Hi, could you please help me run the following test as well:

Please insert the same SIM card into your phone and enable hotspot on the phone, then connect another client device to the hotspot. You could try to call the SIM number and check if the phone will still stay on 4G and if internet still works.

Thank you very much.

@TP-Link 

I tried the suggested test with the same SIM and the result is successful (phone call and internet working at the same time).

Thanks

@jimmy6500 With similar problem TP-link ha changed my router.

Now phone works with Very mobile SIM, nt with Ho mobile SIM.

@TP-Link 
Hello, I've the same problem stated in the first post:
internet and sms working, analog phone not.
It's impossible to receive or do phone calls, if someone try to call me, he receive a notification saying "the phone could be off or out of signal coverage".

I made the test you suggested to other users and the sim is correctly working with VoLTE in a smartphone while the hotspot is active.

The hardware version of my router is V1, and the firmware is the latest one.
I bought this modem on Amazon so not connected to a specific isp.
I'm using the Ho-Mobile Italian isp that support LTE/VoLTE.

Please solve this problem
 

I recently bought a brand new TL MR-6500v, connected a landline phone and it didn't work
So is there any way to connect to the landline?

@TheDavid 

Same problem. HO-mobile does not enable the VOLTE for modems. Can it be solved with firmware update? I'm happy not to surf when I phone (No VOLTE)

@Albert-dokker  Until 30 days ago everything was working perfectly :(

@TP-Link  I've replied to senio engineer, thanks

@TheDavid it is because they have abandoned the 3G network

With Very Mobile (IT) and VoLTE enabled, is impossible to send SMS messages (same error in debug logs).

SMS receive and phone calls seem works fine.
