Note: SIM_DATA has been pulled up with a 10KΩ resistor to SIM_VDD in module. A 100nF
capacitor on SIM_VDD is used to reduce interference. For more details of AT commands about
SIM, please refer to document [1].SIM_CLK is very important signal, the rise time and fall time
of SIM_CLK should be less than 40ns, otherwise the SIM card might not be initialized correctly.
If SIM_DET is used, a 10KΩ resistor is necessary to pulling up to the power VDD_EXT.
