I am thinking about getting the new Galaxy Note phone, but I want to put it on Virgin Mobile (US). Is this possible? If not does anyone know of any phone service like Virgin Mobile I can put the Galaxy Note on?
No, this isn't possible. The Galaxy Note is a GSM phone whereas Virgin Mobile USA is a CDMA network (it is a subsidiary of Sprint). The two are not compatible. In addition to this, CDMA carriers typically only activate phones that are specifically branded for their networks, so you can't even use a Sprint phone on Virgin unless you "know a guy" or find a really nice rep.
The Galaxy Note is quad-band GSM/UMTS, supporting the 850/900/1800/1900 MHz GSM bands and 850/900/1900/2100 MHz UMTS (3G) bands. If you get one that is not carrier locked then you can use it on AT&T, T-Mobile, and any smaller US carrier that uses their spectrum (Straight Talk, for example).
me thinks it can be done because a Virgin Mobile phone rep told me that I could use a Verizon Note 3(Verizon 4G LTE phones are unlocked) but wouldn't you just know when I got the Note 3 and went to activate on Virgin Mobile I was shot down!
AND I have a friend that has an old sim from Virgin Mobile and when she put that sim in the Verizon Note 3? In the settings of the phone(Apps > Settings > GENERAL > About phone > Status), it showed her phone number
