Sim card PCB signal routing on top and 4.0v voltage regulator recommendable?

Hello friends, I am designing a PCB routing, in the top layer I place the sim card socket and in the bottom layer the 3.8v regulator, can this cause me interference problems?

Best regards

It is recommended that the SIM_DATA&SIM_CLK signals be kept away from the power supply as much as possible. The SIM_CLK signal is recommended to be handled with GND.
