Not sure if this is the correct thread for these questions, but here goes...
I am trying to decide between getting a Sprint Note 9 and an Unlocked Note 9.
Besides the fact that the Sprint version of the Note 9 only comes in the 128 GB version, the other reason that I am considering the Unlocked version is that my Wife is currently on AT&T, and when her contract expires in February of 2020, we are considering having a joint Wireless Account.
So, it would be nice if my Note 9 could be on Sprint, AT&T, Verizon, T-Mobile, etc so that we could easily choose the Wireless provider that best fit our needs.
My questions are this...
If I get an Unlocked Note 9, will there be any way to get the Sprint Visual Voicemail on the phone?
Is there any chance that I would be able to to use WiFi Calling?
Would my current Asuron Phone

Insurance, through Sprint, cover the Unlocked Note 9?
Or should I just go ahead and get a Sprint version of the Note 9, and then try to sell it or trade it in after February 2020?
Please let me know your thoughts
Thank you
