They wouldn't even need to drop 800's LTE. Remember that post-merger they'll have B12 and B71 available for 5G. Carving out an extra 5 MHz won't buy much, compared to the 20 MHz FD in 600.
I'm going to guess Sprint will cut PCS CDMA 12/31/21, with an extra year for 800. Could be EOY 2021 for everything depending on when the merger happens. The issue right now is that they still haven't launched VoLTE so who knows even how much traffic they can shunt away from CDMA with the phones that are in the field right now.
VoLTE works surprisingly well on an unsupported device at the moment. I've forced it on the Pixel 3 XL, which Sprint insists is not possible, and it works great. It ignores all the per eNB enable/disable settings that Sprint broadcasts, so it's working on magic boxes and in theory unlaunched markets. I tested the QoS on it today in a rush hour subway station where Hangouts messages were taking 30-60+ seconds to send due to congestion, and it worked flawlessly.

Honestly, I think whatever weird/non-standard(?) thing Sprint is doing to enable/disable it on a per eNB level is causing a lot of stability problems with supported devices, where it turns off and won't go back on, etc. Once that is overridden, it works really well, at least if you're in an area without 3G drops

I wonder what Sprints timeline is to shut down CDMA completely.  VZW CDMA is dead EOY 2019. ATT looks like they will kill HSPA EOY 2021.  Think Sprint would be in a great spot if they could do it in a few years. Once the market is full of 5G phones.  B26 could go down to 1.4MHz for LTE and add 5MHz for 5G. 

Any of the newer dual-band/tri-band equipment easily upgradable for 5G? At least not requiring a tower climb?

If the merger go through, they probably required to maintain CDMA for a while (1x voice) to support roaming from regional carrier.

I have a Pixel 3, and with Android 10 I noticed in carrier settings I can now enable VoLTE.  It seems to work pretty well in the greater Seattle area, with some dropouts occurring as I drive south of Seattle.  Is the Seattle market officially turned on for VoLTE?

Yes it is. Where are you experiencing issues? I'm from Seattle and pretty well connected with the network team there so I'm curious.

I drive from Mill Creek to Fife and back every weekday, and I've had some dropouts, regularly on the South Center hill for example.  Mostly south of Seattle although tonight a dropout as well on 405 in downtown Bellevue.  I have some SignalCheck Pro logs if you are interested.

South Center hill as in going south on I-5 from the junction of 405 and I-5? If so, that area is in dire need of a site; Sprint is the only carrier without one by exit 152. A while back, there were talks of colocating onto the monopole at (47.4332995, -122.2696476), although they never really happened and I'm not sure if that site is still in planning.

A dropout in downtown Bellevue? Where along the highway (exit number)? I live right around there and I've never had an issue...

I was traveling northbound on 405, just north of exit 12, SE 8th St.  There is a big retaining wall there on the east side, the freeway is kinda in a hole there.  Perhaps a cell was down for maintenance.

And yes, around exit 152 is where I drop (or lose audio but not drop) VoLTE calls regularly. CDMA calls seem to live through that area.

There is very good service along 405 in that area. A site may have been down for upgrades/maintenance.

Yes, that sounds about right. Sprint needs to do something about that area.

I also think there is a TAC transition there south of Southcenter too, if memory serves.  A transition area with a very weak signal and lots of noise from weak distant sites) would result in a lot of drops.  A strong localized signal far over the noise floor is required in this location for VoLTE calls.

Don't take away my 3G! It's the only thing that works decently at my apartment lol

You mean the band that it is using works in your apartment. If they replace it with LTE on that same frequency you should be fine.

      Official Tmobile-Sprint merger discussion thread

      By PedroDaGr8 · Posted

      Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!

      That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
