If you have an iPhone you can have it become a "hotspot" to drive up to 5 other devices including computers. Costs an extra $20 per month to do so. You turn the feature on when when you anticipate needing it and turn it off when you don't. They pro rate the $20 based on days use.
While in the hotspot mode one can also tether their iPhone directly to a computer for internet access.
I used to use a Verizon air card (469 per month) but picked up an iPhone and pay less $$ per month when I use it as a hotspot...which is anytime we are away from TV.
