iCloud syncing needs a strong Wi-Fi connection. If your iPhone is out of internet service, connect it with a stable Wi-Fi network. If your iPhone has a poor network, change to another strong one. Or disconnect your device from Wi-Fi and reconnect to it to improve the situation.
If there is still no solution, resetting the network settings would be an effective way to consider. And this will wipe out the Wi-Fi passwords. You need to enter them again.
Open Settings > tap on General > scroll down and tap on Reset > tap Reset Network Settings > Enter your Passcode and confirm.
Each iDevice user gets free 5GB iCloud storage space. If the iCloud storage is exhausted, you can consider buying more iCloud storage, free up space by deleting unwanted photos/contacts/other documents or reduce the file size by removing unneeded messages.
If you need to sync messages from iPhone to Mac, you must log into the same Apple ID on both devices.
