MKR GSM 1400 and SD card module

Hi,
is it possible to connect MKR GSM 1400 (Arduino MKR GSM 1400 — Arduino Official Store)

to

MicroSD module:

... directly or should I use step up/down convertor 5V/3.3V (e.g: https://www.sparkfun.com/products/12009)?

Does the information in the description of that product suggest an additional level converter is needed ?

However I can see the confusion.

SD cards do use 3.3V, and foir 3.3V systems you connct them direct no adapter boartd is actually needed.

Converter boards, with regulators on them, are for using the 3.3V SD cards on 5V systems.
