That has got to be the dumbest design and seems more designed to compel you to pay the subscription. Well that is not happening, at least not at a ridiculous $120 for such a simple service. I would at something like $40/yr. I saw a company selling a multi-year IoT SIM for $60 with about 20MB/month so I couldn’t believe what you want to charge. You are essentially selling a niche service for about half of my annual cell phone bill where I get MUCH more with calls, texts and 15GB/month. /end rant
