A:AnswerThis is a great question, Dusty05.
WiFi calling is dependent on your carrier. I recommend that you speak with Sprint if you want the device to be able to be WiFI calling accessible. I hope this was helpful and have a great day.
A:AnswerYes this phone does have a 1 year limited warranty. However it only covers manufacturing defects. If you purchase additional coverages those will be an add-on fee.
A:AnswerIt's not an older version. The 935f is the international version still being sold in Europe. While Snapdragon is marginally faster it also heats up more and is not as energy efficient. Yes the935u supports CDMA but is that worth the one to $200 difference? Additionally, the U, which is the North American version, can be placed under warranty while Samsung does not support the international version with the warranty. I still feel like I must be missing something?
A:AnswerAbsolutely; right now it has a movistar sim in it, without any issues.
(Definitivamente; lo estoy usando con un SIM de MOVISTAR, sin ningun problema).
A:AnswerThere are multiple security options for this device.. I personally use the fingerprint and patterns option. I'm not sure if that's what you're asking however.
A:AnswerThe unlocked version will, but check the LTE bands to see if they are supported there. Calls and texting would work, but maybe not data on LTE.
