I have Verizon Fios and Internet at my home and a Verizon email account. I do not have a Verizon wireless phone. My Android smart phone from Republic Wireless will not send emails that have attachments, over my Verizon WiFi. I can turn the WiFi off on my phone and the phone will send the messages over Cell service to my Verizon email account. My Verizon router is a standard setup with standard settings. I have not verified whether my emails can be sent on other WiFi locations outside my home, but I'm fairly certain that they will not send on other WiFi either. Is there a special permission or setting I need from Verizon to be able to use a Non-Verizon cell phone on WiFi?
