Checking out Hologram’s Developer SIM Card for Worldwide IoT Projects

Hologram is a service that offers 2G/3G/4G cellular connectivity for the Internet of Things via a SIM card that works in over 170 countries, and with pricing starting at $0.40 per month. In order to promote their services, the company offers a free developer SIM card which I ordered when I first wrote about the service last month. I was pleased and surprised they would sent it to Asia for free, and I got the card in a bubble envelop. The back of the card includes a 18 to 22 digit SIM card number and bar code, that we’ll need to use for activation, and a link that redirects to https://hologram.io/docs/. I planned to try the card with Wio GPS tracker board which requires a nano SIM card, and there are convenient cutouts to convert the SIM card to micro SIM or nano SIM card formats. Before using the card […]

The Future of Cellular IoT Explained – LTE M1, LTE NB-IoT, eSIM, and Battery Life Hype

Telecom companies also want their share of the IoT business, but with 2G to 4G cellular technology often being too power hungry and/or expensive for this market, 2G on-going – or upcoming – sunset depending on your location, LTE Cat M1 and LTE Cat NB1 (aka NB-IoT) standards have been developed, and used in products like Pycom FiPy board, and SARA-R4 and SARA-M2 modules. If you want to have an overview learn about the new LTE IoT standards and the future of cellular IoT, Particle has published a useful presentation – embedded below – dealing with both, as well as eSIM (Embedded SIM), 2G sunset, and battery life expectations. The main takeaways from my reading of the presentation: LTE NB1 is better suited for low power stationary sensors transmitting a small amount of data a few times a day. Requires new hardware and software LTE M1 can be used for […]
