Text from 91639 that WiFi Isn't Reaching All Devices
Received the following text from short code 91639:
Hi, it's AT&T. Looks like your Wi-Fi signal isn't quite reaching all the devices in your home. Go to https://my.att.com/t/zPNPp6OmsKe7Iqq to find the weak spots.
Text STOP to opt out of receiving updates about your services. Espanol? Envie SP.
I checked the Smart Home Manager and there are no issues. Will someone will someone please confirm that this is a valid text or a scam?
