As long as you want. I had a XS Max that I bought from AT&t several years ago. I kept it in the box for a full year before I opened it. I registered it and the warranty started on the day I registered it, not the day I bought it from AT&t

I funny think you will lose the card. It will move to another bank.

I applied months ago but I had too much credit card debt so they told me to pay down my debt to less then $500 which I did and pay my bills on time which I did and they would send me an invite in December.

I bough the Ultra 2 just for this reason. It goes just about 3.5 days. I last charged it in Friday at 3pm and I just charged it for the first time since then. It tracks my sleep every night. I use the Auto Sleep app.

Lol. I didn’t even check until you replied. People are stupid. Let them buy this junk.

I don’t see this selling very well. I will not be getting one or even trying it.
