It is incredibly important to Hello Mobile that our customers can contact 911 whenever they need. Therefore, you may make calls to 911 even during the number transfer process.
HOWEVER, the public safety dispatch center might not be able to call you back after you contact them as they could fail to receive a usable phone number from your handset.
For this reason, be sure to immediately explain your emergency and location in detail to the emergency operator after dialing 911.
