SUN 1020B SIM Card Reader 1.0

SUN 1020B SIM Card Reader is a straightforward utility for accessing and managing the data stored on standard SIM cards using a compatible 1020B USB reader. It helps you back up contacts, review SIM-stored messages where supported, and perform basic security and maintenance tasks—all from your desktop.

Key features:

• Read and manage SIM phonebook entries (names and numbers)
• Import and export contacts to common formats (CSV, VCF)
• View and back up SMS stored on the SIM, when supported by your card and region
• Enable/disable and change the SIM PIN; guided PUK entry when required by your carrier
• Batch edit, merge, and deduplicate contacts before writing back to the SIM
• Create full SIM backups and restore them later
• Connection diagnostics to help troubleshoot reader or driver issues
• Clear, wizard-style workflows for quick setup and use

Requirements:

• SUN 1020B-compatible SIM card reader and a standard 3V/5V SIM card
• Appropriate drivers for your operating system; consult your reader’s documentation

Notes:

• All operations are performed locally on your computer; data is not uploaded unless you choose to export it
• Features may vary by SIM type, carrier settings, and regional regulations
• Do not attempt to clone SIMs or bypass security controls; always follow local laws and carrier policies

Ideal for anyone migrating to a new device, archiving legacy SIM contacts, or keeping an extra backup of critical phonebook entries.
