I played around with the engineering mode on my f21 pro 3/32 trying to get volte to work, instead what i got is a device that won't connect anymore to 4G. network cell info tells me that it is connected to 4g reception but the device won't register on the network, so basically the bars remain empty and shows on the app that it is receiving 4G signal but not registering. i cannot for the life of me figure out how to fix it. any ideas??

HI Guys. I think this is what's known as a 'senior moment'! I'm still getting used to the subtle differences between my new Mate 9 and my previous Android phones and I have a question about the icons at the top of the screen...
I'm sure that with previous phone,s if WiFi was on it didn't show the data connection via the phone e.g. H+/3g/4g - in other words, it was one OR the other.
I just noticed that on my Mate 9 (L29) BOTH are showing - see attached. Is that unusual? ... or am I going nuts?
Thanks
Huawei does it different, you're not going nuts!
I actually even have the internet speed up there too?...

I think it's how Huawei manages Wi-Fi +
They're a lot more efficient at switching between mobile data and wifi than anyone else....
Thanks for the info! :good:
Trouble is even if I turn off mobile data and wifi 4g LTE icon still persists. Is that also a Huawei thing?

Turning WiFi off has nothing with 4G.
However ('Huawei thing'), even without Mobile data, it still connects to 4g (but it shall switch to 3g for calls - you can check).
You can disable 4g in Settings / Wireless & network / Mobile network / Preferred network mode, select 3g/2g auto

With mobile data off, it still shows 4G icon in status bar and doesn't connect to anything. My point being it shouldn't show the 4G icon in status bar when mobile data is toggled off.
I believe this has to do with region C185 firmware. As the western Europe versions don't seem to exhibit this behavior.

Yes, it still shows 4g icon because IT IS connected to 4g - please read my previous post/answer
And you can install Net Monster or LTE Discovery and you will see that it is indeed connected to 4g (and to which 4g band, etc) while idle (although you switched Mobile Data off). It only switches back to 3g during the call.
It's not that icon is wrong, it is Huawei behavior.
And it doesn't matter, nothing is wrong in that - it just means that although you switched Mobile Data off, it still attaches to 4g when you are not in call (although you are not using 4g data)
Install Net Monster, LTE Discovery, Net Monitor or Network Cell Info Lite to see details about the band, cell, etc, it us really attached to

It just so happens I have the pro version Network signal info. Yep you're effin right. Its says it's connected. Albeit won't let me upload nor download data. Why does Huawei do this? Other devices normally when disconnected from mobile data show just bars and not 4g LTE icon.
Hey I recently purchased Pixel XL from store.google.com and had it shipped to California and took it to Shanghai, China. After inserting the china telecom sim card, i found that I can only make/receive phone calls but cannot connect to LTE network.
It is clear that the hardware does support the china telecome LTE network. I even find a small tutorial of switching to a mode where I can use LTE network but cannot make phone calls.
Dial *#*#4636#*#*
on the upper right cornor , choose United States
in the middle of the screen choose CDMA AUTO (PRL)
turn on Airplane mode and then off
Then I can find LTE signals.
But the phone cannot make phone calls under this mode.
I'm not sure if I can switch it back to make phone calls mode. And is it possible to solve this problem and make it able to receive phone calls and have LTE network at the same time? Tremendous thanks!! If I can provide any information, please guide me to find the information and I will happily provide!.
Have you tried LATE/CDMA/UMTS auto (PRL) mode?
I could imagine that this let's you use both, China mobile LATE (which obviously needs the CDMA mode) as well as UMTS as fallback for calls.

Currently a file(carrier_policy.xml in the EFS partition of Pixel 2 series and probably Pixel 2016s) lacks proper configuration for China Telecom with its LTE network using SRLTE (which is a common practise of establishing the CDMA and LTE network at the same time).
Thus the team can and should fix it by:
Adding the following 2 strings(in red) to the carrier_policy.xml in the EFS partition as follows:
......
<!-- List of the MCCs in which SRLTE is allowed -->
<mcc_list name="sxlte_mccs"> 455 460 </mcc_list>
<!-- These are the serving system PLMNs for which SRLTE will be allowed
-->
<!-- NOTE: Proper functioning of the SRLTE policy requires that there
be an PLMN list named "sxlte_plmns". Do NOT rename this list.
-->
<plmn_list name = "sxlte_plmns">
455-02 455-07 460-03 460-11
</plmn_list>
......

Hello everyone, I am a Nokia 8 user like all of you and my device on latest Pie Build (v5.140). Somehow i faced LTE Signal Dropping problem this morning. My problem seemed bug-dependent and finally i solved it. Now, i'm going to explain you how i repaired my dropped LTE signal.
(Warning: This guide was prepared for bug/software-dependent issue, not operator-dependent.)
First of all, turn off all network connections (WiFi, Cellular Network and Bluetooth).
Step 1-)Reboot your phone to safe mode.
Step 2-)Reset your network configurations; for this, go to Settings>>System>>Advanced>>Reset options>>Reset WiFi,Mobile and Bluetooth. Cellular network will be turned on, turn it off again.
Step 3-)Go to Dial and write *#*#4636#*#* code. You will see Testing menu.
Step 4-)On this menu, touch Phone Information tab.
Step 5-)On the opened menu, we need to apply some changes over Preferred Network Type and Mobile Radio Power. Switch Preferred Network Type to LTE/CDMA/UMTS auto (PRL). Wait for device to apply configuration. 10 seconds later, turn off Mobile Radio Power and wait for your device to turn off the radio communication. 10 seconds later, turn on Mobile Radio Power again.
Step 6-)Apply normal reboot.
That is all, i repaired my dropped LTE problem by applying these steps and i hope it will help you all.
Hi,
Iam from Germany and my provider is Vodafone.
I have the same problem with lte dropping.
Your instructions didnt help for me.
The only thing what I can do is enable and disable flight mode. In some areas lte is dropping more often and in some places less.
Is there possibility to get some debug information?
Maybe I have a hardware defect and need to repair my device?
Mine too. South Africa. I normally have lightning LTE speeds and all of a sudden ....i have to tab airplane mode on / off probably 3 or 4 times in order to regain steady LTE strength...
I have the one plus 8 uw from Verizon. I cannot for the life of me get this device to connect to a 5g network nor my 5ghtz router. Is there something I'm missing. I have changed my plan, reset network settings and even tried safe mode on the device. I'm in a 5g area as another device can connect sitting next to me.
Try going into settings, Mobile hotspot, find wifi 6 standard hotspot an try either enabling or disabling it.
Hi,
I am from New Delhi, India. Few days back I have got a new P11 Pro Android Tablet from China. It is 5G compatiable device with Dual SIM capability. When I started using it, the tablet accessed Mobile Network only for few minutes and disappeared. It has only 5G (recommended) option under Preferred Network Type menu. I have made all possible settings but network accessiblity is still remain a distant dream. Very rarely it is getting connected to mobile network, that time I can access only mobile data but to make a call I need to wait till the VoLTE indication to appear on the screen. But that will also vanised away in few minutes.
It would be a great help for me if anyone help me out to resolve this issue ?
