After a phone call: No connection to mobile data?

Dear Community,

I've had an extremely annoying problem with my phone's internet connection for ages. I've had a new one for two days now and lo and behold: the problem is even more annoying than before. But one after anonther:

With my old device (Huawei Nova) I lost the mobile internet connection every time I called someone or someone called me. No connection was established after the conversation. Only after manually selecting the network operator in the settings could the device reconnect and it worked until the next phone call. Then the same again. It was annoying, but I could live with it.

With the new device (Huawei P30), the problem has worsened. Now, even after restarting the device, I only have a sporadic internet connection, which is of course completely gone after a phone call. I can no longer establish the connection even using the manual selection of the network operator. In other words: if I'm lucky enough to have a mobile data connection after switching on the device, it is completely interrupted after a phone call and can't be switched on manually.

In order to hopefully come straight to the right solution, here is a list of things that I have already tried:

APN settings checked
new SIM card requested (2x)
Using the developer options, two ticks for "mobile data always active" and "LTE carrier agregation -> LTE highspeed mode on" are set (that should help according to another thread)
Restart the phone
Software updated
SIM card inserted in another mobile phone -> same problem

As you can see, I've already tried a lot and I'm at the end of my game. And the service line employees talk the same stuff every time that doesn't help. That's why I ask the experts among you for help. Has anyone ever had a similar problem or an idea what could be wrongly set or what is the reason? Incidentally, the adored is bob, the low-cost division of A1.

Hi, the P30 is a dream device. I try to make my ex jealous by giving my son a P40.

It's not the device. 2 broken cell phones?

Normally it runs in the house via Wi-Fi.

Wi-Fi disconnected? Look in the properties, network connections. There can be. Switched off.

You can see it at the top left. If it says 3G or 4 G, you have no Wi-Fi. Circles that grow larger towards the top. Wireless Internet access.

Every bus, train, Mcdonald, Burgerking has it. An open Wi-Fi. Recognizes the smartphone immediately and asks whether it should log in there. PW "Public" after that you never had to enter it again.

Password is "public"

Something is going wrong at home…

You don't have Wi-Fi. Router ancient?

Then apply for a current one. For free. Call Tel Company. You need a new router.
