行動網路無法連線？三星手機簡易解決方案 / Mobile Network Not Connecting? Easy Solutions for Samsung Phones

如果手機無法連上4G或5G網路，除了重開機或短暫切換成飛航模式之外，還可以將SIM卡的網路模式暫時切換，讓4G或5G網路斷線後重連，這樣就可以讓行動網路重新運作了。

If your phone can't connect to a 4G or 5G network, besides restarting your phone or briefly switching to airplane mode, you can also temporarily switch the network mode of your SIM card to disconnect and reconnect to the 4G or 5G network. This can get your mobile network working again.
