##72786# not working

What is ##72786#?

##72786#, commonly known as a dialer code, is a special sequence of characters that can be entered into the phone’s dialer to trigger specific actions or access hidden settings. It plays a significant role in the functioning of mobile devices and is particularly relevant in the context of carrier-related operations.

The Purpose of ##72786#:

##72786# is often referred to as the “SCRTN” (Special Code to Reset the Network) code or the “##RTN#” code. Its primary purpose is to initiate a network-related procedure known as a “Carrier Reset” or “Sprint Network Reset.” This procedure is specific to devices operating on the Sprint network or MVNOs (Mobile Virtual Network Operators) that utilize Sprint’s infrastructure, like Tello.

What Does the Carrier Reset Do?

When the ##72786# code is dialed and activated, it triggers a series of actions on the device, including but not limited to:

  1. PRL Update: It updates the Preferred Roaming List (PRL) on the device. The PRL is a database containing information about the preferred roaming partners and networks that the device can connect to when outside its home network.
  2. Profile Update: It updates the device’s network profile, ensuring that it has the correct settings and configurations to access the carrier’s services effectively.
  3. Device Configurations: It refreshes various device configurations related to voice, data, and messaging, optimizing the overall network experience.
  4. Network Registration: It re-registers the device on the carrier’s network, ensuring a fresh connection and resolving potential network-related issues.

When Should You Use ##72786#? 

Carrier Reset using ##72786# is typically used in specific situations:

  • When experiencing network connectivity problems, such as no service, dropped calls, or slow data speeds.
  • After changing to a new SIM card or activating a new line on the same device to ensure seamless network integration.
  • If instructed to do so by the carrier’s customer support team while troubleshooting network-related issues.

How to use ##72786#?

Please note that the process may vary slightly depending on the device’s make and model. However, the general steps to perform a Carrier Reset using ##72786# are as follows:

  1. Open the phone’s dialer app.
  2. Enter ##72786# using the keypad.
  3. Press the “Call” button to initiate the code.
  4. Follow any on-screen prompts that may appear during the reset process.
  5. The device will automatically restart once the Carrier Reset is complete.

Reasons behind ##72786# not working issue

  1. Carrier Restrictions: Certain carriers may block the functionality of ##72786# on their networks. They may impose limitations to prevent users from accessing specific settings or diagnostic features.
  2. Incompatibility with Custom ROMs: Custom ROMs, which are modified versions of the phone’s operating system, can interfere with the execution of ##72786#. These customizations may disable or alter the code’s intended functions.
  3. Outdated Software Version: If the phone is running an older Android version, it might not support ##72786# or may encounter compatibility issues, hindering its proper execution.
  4. Device-Specific Limitations: Some devices from certain manufacturers might have inherent limitations that prevent ##72786# from functioning correctly.
  5. Network Connectivity Issues: If the phone has poor network reception or is in an area with weak signals, attempts to dial ##72786# may fail due to inadequate communication with the carrier’s server.
  6. Incorrect Dialer Input: Accidental typos or errors while entering the code could lead to ##72786# not working as intended.
  7. Temporary Network Glitches: At times, the carrier’s network or server may experience temporary glitches, affecting the execution of ##72786#.
  8. Carrier Account Status: If the device’s carrier account is inactive, suspended, or facing billing issues, ##72786# functionality may be restricted.
  9. Manufacturer-Specific Restrictions: Some phone manufacturers impose limitations on certain dialer codes for security or user experience reasons, affecting ##72786# functionality.
  10. Prevent Unauthorized Access: Carriers may limit the use of ##72786# to prevent unauthorized access to critical network settings, ensuring the device’s stability and security.

Understanding these reasons can help users diagnose and resolve the ##72786# not working issue efficiently. In case of persistent problems, it is advisable to contact the carrier’s customer support for further assistance and guidance.

How to fix ##72786# not working?

Fix 1: Manually Configuring APN Settings

One effective method to resolve the ##72786# not working issue is to manually configure the Access Point Name (APN) settings. The APN settings are crucial for establishing a proper connection with the carrier’s network and ensuring seamless data and voice services. Here’s a step-by-step guide to manually configure the APN settings:

  • Step 1: Access the Settings Menu: From the home screen, tap on the “Settings” app, represented by a gear icon.
  • Step 2: Locate Mobile Networks: In the “Settings” menu, scroll down and find the “Network & Internet” or “Connections” option. Tap on it to proceed.
  • Step 3: Access Mobile Network Settings: Within the “Network & Internet” or “Connections” menu, locate and select “Mobile Network” or “Mobile Data.”
  • Step 4: Access Access Point Names: Look for “Access Point Names” or “APN” and tap on it. This section contains the carrier-specific settings needed for proper network connectivity.
  • Step 5: Add a New APN: If you don’t see any existing APNs or the correct APN for your carrier, tap on the “+” or “Add” icon to create a new one.
  • Step 6: Enter the APN Details: Fill in the required fields with the correct APN details provided by your carrier. These details usually include:
  • Step 7: Save and Select the New APN
    • Once you have entered all the required details, tap on the three-dot menu (or similar) in the top-right corner and select “Save” or “Save APN.”
    • After saving the new APN, make sure to select it as the active APN by tapping on the radio button or the circular indicator next to the newly created APN.
  • Step 8: Reboot the Device: To apply the changes, reboot your device. After the restart, the device should have the updated APN settings, enhancing its compatibility with the carrier’s network.

  • Step 4: Select Network Mode: Look for “Preferred Network Type,” “Network Mode,” or a similar option. Tap on it to view available network modes.
  • Step 5: Choose CDMA Only: In the list of network modes, select “CDMA” or “CDMA Only.” This option might also be labeled as “CDMA/LTE” or “CDMA/EVDO.”
  • Step 6: Save the Setting: After selecting CDMA as the preferred network mode, tap on “Save” or “Apply” to confirm the changes.
  • Step 7: Reboot the Device: To apply the new network mode setting, reboot your device. Allow it to fully restart.

By setting the network mode to CDMA, you may potentially resolve any issues related to ##72786# and improve network connectivity. However, it’s important to note that CDMA-only mode may limit your device to 3G data speeds, so if you experience better network performance with other modes, consider switching back or testing different options to find the optimal setting for your specific location and carrier coverage. If the ##72786# issue persists, move on to other troubleshooting methods or seek assistance from your carrier’s customer support.

Fix 3: Checking for Aftermarket Phone Dialer Apps

If you have installed aftermarket phone dialer apps on your device, they might be interfering with the proper execution of ##72786#. These apps, designed to offer additional features like call blocking or spam filtering, can sometimes cause conflicts with carrier-specific codes. To check if an aftermarket dialer app is causing the issue, follow these steps:

  • Step 1: Access the Settings Menu: Open the “Settings” app on your device from the home screen.
  • Step 2: Navigate to Apps or Application Manager: Look for the “Apps” or “Application Manager” option in the Settings menu. The name may vary depending on the device’s make and model.
  • Step 3: Locate the Aftermarket Dialer App: Scroll through the list of installed apps and find the aftermarket dialer app you suspect might be causing conflicts.
  • Step 4: Disable or Uninstall the App: Once you’ve identified the app, you have two options-
    • Disable: Tap on the app and select “Disable” to turn off the app’s functionality temporarily. This will revert your device to the default phone dialer.
    • Uninstall: If you don’t need the aftermarket dialer app, tap on “Uninstall” to remove it completely from your device.
