    I have an unlocked S20 5G Ultra (Model SG-G988B/DS) and can't get 5G anywhere on Tmobile. Confirmed 5G is available in my area with an Iphone12 on Tmobile. Is the unlocked phone the problem? Was looking for a way to see what signals my phone is seeing.

    My S20 Ultra 5G will not pick up 5G. Tested an iPhone 12 side by side and the iPhone can get 5G. Both the iPhone and my S20 are on Tmobile.

    My S20 is factory unlocked. Model SM-G988B/DS.

    Do I have an issue with my phone being unlocked?

    Did your Note 20 pickup 5G right away or did you need an update?

    They are both Galaxies and both similar with regard to 5G. I asked Mustang because I know he has 5G on Tmo. You might reach out to TMo to determine if there is anything you have to do but most people I know got it automatically. I'm on Verizon and the unlocked model requires an update but I didn't think that's the case with TMo.

    I had a similar issue with my unlocked Ultra on AT&T. It turns out that when I got the phone from Samsung, I just put the SIM card in from my previous S8 Active. Phone worked and I did not switch to a 5G plan immediately because coverage in my area was sparse. A couple weeks ago, I added the 5G plan but could not get 5G (including at the AT&T store next to a new iPhone that was getting 5G). Since I didn't purchase the carrier version, AT&T had no idea I wasn't still rocking the S8. Went to the store this weekend and got a new SIM card and AT&T updated the system to show my S20 Ultra. Now I get 5G.

    Could be that you have the international dual sim and using in the US , its bands might not be compatible in the US .

    THis is different, the OP purchased the wrong phone ie they purchased an international instead of US version.

    I had to do that on AT&T as well. They didn't change the sim but had to update the IMEI in their system to reflect the new phone. After that 5G worked perfectly.

    TMO gave me a new SIM (said I needed a new one for 5G) and made no difference. Still no 5G
