Verizon Offering Domestic T-Mobile UMTS Roaming

Hi guys,

I think Verizon is now offering domestic HSPA roaming on T-Mobile on devices lacking CDMA.

While looking on Verizon’s international coverage map (https://www.verizonwireless.com/wcms/overlays/international-travel-coverage-map.html), I noticed 3G coverage in Curlew, WA which only shows up when “World Device (with GSM)” is selected. The coverage is not there on the “Non World Device (CDMA Only)” setting.

Upon poking around the source code, I found that map loads several coverage layers, including one called “directumtsamericas”. Upon cutting out all of the layers barring this one, I found that the map exactly matches T-Mobile’s HSPA coverage map. It is interesting to note that UMTS-only (non-HSPA) areas on T-Mobile’s map do not show up on Verizon’s map  

I know Verizon has offered UMTS roaming for CDMA-less devices on AT&T in the past. Maybe they are now replacing this with T-Mobile roaming?

EDIT: Premier sponsors can now view this coverage on the Ultimate Coverage Map.

    • Bloosurf is petitioning to deny T-Mobile's request for an STA specifically in their service area. https://wireless2.fcc.gov/UlsEntry/attachments/attachmentViewRD.jsp;ATTACHMENTS=Ghl9knTSFp8J4nVm1P9qL4541XR1gy58whH7Yyz0MwGs037gQrNV!-2042069078!-79842837?applType=search&fileKey=1297203795&attachmentKey=21718533&attachmentInd=applAttach Short read but pretty much they're saying that T-Mobile's operations in the BRS/EBS band has been interfering with Bloosurf's LTE-based WISP network and that this has caused them harm (lose customers, etc.) They claim that allowing T-Mobile access to all of the spectrum they bought in or near Bloosurf's service area would cause even more interference. To be fair they aren't wrong. They mention that in 2021 the FCC investigated and determined that T-Mobile was operating outside of its licensed spectrum band there. However, I get the sense that Bloosurf is just trying to stop a competitor from operating in their service area. Typically carriers work this kind of stuff out among each other. Here in NYC, 3/4ths of Brooklyn has 140MHz of n41 deployed and the southern 1/4th of it has 80MHz deployed thanks to an incumbent that leases the spectrum from the archdiocese. In spite of that there are no complaints of interference from NextWave in such a dense environment. Seems to me like Bloosurf just doesn't want to coordinate with T-Mobile and would rather complain to delay the deployment of spectrum for as long as possible. EDIT: It's not just their service area, it's a larger area surrounding their service area as well. Something's fishy about this request. 
    • Really cool blog post from OpenSignal giving a broad overview over the mobile network experience in NYC.  https://www.opensignal.com/2023/03/30/localized-analysis-reveals-huge-network-experience-gaps-between-mobile-users-in-the-us
    • Bit too early to tell imo. It's good news if Dish can stop the hemorrhaging. Q3/Q4 2022 they were able to stop the hemorrhaging. Their previous 6 quarters they lost between 160k and 350k subs each. Their next report will be interesting to see how they were impacted subscriber wise due to the hack.
    • I really wish this wasn't still so shrouded in mystery.  I see these phones available new on eBay (Boost locked, but again, I don't care) for $99, and would love to buy one of those and activate a Rainbow SIM on the $100/year plan, and I can't find a good answer on whether or not that is something that can be done, even if I drove down to Richmond to try to do it.  Don't really want to be out the $100 if they won't let me do it. - Trip
