing Airdrop work instantly sold me on iPhones and I'll never go back to Android.
