Redmi 9A No SIM Card No Network – Easy Fix Guide

📱 Redmi 9A No SIM Card No Network – What’s Going On?

If your Redmi 9A is showing “No SIM card” or no mobile network even after inserting a valid SIM, you’re not alone. This is a common issue faced by many users due to internal hardware faults, especially related to the SIM card connector or motherboard components.

Let’s break down what’s happening and how it can be fixed.

🔍 Symptoms of the Issue

• SIM card not detected at all
• No signal or network bars shown
• Network settings show “No SIM card”
• Unable to make or receive calls

As shown in the image above, one phone shows “No SIM card”, while another detects Jio 4G correctly – this clearly points to a hardware-level issue.

🛠️ Root Cause – Hardware Fault on the Motherboard

The image highlights a specific section of the motherboard that is often responsible for the issue. In many Redmi 9A devices, the tiny components connected to the SIM signal line or nearby capacitors get damaged or loose.

A simple hardware inspection and rework (like jumper or component replacement) in the marked area can bring back the SIM card detection and network signal.

✅ Fixing the Problem

Solution:

• Open the device carefully (only if you are experienced).
• Inspect the motherboard area shown in the image.
• Look for missing or damaged components.
• A professional technician can rework the area using micro-soldering.

⚠️ Note: If you're not comfortable opening the device, it’s best to visit a trusted technician to avoid further damage.
