network provider services on iPhone - underneath Data roaming toggle

Hi ​@Mackie65, 
 

Thanks for the detail I’ll clear this up properly for you.

What you’re seeing under “Network Provider Services” → “iD Services” → “Mail” on your iPhone is not something to worry about, and it’s not a second active number on your account.

📱 What that number actually is

That number is typically:

• A network service number linked to iD Mobile (often used for things like voicemail or carrier services)
• Or a carrier identification number stored on the SIM/eSIM for service routing

It can sometimes look like a normal mobile number, but it isn’t your usable number and you won’t be billed for it.

✅ What matters

Since you’ve said:

• Your number has successfully ported over ✔️
• Roaming is enabled ✔️

That means your service is set up correctly.

Your actual number is the one that:

• Shows in Settings → Phone → My Number
• Is the one people can call/text you on

👍 Quick optional check (recommended)

Just to be thorough:

• Go to Settings → Messages → Send & Receive
• Make sure your ported number is ticked

If not please follow the instructions on the link below:
