SIMs are usually robust and seldom the cause of issues.
There can be some hardware/ software issues on your SIMs in rare cases, so here’s the basic troubleshooting steps:
Check if your device can recognize the SIM/eSIM. Do you see a notification indicating there is no SIM inserted?
Can you read the ICCID/ IMSI of the SIM/eSIM?
Check if the SIM/eSIM works in a different device
Is there an error message that shows up from the SIM?
If a hardware issue is detected in a one-off SIM, it may be just damaged. Replacing the SIM with another should resolve the issue.
In case there is a consistent hardware issue across a batch of SIMs or some errors are seen, please reach out to us - we may ask you to ship some SIMs to us for further investigation.
