Interesting for carrier nerds

I know this concerns Verizon, but I found a couple of interesting things in the story:

 

- the Carrier line in About that says Sprint 13.0 is the version of the carrier profile/settings file

- you can tap on that line to cycle through your PRL version, ERI, NAI, and MSID.

- this file can be updated OTA. Presumably during normal usage it just silently updates next time you restart the device or whatever

- going to the About screen checks for an update

- apparently the carrier file can also specify network priority and routing settings - presumably this bug had the cellular interface set to a higher priority than the WiFi interface... Speculation is that it may have had the flag set to allow cellular when connected to WiFi, a feature pulled from the beta that was designed to prevent an interruption when the WiFi network was having issues by falling back to cellular data... But we don't know.

Wow, when you are on a tiered data plan with caps, this is a big deal. Ouch.

    • Yet another "Carrier" move: T-Mobile users have only now discovered sneaky change made in May
    • Went to Hurricane Harbor again this past weekend, this time testing Verizon and T-Mobile. In my testing, Verizon is now the fastest carrier, at least on the Hurricane Harbor sector. Despite it being pretty overcast on Saturday with temperatures in the mid-80's the park was at full capacity.  Verizon had 160MHz of n77 and T-Mobile now has 160MHz of n41. On LTE I was seeing speeds in the range of 50-100Mbps while T-Mobile's LTE on was completely swamped, barely crossing 3Mbps. While both carriers only have a single high capacity sector (facing Great Adventure, Verizon benefits from having CBRS deployed on all sectors. This is an extra 60-100MHz of capacity that T-Mobile doesn't have. Maybe when T-Mobile gets around to deploying their C-band we'll see a boost in speeds again to be more competitive with Verizon. On the 5G side of things, T-Mobile's speeds were just over half that of Verizon.  That said, neither carrier was slow and I had zero issue using Xbox Cloud Gaming on T-Mobile despite their weaker upload speeds and higher ping.  
    • I think the newer ones have signal bars on them. I took a photo of one in Red Hook a month or two ago that had the same design.
    • Well well, looks like we found one of the two Link5G towers that might actually have 5G. Notice anything different? This one has the same signal bars icon that the pole mounted 5G oDAS units have. It’s in Chinatown at East Broadway and Forsyth St. It’s impossible to tell what carrier it is, though.
