I don't have one of these devices yet. I am trying to ascertain if it does or does not provide Reverse 911 and WEA support, like a direct wireless connection does, prior to pursuing purchase. I have already read the FAQs page. Apparently this question is not asked frequently because it isn't answered there.
Maybe you need to try to learn about and understand Reverse 911 and WEA, and how VZW provides these services to mobile phone, connected via the real wireless network, in affected areas, before replying again. Question is if VZW provides these services to phones connected via this network extender in affected areas.
