Hi ​@TLM2703,

Thanks for getting in touch.

If incoming calls only go straight to voicemail when you're at home, it could be related to the signal or Wi-Fi Calling rather than your SIM.

We'd recommend trying the following:

• Turn Wi-Fi Calling off, then back on again.
• Turn Airplane Mode on for 30 seconds, then switch it off.
• Perform a network settings reset on your phone.
• If your phone allows it, change your preferred network mode to 4G only and test your calls.
• Check our coverage checker to see if there are any issues affecting your home postcode, you can check it here: https://www.idmobile.co.uk/help-and-support/coverage

If the issue continues, please contact our Customer Service team via Live Chat so they can investigate further and, if needed, raise a technical ticket with our network team.

Regards,
