Part 1. How to Check Samsung Signal Quality Using #0011# Code

If you’re dealing with call drops, slow data, or poor audio during calls, checking your Samsung Galaxy’s signal quality can help identify the root cause.

Steps to Check Mobile Signal Quality on Samsung Using *#0011# Code

• Open the Phone app as if you're about to dial a number.
• Enter the code *#0011# and tap the Call button. This will launch the Service Mode screen on your Samsung device.
• If prompted, select the appropriate SIM card stack (STACK 1 or STACK 2) depending on which SIM slot is active.

Secret Code to Boost Samsung Signal

Many people believe that dialing the secret code *3370# or #3370# on a Samsung phone can boost cellular signal. In reality, this code doesn't improve signal strength. It was originally used to enable the Enhanced Full Rate (EFR) Codec, which was designed to enhance voice quality on older GSM devices not boost reception.

If you're looking to genuinely improve your Samsung phone's network signal, your best option is to invest in a dedicated Samsung signal booster designed to enhance cellular performance.
