Setting up a new phone with an icloud backup
I recently bought an iphone 8, as my iphone 6 was having battery issues and a screen crack. When i went into Verizon store, the sales person there said he could transfer the number and everything over to my new phone. I left the two phones with him and went to get dinner. When i got back, he said i didnt have an icloud backup so he set up the phone without it, used some file transfer service, and called it a day.
As a result basically nothing is working. Ive got dozens of apps i need to install and sign into. My email is linked to the wrong email. All the weird default apps are cluttering up my screen. It will take me all weekend to get it in working order.
Can i get on wifi at home, and on my old phone which no longer is connected to my phone number, create an icloud backup. Then use that backup on the new phone to get make my phone basically the exact same as it was?
