How to transfer iMessage texts from Mac to iPhone?

I accidentally deleted some messages from my iPhone but they still appear on my Mac as I haven't enabled iCloud for messages on either device. Is there any way to transfer the old messages from my mac to my phone?

Solution 1:

Yes, you can still sync them through iCloud. Try the following:

• If possible, make a Time Machine backup (no troubles expected, it's just good idea to make a backup of important info that you have only in one place);
• Enable iCloud sync for messages on Mac;
• Leave it charging and on Wi-Fi for several hours so messages could sync.
• Enable iCloud sync for messages on the phone;
• Tap "Merge" when prompted;
• Leave the phone on Wi-Fi and charging so messages could sync.
