I have linked both the numbers to my one iCloud, seems fine on my Mac, but on my phone not so, only certain contacts are missing, they are in my contacts but not displaying in messages.
iPhone 13 Pro
Update: I've noticed when I click the number in messages, then click info as if it is a contact, it has the option to add new contact or add to existing, so I add the number which always has +44 before the number, despite the 07 version already existing, this then seems to link the contact.
This seems the software is struggling to link messages from existing contacts when originating from +44 as opposed to just 07***** format.
Which maybe linked to which of my SIM cards is the default, as one is not a UK sim.
Not so much a fix, but a work around as it isn't too many contacts in question.

Also for those looking, I stumbled across this extensive set of fixes that might be of use...

Hello Aleksandr.J,
Welcome to Apple Support Communities. It sounds like you are missing contacts on your iPhone Messages.
We are happy to help. Try this: Go to Settings>Messages>MMS Messaging. Turn it off and then turn it on again.
Please let us know if it helps.
Cheers!
Thanks for trying that step for us, Aleksandr.J.
If you're using iCloud Contacts, this article has steps to take when they won't sync: If your iCloud Contacts, Calendars, or Reminders won’t sync - Apple Support
Have you checked your accounts to see if any of these have been turned off? This may account for missing contacts. Check out this article for the steps:
Manage and delete contacts on your iPhone, iPad, or iPod touch - Apple Support
"Turn Contacts on or off for an account
Want to add or remove all of the contacts from an account that you already set up? Just turn Contacts on or off for that account:
Choose a default account to add new contacts
If you set up multiple accounts in the Contacts app, you can choose a default account to add new contacts to. Just go to Settings > Contacts > Default Account and choose an account."
Regards.
Thanks for the reply, I know this one is a bit of a mystery.
I have tried these steps, but they wouldn't seem to relate to this specific issue. Though I have attempted to follow the steps anyway. Though several steps don't follow as you specify, such as... Settings > Contacts > Default Account and choose an account (This last step, isn't present.)
The issue is only with iCloud, I double checked and I don't have contacts turned on for any other mail account, to avoid such issues, it is all over iCloud.
There is also no such option for multiple accounts within the contacts app, do you mean groups?
This is iOS 15.5 for clarity.
To clarify the issue wouldn't seem to be with contacts, as my contacts appear fine in the contacts app. They are all present and correct, I have turned off iCloud contacts and deleted from phone and turned them back on and they appear on my phone again, fine. Multiple times. The issue is seemingly within messages, a handful of contacts don't show - just appear as the numbers. But these specific contacts are in my contacts lists all fine. They were also always fine prior to this upgrade.
For interest if I turn on the 'filter unknown senders' in settings>messages, then go to the unknown senders tab in messages, it is empty, the 'missing' contacts in question are in the known senders list implying the software recognises they are in my contacts, yet doesn't display the data accordingly in messages.
Also all of these same contacts appear and sync and operate fine within the messages app on my Mac, which has the same, one and only linked iCloud account logged in, implying again the issue isn't with my account or the contacts, it is purely an issue on my phone and apparently just wishing the messages app.
Really appreciate the assistance on this one, as a former FRS at Covent Garden (though over 10 years ago now - so way out of my depth these days), I know the pain of trouble shooting such issues in person. Let alone remotely.
Thanks again.
Hello thanks for jumping in.
I have tried turning MMS off and on for both sims. But no change. 🤔
Some contacts missing in messages on phone after upgrade and dual sim use
