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.

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.
