Samsung Galaxy S4T L720T [Trimode] User Discussion Thread

Recommended Posts

Update received overnight and installed this morning.
Find the app in the app list, run it.

Intro screen,

terms of service screen,

e-signature.

Then you have to turn the toggle on, select and add each Wi-Fi network individually, and assign a 911 address to each of them.  (You can do this by a "current location" button.)

It also adds itself to the connections menu so you don't need to use the app icon.

New Wi-Fi calling icon

Seems to indicate you have set up the current network for the service. Blue and white icon in the systray.

In a call it says "Wi-Fi call".   A similar all blue icon displays above that text.

See image.

Signal check also indicates that it sheds you off the system completely. No cell connect. LTE disconnected, ehrpd via Wi-Fi takes over.

 

Seems to me that it is effectively making any wireless network capable of being an Airrave?

 

I'll have to play with it some more, but I suspect that since it is using ehrpd, it is also capable of voice/data simultaneously.  I'll see for sure when I get home again.

It appears Sprint is doing a slow roll out on this update. With how few S4T phones that are out there, I assumed this would be quick. Apparently I was wrong.

Yes. Verified. I connected to a call and could surf normally. I did notice a bit of audio degradation but it was still comparable to a normal rural call quality.

 

This should open the door to VoLTE.

I got the update overnight but every time I click on the wifi calling app, it goes into a device self service screen, and then says it can't activate and I need to take the device to the nearest Sprint store. Any ideas? I tried to restart but that didn't work. I also tried clicking on the app with wifi on and off.

Take it to a Sprint store.  I suspect something got boogered up in the install process.

I called customer service and they couldn't figure it out. I even did a factory reset and that didn't work either. I guess I'll have to make a trip to the store today.

I have a 720T S4..installed the WiFi Calling the morning it was released. It works perfect. You mentioned the WiFi calling failed to initialize. Most of the time, I have no problems, but every once in a while, the S4 won't register a WiFi. From what I gather, it depends on the WiFi router. I haven't figured out a pattern yet. Once I do, I will post.

After going to the Sprint store and since they had no idea what to do, they called a high level tech support. That person told the store employee it is a "provisioning" problem and it may resolve itself later but they couldn't provide any additional help. To be clear, as soon as I open the wifi calling app, I hit proceed and then it won't go any further. It tells me to go to a store or call customer service.

The provisioning should have happened right after the WiFi calling update was applied. Personally, I would wipe the S4 clean...have the network re-provision your device.

I did a factory reset. That didn't change anything. I wish I would've known ahead of time because it would've saved me 2 hours in loading everything back on my phone.

Type this from the dialer, before wiping: ##72786#

 

It resets your network settings and profile.

Did that too.

That means your account is provisioned. Its probably the router. Try a a few free wifi that don't require a browser login. Some routers need SIP enabled on port 5060 for wifi calling

They tried the router in the store and it didn't work there either. I can't even get to the screen to accept the terms and conditions. I doubt it even matters at that point.

Other than wifi calling not working for me, I also noticed the Sprint Zone app is messed up. It shows up as Mobile Zone with an Android character. When I click on it, it doesn't do anything either.

    • So, in summary, here are the options I tested: T-Mobile intl roaming - LTE on SoftBank, routes back to the US (~220ms to 4.2.2.4) IIJ physical SIM - LTE on NTT, local routing Airalo - LTE on SoftBank and KDDI (seems to prefer SoftBank), routed through Singapore (SingTel) Ubigi - 5G on NTT, routed through Singapore (Transatel) US Mobile East Asia roaming - 5G on SoftBank, routed through Singapore (Club SIM) Saily - 5G on NTT, routed through Hong Kong (Truphone)...seems to be poorer routing my1010 - LTE on SoftBank and KDDI (seems to prefer KDDI), routed through Taiwan (Chunghwa Telecom) I wouldn't buy up on the T-Mobile international roaming, but it's a solid fallback. If you have the US Mobile roaming eSIM that's a great option. Otherwise Ubigi, Airalo, or my1010 are all solid options, so get whatever's cheapest. I wouldn't bother trying to find a physical SIM from IIJ...the Japanese IP is nice but there's enough WiFi that you can get a Japanese IP enough for whatever you need, and eSIM flexibility is great (IIJ as eSIM but seems a bit more involved to get it to work).
    • So, the rural part of the journey still has cell service for nearly all the way, usually on B18/19/8 (depending on whether we're talking about KDDI/NTT/SoftBank). I think I saw a bit of B28 and even n28 early on in the trip, though that faded out after a bit. Once we got to where we were going though, KDDI had enough B41 to pull 150+ Mbps, while NTT and SoftBank had B1/B3 IIRC. Cell service was likewise generally fine from Kawaguchiko Station to Tokyo on the express bus to Shinjuku Station, though there were some cases where only low-band LTE was available and capacity seemed to struggle. I also figured out what I was seeing with SoftBank on 40 MHz vs. 100 MHz n77: the 40 MHz blocks are actually inside the n78 band class, but SoftBank advertises them as n77, probably to facilitate NR CA. My phone likely preferred the 40 MHz slices as they're *much* lower-frequency, ~3.4 GHz rather than ~3.9, though of course I did see the 100 MHz slice being used rather often. By contrast, when I got NR on NTT it was either n28 10x10 or, more often, 100 MHz n78. As usual, EMEA bands on my S24 don't CA, so any data speeds I saw were the result of either one LTE carrier or one LTE carrier plus one NR carrier...except for B41 LTE. KDDI seems to have more B41 bandwidth live at this point, so my1010 or Airalo works well for this, and honestly while SoftBank and NTT 5G (in descending order of availability) have 5G that's readily available it may be diminishing returns, particularly given that I still don't know how to, as someone not from Hong Kong, get an eSIM that runs on SoftBank 5G that isn't the USM "comes for free with the unlimited premium package" roaming eSIM (NTT is easy enough thanks to Ubigi). In other news, I was able to borrow someone's Rakuten eSIM and...got LTE with it. 40 Mbps down, 20 Mbps up, 40ms latency to Tokyo while in Tokyo...which isn't any worse than the Japan-based physical SIMs I had used earlier. But not getting n77 or n257 was disappointing, though I had to test the eSIM from one spot rather than bouncing around the city to find somewhere with better reception. It's currently impossible to get a SIM as a foreigner that runs on Rakuten, so that was the best I could do. Also, I know my phone doesn't have all the LTE and 5G bands needed to take full advantage of Japanese networks. My S24 is missing: B21 (1500 MHz) - NTT B11 (1500 MHz) - KDDI, SoftBank B42 (3500 MHz) - NTT, KDDI, SoftBank n79 (4900 MHz) - NTT Of the above, B42/n79 are available on the latest iPhones, though you lose n257, and I'm guessing you're not going to find B11/B21 on a phone sold outside Japan.
    • T-Mobile acquiring SoniqWave's 2.5 GHz spectrum  Another spectrum speculator down! T-Mobile is acquiring all of their licenses and their leases. Details are lacking but it looks like T-Mobile might be giving them 3.45GHz in exchange in some of the markets where they're acquiring BRS/EBS to sweeten the deal and stay below the spectrum screen. Hopefully NextWave is at the negotiating table with T-Mobile so NYC can finally get access to the full BRS/EBS band as well. 
    • Maybe. The taller buildings on one side of the street all have Fios access and the NYCHA buildings are surrounded by Verizon macros that have mmWave. I don’t think this site will add much coverage. It’d be better off inside the complex itself.
