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 […]

Hologram LTE Software-Defined Global Network for Cellular IoT Projects Starts at $0.40 per Month per Device

Cellular connectivity can be rather expensive, and in the IoT realms, new LTE standards are still evolving and you may want to manage your own mini cellular network, so ideally we would need a provider that offers both low cost and flexibility. Hologram LTE network does both as it’s a software-defined network, and pricing starts at $5 for the SIM card and $0.40 per month per device. The company also just announced that their network was available for global deployment with the service available in more than 170 countries via partnerships through over 200 cellular carriers. The SIM card supports automatic roaming and carrier switching, and spacebridge inbound tunnel access allows for secure remote programming and device management. The SIM card specifications are as follows: 2G/GPRS, 3G HSPDA, 4G LTE Read/Write Cycles: Min. 500,000 Operating Temperature: -25°C ~ 85°C Data Retention: Min. 25 years at 25°C Triple-cut for Mini, Micro, […]

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 […]
