The end of dual-SIM in IoT!?

Everybody has experienced Dead Zones and areas with bad reception for certain telecom's networks. As companies are deploying their devices in multiple regions & cities, and more and more IoT devices are finding its way to rural areas, the risk of having bad connectivity is high. That is why many device makers have decided to insert two SIM cards, from different telecoms, to ensure good connectivity whether the device is in a big city or in the middle of nowhere. Unfortunately, this means getting two bills for every device deployed, doubling the costs.

Dual SIM devices have been around for a while. The Benefon Twin phone, introduced in 2000, started the trend. Dual-SIM solutions are mostly used in fleet tracking and industrial cellular modems when it comes to IoT and M2M. However, the solution is not perfect as the device has to have a special type of modem to support two SIMs, has to be big enough to house two SIMs, and if the device runs on battery power it drains faster. These issues, plus the cost and hassle of having two contracts from different telecoms, makes Dual-SIM solutions unattractive for many IoT device makers, yet the need for a reliable connectivity remains.

As eSIM solutions are commercially not rolled out yet and expensive international roaming plans do not get you any better connectivity in the domestic market, there really is not a good option to get reliable cellular connectivity for IoT. Or is there?

1oT provides access to multiple networks in more than 150 countries via a single SIM card. Thanks to good relations with telecoms worldwide, we have been able to load multiple profiles to one SIM and do just that. After inserting the 1oT SIM to your IoT device and setting up the APN, it will connect to the strongest network. If you move the device, the SIM will connect to the new strongest available network. When you use 1oT SIM cards, you can monitor all that and much more via 1oT Terminal, our powerful connectivity management platform.
