Unable to register in 3G (HSPA+) - Oppo Find 7 and 7a

I've purchased Oppo Find 7a (x9000) from china market. After bringing the device to my country Bangladesh, I've been trying to use 3G service but could not be able to register to 3G network. However, 2G (voice and data both) is working fine.
Test cases -
1. My 3G SIM works well in other 3G devices
2. Other 3G SIM doesn't work in this device.
3. Set network mode as "WCDMA Only" and "WCDMA Preferred". None worked
4. Tried to register to 3G network forcefully (setting-->Geenral--->Mobile Networks---->Network Operators). It shows error message " Can't connect to this network, please try later"

Sprint LG G3 not showing any cell sites in the Llama app

When I open the llama app, the recent tab does not show any cell sites. It only shows no signal/unknown or :-1:-1:-1 which I think is just the default for when setting up a new phone. I even clicked on the areas tab for home or work and start learning area for 4 hours or so. The only time when I can actually catch cell sites is when I turn off lte and only use 3g data. I'm not sure why the LTE data mode would not be able to capture any cell sites. My phone is rooted with stump root and I have made a few tweaks with G3 Tweaksbox. Other than that not sure why the sites aren't captured.
Can someone else test this on their Sprint LG G3?
Thank you
I can't get Llama to learn any of my locations.

Am I on LTE?

I just got my wife an unlocked G7, model LMG710ULM for use on AT&T. I am trying to figure out if I am connecting to LTE. The Icon says 4G but using an app called Network Cell Info Lite, it appears I am indeed on LTE. LTE is definitely available as my Z2 Force shows the icon.

So there is no LTE icon on this phone?
If u have VoLTE it shows a icon
If u Dont its just the 4g icon. 4g =lte
That's great news, i was worried i would have to return it. Is there a menu option to turn VoLTE on?

mobile network gone after updating to MIUI 10.4.4.0(PGGINXM) Today

I updated to MIUI 10.4.4.0(PGGINXM) after the reboot (update) mobile network is gone (I'm airtel user). i tried to restart but didn't work. i also tried to reinsert the sim card but didn't work.
Try add it a OMV in the APN settings.
Default APN config

Its generally a problem with the vpn
check your vpn configuration in network settings
if you dont konw the values, ask your operator they should have no problem to give them to you
also check if the authentifiation is set to default in the APN type field
Try it like in the image, I dont recomend changing MCC & MNC values

Network data issue

Hi all, typically my 1st post is a question.
My wife has had a G7 for the last two years and really never took it out of the house, therefore she was always connected to the home Wifi. I have just decided to sell it and there does not seem to be any data connection. It the Network area of the settings, "Mobile network state" it says "disconnected".
Now, I can't remember if it has ever used mobile data.
Wifi and actual voice calls & SMS all works.
Details are:
Fully unlocked ex T-Mobile, working in the UK
Software = Andriod 10, G710TM30b
Last security patch 1st September, 2020.
Model = LM-G710TM
Any suggestion would be of great help
Thanks in advance
Stu
