If I buy a prepaid card and activated on the iPhone, can I switch the SIM card to another Android phone?
Yes. A good SIM can be used in any phone. You just need to make sure the SIM is the right size (there are 3 sizes) and the "new" phone is not locked to another carrier. If the SIM is wrong size, you can get a new one at a TM store.
