Missing voicemail

I recently purchased an iphone x to replace my iphone 7. The iphone 7 is now being used as a backup phone with a different number and sim card. The original sim card is in the new iphone x.
I had a number of very important, irreplaceable voicemails on the iphone 7 that did not transfer with the sim card to the iphone x.
Apple tells me that they cant help me but that AT&T has them on their server. I called AT&T and they told me to switch the sim card back to the old phone and the voicemails would reappear. They did not.....!
How can I retrieve the missing voicemails? Several of them were over a year old and had been left by my father and father-in-law before each of them passed away last year. Neither Apple nor AT&T seems able or willing to help me and they have to be somewhere because I didn't delete them!!

Since they are not on your phone

This is bad news since most voice mail systems delete after some number of days. Since they are not on your phone, only those folk that had them can answer.

My bet is they are gone.

Your prior voicemail

....won't be stored on the SIM card, it doesn't work that way. Voicemail is stored internally in the phone itself. I don't know if there is a simple method to transfer that from device to device.

Your cellular carrier CS rep has no access to assist you with recovery of VM and there is no tool for them to transfer it to your new phone, they can only confirm the feature is active and correct it if the feature is turned off . I worked for At&t /Cingular Customer Service for more than 10 years, including the year the first iPhone was sold.

Nobody is assuming you deleted the messages, unfortunately these things can happen.

Was your iPhone 7 damaged and required that you buy the X ? If so, there might be some options out there. Try an internet search through Google or post your question on the Apple site for a possible solution/suggestion.

Sorry to hear of the issue though.

Missing saved voicemail

The iphone 7 was not damaged. the voicemails had been on it for over a year. some were several years old. i dont think they should have automatically deleted due to age after all this time but obviously i dont know that. maybe it was something the at&t salesman did when he switched the sim card that cleared them out

As I mentioned....

....Voicemail is not stored on the SIM card as it only has up to 256 KB of storage, not to be confused with an SD card. With iPhones, it is stored in the phone memory. The SIM card doesn't have the memory capacity to store Voicemail.

One other suggestion is to insert an active SIM in the iPhone 7 phone to see if the messages show on the old phone.

I'd take that bet.

Handing the phone over to sales or techs is a dangerous move. Too bad you didn't hand over the SIM only. All bets are off in regards to what they did.

You are now another CNET member that is learning first hand why so much is written about backups of what we can't lose.

PS. I forgot to mention something of a last hope.
