I don't believe that iOS 12.1 is all it takes, that is part of what is needed for phones other than the iPhone Xs and Xs Max. Those two model don't have iOS 12.1 and they can roam, if they have been updated.

On my iPhone XS Max, Bands 2 & 4 LTE shows up as Sprint native service on the device, but in Field Test Mode you know it's T-Mobile because the MCC MNC is 310 260. So it never actually states that it's T-Mobile except for the MCC MNC.

And yes, my phone kept jumping 5 hours behind and back.

Does it roam even with roaming disabled on the phone?
I saw someone say this on reddit recently.
 

When you say it shows up as native Sprint, isn't this because your phone sees the Sprint 1xRTT voice?

? It is what I have been told. The updates to all the phones, iPhones and Androids, that allow the new roaming is a staggered release. This is what it is.

Which update is it going to be in?

iOS 12.1 will allow more roaming.

My old 6s wouldn’t roam on T-Mobile either. Neither will my parents iPhone 6.

Soon. Wait for the iOS update, very soon.

Anywhere from 90-150ms. It does seem like I get higher ping times on this XS in general which is annoying.

I get 40 to 50 mS ping times when using OpenSignal's speedtest app, when not roaming.

90-150 mS when roaming is bad, if the signal is good.

What has been the ping/latency times while on T-Mobile?

So I fixed the screen on my iPhone 7 plus and now I can't roam on T-Mobile.  Went to the same supermarket this morning and the phone was as useless as it was before.  On the phone now with Sprint but it doesn't appear that are able to help me. 

You need to wait until iOS 12.1

Have  you done any speedtests while roaming?

Well, my worst dead spot is gone for data thanks to T-Mobile roaming. Now hopefully soon VoLTE will hit the Vegas market and iPhones, and I’ll be good to go. I wish I could say the same thing about my friends iPhone 6s’. They don’t have T-Mobile roaming. It’s odd.

Does the phone show 'Sprint' as the carrier, while it is on T-Mobile LTE?
Verified by the debug menu?

The iPhone Xs/XsM are the next phones to get VoLTE I hear, NV market is to launch today (Friday) do report back how that goes.

I believe the answer is simple. Sprint and T-mobile signed a roaming agreement and the agreement is to display it as a Sprint area. 

 

And Sadly our Xs's are weaker is signal capture..

If the phone sees a Sprint 1xRTT signal, it will display Sprint on the status bar, even when connected to TMO LTE.

I'm curious on this too.  How do i look this up?  My house is always terrible reception for sprint, but today I'm getting full signal. And only carrier here that's full signal is T-Mobile...

Dial *3001#12345#*

With the XsM, I'm not seeing anything different than with the 8+. I believe the XsM is 'sticking' to 3G a little less than the 8+, but can't be sure. Voice is fine.

Speed tests seem the same too, 85u/6d Mbps. I know of a few Gigabit sites that I will test with.

I thought the WiFi was for backhaul. Am I mistaken on this?

No.

But it will be used for different purposes.

So far so good. I'll be able to test more sometime today. I have an area I spend plenty of time that is on the fringe of Sprint CDMA.

Please do report back.
Ordered the Max model too. I have found the 1x voice performance on the previous iPhone 8 to be very good.

11 Mbps upload would be nice.

I have used Extended LTE and 3G on US Cellular, it isn't the fastest, but it works ok.

Usually speedtest on LTE is 3 up and down.

Great info, thanks.

I didn't know about the watch only enabling the cellular modem when the paired phone is out of range, that is good.

If on a plane, if I put my iPhone into Airplane mode, will that tell the watch to do that too, or do I need to do that on the watch too manually?

Can the watch connect to a WiFi network (if it is out of range of the phone), and answer/make calls on the watch using WiFi? 

If so, does it share the WiFi SSIDs/Password that have been configured on the iPhone, so the list is updated seamlessly?

Does the Watch with cellular (and phone out of range) use VoLTE for calling?

Does version 4 cell model have a better signal reception?

So I should turn on both data and voice roaming?

The only reason that I wouldn't have any roaming enabled is if I'm in a building on the edge of Sprint coverage, with the signal coming and going, it could cause it to use up the battery.

I always have roaming enabled.

If I turn roaming on, am I at risk of hitting the domestic roaming limit here in the DC area? This isn’t something I wanted to pay attention to or risk having service frozen/cancelled over. I have all the Auto Update over cellular functions on my device enabled.

Very soon, you will mostly just roam extended for data, which does not count against the 100MB(?) monthly limit.

Even now, if you reached the roaming limit, the data will just stop, no charge, no concerns.

With the  Sierra Wireless tech docs, they say they offer ota firmware updates.

Are they transparent?
How are they initiated?

Looking at pfsense, it has the support for that module via USB.

The Cradlepoint solutions seem more expensive.

This is really good, thanks.

Hopefully there’s a price drop this year as well for the iPhone X v2.

Does “Data Roaming” have to be enabled under settings to roam on T-Mobile?

I currently have voice/data roaming disabled.

You do need to have data roaming enabled to use T-Mobile's LTE data.
On the iPhone you need to enable voice roaming to be able to enable data roaming.

When on Sprint's voice and on T-Mobile's data, you will see Sprint as the provider on the status bar.

When on Verizon (or other like US Celluar)'s voice and T-Mobile's data, you will see Extended as the name of the provider on the status bar.
Soon, you will only be able to roam on Verizon (and others) voice, not any non-LTE data.
