I have seen several post indicating they purchased phone/calling cards for their SR. I wasn't expecting any calls from our son until a week or two before graduation. I was happily surprised when he did call on Saturday, almost 2wks into BC. Should I send him a calling card? Can he purchase his own,or use his debit card? What are their options if they don't have a calling card. Once he gets to "A" school he would have access to his cell phone?
