Galaxy S20 Ultra 5G

Thanks for your inquiry. We don't have information about when it will be available. Keep visiting our website https://www.boostmobile.com/#!/. Any announcement will be first on our page.

You guys may already know this now, but Boost Mobile's site officially has the S20 5G on their page towards the bottom. Now when you click on "learn more" the bottom of that page you'll see it says, "This device is capable of accessing the Sprint 5G network, where available. Select plans only." It will be interesting if Sprint gives access to Boost to utilize its 5G network. However, since its the S20 5G the cheaper out of all the models it won't support mmWave. I don't think Sprint uses mmWave anyway. As for the S20 Ultra 5G, I don't think Boost will get it, but it would be great if Boost allows the unlocked model.

@Tarrahs12  I currently have the 10S+ working on boost! bought it unlocked & activated with no problem

Today, I received my S20 Ultra from Samsung, tried activating it online using my S10+ Sim and it says ICC is incorrect... Then popped in Sim into S20 and it said that my plan and S20 are not compatible... 🤔 ... I guess I will have to wait until morning to get this squared away...

Hello, @kings_fan32. Thanks for stopping by. You need to check the IMEI here and, if it passes eligibility, you'll be able to purchase a SIM card for your phone. 

@kings_fan32: Did you purchase a new SIM card?
