Frequently asked questions.
With Onomondo you can enjoy the flexibility of no active SIM fees (aka fees for SIMs that aren’t sending data). Instead, you only pay for data in the months that your SIM sends data and generates value for your business.
Onomondo SIMs are delivered activated. We don’t charge fees for SIM activation and have PAYG data subscriptions. You just need to set the APN to “onomondo” and make sure data on roaming networks is enabled on your device (if required) to start using an Onomondo SIM.
We have private static IPs. Onomondo has one global network profile, so when we say the IP address is fixed, it does not change, no matter which RAN the device is attaching to around the world.
With Onomondo, you can see everything from SIM to cloud thanks to our full core integration in over 180 countries.
