Bsnl 4g Network issue only in Samsung.

[LiveYongLiveFree]

Something wrong in Samsung galaxy M04 with BSNL 4G VoLTE sim.... 4G automatically switch to 3G even srong 4G signal available at our location as bsnl tower is nearly around 1km from my home so we are getting 700mhz high speed bsnl 4g network. I am facing an issue that network automatically switch to 3g even network mode is in 2g,3g,4g auto. In my area BSNL 4g have good coverage even though my bsnl sim getting 4g when inserted in another brand mobile but in M04 4g switch automatically to 3G after one or two days even in the same location. For getting 4g network again i have to manually switch network to 

3g,2g auto then again to 4g,3g,2g auto or restart device which is terrible. Tried resetting APN but it works only for 1/2 days after that again switch to 3G. I recommended bsnl 4g to my neighbor who have OPPO device still he is getting 4g so the 4g network is stable in our area.. The problem is with my device! Samsung should rollout an OTA update for M04 optimised for bsnl 4g. 

Another issue is that outgoing call will not connect in 4g at first time when I dial a number but connects when I cut the call and dial the number again. 

Getting only bsnl 3g network even network mode is in Lte,3g, 2g auto.

The issues you're experiencing with your Samsung Galaxy M04 and the BSNL 4G network appear to be device-specific, rather than a problem with BSNL's network itself. Here's a breakdown of the problems and potential solutions:
1. Automatic Switching to 3G:
* Device Incompatibility: It's possible that your M04 might have compatibility issues with the specific 4G bands used by BSNL in your area, particularly the 700MHz band. While your neighbor's OPPO device works fine, the M04 might not be optimized for this frequency.
* Software Bug: There could be a software bug or glitch within the M04's firmware that causes it to intermittently drop 4G connectivity and revert to 3G.
2. Outgoing Call Issues:
* VoLTE Instability: The initial failure to connect outgoing calls on 4G might be related to VoLTE (Voice over LTE) instability. VoLTE allows for high-quality voice calls over the 4G network, but it can sometimes experience glitches or delays in establishing a connection.
Troubleshooting Steps:
* Software Update: Check for software updates for your M04. Samsung occasionally releases updates that address bugs, improve performance, and enhance compatibility with different networks.
* Network Settings Reset: Reset your network settings. This will clear any saved network configurations that might be causing interference.
* Go to Settings > General Management > Reset > Reset Network Settings.
* Safe Mode: Restart your phone in safe mode to see if any third-party apps are interfering with network connectivity.
* Power off your phone.
* Press and hold the power button until the Samsung logo appears.
* When the Samsung logo appears, release the power button and immediately press and hold the volume down button.
* Your phone will start in safe mode. If the problem disappears in safe mode, a third-party app is likely the culprit.
* Contact Samsung Support: If the issue persists, contact Samsung support for assistance. They might be able to provide further troubleshooting steps or suggest a software repair.
* Contact BSNL Support: While the issue seems device-related, it's worth contacting BSNL support to rule out any network-specific problems in your area.
Additional Considerations:
* Signal Strength: Ensure you have a strong and stable 4G signal in your location. Weak signals can sometimes lead to network drops.
* SIM Card: Try using a different BSNL SIM card in your M04 to see if the problem persists.
By following these steps, you can hopefully pinpoint the cause of the issue and find a solution that allows you to enjoy a stable and reliable 4G connection on your Samsung Galaxy M04 with your BSNL SIM card.

But there is no update released for M04 since oct 2024.

I understand. Either you wait for an update if you are eligible or try a factory reset. If after a factory reset if it still fails to address your problem you may want to take it to Samsung Care.

Now it automatically switch to 3G
Even after resetting mobile network settings 🙄 as you said this is due to BSNL 4G compatibility issues with M04 only samsung can do anything by pushing an update for BSNL 4G compatibility.
