As the full speed wired service where I am is not 100% reliable I use LTE data on a second router for my backup access on my home office network for web conferences and webinars.
At the present time I buy in bundle of 20 SIM that gives me 8Gb of data for 30days with face value (full retail) at $78 at deep discount. To refill for a second 8Gb/30days would be more than twice my cost of one SIM. I just toss them when the data is used up.
Gotcha! That makes perfect sense. It does seem inconvenient though.
