Two possible agreements
Locate the airtime documents and any separate device payment agreement. Read the end dates and outstanding obligations individually.
Upgrade eligibility
Ask Three about the exact upgrade route on the account. A device return or early change can have condition and timing requirements. Obtain confirmation before sending the existing phone away.
The existing SIM
Follow Three’s guidance about using a SIM after upgrading. eSIM transfer, replacement and physical SIM reuse can depend on the phone and account.
Backups and verification
Back up the phone, retain verification access and avoid erasing the old device too early. A number belongs to the service; photographs and applications belong to the handset backup.
