Update: The Galaxy S9+ unlocked has a network connectivity issue. It seems that it's better getting the device from the carrier. But unfortunately Boost doesn't offer the phone.. Now maybe an upcoming software update will fix the issue, since Samsung has acknowledged that the S9+ unlocked variants has issues.
@trillzoe60@IrossdrummerI don't understand. I bought my S9+ directly from Samsung, the sim card from best buy & was able to activate the phone without having to call tech support or even go online. It works just fine even though in occasions I noticed a lost on signal strength but I attribute that to the boostmobile network itself not the phone. In short, get the phone directly from Samsung (they even have a descent trade in program), get the sim directly from boostmobile or best buy, activate the phone (existing boostmobile customer). Those of you coming from a different network might have to go thru https://activate.boostmobile.com/bring-your-phone to complete the process.
