Recent update created issues to sim

[somya_1407]

Hi,

I am using samsung galaxy s25 ultra, and after the recent update ( UI 7.0), I cannot connect to internet through sim network. Wifi is working fine. And when I am trying to switch the network, it is also not opening sim manager , saying unable to connect to esim. 

For airtel, the APN also disappeared. I have tried resetting all the network settings, that did not help either. Can anyone help?

After a One UI 7 update, issues like missing APN, eSIM not connecting, and no mobile data on your Samsung S25 Ultra are known problems for some users. Here’s how to fix it:

🔧 Troubleshooting Steps

1. *Restore Essential Samsung System Apps*
If you’ve removed or disabled Samsung eSIM services, they need to be restored:

- Reinstall *SamsungEuiccService (com.samsung.euicc)* via an ADB-uninstaller or backup tool—this service is vital for eSIM and SIM Manager functionality [1] .

2. *Reset Mobile Network Settings & APN*
- Go to *Settings → Connections → Mobile networks → Access Point Names*, tap the three-dots menu and choose *Reset to default*.
- If APNs are missing, add Airtel’s APN manually or let it auto-create. Known issue: APNs often get wiped after major updates [2] [3] .

3. *Toggle Airplane Mode or Restart*
- Turn Airplane Mode *ON → wait 30s → OFF*; then *restart your phone* to re-establish eSIM carrier config [4] .

4. *Ensure SIM card & slot are working*
- Remove, clean, and reinsert physical SIM.
- Test with a different SIM to rule out hardware issues [5] .

5. *Boot into Safe Mode or Clear Cache*
- Boot into Safe Mode to check for 3rd-party conflicts.
- Boot into Recovery Mode and perform *Wipe Cache Partition* to clean any corrupted system cache.

✅ What You Should Do Now

| Step | Action |
|------|--------|
| 1 | Restore SamsungEuiccService if disabled |
| 2 | Reset or manually configure APN for Airtel |
| 3 | Toggle Airplane Mode and reboot phone |
| 4 | Test SIM in another slot/device |
| 5 | If still unresolved, open *Error Report* in Samsung Members |

Multiple users on the Samsung forums have resolved this issue by restoring eSIM service and resetting network settings [1] [6] . If it still persists after these steps, the next Samsung patch will likely address it.


If it helps, please 'accept solution' from the three-dot menu in the comment. I will be happy.😊🙏

Hey Somya,
How did you resolve your issue?
I am facing this exact same trouble after today's security patch update.

[somya_1407]

It got resolved in few weeks automatically. I did not do anything, just kept using the data pack of another sim and avoided switching the sims

Thanks Somya! Good to know.
I went to the service center and got to know that my SIM card was damaged and thus messing with the DNS 🤭
Alas, I replaced the SIM, and the issue got resolved. However, thanks for your response and help! It's sweet of you. ✨️
