The carriers able to offer additional data are indeed a major help for those without home WiFi. I'm especially thankful that some carriers have thought specifically about those with family members overseas in affected areas, and made their lives a little less stressful by being able to stay in touch.
i can confirm the Verizon 15gb. i have a prepay $40 with normally 3GB. they are allowing it to hotspot. however after April 30th ( unless they extend it) it doesnt roll over if you dont use it and it goes back to your monthly allotment
