+4 pts“No. Fenix doesn't have either SIM or eSIM support so it can't make phone calls without a phone. Garmin's LTE is not for that.”

r/Smartwatch
ViewTop Criticism
+1 pts“When I bought my T-Rex Pro 3 years or so ago, the field was much less crowded; no Alpha Gear and Carbinox junk. I did the research and thought that Amazfit was going to be a real player. Granted, they are a legit brand, not in the bottom, but still reaching for Samsung, Suunto or Google status. They lost me with their (lack of) customer service. My watch failed at 22 months and they offered no solution of any kind. The good press alone that I would have given them, along with real loyalty would have been worth more than the cost of replacing it. I would have been happy with a free repair, but nothing was offered. I put Apple, Garmin and Samsung at the top level for experience, proven product viability and they're not going anywhere anytime soon. As I said, I don't do Apple. Garmin is a price point above where I want to go. I know they have cheaper models, but I'm not comfortable buying anybody's 'affordable' models when the flagship is nearly $1K. Even Samsung has SO MANY models. They don't seem to replace watches, they just make another model in classic and blah blah blah. The easiest is to get one to match your phone, provided your phone maker makes a watch. But I just don't like the Pixel watch 3, for battery alone, odd styling not withstanding. I think I'm leaning towards a Suunto, if I can figure out the right one...”
