David Itgives you your heart beat, it has leds on the bottom, just like all the other watch heart monitors. Yes, all you do is take your SIM card and place it in the watch. Make sure the watch supports your wireless carrier radio frequency bands ...I have Rogers in Canada and it works fine.

David It does everything your smart phone does except for super amazing specs. like super megapixel cameras, hardcore gaming. but if you want to use it for smart home stuff like me so far it's been gold. I don't care for social media stuff but you can add that if you like. It's basically like any low entry smart phone. except you can take it on the go, and it's super small and goes on wrist and you don't need a big cell phone in your pocket to make calls. You have access to the regular Play store just like any phone(checked, plays store has Pandora). I've added alexa with all my alexa smart home gadgets (echo show5, echo 3rd gen speackers, smart locks, wink, etc). when you run video apps or high bandwidth apps continously 24.7. it does get toasty on your arm. I have been impressed with the wifi(working with my asus wifi6 router easily) and bluetooth 5.0 functinality(tried it with my Bob marly bluetooth speaker & amazon music app on the phone, sounds great, works great, not sure how hot it gets if left for a long time), I was expecting communication to be so-so but all it's communication features have been better than my sony compact performance phone (that was sonys high end phone like 3-4 yrs ago and has trouble with wifi 6 routers). I do miss some social media quick actions like sending or opening pictures in SMS or receiving them...it's kinda weird and awkward on this watch the way you send and receive them, might not display as perfectly and als
