We are in the process of setting up devices to measure vibrations of trains. We have 3 calibrated devices that need to be equipped with sim cards with a fixed IP address. The data exchange is very light, KB's. Therefore it does not make sense to use a 5GB data service. This is very expensive, measurements and data communication is foreseen for 10 years. What is the best advice?
Hey
Welcome to the IoT Community!
Thanks for creating this topic. I am happy to help.
If i understand you correctly, you are looking for a Data Only subscription with a fixed IP-address and a small data bundle, right? Or do you need an M2M SIM card for this, for example?
If your device has a cpu on board, you may consider using lorawan. The device may create an envope for every period of vibration and send it out over lorawan. With a big battery, 10 years is possible. I use smaller lorawan seismo devices which report 24 messages per day in addition to shock-envelopes expecting them to do this for 2 years without charging.
