Galaxy S4 Sim card

view story

http://forums.androidcentral.com – I have a question. I have the Galaxy S2 SGH-S959G that is Straight Talk / Tracfone Branded that was released by Straight talk, but honestly i hate it because it is still using gingerbread and have no plans on updating it for that phone and I want to get a Unlocked S4 and port it over to straight talk. Now my question is, can i use the sim card from the S2 in the S4? - Is it the same type of card? And also will straight talk let you do that or do you have to buy a new card? I plan on getting a S4 in the next week or so and need to know if I need to order a new sim card from them or if (HowTos)
