From pyscard user's guide [1]:
== Selecting the card communication protocol ==
By defaults, the connect() method of the CardConnection object
will try to connect using either the T=0 or T=1 protocol.
To force a connection protocol, you can pass the required
protocol to the connect() method.
This means that a PC/SC ifd handler may automatically choose T=1
as the highest protocol if the card indicates both in its ATR [2].
Since pySim only supports T=0, let's select it explicitly.
