How do I update my voicemail greeting on iPhone 16 Pro Max after using the SIM in an old iPhone SE?

Hi,

I’m hoping someone can help with an issue I’m having.

I have an iPhone 16 Pro Max with two SIMs: an EE eSIM for my personal number and a physical Vodafone UK SIM for my work number.

When I went on holiday to Sri Lanka in March 2025, I took the Vodafone SIM out of my main phone and put it into an old iPhone SE so I wouldn’t get work calls while I was away. When I got back, I reset the iPhone SE and moved the SIM back into my iPhone 16 Pro Max.

Since then, my voicemail still tells callers that I’m on annual leave, even though I’ve updated it through Vodafone. When I call my voicemail to check, it plays the correct, updated greeting.

I’m wondering if this issue might be related to using the SIM in the old iPhone SE.

Any advice would be greatly appreciated.

Thanks!

Voicemail is a phone carrier feature escalate the issue with yours.

“Since then, my voicemail still tells callers that I’m on annual leave, even though I’ve updated it through Vodafone. When I call my voicemail to check, it plays the correct, updated greeting.”

That is illogical, nay impossible. Are you sure the callers are not being forwarded to your EE voicemail. Have you charged your EE message?
