Anyone using Sprint LG G8 on T-Mobile?

[Spetznaz24]

Got a great deal on an unlocked Sprint LG G8. Have a few annoying issues that are really bothering me.

I am unable to send and receive photos in text messages. I followed all the instructions to update the APN to be compatible with Tmobile.


Called T-Mobile and they put the IMEI number into their system and played with the settings on their end. They assured me that the photos in sms messages should be going through without issues.

I assume that there no chance to flash Tmobile LG G8 firmware on my LG G8? I was able to do that on my Galaxy S7 Edge. I would like to get wifi calling too. So many issues that are just annoying. One would think LG wouldn't mind letting people flash carrier based firmwares like Samsung does, especially considering that they are struggling with sales and need more customers.

I bought a refurb Sprint Unlocked for my GF to use on ATT. Just got it today and popped my TMO sim in. Didnt call them for anything, let the APNs auto populate and tested the following:

4GLTE+ icon comes up just like on my OnePlus 7 Pro, same # of bars/ signal strength

Calls - even with VOLTE enabled, the indicator says 3G when you make a call (assuming data goes to 3g like it would on sprint on a call but who knows)
VM- Stupid VM and Caller ID app dont work (sprint), but it dials to VM when you hold 1 key
SMS- works fine- sent a msg to a Verizon #
MMS- works fine- sent a pic to an email address
Internet- no issues , didnt do a speed test

Are you able to use LTE Band 71 on T-Mobile using your unlocked Sprint LG G8?

This has been talked about already in another thread but what you do is type ##data# and a menu pops up go tap on the apn and select view. On the top right you see the 3 dots click on it and reset that should do the trick. The reason for not being able to send picture is because the apn cant be edit so the apn is auto and is correct but not the mmsc part.

Tried this after manually entering a few variants of the Tmobile APN settings from Google, at least for me, didn't work. Not sure if other people have had better luck.
Seems like some of the MMS related APN config defaults to sprint urls. SMS, Data, and voice seems fine though.

so you tried going to ##data# and going to the apn and click on reset to default?

Yep, I get the sense that the fact the resetting the apn settings from the ##data# menu results in Sprint data populating into some fields and remaining uneditable.. is part of the problem. But can't find a workaround.

The reason I asked was because when i stuck my cricket sim in my sprint g8 the apn were automatic push to the apn settings and i could text and web but couldnt send mms pictures. So i went into the ##data# menu and looked at the apn setting which was correct but when i looked at the mmsc setting it was sprints like yours. After I reseted the apn to default i went back to look at the mmsc and to my amazement it was changed to aiowireless. after i was able to send pictures. Do you have your sim in there? Can you call tmobile to push the apns to you?

That's very good to hear. Were you able to test if 3G/4G HSPA(+) also works for data as it should? You should be able to find the option to use that instead of LTE by going to Settings->Wireless & Networks->Mobile Network->Preferred network type then select GSM only. Then browse the internet and maybe do a speed test--if you have at least 4/5 bars of 4G HSPA+ download speeds should be anywhere from 6-14Mbps. Myself and a few other people have been wondering since that's what you fall to if you don't have a good LTE signal so would greatly appreciate if you could check.

I'm having some disappointing results with the Sprint LG G8 on T-Mobile (Mint) in my home, and wondering if anyone has any experience that might help.

I was able to get data working without any issue after running ##data# and resetting the APN settings, but actual phone call functionality is a different story.

85%+ of the time I'm in my home I'm unable to place outgoing calls and when called my phone goes directly to voicemail. This is despite having decent to good T-Mobile LTE coverage. The obvious conclusion is that I'm getting spotty UMTS signal and/or the phone is not switching effectively between the two radio technologies.

To get any calling at all I had to switch the radio mode to "LTE/UMTS auto (PRL)" in the service menu accessed by *#*#4636#*#* but this also unchecks the VoLTE provisioning slider. When calling works anywhere, the signal icon changes from LTE to 3G.

try this TD-SCDMA/CDMA/UMTS. i noticed for some reason this works great. i was albe to receive every call. before that it was hit or miss.

I appreciate the reply! I tried this and it's about the same for me unfortunately (which is to say, not really working) I did notice that it says voice connection and data connection are both LTE, and I wonder if that's part of the issue.

I have another device that natively works with VoLTE and WiFi Calling on T-Mobile and it works very well in my home, it's just a shame this phone isn't quite there.

I can't make calls via lte or volte. it switches to 3g but at least now it always receives and makes calls.

1. Go to the default message app and click on the 3 bullets on the top right corner
2. Click on settings
Under advanced click on "Text messages"
3. Click on service number center and ensure it is the correct number for your carrier. If I'm not mistaken yours should read "+12063130004". If the number is different then change it to this one.

Found this on reddit. It reset the apn and get a new one. Now i am able to sent and receive mms.

Try ##SCRTN# on one device and see if it fixes it.

(It erases cellular programming and should reactivate automatically after a few minutes)

I have had so many problems with unlocked phones that are carrier specific. There is always some BS that gets screwed up. Unless its a Samsung where you can flash carrier or unbranded firmware I'm done messing with these carrier unlocked phones

 

[shadowfoxmi]

Any one manage to get WiFi calling to work? I have a Sprint unlocked phone on mint and wifi calling is the one thing I am missing.

 

[abced123]

im using the phone with Mint , TMO mvno, and mms send/receive fine. It used fast.t-mobilẹcom APN

 

[antintin]

So many people on mint I'm with them as well lol

Anyone figure out how to get VoLTE working on T-Mobile? I did find it in what of the hidden menu's I think it was under the ##DATA# > IMS or something like that but it was greyed out for me and couldnt change it.
