Q: Tried to buy the S21 Ultra 512GB online two weeks ago, but it was out of stock. Same sale offered this week, but *all week long* this item is "out of stock" -- how can you offer it for sale if you never have it in stock? When will you get this phone?

A: I ordered one in April and they said it would ship between 5/14 and 5/26 but now they have removed the estimated dates. BH Photo website also shows it as out ot stock and anticipated availability in July!!! Why all the ads and promotions if they have no supply? Hate being forced to switch to iphone.

Q: we buy this phone with the line, how much do we pay this line per month

A: It depends upon your plan with AT&T. On my plan, it’s $40 per month Cir the service, plus I have a few discounts, veteran, multi-line, autopay, etc. I have the highest plan through AT&T. Your monthly charge would vary based upon your plan and applied discounts. Calling AT&T should give you you’re exact amount based upon your plan.

Q: How is one saving 900.00 on the new Samsung S21 Ultra 5G by switching to AT&T? I see the price for it on your site as full price.

A: You trade in an existing phone to AT&T. The list of phones they will accept, plus what you receive is listed on their sales page.

Q: Is the Samsung Galaxy S21 Ultra 128 GB Phantom Black AT&T new ?

A: does my Samsung-Galaxy S21 Ultra 5G 128GB have a warranty on it.

Q: Does Samsung galaxy s21 ultra use micro SD cards to expand memory?

A: It does not, I have chatted with Samsung to confirm this and have seen this on reviews from people who have purchased the phone. Such a bummer, the expandable storage has been so great in previous phones.
