Slide say / Cell Phone

Slide say

When people traveling to foreign countries, they usually get a new sim card which is operates by local telecom Ltd.
People waste their precious time by doing this movement.
Therefore, we design the “Slide say” as a smart phone case.
“Slide say” can provide a convenient way to add a new sim card. At the same time, the old sim card can run as usual.
