Hi ​@TraceyM,

Thanks for your post.

As the SIM is being used in a NETGEAR Nighthawk router, we're quite limited in the troubleshooting we can provide, as iD Mobile SIMs are designed for use in mobile phones rather than third-party router devices.

To help narrow down the cause, we'd recommend:

• Removing the SIM from the router and inserting it into an unlocked mobile phone.
• Checking whether calls, texts and mobile data work on the phone.
• If the SIM works correctly in the phone, try using the phone as a mobile hotspot as a temporary workaround.

If the SIM doesn't work in the phone either, then the issue may be related to the SIM or account rather than the router itself.

As the APN is already set to 3internet, and the router is reporting a subscription/APN-related error, testing the SIM in a handset is the best next step to determine whether the issue lies with the device or the service.

If the issue persists when the SIM is in a phone, please contact our Customer Service Team via Live Chat for further assistance: https://www.idmobile.co.uk/live-chat

We hope this helps point you in the right direction.
