[Q] Huawei U8655 Roaming Issue

I have a friend who has this phone. The problem is I inputted the data setting for their service provider and it worked for a while, now though it doesn't work. Enabling or disabling the data settings doesn't work and on checking the Testing Menu the phone has not GPRS service and the Roaming shows Roaming also it shows that it has 3g. The 3g symbol shows up in the notification area yet it wont connect however Wifi works and Calling and Sms work as well.
I would factory reset the phone but my friend doesn't want to do that. Is there anyway to fix this.

[Q] Removing data icon when connected to Wifi?

I know I can hide it with a Rom but I want to hide it on a Stock rooted M8.
I haven't found that option in the xposed apps Gravity Box or Sense 6 Toolbox.
Anybody know how to hide that data icon when you are connected to Wifi?

I just found some kind of glitch
So after tinkering around with an app called 4G switcher, I've found a mode that allows you to make calls (have to disable assisted dialing) texts, and use data without displaying the data connection icon unless you are using it.
What I did was I switched the radio mode from LTE/CDMA+EvDo to LTE,CDMA.
this makes the phone think it's in GSM mode from what I saw in the app Lte discovery, and in the data settings where it says cdma or GSM/umts mode. Will post pics.

Cannot turn on data while in a call (if data was off before call)?

Whenever I attempt to turn on my data while in a call (and data had been off prior to the call) the phone gives me the "not available over VoLTE call"
I have searched for solutions to this which include:
- making sure VOLTE is enabled on my verizon account and on the phone
- Network settings reset
- making sure Advanced calling is enabled...
None of the above work. Anyone have any solutions?

Go into settings, Advanced calling, then advanced calling again and turn the toggle to off. This will turn off hd calling and will allow your mobile data to be used during calls.

Thank you! This does work in that it allows you to switch data "on" while in a call. However, after just testing it, I only get the "1x" data symbol after enabling data and when I try to use data via facebook, chrome, etc. then it gives me the message "data is unavailable while in calls".
will still have to look for another way around it i guess

Apex, one thing I have noticed is that for some reason, LG has decided to disable mobile data during a phone call. In my mind, this is very frustrating as keeping mobile data active during a phone call is one of the main features of even having 4g lte outside of the 4g speeds itself. I dont know why LG has decided this, but then again, they also decided that getting rid of the app drawer would be a good idea too. THat idea has backfired on them to the point that they had to release an update just to incorporate it back in.

additional settings and connection problems

WiFi Calling - Setting Priority

My provider (O2 Germany) allows WiFi Calling (voice over WiFi) and I have activated it on my P20.
Is there an option to "Prefer WiFi connections when available?"
At home, the mobile networks only work near the windows. Within the flat, mobile calls often get lost so I am glad to finally have a phone that can use the WiFi network.
By default, the phone prefers the mobile network and only switches to WiFi when the mobile network is lost.
Can I set the phone to prefer WiFi and use that when available and only switch to the mobile network when WiFi is out of range?
I have read somewhere that Samsung phones provide such an option, but cannot find it on the Huawei P20 phone.
The only workaround I have found, is to switch on airplane mode and then manually switch on WiFi. That works and I can still make and receive calls that way.
I looked through Developers Options, but could not find any such setting.
Anyone?

I am searching also for that setting. My mobile network signal is to low to live and to high to die......
Would appreciate if that annoying P20 would give me the ability to decide how it should behave....
Thanks on any help!

The only way I found to force WiFi calling is to switch to airplane mode and then switch WiFi on again. Then the phone will remain constantly in WiFi calling mode. You just need to remember to switch off airplane mode when you leave the house.

I just got angry after my post an treated Google.
For the Moment i found a solution, hope that will persist...
If i go to the dual SIM Config Menu there is an option to activate LTE on both SIM Cards. It is, in my German Branded P20, the last option.
When i disable that option as mentioned on the Internet the phone takes 5s and switches automatically and, for the moment, permanent to WiFi Calling...
Crazy. Hope that solves the issue foe me permanent and maybe helps for you also?
I think there is no bigger disadvantage on deactivating the function when WiFi Calling is now working properly

I just received a new firmware update to EML-L29 8.1.0.165(C432) which adds VoLTE and VoWiFi features - I thought we already had those features, but maybe they have improved them. I have not seen any new settings and even with your suggested settings, I am not getting permanent VoWiFi.

Hi Peter,
after some days testing i have to report, that was happy to early...
Just not reliable, also with my "hack", which also caused me some other troubles in regions were i have the issue that the carrier has just build LTE transmitters and no other frequencies.
Also, WiFi Calling works not really reliable on Huawei P20. Annoying!
So we have to hope that Huawei will bring a fix for that....
