4G network not available in Switzerland - Xiaomi Mi A1 Questions & Answers

Hello everyone,
I just bought a mi A1 but unfortunately the 4G network didn't appear in the list of available networks anymore. I checked the settings and 4G is the preferred network type. Also, I have LTE/UMTS (auto) as preferred network type in phone info. I tried several options with no luck.
Any help would be very appreciated, thanks!

Did you put the code on the telephone dialer? If so,
try one of the solutions on this page: https://www.google.com/amp/s/www.technobezz.com/fix-connection-problem-invalid-mmi-code/amp/

I put LTE/CDMA/UMTS (auto)(PRL)
LTE it's the same as 4G

According to https://willmyphonework.net/ should 4G/LTE work on Your network.

Telcel + HTC Aria = No 3G?

Hi guys,
I just bought this phone, unlocked it and inserted my sim everything was fine until... I noticed the "edge" icon.
It wont connect to the Telcel 3G network, I know that this phone is for AT&T network but Telcel uses the same frequencies (UMTS 850/1900), I tried "forcing" it to WCDMA only but it wont find any Telcel network.
What can I do? Does anyone have experience with this kind of problems?

Aria comes with APNS setup for AT&T data only. It's a simple fix - you can manually enter the info under wireless settings to add access point data for your carrier or you can just root and flash CM6, with has a huge - enormous default APNS database.
Here's a link to how the same issue was solved on the Nexus One.

Thank you! I'll try this right now!
-------EDIT-----------
Ok I entered the APN info, restarted the phone and Edge Icon is still there, with the "settings" on *#*#4636#*#* I changed to "WCDMA only" and the phone cant find a telcel network, only movistar, What is the problem? Maybe there isnt a Telcel 3g network near my phone? I used to have an iPhone 3G and I never had a problem with 3G Any thoughts?

Note 3 LTE no option for 4G network connection

Hello people,
I have recently acquired a Note 3 LTE (Snapdragon 800) model of the phone which is 4G compatible but for some reason, I get no option to select a 4G network. The only options I have to chose from is 3G/2G (auto connect) and 3G only. I have attached a screenshot below showing what I mean. On other Note 3 LTE phones, I've seen a different set of options such as LTE/WCDMA/GSM etc...
Why is it so? I am running the latest version of android according to Samsung update which is version 4.3. So is this a software issue or what? My service provider says that samsung should release a software update to solve this issue but I don't understand why this is the case. If anyone can clarify this issue for me I would be very glad.
Thanks!

What region are you in?
What firmware version are you on?
Has your LTE been activated by your provider yet?

I am in Beirut, Lebanon.
I also have a Galaxy S4 with the latest updates and I get a 4G connection in certain areas. So yes, 4G had already been activated by my provider.
I've attached another screenshot because I am not sure what you mean by firmware version.
Can you compare the S4 and Note 3 "apn settings" to see if they are the same? You might have to manually input your carrier's apn settings into the note.

The apn settings are the same since they have been both configured automatically when the service provider sent the settings to be saved.
What else could it be?

Try flashing one of the other LTE N9005 roms and see if you get the listings under settings appear( backup first). I know some roms take this option out like at&t here in the states.
---------- Post added at 10:01 AM ---------- Previous post was at 09:55 AM ----------
Better yet try this:
open your dialer and type *#2263# and see if you get the lte option.

Alright so good news. I received a message telling me that there is a new firmware update available, so I downloaded and installed it. Now I get a 4G option even though I never once got a 4G signal during the day. I guess waiting is my only option now. What do you think?

Hi guys.
I am facing a somewhat similar issue. What makes it different is that I had the LTE option when I bought the Note 3, although there was no 4G service in the country at that time. However, I think it was after an update that I no longer have the LTE option available to in my network settings. Right now, in my home country, LTE hasnt yet been introduced. But like I said, there was no LTE in my previous country of residence either yet I had the LTE option.
By the way, the code *#2263# does nothing at all on my set.
Appreciate any feedback and resolutions.
Thanks

If your phone is rooted (seems like it isn't) then you can manually edit a config file to enable LTE. If not, you'll be waiting for another OTA update I think.

sadi2e you have to go Touch or Alfa to replace your SIM with a 4g compatible one, btw ignore the costumer support telling you that you won't receive any signal if you get out of 4g zones,they are total idiots
I replaced mine and now getting 13 14 mb/s speeds

Im from there too originally. Did you change your modem at some point? It could be that your current modem is not LTE capable. Or let me ask you this: Did you install a stock rom from a different country other then the one that your device is intended to? bas bi beirut fi LTE aw wen maken?

Hello , I have a USIM, and note3 4G ( bought from KSA and tried on 4G in Dubai and KSA) . I did not get any updates on wifi nor through kies .
Did you change you upload a new platform ( kitkat) before you got the update ? or did you just wake up and found an update ?
PS : I live in Beirut Lebanon too .
Thanks
Me too with the same problem
I bought my phone from Dubai.. i saw the LTE option when i used my phone there.. but then i flashed Poland's latest firmware and rooted my device.. now i am in South Asia , and my phone doesn't show any LTE option..! :silly: weird..
I'll say it again: Each CSC has a different list of 4G activated providers that are not directly related to the region they are in.
Which means that a device can have 4G activated for 50 providers, just not the one your SIM belongs to. As such, if you insert the SIM, the 4G toggle is disabled.
Each provider has to individually pass on the fact that they have 4G to Samsung. Even then it's not activated for each CSC.
As such, my DBT Note 3 had 4G on T-Mobile NL months before the TL and PHN ROMs had it.
Also, South Asia uses a different frequency your EU firmware can't detect.

Engineering mode

Does anyone know how to access this so that I can check which LTE band I'm connected to etc?
On my LG it was simple - I just entered some numbers and symbols into the dialer.

Thanks, but that is not reliable at all. The only reliable way to tell is in engineering mode. Too many errors with those apps.
This worked on my old Sony and it seems to work here as well:
Go to your phone dialer and enter this:
*#*#4636*#*#

You need root to know the actual LTE band.

I"ve noticed the end is reverse of the beginning in the past, so I tried that and it worked.
So dial *#*#4636#*#*
But that doesn't tell me the LTE band. Maybe the Axon 7 doesn't have more information.

TD-LTE:Band 38/40/41 ,
FDD-LTE: Band 1/2/3/4/5/7/8/19/20/28AB,
I've looked around, and I don't think there is an engineering or service menu available.
Network Signal Guru: https://play.google.com/store/apps/details?id=com.qtrun.QuickTest&hl=en
While it's not engineering mode, it does have deeper radio access than tools like LTE Discovery and Signalcheck. It has the ability to turn on and off (supported) bands, allows band locking, etc.

No 4G/LTE after August security update.

As the title says. I'm using the Global version of the Mi A1 and after the update I don't get any 4G, even at home where I had full 4G reception before. Anyone else have any problems like these?
Nope, it's okay for me. Maybe you can change your prefered network typing in the dial *#*#4636#*#*

Tried that, doesn't stick and changes nothing. Setting a new APN likewise doesn't do anything.
Did you find any solution?
Yeah, flashed the most recent modem from the modem thread again.
