A:AnswerYes but if you want it to work without having your phone you need to buy it directly from your cell carrier. It would then come with LTE capability. You wouldn't need Blutooth or WIFI to use the phone if it is LTE capable.
A:AnswerFrom what I've read, it'll connect but with very limited capability. Do an Internet search. There are articles available that explain this issue more specifically.
A:AnswerThis watch does not have a SIM card slot and is connected to phone via Bluetooth and hence compatible with Android and iOS respective of operators - TMobile.
A:AnswerThey indeed carry both the bluetooth only model as well as the one with an internal sim card. The latter can have its own number as well as function via bluetooth.
A:AnswerCheck local stores for on-sale or return "Open Box" item. The Online price (vs. in store price) may vary. It is always good to check once in store to ask a sales person to double-check at the counter IF any watches have recently been returned. Sometimes the Best Buy website will not reflect this. My motto: "Don't ask; don't get!"
