OK I drive a 2015 MS have mcu1 will I need to take out the mcu1 console to change sim ?

Or is it as simple as take the cover off underneath the mcu1 and just swap

Here are two videos if it will be the latter taking mcu1 apart il just pay tesla to do it

Upgrading from the 3G radio to LTE requires taking the MCU out and replacing the daughter card as shown in the first video. It's not just replacing the SIM card. But you should just upgrade to MCU2 which includes the LTE upgrade. MCU2 is night and day better compared to MCU1.
