"When you purchase the card you will receive an email which will get you a PIN. Call the Verizon number 888-294-6804 and follow the prompts."
you will need the card PIN #
your account number
the device ph#
have them in front of you before you make the call
the acct # and ph# were on the paper work you got with the mi-fi
i think the ph# is the account #
mine is expired and i have to get it re-activated thru somebody or buy another one
do not let it expire, better to spend an extra $5, by being early than to wait and be late
