A:AnswerYes, I believe it will. I have an unlocked version. Each carrier appapresently has their own version of 5G, yet some carriers are much more practical presently than others (according to my research thus far). From my research it appears some carriers are more 5G ready than others with claims of 5G service not all being straightforward and completely truthful. My suggestion is to read up on pros and cons of each carrier's 5G and don't rush on which one to decide on. That is the main reason I got an unlocked version phone. Doing this I can change carriers without having to change my phone.
A:AnswerYou'll have to pay the full amount upfront at the time of preorder, then once the phone comes in, "return" it, then use the gift card to help pay for it. Probably didn't explain it well, but short answer is that yes, it can be done, your local BestBuy should know the policy for doing so.
A:AnswerAccording to best buy and US cellular ad online and an email I got from both today (26FEB2020) you get a $200 Samsung credit to use. Now on how it is given or used that's a question for BestBuy or US Cell
A:AnswerMine did not. Only earbuds which came with mine were AKG wired for USB C input. I was allowed a $200 Best Buy gift card for my S8 trade in and a Samsung Shop gift card for $200 credit for buying my Samsung S20 5G Ultra as a promotional offer.
A:AnswerI have the G10+ and used it in europe with vodafone with no issues. My assumption is the newer one will have no problem. A way to check into detail is to check the carriers bands and then see if they align with this phone. The unlocked versions have very few issues.
A:AnswerYes it will work with Straightalk, and other Tracfone brands, specifically PagePlus, Simple Mobile, Total Wirless, Net10, etc. However, at ths time, 5G service is limited to T-mobile, Verizon, ATT, and Sprint.
