I used 3 different unlocked phones in US, as for US sim cards, I used MetroPCS, T-mobile, and Cricket, non of those added anything, althought their respective websites told me about an app they strongly reccomended. Only trace was the Sim card toolkit menu which was diaplayed for whatever inserted sim card, but I never used any of those.

Depending on the device you are using you might not have noticed. I used WireShark on a hotspot that my unlocked IPhone was using and captured the visual voicemail blob used by Cricket/AT&T just last week. Also, the SIM card toolkit can be used remotely by your provider. Lookup SimBad exploit
