Summary: If you want T-Mobile and WIFI but you don't want a smart phone or that price tag,this is about your option.It does everything nice,bluetooth,call quality. The only downer, internal space is non existent,but then again I didn't want a smart phone did I. It is a phone and it works, this is my 3rd in 3 1/2 years but I do put mine through serious workouts, dropping,weather, heat so I am not overly disappointed.
Summary: I bought this phone to replace the one I had before that was an identical model, the Katalyst SGH T739. I really needed this phone because it is the only T-Mobile phone that also connects to any local and open WIFI signal in order to make calls, instead of using a cell tower when a cell tower is not available. This replacement phone, however, has been a disappointment.
Summary: Okay, first let me start off with the positives of this cell phone. It does what I need it to do the most. It makes and receives phone calls reliably and the call quality is great. That having been said, I hate the Samsung Katalyst. I had a Nokia 6086 that had finally died and needed to replace it. I loved that Nokia. I had the 2 GIG microSD card. I was able to access the files on the SD card directly for use as ringtones.
Excerpt: Given how few UMA phones are offered by T-Mobile, I guess we shouldnt be TOO critical. But... I am just amazed that this phone currently has the following flaws: 1 - It is not possible to take a photo and save DIRECTLY to the SD card. You have to save to the phone (where only 5 or 6 photos fit) then MOVE them to the SD card. Oh, be sure to set up a bunch of subfolders on the SD card, because the picture file counter starts over at PHOTO_001.
Excerpt: I owned this phone and it had everything i wanted, or so i thought. First of all i bought this for the wi-fi. My home has little signal but a 10Mb cable connection.. my connection would fade in and out when running 2x wireless routes in a 1200 sq ft home. Had to disable alot of my security features to allow my phone to connect. wi fi runs off a slower and older technology. The phone had a buzzing when i first dialed the call.
Excerpt: It was a nice phone but sound quality wasn't any noticeably better or worse than the Nokia 6086 UMA phone. The Draw back of the phone and the reason why i returned it is because the carrier chose to disable certain functions of the blue-tooth. Namely not being able to tether it to my laptop or other phones to upload or back up the phone book and business cards.You'll have to spend extra money for the data cord for that. Why when blue-tooth is there? Shame on you Carrier.
