I have a Verizon Galaxy S4 which I purchase May 30, 2013. I am going to Hong Kong and Thailand next month and would like to add a sim card that I will purchase in each of these countries, to get both talk and data. My phone is rooted already. I found a post online that mentioned somebody had been able to do this since Verizon Phones 4G phones are unlocked, but I never found anything definitive. I am not sure if this is correct but I am trying to confirm. I went into my phone and found where to actually manually enter an APN. Right now it is set to VZWINTERNET. Would I just replace this with the APN of the carrier I want to use?
Entering Access point name information manually: google "APN for thailand carrier" and then enter it.
