roaming question

I’m on Sprint free incoming 300 plan, which has the roaming add-on option. If I’m in an area where there’s no sprint service and switch to another carrier will my incoming calls still be free?

Well, as I understand it, you won’t be charged for the roaming, but you’ll be charged for the incoming minutes, unless the calls are in an offpeak time. Actually the incoming minutes will be deducted from your anytime minutes
