Problem with infotainment and maps

[CyberNinja]

Hello, my EV3 is acting up. On a regular basis, it takes my SATNAV about ten to fifteen minutes to provide me with live access. A message reading "Network connection unstable On board navigation will be provided" is all I ever receive.
The message "Service not activated (KIA Connect) not subscribed" appears in the General section, under OTA - Infotainment and Map. However, after a ten to fifteen minute delay, it changes to "Activated."
I can connect to the EV3 through the KIA Connect app on my Android phone, and my KIA Connect account is active.
It doesn't matter how strong the mobile network signal is; this happens every time I use the car. It was a major pain to attempt to leave London without a working SATNAV.
If anyone has any ideas on how to fix this, please let me know.

That seems like something the Kia workshop could handle.

The car will display your phone's network signal; if the signal is weak, it could be because Kia uses Vodafone to connect to their server and back.
Does it operate faster if you drive it to a more open area?

The car's location appears to be unchanged. I can see where there is a strong signal on my mobile device—which is a Vodafone SIM—but it has no effect on EV3. There are instances when trips are completely disconnected, rendering the SatNav useless.

If you still have trouble, try briefly disconnecting the 12V battery or performing a pin hole reset on the infotainment system.

I've previously attempted both of those options without success.
I am grateful.

Thus, it may be a SIM problem in the vehicle.

A Kia dealer should look into it, in my opinion.
