"I hear that the two of you are off to Galar, so I decided to bring you both a gift," Oak said as he produced a pair of deactivated cell phones. "These latest model Pokédexes include information on pokémon that were discovered in the Galar Region." Oak went on to explain that these Pokédexes are powered by Rotoms. Liam however had opted to update his older pokédex in place of getting a RotomDex. Oak explained that he had caught an extra Rotom on the way here that Liam could have for his Pokédex. Oak sent out that Rotom which possessed Liam's SIM card and swapped to the new phone and copied all of the info Liam's phone into the new one. It floated up and took a photo of Liam and began to process the set-up.
 "Thanks, Prof," Liam said with a smile.
