I will mention that I did not test this out on the phone before installing /e/. I got it off of ebay, after seeing its IMEI is supported for WiFi calling with mint mobile, and immediately installed /e/ when I received it.
I found a spot in the house that has no cell coverage, so that I could test this feature. I’ve also ensured I have the feature enabled with my carrier. The same location in the house has great WiFi reception.
I’ve attempted to make a call, but it errors with: “Mobile network is not available. Connect to a wireless network to make a call.”
I am definitely connected to WiFi. I verified I could still browse the internet.
Does anyone have more information on getting this to work?
You bought your (used) Nexus 5X on ebay and didn’t check it for full functionality. This means that you lack the certainty that the phone is in good working order in terms of hardware.
Did you make a system back of StockROm Android after installing TWRP Recovery at the latest?
What StockROM Android firmware was installed on the Nexus 5X (6.0.0, 6.0.1, 7.0.0, 7.1.1, 7.1.2, 8.0.0 or 8.1.0) before switching to Google Nexus 5X - /e/ for “bullhead” * dev (oreo)?
It looks like your mobile SIM-card isn’t recognized, right? I also know this problem from some Samsung devices. As a first solution I recommend to reset your device within the TWRP-Recovery menu to factory settings → “Wipe Data/Factory Reset”.
Sorry, I meant to say open box, never actually used before. Never used with any carrier. But obviously not mint because they had to open the box to take a picture.
That’s an important statement! That is what I was going for with my question.
With WiFi calling (“Voice-over-WLAN”) or VoLTE numerous custum ROMs based on LienageOS have problems, even if the provider supports these extended functions and a suitable tariff.
I would start all over again and test if the Nexus 5X with the current StockROM 8.1.0 can perform all desired functions flawlessly. Based on this it can be checked what custom ROMs are capable of.
Hi @archie, I’ve found instructions at develops.google.com/android/images to restore a full OTA image for my device. Is it ok, in your scenario you described, if I sideload the OTA image, or do I need to flash the factory image?
I would first install the last available facorty image “bullhead" for Nexus 5X” 8.0.0 Oero to ensure compatibility with /e/ for bullhead dev (oreo). You may also install version 8.1.0 Oero if 8.0.0 does not provide the desired result.
With these Facorty-Images all functions (WiFi calling, VoLTE) can be checked for proper function.
@novacane, many ways lead to Rome and the important thing is, to start walking and not resigned…
You’re free to do whatever you think is right. I make here only suggestions for solutions.
