I have Unlocked Samsung Galaxy S20 Ultra and the network was working perfectly fine, and then after that, my Galaxy S20 Ultra shows No Service and it can only be connected to wifi.
Can you tell me which component on the motherboard that causing my Galaxy S20 Ultra shows No Service?

If service was worked before, looks like there's a software trouble rather than hardware. Unlocking was not properly done so phone doesn't see the cell towers.

My device is SM-G988U1 Factory Unlocked. The device is able to regonice my SIM Card but unable to connect to network.
@leconlance50432 components responding for networks are antennas, RF amplifiers, RF encoders, usually located in radio block. Also there's can be a software problem.
Same thing on my Galaxy Note 20 Ultra Motherboard, the network works normal.but the motherboard has a broken LCD connector. When replacing the LCD Connector, the motherboard needs to be heat up, after replacing the LCD connector, the screen is able to turn on, but the motherboard has No Service.
