The 2G to 4G cellular upgrade experience on SS3

Huh. I have SS2 systems and put in the LTE/4G cell modems long ago. But, for some reason, I was under the impression SS3 always had LTE/4G capability. Guess not?

"Most Original SimpliSafe and Gen 3 SimpliSafe systems sold before December 2019 contain cellular modules that rely on 2G cellular signals to communicate."

I just received the Upgrade E-mail yesterday and placed my order.  I upgraded from SS2 to SS3 when it first became available a few years ago and was under the assumption it was operating with 3G for Cell service.  Thanks for posting this Thread with the explanation and video, and thanks to SS for the free upgrade.

I did the 4g upgrade and have had issues with the system uninstalling itself now. I’ve had this system for years and never had any problems and then had to do the upgrade and within the last 2 months it’s been a headache because when it uninstalls  it deletes everything.  I don’t have a lot of free time to call support for these problems.
