I'm using a
Samsung Galaxy S20 FE 4G and every time I enter a building's basement, even for just a short time period, the connection is cut and my phone looses it's connection to the mobile network.
(Sometimes it also just happens randomly and I only notice it once a song stops playing in the background).
I can still connect to WI-FI, but the 4 bars disappear and I'm not receiving any signal/connection, until I completely restart my phone or take out my SIM-card and put it in again, which probably restarts the SIM-driver.
Is it possible to manually restart the SIM-driver, which does not require me to restart my phone, nor take out my SIM-card?
(And is there an answer to why my phone is even doing this in the first place?)
Thank you very much!
