Here's something weird... I'm sitting down in Cochran, Georgia this afternoon miles away from the nearest Sprint tower I know of, and while I'm waiting for the right SIM to show up in my mail for the Pixel 3 XL I stuck my UK SIM (from Three) in the phone just to keep it active and see what I could find.
On the network list I'm seeing LTE network 311-490, which is a Sprint PLMN (but not listed as Sprint); it seems to be the same site as a T-Mobile site, as the signal strength bars on the "Choose network" screen are fluctuating in sync with each other. But my Pixel 2 XL (with a Sprint SIM in it) isn't connecting to that network; not sure if it's an issue of band support or just the network rejecting connections. I don't know if this is preparation for T-Mobile roaming going live, perhaps for only certain devices (i.e. VoLTE and data-only devices?), but it seems interesting.
Yup, no VoLTE I can confirm. I do have a question though. The last galaxy I had before my s9 was the s2 so I am not too familiar with how their baseband radio updates work. For the s9 does the baseband version change every time there is a system update regardless if there is actually new radio firmware? The reason I ask is because every security update we get the baseband version changes but the update size seems too small to contain radio firmware too. I used htc phones for the past 6 years or so and the baseband version would only change when there was new radio firmware.
“Following the Sprint 30-day trial, the Hulu with Live TV subscription fee will be added to customers’ monthly Sprint bills to allow for easy payments. We’re also giving customers a $5 per month credit (applied to their Sprint bills) for the first six months. After the six months expire, subscribers pay $39.99 per month.”
Apologies if this is a stupid question, but I've never really dabbled in cross-pollination device versions before myself at all to get up to speed on this: what actually qualifies as 'BYOD'? Does it have to be an explicitly unlocked version of a phone, or can you put the appropriate Sprint SIM into any carrier-origination version of the listed devices above and have it work?
