That's half a dollar of data. Now I understand that IOT stuff would likely have smaller payloads. But that really looks like a great way to rack up costs with a run away program submitting or retrieving data in a bad loop.
For datagram-based protocols like CoAP which are explicitly designed to let you control bandwidth usage down to the packet level this should be fine. 1kB of data (which is honestly large for a normal telemetry or sensor payload) is really cheap, even at $0.10 per MB.
Many of the devices and network architectures in this space are made to literally wake up a few times a day and push/pull data, not keep idle connections up and running. Your "runaway loop" would kill the device's battery and cause a bunch of other red flags in such a topology long before it racked up substantial bandwidth charges.
If this really is the pricing, then it's definitely IOT focused instead of Programmable Wireless's more general focus.
The “starts at” that we have on our pricing page is for the cheapest priced networks we have in each country. For example, in the UK we have a number of networks that are $0.10 per MB but if you want to use EE it’s $0.20 per MB. With our Network Access Profiles, you can pick exactly which networks you want your Super SIMs to be able to connect to. If EE is the only network that services your area or works best with your hardware and is worth premium to use, you can enable it for your Super SIMs.
For now, we just have a pay-as-you-go pricing plan for Super SIM whereas Programmable Wireless has a number of different quota plans that let you commit to a minimum monthly spend per SIM in exchange for discounts as a way for you to self service into lower data costs for hungrier devices. Our pay-as-you-go prices are meant to just get you started. We don’t expect any of our developers to scale up their IoT business at these list prices. Once you’re up and running, you can connect with one of our IoT sales specialists to discuss volume discounts. Promise they don’t bite!
