Hi Stephanie12345,

Please take a look here.

If you’re still facing issues, please test your SIM in a different phone.

Thanks,

Hi Stephanie12345,

Did you try sending one back to yourself and test your SIM in a different phone?

If you’ve done the above and if calls are working ok, please get in touch here so we can check your account.

Thanks,

Gemma
