The SIM card reader board is the small circuit that lets your phone read the SIM card and know which network to connect to. When it fails, you may see “No SIM” or lose signal even with a working card.
How to tell this is the right board for your vivo S17 Pro
This OEM reader board is made for the vivo S17 Pro 5G, model V2284A. Check the model number printed on the back of your phone or in the settings menu before you order, so you get the exact match.
- vivo S17 Pro 5G
- Model number V2284A
The board is a direct replacement part. It is sold as a single OEM piece, ready to fit into the phone in place of the faulty one.
Before you start, make sure the new board matches the model number above. A board for a different vivo model will not line up with the connectors inside the phone.
