Sim card in my note 3
I went to best buy today and got my note 3. When I got home I found there's a sim card already put in the sim card slot. I am puzzled, last time I see this was on my touch pro 2, and I was told by sprint customer service representative that the sim card in my touch pro 2 was actually a gsm sim card for the purpose of international roaming. That makes sense, so I bought that story.
When I look at this sim card in my note 3, I'm wondering what is it used for? Since I believe sprint note 3 uses embedded sim card to store cdma+lte keys I suppose this actual sim card in the slot is not used for that purpose. Could it also be a sim card used for international roaming? Or is it the case that the embedded sim card stores cdma keys and this actual sim card stores lte keys, like verizon phones?
Thanks for any input that could clarify this.
