Pixel 7 unable to connect to mobile network despite valid SIM/eSIM

Hi,

I have been experiencing mobile network issues for about a week and I’m running out of ideas.

I am using a Google Pixel 7 on Sosh (Orange France). I have been using this phone for about 4 months without any problems. Then, one day, without any apparent trigger (no drop, update, water damage, or configuration change), the mobile network stopped working.

The SIM is detected correctly, but the phone shows “Emergency calls only”. The issue is intermittent: occasionally I can make calls or use mobile data for a few minutes, but then the connection is lost again.

Wi-Fi works normally, and I can make calls and send texts over Wi-Fi.

Here is what I have tested so far:

  • My SIM card works normally in another phone.

  • A different SIM card also fails in my phone.

  • I contacted Sosh, and they performed a network reset on their side.

  • I reset the network settings on the phone.

  • I restarted the phone multiple times.

  • I manually reconfigured the APN settings.

  • Thinking it might be a problem with the physical SIM connection, I switched from a physical SIM to an eSIM. The problem remained exactly the same.

Based on these tests, it seems unlikely that the SIM card, eSIM, or carrier account is the cause. At this point, I suspect either a hardware issue (modem, antenna, etc.) or a software/firmware problem.

The issue first appeared while I was running e/OS/ 3.7.3-panther. I have since upgraded to 4.0, but the problem persists.

Does anyone have suggestions for additional troubleshooting steps or a way to determine whether this is a hardware or software issue?

Thanks for your help

Since a new APN system for AOSP ~early 2026 some ideas for troubleshooting include special attention to actively harmonising the APN data:

  • on your SIM card,
  • provided on /e/OS install and
  • your carrier’s latest APN.

APN will likely fail if the SIM card data (for any reason) cannot be updated to exact current values. Understood; many of the following you did.

In case of difficulties one can ask the carrier to do an APN reset OTA (Over The Air) … alternatively

Manual APN Configuration

Ensure you have a good Wi-Fi connection.

Open Settings :magnifying_glass_tilted_left: Search APN … or

Navigate to Mobile Networks:

Tap on Wireless & networks or Connections.

Select Mobile networks or Mobile data.

Access APN Settings:

Tap on Access Point Names or APN.

Add New APN:

Tap on the ‘+’ icon or Add button to create a new APN.

Enter APN Details:

Fill in the required fields based on your carrier’s specifications.

Save APN Settings:

Tap on Save or the checkmark icon to save the new APN.

It is OK if Save takes a while complete … implies the the settings have been checked valid by the carrier. Note: Add new APN seems more likely to succeed than Edit existing.

Troubleshooting

If you encounter issues while setting APN, consider the following steps:

Reset to Default: Navigate to APN settings, tap on top right 3 dot menu, and select Reset to default.

Activate Airplane Mode: Enable Airplane mode, wait for a few seconds, and then disable it to refresh the network settings.

Remove SIM Card: Remove the SIM card, navigate to APN settings, make changes, reinsert the SIM, and restart the device.

Restart Device: Restart your phone while connected to Wi-Fi to refresh the network settings.

Carrier-Specific APN Settings

For specific APN settings, refer to your carrier’s documentation.

IMS Registration

In order for all data and call features to work you need to know that your IMS status is registered. A guide to dial INFO.

Update on my case. I’ve also described the problem on GitLab: pixel 7 panther no mobile internet (#9098) · Issues · e / Backlog · GitLab

What I’ve tested so far:

  • My SIM works normally in another phone.
  • New SIM issued by the operator: same behaviour.
  • eSIM instead of physical SIM: same behaviour.
  • Operator did a network reset on their side.
  • Network settings reset, APN manually reconfigured with the operator.
  • Clean install of /e/OS 4.1.1 (full factory flash, userdata and metadata erased): same behaviour.
  • Stock Google factory image, Android 15 BP1A.250505.005.B1: same behaviour.
  • Manual network selection lists all four French operators; selecting mine connects, but the phone stays on “no service”.
  • IMEI: two valid 15-digit numbers.
  • Wi-Fi calling works, so IMS registers fine over Wi-Fi.

So the software side is ruled out, the problem persists identically on Google’s own build. I’m waiting on my operator to check whether the IMEI is blacklisted (I bought the phone refurbished). If it comes back clean, it goes in for hardware repair. I’ll post the answer here.

Thanks a lot aibd for taking the time to look into this and for pointing me to the IMS thread !
I read through it, but I don’t think it applies to my case: Wi-Fi calling works fine on my phone, so IMS registers correctly. And in their case the problem disappears under the stock ROM, while mine persists identically on Google’s own build.
Still, it was worth checking and it helped me rule out one more possibility. Much appreciated !
