A:AnswerUS version have one sim. International version may have dual sim. However, if you need to use warranty on the phone it may only be valid in Asia.
A:AnswerAccording to Samsung's website, it has 5G and LTE bandwidth connectivity (see attached photo) but it may vary depending on region or service provider. From my experience, it will automativally switch depending on cell tower capabilities. For instance, if you are in the city, it may automatically switch to 5G if 5G capable towers are available in that area and vice versa only on 4G in the rural areas where 4G towers might be the only towers available. Despite all this, you can still override a 5G connection by installing a force 4G app from the Play Store where you'll only connect to 4G if that's what you want.
A:AnswerVerizon HD Voice and Verizon Video Calling will not work with the unlocked model. I returned my unlocked one and got the Verizon model for this reason.
A:AnswerIt’s one physical SIM card and eSim. When you activate the phone is asks if you want to use eSim. Guess in the future physical sims are gonna be no more so they’re starting to normalize eSims now.
A:AnswerGet it unlocked to avoid headache later or take a chance to save money now and hope to god that everything works like you want it to later and avoid esims for as long as possible. Would you buy a locked car or locked house?
A:AnswerI didnt need to have them activate it, i took the phone unlocked and placed my old sim from previous device to the new s23 ultra at home and saved the activation fee.
