Since no less than December and presumably a lot earlier, My Cell Account has been displaying this data for each buyer account at any time when it’s introduced with a sound Q Hyperlink Wi-fi telephone quantity. That’s proper—no password or the rest required.

Suggestions left in opinions for each the iOS and Android choices additionally reported this situation, in a number of instances with a response from a Q Hyperlink Wi-fi consultant thanking the individual for the suggestions.
