Boost itself is only going to sell the S10e, the discussion here has been on whether or not an unlocked version of the S10+ purchased through Samsung, or a Sprint version through Samsung, Sprint, or Best Buy can be used with Boost Mobile service. Yesterday (3-20-19), I was told that a proper SIM card has been ordered and will arrive within 3 to 5 business days, but I never got a confirmation email about it, so I'm antsy about it. They were extremely courteous to me over the phone, though. On other pages there are users that have gone through Best Buy and Boost Mobile customer service in order to get a working SIM card for their S10+; they also name part numbers for a BYOD Sprint SIM card kit, but I wanted to go through Boost to make sure it'll work on my account with them.
@Monsae for what it's worth, I received the Boost SIM card and it wasn't the same part number that everyone on here was using. The one I received was SIMOLW416TQ, but everyone on here is saying to use SIMOLW516TQ. I had already gone to Sprint and purchased the 4-in-1 SIM kit that has SIMOLW516TQ and used that to activate and it works great, so I'm not sure about SIMOLW416TQ.
Hello, @rafael6867. The Samsung Galaxy S10 Plus, specific model (SM-G975U1) has been authorized to be activated with us. Did you check the IMEI on our website: https://activate.boostmobile.com/bring-your-phone?intnav=TopNav:Phones:BringYourPhone?
