I had Lumia 920. Due to issues with phone, I had to switch to Lumia 1320.
I have few important SMS communications done in Lumia 920. Can you please help me, how to copy all the messages from Lumia 920 to Lumia 1320.
On both phones, go to Settings>Backup>Text Messages and turn on the text message backup. It might take a bit, but your Lumia 920 will begin uploading your SMS to OneDrive and your new 1320 will download them back down.
