Hello. I am new to the entire sim card thing. Ive been with Verizon for over 10 years and I never had a sim card before the iPhone 5 and the Mifi device my friend gave me. Plan: Mifi is month to month. I have the share everything plan. My iphone 5 hotspot is active at no extra cost with this plan. I cant use the iphone as hotspot as I want hotspot to stay home. My question: Am I able to take the sim card out of my Verizon mifi (that I pay $20 a month for) and put it in my ipad? Will Verizon then just charge me $10 a month? Could i then switch the sim card back to the mifi whenever and pay $20? Also will the ipad hotspot feature be active like the iphone 5? And is the ipad a good device to use as a hotspot? I just dont know why I should keep using the mifi if I could just get an ipad and use that. Thanks for all the help and info you can provide.
