A:AnswerI'm feeling like this is faulty advertising on Best Buys part because I just got this watch for that very reason and I have not been able to find in any way that this watch measures glucose levels.
A:AnswerPurchasing the LTE version of this watch gives you the capability to use certain features of the watch without having to take your phone with you. You can receive text, calls and use some apps that require data (ie. Weather). This would require a data package from your cell provider. It is usually $10/ month. If you will always have your phone with you, thenyou can use it without a plan. You probably shouldn't pay the extra money and just get the non-LTE watch.
A:AnswerThere are several options to choose from as far as bands, from leather to metal depending on you taste. Best Buy and other websites will entertain your curiosity.
A:AnswerI ended up returning mine bc the battery wasn't even lasting 24 hours, but was getting down to 40% about twice a day. This was with disabling many features to try to preserve battery life.
A:AnswerI would definately ask Samsung. Please remember that an "LTE" phone has the capability of a separate phone line attached. This comes in handy if you forget your phone or you misplace your watch and it's away from your phone's connection. Hope this helps.
