My father uses the laptop card with service from Verizon. He has no complaints about it and uses it very often (he is in real estate). Personally I would trust the service from Verizon a lot more than from Sprint, but thats just from my experience. He gave me an extra card but I just can't justify spending $79 a month for the unlimited plan no matter how well it works. If I were on the road that much it would be worth it though. If you have any questions about it let me know and I can find out from him.
