No 5g Connectivity

I am writing to seek technical assistance regarding persistent 5G connectivity issues with my Samsung Galaxy Note 20 Ultra 5G, model number SM-N986B/DS, which I purchased in the UK. 

I am currently located in Nakuru, Kenya, and using an Airtel Kenya 5G SIM card with an active 5G plan in a confirmed 5G coverage area.

The core issue is that my device consistently shows "ENDC Inactive" when checking the Service Mode via *#0011# in the NR (New Radio) section. Consequently, I am unable to access 5G speeds, despite being in a strong 5G signal area.

I have performed extensive troubleshooting, and the evidence strongly suggests the issue is related to carrier provisioning rather than a device fault. Here's a summary of my findings:

  1. Device Hardware Compatibility: My SM-N986B/DS model supports all common 5G bands, including those utilized by Airtel Kenya (e.g., n78, n40, n3). This has been verified through technical specifications.

  2. SIM Card Functionality: My Airtel Kenya 5G SIM card successfully connects to 5G and achieves "ENDC Active" status when placed in other 5G-compatible devices (e.g., [mention a generic example like "another brand's 5G phone" or "a different Samsung 5G model if you've tested one"]) in the exact same location. This confirms that my SIM, my plan, and the network coverage are all functioning for 5G.

  3. Extensive Device-Side Troubleshooting Performed:

    • My phone's firmware is updated to the latest available version.

    • Network settings have been reset.

    • I have attempted to stabilize the Country Specific Code (CSC) of the device to optimize for general European/international compatibility.

    • I have even used ADB commands (adb shell settings put global preferred_network_mode 20) to attempt to force the "NR Only" network type, and cycled airplane mode/rebooted, but the "ENDC Inactive" status persists.

  4. Carrier Response: Airtel Kenya customer service insists the issue lies with my phone. However, they have been unable to provide any specific technical reason why my particular IMEI is not being provisioned for 5G ENDC on their network, despite the above evidence. They have advised me to seek confirmation from a Samsung service center that my device is fully functional.

My Request to Samsung UK Support:

I require your expert assessment and, if possible, a formal statement or diagnostic report confirming the full 5G functionality of my Samsung Galaxy Note 20 Ultra 5G (SM-N986B/DS), IMEI. This would primarily involve confirming:

  • That the device's modem and associated hardware components are fully functional for 5G connectivity.

  • That there are no known hardware or software defects on the device side that would prevent it from achieving an ENDC Active 5G connection, given a properly provisioned SIM and network.

Hi,
If your Samsung Galaxy phone isn't connecting to 5G, the issue could stem from a few different areas. First, verify your phone's software and carrier settings are up-to-date, and that you have a 5G data plan and are in a 5G coverage area. You might also need to manually enable 5G in your phone's settings and ensure the network mode is set to 5G/LTE/3G/2G (auto connect). If these steps don't resolve the issue, try resetting your network settings, restarting your phone, or even checking with your carrier for any potential account or service issues. 

Here's a more detailed breakdown of troubleshooting steps:

1. Verify 5G is Enabled and Supported:

Check your plan: Make sure your mobile carrier plan includes 5G access. 

Confirm 5G coverage: Ensure you're in an area with 5G network coverage. 

Enable 5G on your phone: Navigate to Settings > Connections > Mobile networks > Network mode and select the option that includes 5G (e.g., "5G/LTE/3G/2G (auto connect)"). 

2. Update Software and Carrier Settings:

Software update: Go to Settings > Software update and check for any available updates.

Carrier settings update: Go to Settings > Connections > Mobile networks > Network operators and select your carrier to update carrier settings. 

3. Network Reset and Phone Restart:

Reset network settings: Go to Settings > General management > Reset > Reset network settings. 

Restart your phone: Turn your phone off and back on. 

4. Check for Potential Hardware Issues:

SIM card:

Older SIM cards may not be compatible with 5G. You might need to get a replacement SIM card from your carrier.

Phone compatibility:

Verify that your phone model supports 5G, especially if it's an older device. 

5. Contact your Carrier:

If the issue persists, contact your mobile service provider's support team. They can check for any network issues or account problems on their end and offer specific advice for your phone and plan

Thank you for the info. I tried ALL these steps before contacting support. Apparently Samsung phones are tightly region-specific when it comes to active and inactive network selections. Gladly, I was advise to go to the nearest Samsung center to get a compatible software ideal for my region. I hope this will activate my long waited 5g connection
