How do I set up a SIM?

All you need to do is set the APN to "onomondo" and sometimes make sure roaming is enabled.

Your SIMs will be sent activated. Make sure the SIM is still activated before putting them into a device and turning it on. You can search for the SIM id on the SIMs page on the Onomondo platform.

Once the device is turned on. The two things to be done are:

  1. Set the APN to "onomondo
  2. Make sure data on roaming networks is enabled (only if required).

If you are having a problem with one of your SIM cards, it's best to test the SIM on a device you know that has worked before. We normally suggest testing it on a mobile phone (remember to update the APN settings to "onomondo").  

You can also use the Connecting with AT Commands to help you check your connection with most cellular modules.
