We have the Verizon MiFi 3G card. It costs $35/ month for 3GB plus $10 per GB when you go over. It can be suspended when not traveling. One drawback is at Rallies or parks when there are many people with Verizon. The problem is too many users on the same cell tower. The speed of downloads really slows down. I have a friend with a 4G card and he is not happy with the speed. I have talked to Verizon and they offer no help. You don't want to download a movie on an Ipad. It cost $20 in over charges due to 1.5 GB size of movie. Good luck
