Information for Customers Affected by Planned Rotating Power Outages in California

August 18, 2020

The California Independent System Operator issued an advisory that due to high temperatures across California, planned rotating power outages are possible over the next two days.

Today, the California Independent System Operator (ISO) advised that because of high heat and limited energy supplies, power providers across the state should be prepared to implement rotating power outages through Thursday, August 20.

T-Mobile is monitoring the situation and staying in close contact with the power providers. Rotating outages are implemented to help prevent more widespread and serious loss of power.

Our priority is to keep our customers connected. In the event of rotating power outages in the next two days, it is possible that there may be intermittent impact on our service.

We encourage customers to take a few quick steps to prepare in advance of likely rotating outages:

  • Follow PG&E and SCE on social media to stay up to date on the situation:
    PG&E Twitter 
    SCE Twitter
  • Fully charge all your devices. Consider investing in a charging device like an external battery that doesn’t need a power outlet – and fully charge it as well.
  • In the event the T-Mobile network is unavailable and power is available to you at home, set up Wi-Fi Calling on your phone. For Apple phones, go to Settings > Phone > Wi-Fi Calling; and for Android phones, go to Settings > More Connection Settings > Wi-Fi Calling.

When you first enable Wi-Fi Calling on T-Mobile, you must provide us with the primary street address at which the Wi-Fi Calling service will be used (“Your E911 Registered Address”). If you call 911 over Wi-Fi we may transmit Your E911 Registered Address to the 911 Communications Center, who may use it to help emergency responders locate you, but you may need to provide your contact information and current location. You’ll need to update Your E911 Registered Address if you plan on using Wi-Fi Calling service at a location different from Your E911 Registered Address. You can update Your E911 Registered Address by accessing your account or by contacting T-Mobile Customer Care.
