I just purchased an LTE BlackBerry PlayBook, which includes a SIM card. Can the SIM card (Telus Production Microsim III) be used for other devices, if I no longer want to use the PlayBook?
Yes you can still use the SIM card on other devices. You would need to change the plan on the current SIM from the Tablet Data plan you have to either a phone or data plan. The SIM card would need to remain active before the plan change too.
