I had a Samsung S5 for a couple of years and loved it. I recently upgraded to the S7, but my hubby opted to stick with his S5 for awhile longer. We use T-Mobile and the S5 works well with them. I’m considering grabbing a couple of these to replace the kids’ crappy android phones. Love, love, love the waterproof feature of this phone.
You will be fine with ATT on the phone. With this being the T-mob version it means the tethering feature isnt locked down, so bonus (edit: tethering isnt locked on some plans for ATT)! If it were an ATT phone to use on the T-mob network you would miss out on the wifi calling feature of T-mob. ATT hasnt yet supported wifi calling features (edit: on all handsets), unless you go to google voice or something similar, which is a whole different kettle of fish. I have been running a Note 4 for a while and really like it. T-mob finally released the 6.0.1 update and it works very well. You can always skip this deal and just get a Note 7 this month for 4 times the cost. That bad boy is starting at 850 a phone. Yowza!
edit: apparently ATT has changed a few things, I stand corrected a bit.
Quick answer either. However you want to know when carriers have marked the S5 as EOL (I know AT&T has) That doesn’t mean you won’t get updates, but they are selling out the SKU’s from the stores and inventories.
Depends on which carriers bloatware you want ROM’d onto it. You can “disable” bloatware, but you cannot remove most without rooting your phone.
Also it is the CARRIERS, that push the Android updates, not Samsung.
Not entirely true. AT&T has started Wi-Fi calling on a number of handsets and Samsung’s are some of the first. Tethering is only locked on certain rate plans, like unlimited data. Most rate plans and even pooled plans include tethering as an option.
