AT&T roaming prioritized over Sprint coverage after PRL update.

Here's my multi-point theory on why Sprint isn't roaming on VZW for LTE:

1. Fewer Sprint phones have B13 than B12, and at the point that you're roaming on another carrier you want that low-band signal, most of which is still B13 on VZW.
2. VZW charges more for data roaming than AT&T does, and might not even let Sprint do LTE roaming. This is bolstered by the fact that e.g. FreedomPop uses AT&T rather than Verizon as the underlying network for its stuff...they wouldn't use it if it was expensive.

Also, add the PH-1 to the list of unlocked/BYOD phones that likely have the same firmware as the Sprint version, and thus get WiFi calling (though the PH-1 doesn't have Calling Plus; fingers crossed that I get VoLTE).

I've been in a few RF dead zones (yay hotels!) lately but have seen the phone drop down to native eHRPD rather than swap to roaming on e.g. T-Mo band 12, so my guess is that I won't see aggressive roaming to LTE until the VoLTE soft launch, and maybe not even then.

I'm guessing that number may grow a bit going forward as Sprint is using B13 in Puerto Rico and the USVI(?) via their partnership with Open Mobile.

The aggressive roaming has stopped for me. Yesterday and today, I was driving through a Sprint dead zone for 10-15 minutes. -110 1x (basically useless, you can't make a call on this stretch of highway, it drops almost immediately) and no evdo. My car has AT&T and had full service, but my phone wouldn't roam despite having no usable data.

Noticed this on the way to work this morning,  Appalachian wireless LTE with simultaneous Sprint 1x once again.

Happened to me before around Irving
