I received my Le max 2 (x829) about 5 days ago hoping my carrier would "support" it. Turns out US Cellulars bring your own phone style plan is incredibly limited, and after about 3 hours on the phone I was told that based on the IMEI number I had given them, US Cellular's (USC) system wouldn't be able to support the phone.
Side note right there - I did notice that part of the "rules" given to me on this were already broken on my Current USC phone and that Both the x829 and current phone share some similarity in IMEI number rhythm (maybe nothing but wanted to note it) IE *405033* on one, and 454050** on the other.
Found some time to research today and have found several XDA members noting that they have their x829's working on T-mobile, even T-mobile through Straight Talk. However, when checking "phone comparability" with either one using the IMEI # that all companies want to know atm I'm given an error.
So My question is thus: How did you; a X829 owner get your phone to work on your desired carrier? It seems AT&T and T-mobile seem to be the go to on this which I'm fine with.
A side question would also be: could I use "xposed" to change the IMEI to something my current carrier would "recognize" / was this what every one else has done?
Isn't US Cellular CDMA? For the Le Max 2 you'll need a GSM network.
I just received my x829. Out of the box VoLTE and WIFI calling worked with T-Mobile (on all official EUI 16s roms). I currently use the MADSURFER and both wifi calling and VoLTE are working.
All I had to do was pick up a nano sim which I activated via phone. I bought the Fire HDX 8.9 SIM from amazon for $4.00.

US Cellular is listed as CDMA, but all the research I've done before going with the Le Max showed that other GSM only phones like the ONE plus 3t would work on the network based sole on the phones bands support by the phones hardware.
I have plenty of Nano sims thanks to the Straight Talk "phone kit", infact both the At&T and T-mobile ones are in the phone atm. I do appriciate you re-enforcing the notion that VoLTE and Wifi calling work (which would be to my benefit where I live) my fear is that calling and trying to activate the sim will lead the "rep" to ask for the IMEI and again tell me wont work.
@leptdre i'm very leery to try things with out a further explanation, kind of a side effect of the college days.

US Cellular uses the CDMA band 20 (3G) 800MHZ. see: https://www.frequencycheck.com/carriers/u-s-cellular-united-states
I was thinking that the menu was for enabling Band 20 for LTE, but I was wrong. In fact it says: China Telecom's CDMA , china telecom uses CDMA band 20 (3G) like US Cellular.
https://www.frequencycheck.com/carriers/china-telecom-china
I think if you can get US Cellular to activate the service, with this option checked : *#*#9439#*#*, you can get your phone up and running.
I activated mine on Tmobile. Bought a sim from them and activated it online, used the 1st imei number on box, there's 2 imei numbers I assume 1 for each sim slot. After punching it in it knew I was on a LeEco Le Max 2. Rebooted phone and wifi calling appears. Also wife and son have same phone on T-mobile but already had nano sims so they just moved sim to their X829 and that was all they needed to do.

T-Mobile and AT&T are GSM carriers, which means that the sim is the only identification module.
US Cellular, Verizon, Sprint are CDMA carrier, the identification must come from the phone it self. The sim is only use for 4G LTE because 4G uses a standard relying on GSM to identify the customer.

I had a Straight Talk kit from an earlier attempt to use a Zenfone 2... the rep with strait talk wouldn't "force" activate the sim for my area because "no coverage". Apparently my city/town where I will use it the most doesn't have enough coverage From At&T or T-mobile to warrant being able to transfer my number from USC. Going to try "re-upping" the AT&T sim A user on another thread has noted that @ stock on EUI rom wifi calling was still available with At&t.
Edit:
https://www.amazon.com/Fire-HDX-8-9-Activation-T-Mobile/dp/B00L8BYGJQ - decided to go with that as xlCashlx did and try t-mobile... so far out of all the reps I've delt with over the last couple of days, t-mobile's has been more forth coming with information than any of the others.

So did anyone tried to use it with Verizon? According to willitwork site should be a go, but someone needs to confirm. For example I am using the Zuk Z2 from China and the 4G on VZN is working like a champ.
T-mobile here. When my x829 arrived, I simply pulled out the sim in my Moto G4 and immediately had service on the le max 2. Didn't even contact T-mobile.

Did it came with the stock rom or some sort of custom one when you bought it, thanks?
It came with the EUI factory rom by letv. Now that I think about it, I never actually tested TMO on that factory ROM. My wife has the x820 and I have the x829, both on TMO and both on different roms.
However, I have flashed the small EUI rom with no problems, plus you can find other user's experiences with TMO on stock EUI and everything I've seen points to good compatibility.
I'd recommend looking thru some of the threads on slickdeals for this phone. There has been a lot of discussion on different experiences with US carriers, mainly from a budget/value perspective. I'm on the walmart TMO $30/mo 5GB LTE plan (pay as you go) and really like it.
https://slickdeals.net/newsearch.php?src=SearchBarV2&q=le+max+2&searcharea=deals&searchin=first
To answer my own question and to advise everyone else that lives in the US and is planning to use the phone on Verizon network, you need to look elsewhere. Let me elaborate, I am getting LTE on the phone right after inserting the SIM card, but voice is not working no matter what, I even made a trip to my nearby VZN store to make sure that they dont have to go and white-list my IMEI or something. To put it in a more polite words, they declined to do anything, even after the fact that I have a corporate SIM that my company pays hundreds of thousands of $ per year to VZN for all the subscribers we have internally, on top of that I had my Zuk Z2 to prove them that, other phones that are not VZN "approved" can work with no problem with both LTE and voice. The last comment from the representative was that there are loopholes and some not approved phones can work, duh, I had the evidence with me, and again they refused to add the LeMax 2 IMEI to their "good" list.
So if you are planning to buy this phone, consider the fact that you will only be able to use it on ATT, T-Mobile and the rest of the GSM providers in the US.
Hi All,
Just wondering if there are any AT&T users out there that have the Le Max 2 X829, and have volte and wifi calling working? Currently, I am running [7.1.2][OFFICIAL][VoLTE][ Resurrection Remix. Everything works, only I am not sure how to get WiFi and Volte working over AT&T. Any input would be appreciated.

I believe the problem might be your apns. Im on metro wasn't getting volte. Back a backup of your rom. Edit your apns, just change something in them and save. They should dissapear. Do that to all your saved apns. Than you should have a different set of USA apns pop up.

T-Mobile WiFi calling
Hi all. I have a quick question... I flashed my LeMax 2 (X820) with Lineage 14 version. So far so good but there are two questions that I have... In LOS 13 there was a theming built in. Was it removed from LOS 14? And the second more important question...I see posts about WiFi calling working on Tmobile...is it based on the stock firmware of LOS and if it is LOS, is there any specific way that I need to enable it? I don't see it in the menus
Which ROMs have both Wifi calling and volte settings both integrated? I see a lot of [VOLTE] in the titles for these ROMs, but not much mention of Wifi calling. I'm far more interested in integrated wifi calling first.
I switched from AT&T to T-Mobile last week. So far I love the coverage! I've only been able to get WiFi calling to work with EUI. And even then, its sketchy. Has anyone successfully gotten WiFi calling to work on other ROMs besides EUI? I personally cannot stand EUI, and would rather use LineageOS, RR, or something similar.
(US ATT and T-Mobile)
I have this phone, but only by way of ATT telling me my non-VoLTE 4G LTE phone would not work after ATT shuts down 3G.
I move over to T-mobile recently. All works ok. I then activate VoLTE on the Mi. All works ok.
But I had to call a T-mobile rep regarding my iPhone, in that conversation I asked if VoLTE was even needed, and he tells me no, that T-mobile will still do voice data w/o VoLTE enabled.
So, VoLTE is a feature of LTE and implemented on 4G/5G, and really has nothing to do with 3G being shut down.
There's so many sites stating you "need" VoLTE to keep making voice calls after 3G is gone. This is not true.
"As 3G is switched off, you need VoLTE or HD Voice support to make calls on 4G networks."

As I understand it you need 3G for voice.
You may be able to use internet service but without VoLTE, no phone service.
If the device is not white listed it likely will not be able to have phone service as your link states.
I have straight talk with AT&T sim, I was using my Black Shark 3 pro which has volte and all of a sudden Friday at midnight, no data or phone service. At that time my bs3pro has been having heating issues, so i moved everything over to my redmagic 6 which has volte. I noticed my sim was locked in apn, totally different apn info than my bs3pro, so i called support, since everytime I tried to make call it blocked calls and sent me to support. The CS person did something on their end, had me restart phone, then service was back to normal and been fine since.
If your service provider only provides 4G infrastructure like mine... then you need VoLTE otherwise no phone calls. They are new and never had any 3G and below infrastructure. I tried making calls .... it doesn't.
My service provider annoyingly doesn't provision volte for my volte capable handphone (this makes my eyes swivel) but does provide an app to support phone calls without volte.. but it chews up battery
@roger_rex
But T-mobile (US) runs 4G and 5G, but # of towers with 5G not as plentiful as 4G. I connect 4G LTE most of the time, voice & data works just fine. T-mobile rep told me it will work w/ or w/o VoLTE enabled on phone. The APN used is the "fast" APN one.
A 5G connection does not negate any benefits from using VoLTE.
Was on phone again today with a T-mobile "tech team supervisor" for a service issue (they accidentally turned off one of my SIM cards). I then asked about VoLTE, he tells me it's no longer needed on T-mobile 4G or 5G LTE, but using VoLTE will still work. He seemed to suggest VoLTE not needed at all on 5G because the speed of the wireless can carry both voice and data fast enough. He also hinted their 4G can do the same.
If you have a fast pipe then you really don't need a side channel for the voice.
But duly noted, everything technical that I have read about on VoLTE, using that feature gives better voice call on any LTE that supports VoLTE. The supervisor also mentioned that "VoLTE" will basically go away at some point.
Pretty sure on 4G LTE you need either VoLTE capability or a 3G connection for voice calls.
Redirect Notice
4G VoLTE will likely be here for a long time as 5G is distance/obstacle limited, the former is very hard to overcome due to the wavelength's physical properties.
@blackhawk
I am not disputing how online info says it's required, I am just copying what T-mobile has told me.
T-mobile store rep tells me VoLTE is not really needed, then their online support supervisor tells me the same thing. So it is for sure confusing.
Call a T-mobile support # and ask.
Why would a 3G/4G-LTE phone have an option to turn off VoLTE?

I never paid much attention to this and still have questions but it's back burnered for when I run across it. From what I'm reading the T-mobile reps sound like they don't understand it either.
Even if they don't understand it... the only thing that matters immediately is if it will work. Hopefully that intel is correct!
Really until AT&T implements the change I won't be 100% sure. However pretty sure I'm ok as the devices don't use the 3G band and in hidden user settings VoLTE is toggled on. The only indication other than the 4G that VoLTE is active.
Probably HD too, but no indicator or setting other than very good call quality.
To make matters even more confusing AT&T changed the format and models listed drastically 2 weeks ago from their December whitelist. So small wonder reps might be confused too. Makes you wonder if it was deliberately self serving, an oversight or ongoing system modifications?
So, I have not been paying close enough attention to cellular these days. The cell companies have amassed large sets of licensed bands, probably near 200+ bands between 2G/3G/4G LTE and 5G NR.
Interestingly enough, 5G is not LTE at all. I suspect operators call their crud "5G LTE" to signify they support 5G-NSA or 5G-NR (or both), and, the older 4G LTE.
Some airlines are worried about two cell C bands (n77 and n79) that back up onto aircraft radio altimeter that run 4200-4400Mhz.
VoLTE has a long history, but it seems 5G-NR does not even use VoLTE (because VoLTE is a LTE feature, and 5G is not LTE). Can a 4G/5G phone still use VoLTE? Sure, if the firmware is implemented to use it. Likely will use it if the device connects 4G LTE, but perhaps will not when connected to 5G-NR. It's not clear to me if a device will use both 4G LTE and 5G-NR at the same time, but I suspect not. I mean, you could technically connect a device on 5G-NR for data, and then use VoLTE on 4G LTE for facilitating voice calls.

My understanding on this is that voice was using some 3G or below service. My provider was purely 4G and above - so unless my phone was provisioned by the cell company - no voice calls. I tried & it didn't work. I changed to an older device that they did support via VoLTE and calls worked. I can download an App from the cell company that allows my pixel 2XL to work on their system.
I can only guess T-mobile has 3G and below network infrastructure still. My provider is brand new and never built any 3G stuff and have no intention of rolling out obsolete stuff. VoLTE is annoying in that the provider gets to pick and choose which cellphones they allow (to use a standard protocol)
This may not be 100% - I've been kind of forced into a crash course on this myself over the last few days

Pixel 2's all have ability for VoLTE.
A cell operator should not be blocking any phone from using VoLTE.
When you call your provider what do they tell you when you tell them your Pixel 2 has VoLTE for 4GLTE but your Pixel won't make calls on their network?
I can tell you for sure, the operators play games with their support of hardware.
My iphone XS was connecting to ATT with a "5G" icon from time to time, so why does T-mobile say 5G is a "no"? I moved the XS to T-mobile and the phone won't ever connect to 5G, and the APN settings appear to be blocked.
Tutorials | T-Mobile Support
Update: I find many sites that say the Xr and Xs do not support 5G, so now I scratch my head, my Xs would sometimes show "5G" icon for cell wireless, when it was on ATT network. Apparently AT&T supports Xs and 5G, hence the Xs does have 5G capable radio.

I think they go at least partially by number of a given model in use. My guess is it's not a painless procedure for them to configure their system for a given model.
AT&T first listed their Note 10+ variant but not the unlocked variant, a month later it was added as well. It may be a work in progress... it seems sort of helter skelter, oh my gawd get it done, whatever it takes... kind of deal
You know they are catching Berlin air raid volume flack
Before buying Mi 11 Lite 5G I went into a T-mobile store (not an affiliate). I asked if the Mi 11 Lite 5G will work on T-mobile and the rep told me all phones work on T-mobile as long as they are not locked to another carrier, and, the T-mobile freq bands ("channels") are covered by the phone.
Unless LTE or 5G-NR/5G-NSA is improperly implemented on the device, then I don't see why all phones should not work. They should all work.
Think about hotspot. The carrier can control is the device can use that service, or at least can with some devices, but why bother, who cares how the data on the data plan gets chewed up. Go over the plan and get charged. Thus far I have not seen unlimited hotspot data, T-mobile only allows 40G on their Magenta Max plan.
Good thing is, Mi 11 Lite 5G phone (model M2101K9G) works a-ok on T-Mobile USA. I did have to manually set the APN to the "fast" one, and had to use dial code for VoLTE, 4GLTE and 5G works.
Straight talk now keeps shutting off my service every 3 days, last night again, so 3 times now. Call and back working. But seems like they only care about giving me some crappy free phone and seems like they outsource. The redmagic 6 is not on AT&T list, if any more issues I will switch to T Mobile, T Mobile recognized my phone by imei and said it is fully compatible. I Noticed on my Redmagic 6, sim 1 is only 14 digits but sim 2 is 15, so I moved sim card, might be issue, but doubt it.
@Rotwiler I see you posted about the IMEI digit thing in another post/forum. *#06# should reveal a 15 digit IMEI. If it shows only 14 then the phone is hiding one digit. Put sim card in sim slot that has the 15 digit IMEI.
What does *#*#4636#*#* get you? Do some gooling around for activating VoLTE on RedMagic 6
Phone lists for carriers are mostly for support reasons. If the phone has all the cell bands the operator uses, then it should be good to go. If the phone only has some of the cell bands used, then the phone may work ok in one area, but not good in another, all depends on how the operator runs the bands in different areas. The cell operator does not want the support headache for a phone that only has partial bands, "hey ATT, my phone not working in Timbuck-too", etc.
The RM6 appears to have most of the ATT 4GLTE bands (all the major ones), so it should work a-ok on ATT (US). 5G should also work. It appears the RM6 had a firmware update about 26d ago. Make sure the firmware is updated to latest.

I am using AT&T through Straight Talk. I did move sim card to slot 2 to see if issue was due to sim one showing only 14 digits. Phone is fully updated. Odd thing is I cannot change the APN since this new Volte, there is red check mark and everything is grayed out. I have always been able to modify APN until now. My sim card is really old, used to be full size and over the years cut it down for new phones, is probably 8+ years old, had it since Android phones came out, but has always worked great.

APN settings are grayed out when the phone is locked to carrier. Can you at least see what the APN settings are? If the phone is owned outright by you then tell the Straight Talk folks you want the phone unlocked.
As for old sim card, then just go get a new one from the store for a few $, and then move your number to the new sim card via online.
Phone is Redmagic 6 global version, never was locked.
