Hello,
From my Xiaomi Mi A2, I have access to data (internet) only in 4G, as soon as the phone is in HSDPA or other it does not offer me data access.
Why?
Do you have this problem too?
Thank you,
Regards,
SOLVED.
It's my APN are wrong, I don't now why.
I had exactly the same problem with Sosh (Orange) in France.
The APN set by Xiaomi for Orange is set for networks 3G+,UMTS,LTE.
But Orange use HSDPA, not 3G+....
I had to make a new APN, where I did not select any network type, so it covers all types.
Interesting fact is that APN in AOSP source code is good, it seems that Xiaomi customized the APNs, but badly
Hi,
I am using a Mi 9 for the few days now and at least twice a day my mobile data connection is down, in order to restore the mobile data I have to disable mobile data and re-enable or switch on and off flight mode.
I have the latest global MIUI 10.2.13, there are no data restrictions on the phone, data roaming is on, mobile data when device is locked is set to never, same sim card was used on Huawei phone whitout any similar issues. Beside the signal bar there is showed full 4g reception, but mobile data is not working.
Does anyone have a solution for this issue?

Have been having data loss on 4G since.... And I own the device from April....! I don't know if it is related to the device of just the network provider...
But... Enabling Airplane Mode and disable it after does the trick....

This worked out for me and the issue dissapered, I am not loosing mobile data anymore.
Go to the APN settings (Settings -> SIM card Settings). Choose your sim card with the mobile data, enter APN settings, scrool donw to the very bottom and in a field called MVNO type select IMSI.

Enabled it....will report back if no network loss anymore...
Just enabled it now. I'll report too in a few days testing..
Can you explain us what's is that configuration?
The Mobile Virtual Network Operator will use data from the sim-card, International Mobile Subscriber Identity, to configure THE phone.

Mobile virtual network operator type / value
Together, the Mobile virtual network operator type and Mobile virtual network operator value fields allow an APN configuration to be restricted for use only when using particular MVNOs or subscriber accounts.
Without this setting, custom defined APN configurations are selected according to MCC and MNC only, which specifies the mobile network the phone subscribes to but not the particular retailer or reseller, or account on a network.
This setting is useful if you want to use different sets of custom defined APN configurations with different MVNOs (resellers) which access the same network, or even with separate subscriber accounts within the same network or reseller. That is, if you switch your SIM card to one of a different subscriber or reseller but the same mobile network, you can set your device to use a different APN configuration.
To use this feature, you need to set both a type and a value. The matching algorithm depends on the type selected.
Types
None
This is the usual setting, and means that this APN configuration is not restricted to use on a particular MVNO or subscriber account.
When the type is set to None, the value field is not used.
SPN
Indicates that the value to match is a SPN value (Service Provider Name).
IMSI
Indicates that the value to match is an IMSI value (International Mobile Subscriber Identity). This value is unique to every subscriber account on any network world-wide.
GID
Indicates that the value to match is a Group Identifier Level 1.
What to do if all the APN settings are greyed out and uneditable?

I would take a note of al the settings then remove/reset them and create manualy new one with the exact settings and it myght let you change the MVNO type, or google them for your network provider.

Yes I've tried this now and I was able to set the MVNO type by creating a new APN and copying all the other details over.
And it didn't work. I've been on the London Underground this morning and obviously lost signal, and every time I come above ground, no data passing until I toggle it off and back on again.
So that's not a fix for me.
Mi 9 shortly going for sale....
The same for me.. I was on São Paulo's subway this mourning and when I went out there was no data until turn on/off airplane mode.. disgusting...

Could you perhaps provide a list of your APN settings and the name of your operator?
I have the same problem .. I have received a new phone from my seller. My first mi 9 was on version V10.2.26.0. PFAEUXM. My new phone runs on V10.2.15.0. Without 4G problems. So its not possible to update my phone.
Next week I will unlock the bootloader and flash the pixel rom. Would the problem be solved then?
Hello, I'm with software global 10.2.30.0 PFAEUXM and still happening data capability lost. Does anyone still with this problem? Thinking on return to samsung, it's very bad bug...
I complained to Amazon where I bought it, they gave me a full refund. Apparently not the first Mi 9 to be returned with this fault.
Now I wait four days until my Pixel 4 XL arrives. Expensive, bit hopefully supported!
I can make a call and text message but my mi 11 (CN version) cannot connect to the AT&T network. How can I fix this? Thanks for your reply.
I manually change the APN settings to reflect AT&T network and it works.
Hi folks...
I set up my new Zenfone 8 to use as a WiFi hotspot. It doesn't work at all (I tried connecting with my computer, and with another phone, and I get no internet connectivity).
However, if I use my work's Samsung S20 or my old Sony XPeria XZ2 Compact, it works fine.
My work's on Verizon, my personal devices on AT&T.
The only things I can think are either:
1. There's a problem with the Zenfone 8 for use as a hotspot
2. AT&T is blocking that phone for use as a hotspot (tho' I don't know why they'd allow it on my XZ2 Compact - both are unlocked phones I didn't buy from AT&T)
Any ideas what might be going on here?

I dont know if this is what happened to you, but I have to changed my hotspot password to WPA2 instead of using WPA3

Ok, just tried it. Also tried various other changes to WiFi Tethering settings.
Unfortunately, nothing ended up working.
I'll do my experiment using my old phone, and then, at worst, pay AT&T extra for the priviledge. :-(

Turn "Allowed devices only" off, if it's on - I needed net on my other phone because of a LAN network outage, and I just couldn't properly connect when this option was on.

Hi, Try following actions:
1. On all of your devices forget your hotspot network first
2. Setup hotspot without password first
3. Try to connect and test the connection
4. Once connection success, disconnect then change the security to WPA 2
5. Forget hotspot network again
6. Reconnect with WPA2 password
On my case somehow all of my devices need to forgot hotspot and re-setup hotspot. I don't know why but before forget and re-setup all my devices could connect but unable to browse internet
I use hotspot two days ago , i don't have time when i use it to find how connect with security so i disable security and it work fine
@hadi_rena @mick711 Unfortunately, none of these worked; I tried connecting to the Zenfone 8 from multiple devices, and though they connected to the hotspot, there was no internet connectivity. I'm presuming AT&T is blocking it and want me to give them more money to allow it.
Hey, Tim and perhaps others having this issue. I wanted to share my experience with being able to connect to the wifi hotspot on my Zenfone 8 but not having internet connectivity. In my case, my carrier is Consumer Cellular on the AT&T network.
Upon receiving my new Zenfone, I lost the wifi hotspot capability. I have heard that Consumer Cellular, and other carriers, require you to request that the wifi hotspot feature be enabled. For me, this wasn't the issue, as the feature worked fine when I switched my sim card back to my prior phone, a Sony Xperia XZ1. With the sim card in the Sony, I dug into the APN settings and discovered a few differences when compared to the default Consumer Cellular APN settings on the Zenfone. I first attempted to add a new APN to try out different settings on the Zenfone, but was puzzled why after creating a new APN, editing its settings, and tapping save, the APN was not saved to the APN list. I'm guessing that this is a Consumer Cellular block. Then, I decided to edit an existing APN, I believe it was called Tracfone. The settings which seem to enable the wifi hotspot function are the MVNO type and MVNO values. Another strange quirk is that when you edit these values and save the APN, all the other saved APNs disappear from the list. If you then change the MVNO values back and save the custom APN, the other APNs reappear, perhaps another Consumer Cellular effect? At first, I was concerned that changing these settings might interfere with or disable some network-related functionality, requiring a quick APN edit every time I wanted to use the wifi hotspot option, but I have not noticed any issues. I realize that these MVNO settings are related to carriers like Consumer Cellular that utilize the networks of other major carriers: AT&T, T-Mobile, Verizon, etc., so this fix might not work for everyone. I thought I would share it anyway. I have attached screenshots of my APN settings for reference.

Thanks for this! How did you know which values to use for MVNO Type and MVNO Value? I have AT&T, and those values are both unset for the AT&T access point.

I just tried the two settings that worked in my older Xperia XZ1. I've attached photos of the settings from that phone. Both configurations allow for wifi hotspot on my Zenfone 8, but I have only used the GID for any length of time. It seems that when you choose the MVNO type, it autofills the MVNO value, at least it does for me. I don't fully understand what these settings mean other than that they relate somehow to resellers. I just know that changing them allowed the wifi hotspot to work again for me. Someone else here would probably have a better explanation for it.
Edit: I found the following link that explains some of the MVNO settings.

Has anyone figured out how to force VoLTE on Origin OS Ocean when the phone isn't on the 'supported' list of your carrier? If it is supported then as soon as you pop in their SIM card the option to enable VoLTE appears, but otherwise it just isn't there. With 3g networks shutting down in North America this creates a real problem, because even though I have 5g enabled, and usually pick up a 4g or 5g signal where I live, without VoLTE enabled all calls connect on 3g.
It's a real bummer. But whatever is under the settings, VoLTE is not actually activated. And Vivo is to blame. That's obvious from the service menu.

The VoLTE issue lies with Vivo, not with your carrier. When you put a carrier SIM into your phone it contains unique information that tells the phone who your carrier is and the phone then configures the APN settings automatically. You cannot edit them. In Origin OS Ocean you can open System/etc/apn-config.xml and you will see a list of every carrier in the world and read what default APN settings the operating system automatically configures the APN for that carrier to be.
I have the Vivo X Note with the same Origin OS Ocean firmware as the X70pro. My Canadian carrier supports VoLTE and WiFi calling and their tech support manually added the IMEI of my phone to the equipment list for my line and assured me that VoLTE and WiFi calling are provisioned for the line, but neither of those toggles appear in my Mobile Networks/Sim settings, because the APN that Vivo applies for my carrier doesn't support VoLTE. If I put the same SIM into my Samsung Note 20 Ultra 5g or my Huawei Mate 20 X and look at the APN settings, they permit VoLTE and the toggle and feature works on those phones - so it is not the carrier, or the SIM - it is Vivo and their default APN settings for your carrier.
I have a strong 5g signal here, and I can download and stream or do VoIP calls at 5g, but when I place a voice call it drops to 3g or H. That isn't an issue here in Canada, because we have kept our 3g voice network up and running. When I travel to the US, however, I can't place calls because without VoLTE enabled voice calls drop to 3g - which no longer exists in the United States. Someone needs to convince Vivo to change the apn-config.xml file to reflect APNs for North American carriers to ensure VoLTE is possible. I would just edit the .xml file myself, but you can't save changes to an .xml file without root, and we can't root because Vivo won't unlock the bootloader for Origin OS Ocean devices.

I don't think it's a Vivo problem. Carriers should give you access. As said before after 2 days I have Volte and HD icon even if device is not ufficial supported. I didn't change or touch anything. If your carrier uses a restricted policy on 5G or Volte there is nothing you can do.

My experience with VoLTE is kinda weird, settings show me that I have both VoLTE and VoWiFi enabled. But none of them really work. It's true that obviously system recognize that, send me a notice that I could have VoLTE enabled and routes me to the message to my provider. And even more thrilled - I can toggle VoLTE in settings, get the HD voice sign in notification bar, but I don't have any VoLTE. The only direct consequence of the toggle is that I lose the caller's name in the phone, every caller becomes the unknown number. But my provider is not trustworthy, the other users have issues with VoLTE, I frankly don't know anyone who has it enabled. Thus, I tried my wife's sim and didn't get even option to enable VoLTE. My wife has a Chinese (Honor) phone and both VoLTE and VoWiFi work with this phone flawlessly. That's why I assume that the problem is on Vivo's side.
