How exactly are you finding this out?
Was it from the February Pixel update?
How do you/we know when any of the combos go "live" on Sprint?
Thanks for the info!
As I've said in multiple previous posts, you need root with the pay version of NSG. That's the only way to get it on a Pixel.

It was either pushed in the Feb OTA, or Sprint pushed the config change. For what it's worth, the modem is identical in Jan and Feb OTAs (same sumcheck).

These are all "live", in that the phone will seemingly attempt to use them. The only additions here are domestic roaming combos. No international combos are present.

Interestingly, it has AT&T bands 14 and 30, but no 66.

No B71 for T-Mobile.

And it has B13 (Verizon) combos. Maybe a sign that Verizon LTE roaming is coming?

Can you share some of your speedtest results on Sprint? Are you in a Samsung market? Ericsson?

More importantly, is TDD-FDD enabled nationwide yet? Specifically Nebraska/West Iowa.

Thanks

I haven't really seen a speedtest get above 10 Mbps upload on B41. But on NSG it does show 2xCS UL if the signal is strong (otherwise it does 1 carrier with HPUE). NSG shows upload though in the 15-20 Mbps range, which is about the most I'd expect.

 

Samsung market.

 

I've seen FDD-TDD in Ohio, Pennsylvania, and NYC market. It's only used when B41 is too weak to use as a PCC, and it would switch to B25 anyway. The result is that B41 throughput isn't very good usually since it's so weak. I managed to get a speedtest with NSG running, and you can see B25 has 2 MIMO streams (rank 2, at 13 Mbps on one stream and 4 Mbps on the other). B41 is too weak to do 2 streams, so it's 1 stream (rank 1, at 3 Mbps on one carrier, 5 Mbps on another, and the third having no throughput)

Thanks for the info. Man that app really rocks. Too bad it requires root grrrrrrr!

FDD-TDD is supposedly live in Denver.

Im gonna grab a Pix 4 when funds allow.

I appreciate all your input.

It's easy to root Pixels. Especially if you do it as soon as you get the phone, before setting things up (I skip everything, even adding a Google account) since unlocking the bootloader does a factory reset.

NSG is tricky on the Pixel 4 though, since Google removed the Qualcomm diagnostics interface in the production build. You have to also flash the userdebug vendor.img from Google, which breaks some things in the February build (no dual SIM, you'll get no service and a "No SIM" error, and breaks active edge / squeeze for assistant). They all worked in the January build, so I'm hoping it gets fixed in March.

But worth it in my opinion for NSG. It's just such a useful app. You can find out so much information in LTE Signaling too if you know where to look (CA combos, the VoLTE enabled flag on an eNB, etc).

That's a big update.  I wonder if along the way the fix the problem where phone won't do LTE after losing signal due to a tunnel or an elevator getting stuck either roaming on TM, stuck on 3G or not having any data at all.

Looks like Carrier Services got updated for me today via Google Play.  I wonder if that's how update gets pushed?

Is there a consensus opinion (or even objective proof) about RF performance between the P3XL and P4XL, w/r/t holding or picking up weak signals?

I am interested in this too. Would like to know compared to the Pixel 2 XL.

My Pixel 4 XL gets noticeable better performance than my 3 XL. I somewhat regularly drive a route that would cause me to drop Sprint service (or go to 1x only) and roam on all my Pixels until the 4. The 4 holds LTE constantly, doesn't even drop to 1x or 3G. Now I haven't tested how VoLTE performs on this route, but I honestly haven't seen my 4 drop LTE yet.

CA combos for the Pixel 4 in a format that's easier to browse. Missing Verizon combos because I don't have a Verizon SIM with active service (inactive SIM connects to CDMA only).

https://cacombos.com/device?model=GA00677-US

Some combos might be missing because so many were listed that it was getting truncated in the message. Sprint took a few attempts to get all of the non roaming combos, and some roaming combos may not be listed. So att and T-Mobile may also be missing some (they maxed out the message size too), but at first glance nothing stands out as missing.

Same exact things are happening to me here in the Boston area. It's becoming very annoying. I resisted from toggling airplane mode the other day and remained roaming for over 6 hours in an area I know Sprint has had good LTE coverage for years. It also seems to struggle to pick LTE back up on its own once it drops back to 3G.. even when in areas of extremely strong LTE signal. Airplane toggle usually grabs LTE immediately, but we shouldn't need to do that.

Hopefully it's a software issue that can be resolved quickly. I have been trying to remember to report it through the My Sprint app, but not sure how helpful that really is.

This finally is fixed for me in the March update.  Amazing how quickly the phone gets LTE after a tunnel or elevator ride.

Mine seemed to be better too, but I wasn't sure if I was paying close enough attention.. it would be awesome if it was resolved.

It was a huge pain for me on Caltrain.  I'd be tethering, so I'd lose data.  I'd have to toggle airplane mode, then re-enable tethering.  And then wait for my laptop to "rediscover" my phone and reconnect.  Easily a minute of work would be lost while I wait for things to be back to normal.  And with 4 tunnels, it's a lot of work or a long wait...

Got my Pixel 4 XL yesterday. Pretty sweet phone! It will not connect to my Magic Box no matter what. Tried rebooting, toggling airplane mode, reboot magic box, etc.

I checked the PRL and it says "1". I updated the PRL and it still says "1".

Does everyone else's phone say PRL version is 1? How about connecting to the Magic Box? Any issues?

Edit: A day later and it connected to my MB but PRL still says "1"????

Yeah devices usually take a bit to find a MB initially.

My PRL is fine. f8f486ce016d09e2d6a8f28a7789bdcb.jpg

I'm also using eSIM. No idea why yours is like that. Seems like it hasn't actually downloaded the PRL or something.

PRL isn't just for roaming. It's for native CDMA too. If you didn't have a valid PRL then you wouldn't be able to use CDMA. It basically says "these sites are native, these are roaming, try them in this order and prefer this group over this other group".

You can also try the #*#*72786*#*# dialer code. That will wipe CDMA provisioning and force it to run again. But like I said, as long as CDMA works, I wouldn't worry about it.

Seems like the Pixel 4 XL LOVES to hold on to B41. Makes me wonder if the Pixel 2 XL actually supported HPUE.

It seems like the performance of the Pixel 4 XL > Pixel 2 XL.

Faster speeds, never falls to 3G, better radio performance overall!

I went into Data Settings on my Pixel 4 XL and noticed that it says CA Enabled Off.

I turned it to on and rebooted the phone and it still says Off.

Is this proper behavior for this phone?

My P4 (non-XL) has always shown that. Doesn't seem to have any effect.

      Just installed the 8.1 update on my Pixel.  Still no Sprint Wi-Fi / LTE calling
       
      But ... I did get the mandatory Google Search button added to my launcher.

      The rumor mill has fully geared up, so it seems time for a thread in which the potential HTC-made 2016 Nexus phones can be discussed.
       
      Rumors suggest two phones: a 5" device codenamed Sailfish, and a larger device codenamed Marlin. Both are thought to be produced by HTC. [There's also a report that Google is making its own phone, without an OEM partner--along the lines of a Pixel phone--but that report has been largely discounted.]
       
      Android Police has claimed it knows with 8/10 certainty some specs of the smaller device--Sailfish:
      Manufactured by HTC 5" 1080p display (~440PPI) Quad-core 2.0GHz 64-bit processor (model unknown) 4GB RAM 2770mAh battery 32GB storage (unknown if multiple models will be available, or even if this is the base storage level) 12MP rear camera, 8MP front Rear-mounted fingerprint scanner USB-C port (bottom) Bottom-firing speaker or speakers (unknown if dual) Top-mounted headphone jack Bluetooth 4.2 Any thoughts on these devices? The last several Nexus devices have been Sprint compatible; is there any reason to think these won't be? Any hints in regulatory filings? How is HTC's radio performance, generally? Will Sprint sell them directly, and even if they do, will it still be preferable to buy directly from Google?
    • By jefbal99
      Only specs I've really seen leaked are 5.7" screen and based on the unannounced "Mate 8" model.
       
      From http://www.breathecast.com/articles/nexus-2015-rumors-news-leaked-video-reveals-specs-of-purported-2015-huawei-nexus-video-30407/
       
       
       
       
       
       
       

      The Mate 7 had a 4100+mah battery, speculation is that this could have the same or bigger.
       
      Anything passed through the FCC for a US and/or Sprint version that covers the Spark bands?  I'm in the market for a new phone this fall and will be going off contract, buying a Nexus.
    • By nexgencpu
      Hopefully we can finally start seeing some user feedback. So far so good! it is without a doubt the best device ive owned!!!
    • By topdownat4
      Had not seen a thread for this yet, 
      I see some definite consumer advantages with Sprint's Network combined with TMob and Wi-fi.
      I have had many Nexus devices and I love my Nexus 6, although it is a bit big.
      The price is good for the service. ($20 / unl talk/txt, $10/gb)
       
      I hope the technical aspects work as they propose. I am a Google Voice Number user and love the "Any device" call capability and use it on my Tablet, Chromebook and phone. I rarely actually answer my Phone at the house. Answer the tablet or Chromebook.....
       
      I love Sprint's network, the upgrades they are putting forth and this Site, but if Project Fi works as advertised, it might lure me to sign on.....
       
      What are everyone's thoughts?

    • How do you get your Verizon SIM to connect to LTE without active service? Mine will only connect to CDMA.       Pixel 2 can do NSG, but Pixels require a licensed/pay copy of NSG to band lock. Other phones supposedly don't. Google disables Qualcomm diagnostic mode, so NSG has to jump through some hoops to get it working. On the 4 they don't even include the driver for it, and you have to flash the userdebug vendor image every month. Pixels are fantastic for NSG and logging, except if you need to band lock and don't have a license. No other way to lock bands.   A lot of people in the NSG community really like one plus phones. They support a lot of bands, and play well with NSG. But I'm not sure how good Sprint support is with their older models (ie CDMA).   If band locking isn't super important to you, you could get a Pixel 3a since they're on sale. They support dual SIM, so you can log on two networks at once with Cellmapper. SCP doesn't support dual SIM yet, and seems to report data for the active data SIM. Neighbors will show both SIMs though usually.   Sent from my Pixel 4 XL using Tapatalk      
    • I use NSG SCP and Cellmapper on a bootloader unlocked rooted moto g7 power unlocked. New for $179 on Amazon (many models but can give a link if needed). Used on T-Mobile and AT&T. ..
    • Wifi calling uses your internet connection to route just the the call, not SMS or MMS (thanks Sprint....). VoLTE uses the carrier's LTE data connection to route the call and allows for SMS and MMS at the same time. When on a wifi call, you can still receive SMS and MMS but not if you have a shit cell signal (doesn't even matter if you are on a call or not, with a shit signal you will still have trouble anyway). The Pebble is used to boost your cell signal so your SMS and MMS will be more reliable (and your LTE data connection). For actual internet use, you are correct, you can just use your wifi.   Femtocell for the Home For the consumer, Femtocells can be used to transform an already existing internet connection into useable cellular service. It may sound counter-intuitive, but there are many people in the United States who have access to high-speed broadband but who are unable to make phone calls from anywhere inside their home, and for people facing that situation, femtocell technology may be their best option. Here’s why: Femtocells operate like a tiny cellular base station, literally tiny, at about the size of a cordless phone’s base station, and can be easily attached to your home internet network modem. The Femtocell then transforms your home broadband connection into a usable cellular signal that can be used to make phone calls and send and receive SMS text messages. In a scenario like this, a femtocell system may be the absolute best option, especially for consumers who are unable to utilize Wi-Fi calling with their current contacts and cellular provider. Most individuals, especially those who run a small business from their home, still require a reliable cellular signal in order to handle their affairs, and a Femtocell network can provide 5 bar connectivity from anywhere within the home. Unfortunately, this cellular connectivity does come at a cost. Because the Femtocell uses the existing broadband to create the cellular signal, there can be a noticeable loss of broadband speed in certain situations where phone calls and web browsing (especially uploading or downloading) behavior is occurring simultaneously. However, if your home office broadband connection is currently 50 Mbps or faster, then your internet connection should remain perfectly steady, even if you decide to use both at the same time.
    • Thank you all for the advice! Luckily for me, I am covered as far as SIMs go; I was just looking for suggestions on a cheap android. I'm able to get a really good deal on a Pixel 2 - do NSG (is some other form of band locking)/SCP/Cellmapper run well on those phones?
