Yes, in fact you can edit them and reload them onto your phone. Do you have a Mac or PC with iTunes?

Carrier settings sometimes update automatically. If you navigate to Settings>General>About and hover there for a few seconds, your phone should prompt you to update your carrier package if a new one is available. You may receive a popup asking you to update your carrier settings out of the blue if a high priority update is issued.

Yes. Canada is primary in that region and thus Sprint only has enough spectrum for 3x3 L800.

Hard to say. There isn't much duplex spacing so I'd say possibly although not certainly. I wouldn't be surprised if the lower and upper part of the T-band were FDD and there were non-paired chunks of spectrum inbetween. This is how the lower 700 MHz band is set up. For those unfamiliar, see here: I'm not sure if Sprint will be able to pick up spectrum here. Maybe someone else more knowledgeable can chime in here. SoLINC operates directly below Sprint, in the expansion band. Their 1.4 MHz LTE carrier is centered at 816.6/861.6 MHz. If they are interested in acquiring licenses, it will only be in their limited coverage area. As of today, they haven't made any public statements regarding acquiring spectrum.

It might be worth it to reach out to the network team in that area.

Those two carriers are contiguous. They should be merged into a single 10x10 L1900 carrier. Not sure why they haven't been.

That is likely a configuration error and will hopefully be fixed soon. There are no advantages to running two adjacent 5x5 L1900 carriers. They should broadcast a single 10x10 L1900 carrier with EARFCN 8640/26640.

8615 is pretty much always 15x15 L1900 on Sprint. The only other thing it could be is a 5x5 LTE carrier in the PCS C5 block, which should never exist. This is because if Sprint owned the PCS C5 block then they would broadcast a 10x10 C5+G carrier with EARFCN 8640.

The latter.

Seattle as well, although deployment appears to be just starting.

Sprint should have kept the 900 MHz spectrum they got from Nextel. That would have allowed them to completely dedicate PCS to LTE while leaving 1x/EV900 and 1x800 online today.

The T-Mobile roaming agreement doesn't include VoLTE. Sprint could do VoIP on T-Mobile LTE (similar to Calling Plus) although there may be reliability issues there. We will likely see VoLTE roaming on USCC, AT&T and other rural partners as their LTE networks mature.

VoLTE is live in the Oregon/SW Washington market. You must have a device issue.

Yes. The whole Inland Northwest market will turn on at once. 800 will need to be live throughout Spokane, along I-90, 385, I-82, etc.

Not coming until late summer at the earliest. Most of Washington state lacks a mature 800 deployment due to IBEZ issues that were only resolved a little over a year ago. This is a non-starter for VoLTE. The Puget Sound area is >2/3 800 complete. VoLTE should launch here first and then spread throughout the state. This is my home market so if you have more detailed questions, feel free to DM me.

Verizon's L700 Qrxlevmin values are very, very low. It is very unlikely devices on their network will drop LTE as a result of putting your phone in your pocket given you have any form of usable LTE when your phone is in hand. I would like to see Sprint drop their L800 Qrxlevmin value down to -128 nationwide. I made a post in the international forum a year or two about the TELUS network in Canada, when they only had 5x5 L800, 15x15 L1900 and 20x20 L2100 live. Their band management was absolutely phenomenal and I never connected to anything but usable LTE (or no service). Sprint could learn a lot for their example. Sprint has implemented ORNL to allow the network to push users from EVDO to LTE, although they seem to have halfassed the deployment. The ORNL transmit cycle is additionally usually configured to be so long that you might as well wait for the device rescan timer to push you back up to LTE. I've only experienced a good ORNL deployment in a few rare locations...I remember consistently reconnecting to LTE in Hawaii 10-15 seconds after dropping to EVDO.

I am aware. But as far as Sprint is concerned, it is going away.

In areas where Sprint holds the PCS C block, CDMA is usually thinned down to two 1x1900 carriers and a single EVDO1900 carrier. This allows for 4x4 MIMO on the LTE carrier. In areas where 1900 holdings aren't contiguous and a single L1900 carrier can’t be deployed, EVDO isn't usually thinned as much as Sprint can’t run two 4x4 LTE carriers. I can see EVDO being shut down by year end and Sprint running a single 1x1900 carrier in the L1900 guard band (in addition to their 1x800 carrier). Because VZW CDMA is going away in a matter of months, Sprint is working hard to get a VoLTE solution up and running fast. Supplementing L1900 bandwidth and stretching L1900 to its maximum range will be key to voice reliability as it will free up capacity on L800 for VoLTE in edge-of-cell scenarios (where Sprint currently struggles).

Interesting. I've never experienced that before but I'll let you know when I'm back. What device do you have?

What do you mean by dropping connections? I'll be back in that area in about a week. I can let you know what I find.

All customers with affected devices have been getting notices regarding this since January. The list initially only included select devices although it has more recently expanded to include almost all CDMA-only devices. CDMA activation and programming servers are scheduled to be shut down soon. VoLTE here we come.

Oops! I meant would not. I've updated my original post to say that.

There would be pretty much no incentive for Verizon to participate in a trade there as they have 20 MHz of contiguous PCS spectrum already (F+C). I wouldn't count on Sprint picking up the C block there.

B25 Wideband perhaps.

That would be correct.
