I didn’t realize when first replying to you that you had created a topic with this same question. I’ve moved our conversation on the matter from Detailed Supported Phone Features in order to focus the conversation in one place.
I won’t post a target date for the release of this SIM option, because target dates tend to be fluid. As i mentioned before, we are in the final stages of testing. The thing about testing, though, is that the purpose of testing is to look for issues, and if any are found, they delay release dates.
I’m also not comfortable with the presumption that the three phones you’ve named will be supported at launch. Support for BYOP models can sometimes take more time than support for the models we offer in our store. Let me check with our engineers on that and get an answer for you that will help you plan.
Thank you for you patience on this matter. Please know development has been ongoing for a very long time, and our teams are excited that the availability of this new SIM card is imminent.
