Forgot to post this Speedtest I took earlier in Brockport, NY which is 20min west of Rochester and was founded along the Erie Canal. I have done many speed tests over the years dating back to fall 2014 when I first got my iPhone 6 and Sprint had begun to really expand 4G. With that said, it was not until this Speedtest that I had topped 300 mbps down or over 20mbps upload. This was done on my iPhone 11 Pro Max, which is obviously an Advanced LTE device. I still do not know for certain what today’s announcement will be but New T-Mobile is already surpassing my expectations. Just think how much faster this Speedtest could have been had my iPhone been packing a Qualcomm X50 modem as opposed to the Intel XMM 7660 modem. Sent from my iPhone using Tapatalk
$5 says it isn't DSS. They have enough spectrum in bands 71 and 41 to not need it, and if they're going to climb towers it'll be for adding n71 and n41, neither of which are densely deployed right now.
My bet is something about improved low and mid band 5G deployments, with a kicker of opt-in T-Mobile primary network conversion for anyone on Sprint who wants it...and opt-in account conversion (including SIMs) for a subset of plans.
Maybe new plans on T-Mobile's side that are at least as good a deal as Sprint's published unlimited plans.
