Hi there! I'm here to help you with the issue you're facing with the Independent Financial mobile app not sending a security code to your phone. Let's see if we can get this sorted out.

First, could you let me know if you have any specific error messages when trying to receive the code? Additionally, please confirm if your phone has a good signal and can send and receive SMS messages normally.

Sometimes, there can be a simple fix. For instance:

1. Check Your Phone Number: Make sure the phone number linked to your Independent Financial account is correct. If it's not, update it in your account settings.

2. Network Settings: Ensure that your iPhone is connected to a reliable network and you're able to receive SMS from other senders.

3. Restart Your Device: Restarting your phone can sometimes resolve SMS issues. Have you tried turning your iPhone off and back on again?

4. Carrier Restrictions: Occasionally, phone carriers may block certain messages. It might be worth checking with your mobile carrier to ensure that your phone isn't set up in a way that prevents receiving texts from the bank.

If you’ve already tried these steps and are still having trouble, we can explore a bit deeper or consider reaching out to customer support directly. They can assist you in checking whether there might be a server issue or if there's something specific with your account.

Please let me know how you'd like to proceed!
