We have reached another milestone in our mission to make cellular IoT available to anyone, including private persons. The most heard feedback on the Walter project is about how one can buy a SIM card that actually supports modern NB-IoT or LTE-M connectivity. Especially for private persons these SIM cards were unobtanium if you are not a business. 

Together with Soracom we have been working hard on our online order portal. You can order Soracom global SIM cards in single quantity units with excellent roaming agreements and power consumption. Check it out on
