To confirm your contact information, go to your Xfinity Mobile account and click Service Settings > Edit Contact Information. If you notice that your emails aren't showing up on your phone, there are a couple of things you can check: Confirm that you've added the correct email address to your iPhone, Samsung, or LG phone. Check that you are connected to WiFi. If not, please confirm that your phone shows a 4G LTE or 3G network signal.
