Please don t try to buy a SIM card here unless you re signing a contract for at least two years. They only sell their in-house brand (starts at $20 USD for 1.5 GB) and they ll ask you to confirm that a) they won t help you set it up (this includes even opening the SIM card slot on your phone with a pin) and b) they bear no responsibility if you encounter any problems with the installation.

If you re buying electronic devices, especially if you speak Mandarin, you re fine. Otherwise...
