Hi Glen, Yes you can use most aspects of the phone without a SIM card. The part which specifically won't work is making / receiving phone calls and text messages (the SIM card is the chip which has your phone number in it and also which telephone company you are with). With no SIM card, the only way to access the internet will be via WiFi. When you aren't connected to the internet, you won't be able to access anything online such as web sites, email or some apps. Regards Quentin.

To post to the list, simply send email to vi-android@xxxxxxxxxxxxx. To unsubscribe from the list send an email to vi-android-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field (new users, use 'subscribe' to subscribe) To receive the list as a digest, send an email to vi-android-request@xxxxxxxxxxxxx with 'set vi-android digest' in the subject (to go back to receiving every message use 'unset vi-android digest' in the subject).
