The adapter and/or charging cable may be faulty. Swap these components, if available, and attempt charging again.

Bad Charging Port ¶ 

First attempt to clean the port. This can be achieved with a dry, unused toothbrush. Compressed air may also come in handy. See guide for more detailed instructions.

The battery may contain one or more bad cells, and is therefore defunct. Replacing the battery may solve the issue. Remove the back cover to access the device’s battery, remove, and replace. (Refer to repair guide for more detailed instructions.)

Replace Sim Card ¶ 

Power down the device. Remove the back cover of the phone, and remove the battery. Locate the sim card to the top left of where the battery sits. Using a pair of tweezers or a similar tool, gently grab and slide the sim card out. The new sim card should slide in by hand. (Refer to repair guide for more detailed instructions.)
