Your camera's IMEI/MEID number is on a sticker inside the camera. However, there may be times you need to check whether it's stored properly in your camera's memory.
There are a couple of situations in which you may not see the IMEI/MEID number when you view the Information for your camera (Menu button > SYS (third) tab > Information)
If you just reset your camera to the default settings, the IMEI/MEID number will disappear. Turn the camera off and back on, then view Information again.
If your GoCam is brand new and you have just put it in Setup mode, you may need to change the Send Mode to Instant and let the camera search for and log in to the network before you can see the IMEI/MEID number.
