Mobile phones operate on a different network than portable routers. XOXO WiFi connects to mobile data networks (3G or higher), while mobile phones connect to cellular voice networks. Since cellular voice networks have been around longer than mobile data networks, their coverage is generally much better, especially in suburban areas.

For this reason, there may be situations where you can establish a cellular connection on your phone, but internet access through the router is limited or, in some cases, unavailable, particularly in suburban or remote locations.
