I just updated the letter I posted a few months ago in case anyone cares t o use it.
Dear (customer )
As we all experience now days, old technology is constantly being replaced with new, Seems like we just get used to our new cell phones, laptop or Ipa d and a new one is being advertised.
Likewise, in the alarm business, we are also subject to the advances that t he cell phone providers make with their technologies.
You presently have a cellular radio installed at your home/business using T hird Generation (3G)cellular technology that is being replaced with Forth G eneration (4G) cellular technology. As evidenced by the history of their pa st performance, the cellular service for your device will become less and l ess available as they transition to the newer 4G technology. At some point around the end of 2020, the 3G service will no longer be maintained and you r alarm system will no longer be able to communicate with central station.
I will be contacting you over the next couple of months to make an appointm ent to change your system over to the new 4G cellular service.
As always, thank you for your business and loyalty through the years. It's been a pleasure serving you.
Please call if you have any questions.
