Q: Hi does the S20 ULTRA 512GB version is dual sim or single sim..

A: The S20 Ultra phone, regardless of memory, comes in 2 versions. The USA version is powered by Qualcomm Snapdragon, and the non US version is powered by the Samsung Exynos chips. The US version does not have the dual/hybrid SIM card tray that can either hold one SIM card and a MicroSD memory card, or hold 2 SIM cards. The USA variant has a SIM card tray that holds one SIM card, and optionally, a MicroSD memory card. My understanding is that the non USA versions are GSM only, so can handle 2 SIM cards. USA variants will have to support CDMA (Sprint or Verizon) carriers, so dual physical SIM cards are not supported in the USA version. Having said this, the Samsung website says that eSIM is supported on these phones, but they don't clearly state if both US and non-US variants support eSIM. The eSIM will give us the ability to use 2 phone lines. However, when I played with a S20 Ultra demo device at a Best Buy store, I saw there was no software ability to add a new eSIM. This ability is in the System Preferences -> Manage Connections -> Manage SIM Card section on the Galaxy Fold device, but the S20 Ultra did not have that menu item. So, my guess is that either the USA variant does not support eSIMS at all, or Samsung may add this ability in a future software update. This is a big miss from Samsung in my opinion, because I cannot migrate away from my iPhone 11 that works great with eSIMs and a physical SIM card. Sadly, the reporters who wrote online reviews for this phone from the announcement to the launch date only focused on reviewing the camera on this device and complained about lack of 120Hz refresh at high resolution, battery running out soon at high refresh rates, the steep price, and ignored to write about things that matter to the rest of us, such as eSIM support, call quality, speaker quality, face recognition speed and fingerprint sensor performance. I will have to evaluate these myself after getting a device in my hands for a few hours.

Q: Is it 12 or 16 ram ?

A: The 16GB ram is with the 512GB model from what I recall.

Q: Does the unlocked phone works with cricket?

A: yes it does, because is universal unlocked.

Q: Can I trade in my s10+ unlocked for a s20ultra unlocked and get trade in credit

A: You should receive a $600 BBY credit which can be used toward the device.

Q: Is this phone compatible with Cricket Wireless?

A: Hey there. If a phone comes unlocked, you have the option of which carrier's service is connected to the device. We would suggest contacting the carrier to ensure their services can be added. Thank you for asking this question. ^Kayla

Q: It supports 5G from metro PC. 100%

A: Hi Robin, Thank you for bringing this to our attention, and interested in whether the Galaxy S20 Ultra (Unlocked) works with MetroPC. In line with this, unlocked Samsung phones work on multiple networks. Also, it gives you the freedom to switch carriers any time and make sure that you have a compatible SIM card. Please note that sim cards must be compatible with the area's available networks. International calling, data services, and coverage vary by the network provider. Contact provider for details.

    Fast - Thin - Powerful

    #1 - the screen recorder is excellent & the editor is great. #2 - the ability to take UHD images that allow you to put on acrylic is pretty sweet. I got the 12ram | 128. You need to get a large sim card. If you take pics in 108mp mode and shoot in 8k, you'll drain quick. I'm a nerd, this thing is awesome and worth the 1.5k. Questionable: i have 12gigs ram, but it runs with 3.8-4.5 regularly.
