There must be better options for data only for a mifi device than Mobile Share.
You are correct. I missed that fact about it being the only device.
Since the OP is wanting to have only the mobile hotspot device, and not have it on all the time, they may want to consider going with a pre-paid service option. This would allow them to pay for data and turn it on for a month and then not use it for a few months, and pay again to turn it back on. This may be a slightly better fot for what the OP wants.
