| [title] Solder new socket | |
| - | [* black] You can optionally add solder to the pins before installing the new SIM socket. The 8 small signal pins must have an especially good connection. |
| - | [* red] The socket will have 8 signal pins on the card-inserting side, several pads for shielding, and two pads at the rear for inserted SIM detection. (Red circle in all images indicates the location) |
| - | [* green] Place the new socket on the board and solder at one shield edge first to make the socket more stable. |
| - | [* black] Solder the eight signal pins at PCB board edge. Try to be as steady as you can when soldering. If you happen to bridge some pins, do not panic. Use a solder wick to remove additional solder. |
| - | [* black] Use a magnifying glass or microscope if necessary. The contact area of the signal pads is tiny, so even if they look like they are touching the PCB board, they might not actually be touching. |

| [* icon_caution] Before soldering all shield pads, check if system is working! Otherwise you might have to re-solder the socket again. | |

| + | [* icon_note] You can test the device while it is open, but the PCB board and the battery have to be in place. You will be able to see if 3G works but WIFI may not work because the antenna is on the back cover that is removed. |
