Thanks for reaching out to us! We see that you are interested in the Galaxy A35 5G. To transfer data from another Android phone to a Samsung Galaxy phone, you should be able to use the Smart Switch app to move data like contacts, photos, music, and more. Samsung Smart Switch allows you to transfer contacts, photos, music, videos, messages, notes, calendars, and more to almost any Samsung Galaxy device. Make sure that Smart Switch is still compatible with your device by downloading the app from Google Play. As far as using the phone abroad, we recommend reaching out to your specific phone carrier for additional information. If you have any other questions, don't forget to reach out to us at Support. -Kelvin
