Let’s understand the issue first.
What Is the 345186# Code Used For?
USSD codes like 345186# are used by telecom networks to provide services directly through dialing, without internet access.
Depending on your network and region, this code may be used for:
• Package activation
• Offer information
• Account services
• Promotional bundles
• Customer options menu
If the code stops responding, it means your phone is unable to connect to the network’s service server.
Why Is 345186# Not Responding?
There isn’t only one reason behind this problem. Multiple technical factors can cause the code to stop working.
Here are the most common causes reported by users.
Network Signal Issues
If your mobile signal is weak or unstable, USSD requests may fail. Codes require a stable connection to communicate with the operator’s system.
In areas with low coverage or inside buildings, codes sometimes fail to respond.
Temporary Network Server Problem
Sometimes the telecom operator’s servers go down temporarily due to maintenance or overload. During this time, USSD services may stop working for many users.
Usually, service resumes automatically after some time.
SIM Card Error
A damaged, old, or improperly inserted SIM card can block service communication. Dust or scratches on the SIM chip may also cause problems.
Phone Software Issue
Software glitches or system bugs in smartphones sometimes block USSD communication. This usually happens after:
• Software updates
• Network setting changes
• App conflicts
Restarting often fixes it.
Network Mode Settings Problem
If your phone is stuck in 4G-only or incorrect network mode, some USSD services may not process correctly.
Switching network mode often solves the issue.
USSD Code Format Problem
Typing errors or modified codes can result in no response. Sometimes copy-pasting codes adds hidden characters that break the command.
Always type codes manually.

Steps:

Note: This removes saved Wi-Fi and Bluetooth connections.
Try Another Phone
Insert your SIM into another phone and try the code. If it works, your phone may have a software issue.
