A:AnswerYes you can do it all!! My job calls for a lot of running around so the ability to not have to carry my phone has been a life saver and saves my phone from drops.
A:AnswerYes, the watch can support calls and text messages. I can be used independently from your phone, it will require it's own service plan. The other information you requested is not currently available.
A:AnswerI'm not sure. I bought the unlocked LTE option for my mom and she was able to connect it with Verizon. So, I would say yes but I would check with AT&T to make sure.
A:AnswerYes, & It Isn't Much Of A Difference - Just Faster & Newer (same as buying the Note9 or iPhoneX)...
For Females Such As You & Myself, The Rose Gold Galaxy Watch Is The Same Size As Our GearS2!
I'm Just Ready For A New 1, Which Happens Sometimes... (smile) (*_*)
A:AnswerYes, you just have to ask AT&T to active using an esim card. Not all AT&T store have them in stock. I had to call around and find a store that had them.
