Is there a way(without computer)to move my texts from my iPad to my IPhone? ICloud backup? Had to restore phone to last backup and lost texts?

Hi, yesterday I had to reset my phone (IPhone 8 plus) to factory default and restore it to its last backup (April 15th). I also have an iPad mini, which everything is Synced. I got everything back on my phone (up to date) except my text messages. I'm not able to access my computer right now and have read you can get them back my backing up you messages to ICloud. Is there anything I can do to get them back on my phone (they are still on my iPad mini), without using my Mac?

Only it you backed it up to the cloud BEFORE you reset it to factory default settings.
