If I buy a new phone from Republic wireless can I transfer my photos and contacts from my IPhone to my new phone?
as you will want a google account on an android phone i would set one up
for photos I recommend backing them up to the google cloud via the google photo app (I done this on an ipad)
for contact I would on a computer log in to the icloud and export to a .csv file then log in to https://contacts.google.com/ and import them from the .csv file (click the 3 bar menu icon then under more)
I do have a Google account and my contacts and photos are in there. Would they transfer over to my new Android phone?
Contacts will sync if you use the same Google account on your phone.
For Photos and Videos, you will need to use the Google Photos app.
