A. 1. Double-check that you have completed all steps in the activation process, including any confirmation emails or links that need to be clicked. 2. Verify that the SIM card is properly inserted into your device and that the device is compatible with the SIM card. 3. Restart your device to refresh the network connection. 4. If the SIM card is still not activated, check the status of your order in your account settings or contact support through the available channels for further assistance.

B. 1. If you have access to another device, try inserting the SIM card into that device to see if it activates there. 2. Ensure that your device is not locked to a different carrier, as this can prevent activation.
