Just a word of caution, I purchased the $150 mobile starter kit about a month ago. Tried to activate it, was unsuccessful. Turns out the number allocated is somehow already allocated to another customer. Anyway, so I've been trying to contact Boost. Long story short calling the support number takes you in a loop, tells you to go speak to someone on live chat. When you visit their "live chat" section there is a message "Due to increased quarantine measures, there is currently a longer wait time with our Customer Care and Live Chat is currently unavailable."
I guess you get what you pay for and I am shrugging this loss off.
Seems like your sim pack has expired
