Boost is a division of Sprint/Nextel.
yes you can put a boost mobile SIM in because the run off the same network. You could also use ISIM, VIRGIN MOBILE, ect.
Boost mobile sim cards will only work with boost mobile on the nextel network nextel is a iden network standalone that will not roam on gsm networks because nextel is a iden network
Yes, you can because Boost Mobile is locked to the Optus Network.
No other devices will work with Boost as they use an iDEN network and this is not compatible with the GSM networks in the US even though they do use a SIM card. The SIM card does work in them for international roaming though. It will not work either way.
You might can use your Samsung S4 on Boost Mobile. You will have to call Boost Mobile and see.
No, you can't because the Sanyo Incognito is with Boost Mobile and Boost Mobile uses CDMA network. So there. Does that answer your question?
Boost Mobile has a wide variety of HTC phones and accessories.
if the phone is a prepaid phone, no. if it came on a plan, or bought outright, yes
If you buy it directly from Boost Mobile or if its unlocked, then you most likely can.
The answer to that question is Possibly, and No. Half of the Boost Mobile phones use IDEN radios (Integrated Digital Enhanced Network). The phones are easy to identify- they have Direct Connect (the "chirp"). These CAN NOT be used on any service but Boost Mobile, or if unlocked, Nextel (Or Telus in Canada). The other half of the Boost Mobile Phones use CDMA radios (Code Division Multiple Access), and could feasibly be unlocked to be used with Virgin Mobile. Whether Virgin Mobile would choose to allow them on the network is a whole additional answer (doubtful), but the technology technically would work.
Boost mobile has two types of service, CDMA and IDEN. So technically its CDMA and TDMA, they do not have GSM service.
Boost Mobile runs on the Sprint network so it is good quality coverage. However, Boost Mobile is not as widely available as other carriers so it may be slow in certain locations.
