Three LBR20's, yes, 3 different SIM cards, all purchased separately after the device (Verizon doesn't sell this router on their own website, so has to be ordered from Netgear or elsewhere.)
The reason for three routers is Verizon's inexcusable choice to have a 15 GB per line/device high speed data limit, no matter what plan you have, unless you open a different account for each device to get higher limits, at much higher total cost. We both work from home with data-intensive employer systems, so 15 GB is sometimes not enough for even one of us for a month. Our distance from the nearest cell tower means we need a directional antenna for each router, and at least at the time the LBR20 was the only high speed router/hotspot with external antenna SMA cable inputs that was also (originally, supposedly) compatible with Verizon cell service.
The one obtained early 2020 right after LBR20 finally became available works with Verizon fine, no hiccups. The two added in December 2020 could never be added, and eventually Verizon cust service said it wasn't an approved device per their IT department, as I recall. A request to get it approved since one was already being used (!!!) got no response from IT, apparently, because I never heard back and couldn't get someone on the line to answer the question later. Pandemic-induced staffing issues or whatever else has made this worse, I'm sure.
However, the "not an approved device for Verizon" is something definitely stated by Verizon service rep after they tried to get the latest routers activated.
