I moved your question to its own topic. Even though it’s related to this transitional wait-and-see state we’re in, it’s pretty specific to your situation, so I don’t want us filling up the inboxes of everyone “following” the topic.
The beauty of Community is that no one here has to depend on me. If I’m not around, there’s a whole “Community” of friendly people able to help you.
To answer all three questions in very general terms, we’re still shipping SIM cards for people who need them, and, as of my writing, we can still activate on the My Choice plan. I’m glad @rolandh is working with you to help you determine if the SIM card you have can be moved to a different phone.
Roland is working through helping you figure out if your SIM card is GSM or CDMA. Even though it’s a “Republic Wireless” SIM card, it was designed for use on either our GSM partner’s network (T-Mobile) or our CDMA partner’s network (Sprint). Only the GSM SIM cards can be moved from one My Choice compatible phone to another My Choice compatible phone.
With your permission, I can look at your account and tell you in this public forum what kind of SIM card it is, assuming your wife’s phone is on your account. That would save you from squinting at the card and trying to figure out the color scheme.
