A:AnswerNo, this particular item only works with the Virgin Mobile service (www.virginmobileusa,com). There is a Sprint version also and maybe other carriers as well.
A:AnswerYes, you can just buy the phone without plan, that is what good about prepaid phones, you buy what you need or none at all. Got 2 phones with wifi use like what you intend.
A:AnswerVM is trying to push the Apple phones, but strong presence of Android phones. This is Android 7.0, latest (not available most phones yet) is Android 8.0.
A:AnswerSo I decided to buy this phone anyway despite someone telling me it did not have a gyroscope. I am glad I did, because it turns out that the Samsung website is correct. It does have a gyroscope built in and it can be used for 360 videos/VR. Whomever answered that it did not apparently did not know what they were talking about.
A:AnswerVery nice phone but I am unable to give you an answer as I haven't tried surfing the web and talking simultaneously.
You may want to try asking the folks at Virgin Mobile.
Good luck !
A:AnswerNot that I have noticed. I use activity trackers to keep notified of missed calls / messages. I believe I saw in settings where you can have it vibrate when you pick it up if there are missed calls / messages.
