A blooming sleepless night

This Mini Modem arrived in the mail and looked easy to fix but alas, not quite so simple for an old girl. I turned things any way and still it would not fit. First how to open the jolly thing, Bingo I got that. Next how to install SIM card!!!, had to ask for help. Finally got the battery in and am now charging so will know later what the next step is. Why oh why do I love those Gismos? IF i get it all working, my Ipad should then be connected anywhere I go.
