iPhone 15 Pro Max – SIM Failure After iOS 26.0.1 Update

Hello,

After updating my iPhone 15 Pro Max to iOS 26.0.1, both my eSIM and physical SIM stopped working. It shows “SIM Failure” and I have no network on either SIM.

I have already tried the following steps, but the issue still remains:

• 
  
• Reset Network Settings
• 
  
• 
  
• Changed my physical SIM card
• 
  
• 
  
• Restarted and fully reset my iPhone
• 
  
• 
  
• Reinstalled eSIM
• 
  

Despite all this, the problem is still there.

Has anyone faced a similar issue after the 26.0.1 update? Is there any solution or fix available?

Thank you in advance for your help!
