The billing address is where we mail a paper bill or other correspondence. This address can be a P.O. Box.FYI:
You won’t be able to update the billing address on your account if:
- Your account is less than 30 days old
- Your first payment hasn’t been processed
Place of primary use
Your place of primary use address determines the tax rates for your wireless bill. This must be a physical address and can't be a P.O. Box. The address may be different for each user or device on the account.
When you call 911, it goes over the cellular network whenever possible. If you use Wi-Fi Calling to call 911:
- Your call is routed based on location data from your device and the Wi-Fi® network.
- Your call will disconnect if you lose the Wi-Fi connection.
If we aren’t sure of your location, we’ll send your Enhanced 911 (E911) address to 911 dispatchers. Keep in mind, E911 may not be as reliable as regular 911 service.
Be sure to update the E911 address of your Wi-Fi Calling location, so we can find you quickly. You can change your location info on the same screen where you turned on Wi-Fi Calling.
