Hello fhan,
Congratulations on joining the Samsung Developer Forums, we’re happy to have you with us !!
While setting up the wallet, the Samsung Blockchain Keystore performs required operations like checking for security updates, ensuring device integrity, and more. Network connectivity is a mandate for such operations, so it’s not possible to set up the wallet without connectivity. Sorry for the inconvenience.
Regards,
