Samsung Galaxy Note 4 - Virtual Private Networks (Vpns)

CanIDisableMobileData?
Ifyoudisablemobiledata,youcansaveonbatterylife;however,youeffectivelykillthe
functionalityofanyappthatneedstobeconnectedallthetime,suchasinstantmessagingapps
(Yahoo!orGoogleTalk)orappssuchasSkype.Youalsostopreceivingemailinrealtime.When
thisfeatureisdisabled,about5minutesafteryourGalaxyNote4goestosleep,itdisconnects
fromthemobiledatanetwork;however,itremainsconnectedtothemobilevoicenetwork.
>>>GoFurther:WhySelectOperatorsManually?
Whenyouareroaminginyourhomecountry,yourGalaxyNote4automaticallyselectsyour
homecellularprovider.Whenyouareroamingoutsideyourhomecountry,yourGalaxyNote4
registersonacellularproviderbasedonitsnameandhowitscoresalphabetically.Thelowest
scorealwayswins.Forexample,acarrierwhosenamestartswithanumberisalwayschosen
overcarrierswhosenamesstartwithletters.AcarrierwhosenamestartswiththeletterAis
chosenoveracarrierwhosenamestartswiththeletterB,andsoon.Asyouroam,yourhome
carriermightnothaveagoodroamingrelationshipwithacarrierthatyourGalaxyNote4has
chosenbasedonitsname,soit’sbetterforyoutochoosethecarriermanuallytoensurethebest
roamingratesand,manytimes,basicconnectivity.Youwillnoticethatsometimescarriersare
representednotbytheirnamesbutbytheiroperatorcodes(orPublicLandMobileNetwork
[PLMN]number).Forexample,53024isactually2DegreesinNewZealand,and53005is
TelecomNewZealand.
>>>GoFurther:BoostYourDownloadSpeeds
YourGalaxyNote4hasafeaturecalledDownloadBooster.Whenyouenableit,itallowsyour
GalaxyNote4todownloadcontentoverboththecellulardataandWi-Finetworksatthesame
time.Becausethedownloadsaretransferringoverbothnetworks,thetimeittakestodownload
contentisfaster,sometimesdoublethespeedofjustWi-Fi,dependingoncircumstances.Of
course,ifyouhavealimitedcellulardataplan,youmightwanttobecautioususingthisfeature,
orkeepitdisabled.ToenableDownloadBooster,pulldowntheNotificationbarandswipefrom
lefttorightacrosstheQuickSettingsiconstoseemoreicons.TaptheDownloadBoostericon
andmakesureitturnsgreen.
