Hotspot for S5 on T-Mobile - Android Q&A, Help & Troubleshooting

I just ported my S5 over from ATT to T-Mobile. I got everything else to work, but the hotspot. I rooted the phone, tried third party hotspot apps, but still can't make it a hotspot. Some of the apps bring up the invalid SIM error, some say the hotspot started, but it doesn't show up. (I don't have it set to hidden).
T-Mobile TS says it is hard wired into the MB to use ATT network and require an ATT SIM. He says the only options are a standalone hotspot or buy a new T-Mobile phone.
My phone specs below.
Any other tricks to make this work?
S5 SM-G900A
Android 4.4.2
baseband ver G900AUCU2ANG3
build KOT49H.G900AUCU2ANG3 APR 16 2014
kernel 3.4.0-964333

Verizon Moto E (2015) 5.1 with GSM Tethering? Has it been done?

I've been very happily using my Verizon prepaid Moto E with the trick to unlock usage of the GSM radio found elsewhere on this forum. The only thing I can't seem to figure out, is how to make the built-in tethering function work. Since I can't root this device (VZ version hasn't managed to get an unlocked bootloader, it seems), I'm stuck using the built in functionality. I tried adding "dun" to the APN type settings, but that didn't work.
Activating the hotspot allows other devices to connect, but they can't "see" the internet. I've heard that this SIM I'm using (freedompop) can be configured to work in phones like the BLU R1 by just adding DUN to the apn type string, but it seems to make no difference on here. I can't confirm if the SIM works with tethering because I don't have access to another unlocked phone at the moment. Can someone help me verify if the problem is with the phone or the freedompop service?

Dual SIM: One for Wi-Fi hotspot, the other for all other apps?

I am the proud new owner of a Motorola G4 Plus 32GB running Android 6.0.1, there seems to be an update available, though it will not update from here as there is no Wi-Fi, therein the reason for this post.
My personal Vodafone SIM that has 4G most of the time, but with a 15GB limit, and I have a work Three SIM, that rarely gets 4G, but I have confirmed with my employer has no limit.
The SIM settings have an option to select which SIM to use for mobile data manually, but what I would really like to do is use my work SIM for when I tether my laptop to my phone using the Wi-Fi hotspot (which is often where I live at the moment), and my personal SIM for all other apps on my phone.
Anyway to achieve this?

H831 - No LTE option in network mode

Hey everyone
I have the Canadian variant of the LG G5 (the H831) and I have no LTE option in network mode.
I bought this phone from WIND Mobile (now Freedom Mobile) and it seems like they Disabled the LTE functionality for some reason.
I was wondering if there is a way to enabled it?
I inserted my SIM in my friends phone (same model but with Rogers Wireless) and the phone downloaded the APN settings from Freedom Mobile.
That did not work at all and the phone was stuck on 3G just like my phone.
I heard if I install the firmware from another provider, it might work. However it seems the APN settings from my provider are causing the LTE option to disappear from network mode.
Lastly, I accessed the service menu by dialing a code in the dialer and I was able to enable LTE.
However, I was not able to make and receive phone calls.
Did anyone here have success enabling LTE with this model or similar?
suggestions are greatly appreciated!

Models of GSM E2 without Hotspot network check?

Have been using an OEM Motorola version of the XT1527 on AT&T, and since it only has the base wifi hotspot app installed, I can use it no problem since there is never a network check for a hotspot subscription etc.
Now I recently tried setting up both an AT&T branded XT1527, and also a Verizon branded XT1528, and was able to successfully get them 4G enabled, but since they both use a custom version of the wifi hotspot app, they denied enabling the hotspot.
I understand that once rooted, you can edit some files and change the config to not do a network check. Trying to avoid rooting if possible though, and see if there are other variations that may work out of the box.
How about Cricket or Cingular branded XT1527, does they have the same hotspot restriction? Any other GSM versions which may just be rebranded with all OEM software like my original one?

Question Voice over Wifi?

So I got the phone and it's working really well. My biggest issue is the lack of VoWifi. I called T-Mobile and the tech felt it should have it.
When I dialed *#*#4636#*#* (I think it's that), VoWifi is greyed out. Is there any way to use ADB or anything to force-enable it? There's no way, with the LTE/5G bands it has that it cannot be enabled on T-Mobile...

It can be related to your provider or it's SIM settings. I use Dual SIM. My Vodafone (NL) in SIM bay 1 has the WiFi-calling option. My KPN (NL) in bay 2 doesn't have it.

You will only get wifi calling on Google fi on xperia 1, xperia 1 ii and xperia 1 iii. I have used all three phones on tmobile and it doesnt get wifi calling but on Google fi they do.

That's because Google has its own WiFi calling implementation, not using VoWIFI. It should work on just about any device.
I am able to get VoWIFI on T-Mobile after flashing Sony's Developer Binary (for the Xperia 1 ii), but unfortunately that one comes with some other unacceptable compromises (like no task switcher). Anyway the attached screenshot shows the service screen (dial *#*#INFO#*#*) on T-Mobile with this firmware. T-Mobile WiFi calling also works with even more out-of-fashion phones like my Nokia 9 PureView, so I would say this is definitely a Sony firmware issue.
In turn, the WiFi hotspot function does not work on Google Fi on any of my Xperias (1 ii, 5 ii, 1 iii). The client (e.g. laptop) connects to the phone and gets an IP address, but can never reach any website. It works fine with other phones (Nokia, Samsung,. ... and even the same developer image), and it works fine also with the Xperia on T-Mobile and AT&T. I suspect some iptables/firewall incompatibility between Fi and Sony's stock firmware.
I returned my phone back to sony because of missing vowifi.
T-mobile expert said its fully compatible but Sony expert said All Sony Phone dont have vowifi (disabled by software)
So I bought Xperia 1 III (along with a prepaid 3HK SIM card) when I was traveling in Hong Kong.
I inserted that 3HK SIM card to Sony phone, the Wi-Fi Calling was an option in the setting menu.
But after I returned to US, I swapped an Ultra Mobile SIM card to the Xperia 1 III, the Wi-Fi calling option is gone.
Before that, the Ultra Mobile SIM card worked perfectly on a Samsung Note 9 (also Hong Kong version) with Wi-Fi calling enabled. So it looks like it's a software problem.
Tried Google Fi SIM card, I was able to activate Wi-Fi Calling in Google Fi app, but not in phone setting menu.
T-Mobile VoWiFi is incompatible with the stock Sony firmware. You can get it back by flashing one of Sony's developer binaries onto your OEM partition (for "open devices" like the Xperia 1 ii and 5 ii but not 1 iii); however this also makes the phone not really suitable for day-to-day use (for instance, no "recent apps" switcher).
FWIW, T-Mobile VoWiFi works great on my older Nokia 9 PureView, which is definitely not a "known" device as far as T-Mobile is concerned. So the issue is limited to the combination of T-Mobile USA and stock Sony firmware. (Of course, VoWiFi also does not work on AT&T, but that's expected since they only provision AT&T-branded phones).
WiFi calling works on Google Fi, because they use their own implementation (not VoWiFi). Alas, WiFi hotspot functionality is broken on Fi - there seems to be something like a firewall/iptables incompatibilty between Fi and the Sony firrmware. The client (e.g. laptop) is able to obtain an IP address and ping the phone, but is not able to then connect to the Internet. (This, too, is fixed with the developer image above).
FWIW, as a workaround, you can install the T-Mobile DIGITS application and enable this feature on your account to make calls over WiFi. The only caveat, as I learned today, is that this does not let you make international calls. :-(

What does developer binaries do? What can you achieve with this and how do you install it

They are actually just meant to bring back some of the original Sony functionality (e.g. camera) on top of a plain-vanilla AOSP build. For instance you can build and install AOSP 12 and then flash this image to the OEM partition. Won't give you Google Play services though, so not really useful for most people.
However you can also flash it on a stock Sony firmware. (Just apply step 7 in the AOSP instructions above, without doing the rest). Fixes some issues, including VoWIFI on T-Mobile and WiFi hotspot on Google Fi, but unfortunately the recent apps switcher is then gone.
Only available for "Open Devices" like the Xperia 1 ii and 5 ii, but not 1 iii.
I know this is a roundabout solution, but it worked for me:
Port your number(s) to Google Voice. This will end your current wireless subscription.
Sign up for a new wireless plan, with new numbers. (*) If you order a new plan online, it's a good idea to do this first so that the SIMs arrive ready for activation before you start the previous step.
Set up Google Voice to forward your calls to that number. Or better yet, install the Voice app on your phone - you can redirect both inbound and outbound calls via this app/service. (I.e. you can use the native dialer to make Voice calls; however for text messages and voicemail you need to use the Voice app).
Optional: In the native phone app, block all inbound calls directly to the new number (remember, your primary one is now on Google Voice).
This also gives you the ability to send/receive calls, voicemail, text messages on a web browser. In other words, all of this is essentially a roundabout way of getting functionality similar to Google Fi; but remember, Fi's hotspot does not work on the Xperia.
(*) Apparently if your carrier is T-Mobile, cancelling 3+ lines and then signing up for 3+ new ones won't give you the same discount as the original signup. According to a local T-Mobile store rep I talked to, if you cancel and recreate service within 90 days, the system thinks you are trying to somehow cheat on discounts. Weird -- I ended up going (back) to AT&T for this reason. You may also consider T-Mobile MVNOs such as Mint Mobile. (**)
(**) Oddly enough, in addition to better overall coverage, I get much higher download speeds on AT&T LTE/LTE+ compared to T-Mobile 5G (NR/NSA) - even in a place with full bars on both carriers. I did a test today with two SIMs in the phone - on AT&T I got 100 Mbps down on first try, whereas on T-Mobile the best I ever got (20+ tries) was ~30 Mbps down; typically 15-20. Not sure if this is another artifact of the Sony firmware, YMMV.
------
Course, if you only need to make domestic calls while on WiFi, T-Mobile DIGITS is the path of least resitance.
