    1. I have a new ipad6 that I migrated to from my old ipad 2. I tried all three of these steps, but neither this nor the safari will connect without wifi. I toggled them all off and back on, and I checked and I have a Verizon cellular and it shows 3G signal. My mail even shows the time of last update changing, but none of the mail that I know has been sent and I can see on my computer, are making it through unless I find a wifi signal. I appreciate any help you can share, as I cannot get my icloud or work email without.
