You’ll see a charge indicator on the screen. Plug it into the wall socket and charge it fully before switching it on. Be careful not to push out the smaller SIM, it can cause damage to your Pocket WiFi if you attempt to use it. Note: All pocket WiFi models take a full-size SIM (the larger SIM you can push out).

Insert the SIM (1), then insert the battery (2) and replace the back cover (3). You’ll see the WiFi Key and SSID engraved on the back of the device. You'll find the details on a label underneath the battery. Make note of the Wi-Fi details (these are case-sensitive): Push the release button on the back to unclip the back cover. Use your fingernail to unclip the back cover from the bottom corner.
