The SIM card is not relevant to Activesync.  As long as the phone can connect to the Internet and has a working Data connection, and as long as your server enforces a minimum of a 4-digit PIN, then remote-wipe should work happily.

Hmm, I'm interested in the answer to that question too: What happens if the phone is stolen and the SIM card is changed.

Be aware that although you can require users to have a PIN on their mobile device, those PINs can be *easily* thwarted by resourceful users.  That applies to Android and iOS devices.  So don't depend on the PIN for total security.  Users hate entering that PIN all the time and some of them might try to disable it without informing you.

back your phone data up on a computer so if anything ever happens to your phone you can restore it all back to your replacement phone.

The Purpose of the PIN is to enable the Administrator to wipe the phone.  No PIN - No Remote Wipe.

Also make sure you set the Wipe Device after x many Failed Attempts.  That way if the thief tries to unlock the phone, the phone will be factory reset.

Any memory cards in the device will not get wiped if you remote wipe the phone.

The emails are stored in the phone and unless the PIN is known, there won't be easy access to them by the average thief.

If the SIM is switched, most times the battery will need removing, so to access the phone, the PIN will need to be entered to gain access and if incorrectly entered several times, the phone will be wiped.

Alan, you are the best but I still stubbornly like to point out to people whenever I can that the PIN is easily defeated by a wiley user.  I won't post any links but the info is easy to find.  I just hate to see people put 100% faith in the PIN to secure the phone.  I've tried the PIN defeat on Android and iPhone and it works.

@IT-Monkey-Dave - No harm in pointing that out.  It is good for all to know.  I am sure the security is not infallible but the point about it as far as Activesync is concerned is that without it - you cannot remote-wipe the phone.

Hopefully no-one puts all their faith in the PIN - they will ideally guard the phone with their lives!  In the 20 odd years I have owned mobile phones, I have never lost or had a phone stolen - but then I may be a rare breed!
