Order 17 Samsung tablets, hot spot, and SIM cards

Product Name: Order 17 Samsung tablets, hot spot, and SIM cards
There are 17 total tablets, one with a broken screen. They are otherwise identical & measure 5”x7.75” in the case. All are from a now defunct team-building company. I believe they all have SIM cards either in them or between the case & the tablet (as shown in photo). I do not know what model they order are. There is also one hotspot and a slew of chargers. The SIM cards were purchased in 2016 (I know this because I found the receipt in some business paperwork) and I don't know when the tablets were purchased, but definitely prior to 2016. Could anyone put these to use? Please send a message with any questions... can't promise I will know the answer, but I'll try!.
