I have a problem with the network, I have two O2 and Telecom cards in my phone. On my o2 card, it connects to HSPD and switches to 5G only after a restart. If I lose the 5G signal, the phone will not switch to 4G but to HSPD and will not switch back to 5G by itself until I restart the phone. It doesn't work on a card from Telecom. Can you help me with this?
