^ ^ This works in slow, quiet places. They want you to call the non-emergency line and ask if they are busy and can you can do a 911 check call.
That works, or ask friends for old phones. I havent bought one in several years, most people buy the latest greatest, I just want a basic functioning phone. Many people are happy to give you their 1 or 2 year old phones. Some can get downright insistent when they see you with an antique phone.
