Hello XDA community,
I have a Mi Mix 3 Palace Edition phone and I am using AT&T for my carrier. The phone came with a Chinese ROM but I flashed it with a Global one. I have been trying to get 4G + LTE to work on the phone but so for all I am able to get is 3G. I have contacted ATT and was told that my account was not setup for it. So ATT's advanced technical support made sure the IME/my account on the phone was LTE enabled. I am still stuck on 3G. I have selected the correct APN for it but I do not connect.
What am I missing?
Preferred network Type?
preferred network LTE.

Did you checked if your apn is correct?
Try selecting 4G network manually. I faced issue like that initially with ATT MVNO. After seleting 4G network manually I am geetting 4G+
In the Settings, go to About Phone, and tap the storage until it brings you to the SIM and WiFi screen. Tap on the Phone Information for the SIM you are using and set that Network Type to UMTS/LTE.
AT&T blocks any device you did not purchase directly through them from using VoLTE and WiFi Calling. 4G is also LTE, so if you see the 4G icon, that is also LTE and 4G+ is also LTE-A.

Hi all,
i have an unlocked at&t one x. i'm using it in india on vodafone network. i wanted to know if 3g will work on this phone? i see the E symbol on the notification bar. does that mean that it will work only on edge? the frequency bands seem to be compatible. is there anyone who is already using it on the same network and can help me out with this? thanks.

Did 3G ever worked for you ? How did you unlock you AT&T one x, sung unlock code ?
If you go to your dialer and type in *#*#4636#*#* , you will go into testing mode - where you can check your network settings. Verify that your network is not set to something like "LTE Only" (which is not available in India).
Preferably set it to "WCDMA Preferred" or "WCDMA Only" (You can also play around with HSPA ).
See if that works.

this should be in Q&A section.
Are you having any 3G plan from vodafone? - If you are on 3g plan you should get 3g automatically.
-Try changing network modes if you have a 3g plan but still get edge only
Having the same problem..
I have an AT&T Unlocked HTC ONE XL (Eviita)
Its Bands seem to be compatible with 3G Bands in India.
I have tried everything (*#*#4636#*#*) and tried all banks.. on "WCDMA PREFERRED" it still shows "E" and my sim comes 3G data plan is active.
I have Unlocked Bootloader, S-Off, Rooted, Installed Cynganemod 10.2 (Android 4.3) with G-apps and its all working fine, but still no 3G.
Any help on this from anyone.
Theres only 1 thing i can now think of... when u go into (*#*#4636#*#*) mode and click on Phone Information and scroll down, u can see one tab which cannot be clicked and it dimmed out, it says... "OEM-specific Info/Settings", but you cant click it.
Is this a Data Locked phone?

When buying any phone from a source other than your carrier, you need to do the research on band compatibility BEFORE you buy the phone. As this is set in hardware, and is can't be modified. The fact you say "seems to be compatible" implies that you aren't sure.
Also, you haven't mentioned what carrier you are using. The OP says Vodaphone, and I can't find any info on what MHz band Vodaphone uses for 3G. You need to know what band your carrier is using for 3G. Your carrier needs to be using one of the bands 850, 1900, or 2100 MHz for 3G (HSPA). Otherwise you will not get 3G on this device.

That doesn't mean anything, did you make that up? Either the phone is SIM unlocked or not. There is no "lock" on the device that would make you get EDGE but not 3G. Getting EDGE but no 3G typically means that the device is not compatible with your carrier's 3G network.

I've reported the thread to mods for moving.
Thread moved to Q&A forum.
is your phone on 'gsm only' mode ? I've used the same phone in India but it wasn't a AT&T one though.
Hi,
I can't receive 4G LTE on my phone.. I can only receive H..

Try checking that your Access Point Names are configured properly in your mobile network settings in your settings.
you might have to have net10 provision LTE On your SIM.
Update: I called the customer service and they told me that my area zip code: 54601 is not covered.. but when I go to AT&T website I see the city is fully covered.. do have to call AT&T to activate it for me?

dial *#*#4636#*#*
go to "phone information"
scroll down and check your preferred network type
if its on WCDMA prefered change it to LTE/GSM and turn on LTE ram dump

What does LTE ram dump do?
Weird, I decided to do some Googling about the matter and I can't find anyone who knows what it does. I suspect that it dumps the contents of the RAM that LTE is using atm. I would leave that off.
You just can't set an apn and get LTE, your account has to specifically be provisioned for it to allow it. With out the provision you're stuck on HSPA

Honestly I don't know either. I tried looking for a post where someone vaguely explains what it does. Couldn't find it. It was a step for enabling LTE on the Nexus 4. Probably best to leave it off like you said.
I contacted the customer support and told me that 4G LTE is enabled on my account .. On AT&T website it says that my city is covered but NET10 representative said my area is not covered
Do you have any other ideas?

The 4G signal that the networks worldwide use are not the same, GSM 4G is not the same as CDMA 4G, also, some 4G devices in the past were not true 4G, they used Wimax which is not actual 4G. My point is, the 4G your network uses is probably a different signal type or its bands do not match the bands the device supports. Research the exact signal type and frequency bands that Verizon supports, then research what signal type and bands that your network supports.
Many times I've seen 4G CDMA devices used on other networks and 4G could never be made to work, they were stuck with 3G because the device did not support the 4G type their network uses.
Most devices on other networks but still have 4G can count themselves lucky.
Thanks for your reply,
I flashed this rom (CM13) ; http://forum.xda-developers.com/gal...m-cyanogenmod-13-0-nightlies-verizon-t3269675
my provider is "Djezzy" , and i think its 4g LTE.

You "think", no, don't assume anything, even if your provider uses 4G LTE, if the bands/frequencies of your network are not supported by the device's hardware then it isn't going to work. As I said the first time, you need to do the research to see what bands and frequencies Verizon uses and then do the research to see what bands/frequencies your service provider uses. I mean find the actual values of Verizon's bands/frequencies and the actual values of your networks bands/frequencies, you need to compare them to see if the use the same bands/frequencies, not just whether its 4G or LTE or not. Do you understand what I'm saying?
Also, their may be radio/modem incompatibilities, the radio modem is part of the stock firmware that remains on the device, ROMs are just the system partition and not the whole operating system, software that is under the ROM is still the software the device came with or had before you flashed a custom ROM.

verify that you are in a location that gets a good signal and that it says you get 4g lte data. then goto connection settings>mobile networks and tap on network mode and choose the option in the screenshot. if it doesnt change do a factory reset. if that fails either get the stock rom from sammobile and flash it with odin or call samsung for a replacement. also verify that theres no upgrades or problems in your area by calling customer care and that your house doesnt limit your signal. my house sometimes limits mine due to it being metal all around. in that case putting your phone in a window fixes it. if you want to avoid that contact tmobile to get a signal booster for your house. update: in the *#2263# menu make sure to choose reset on both LTE and WCDMA in disable band.

This phone doesn't have certain bands asia uses. you may need to buy the sm-j327u (samsungs unlocked version of this phone that can work on cdma and gsm carriers.) the sm-j327t1 was designed for the united states.
to fix this problem install (Force Lte Only).apk from play store go to phone information>Network mode>Select WCDMA ONLY!
it will fix the problem as well as you'll have all option enable i the network mode!

Need some help here, still stuck on 2G. Though I don't have a T-mobile sim card, the device is said to be unlocked (by @ashyx ), so I want to use my sim card. So what am I supposed to do (I've tried everything listed here so far, no luck)?

Have you checked which bands your network supports against the bands your device supports?
You may have to open the network settings and modify the bands if possible.
Also which firmware are you running, you may need to flash the modem from the orange firmware?

Hello, my problem is the phone prefers 3g over 4g even if there is excellent 4g coverage. Looks like the phone gets stuck on 3g after leaving 4g area and never tries to change network unless I put it in airplane mode for a sec. I have 4g set as preferred in network settings but this doesn't work at all, only solution is to set lte only in hidden menu, but that obviously causes other issues. Is there a fix?

Same here (Play). I think it's the operator's fault.
