Certification & SIM Cards

by Daan P

We have fantastic news to share: we have completed the certification process for Walter! All tests are a full pass, and our team is now preparing the submission documents. This confirms Walter’s design is sound and the CE, FCC, UKCA, IC, and RCM markings are well deserved.

At least as exciting as passing all certifications is our participation at Embedded World 2024 in Nuremberg. You can visit our booth in the M2M area in Hall Three, booth 3-610. We have prepared a cool weather-station demo with Walter Feels. Our team would love to hear what you will build with Walter, so come have a chat with us if you find yourself in Nuremberg!

Finally, we can now reveal that we are ready to offer Soracom SIM cards for individuals anywhere in the world. Based on feedback from our backers, we are setting up a web shop where you will be able to order Soracom SIM cards for your Walter modules. More on that in a future update.

Meanwhile, keep telling your friends about Walter and helping us spread the love for cellular IoT!
