You own a mobile phone don't you?
You carry the mobile phone with its connection in you pocket 99.9% of the time don't you?
Well you set the phone to act as a wifi hotspot, and connect the tablet via that. Tada... One mobile contract, one sim, and it's kept the cost of the tablet down.
That's assuming you have a mobile which can act as a wifi hotspot - hint, Android phones can.
