Hi! I see you're having trouble receiving the one-time code (OTP) from the Pocket FM app on your iPhone running iOS 18.6.2. Let’s work together to get this sorted out.

First, just to clarify a bit—when you say it says the code is sent but you don't receive it, do you mean you don't get any SMS message, or is it supposed to come via email or an app notification? Also, are you currently connected to a strong internet or cellular network?

Meanwhile, here are some steps we can try:

1. Check Signal and Network: Ensure your iPhone has a good cellular signal or Wi-Fi connection. An unstable or weak connection might block OTP delivery.

2. Verify Phone Number: Double-check that you've entered the correct mobile number in the Pocket FM app.

3. Restart Your iPhone: Sometimes, simply restarting your device refreshes network settings and can help receive new messages.

4. Check Message Filtering: On iPhone, sometimes SMS from unknown numbers may be filtered. Open the Messages app, tap ‘Filters’ at the top left, and check Messages from Unknown Senders.

5. Disable Do Not Disturb: Ensure Do Not Disturb or any Focus mode is not blocking notifications or messages.

6. Update Pocket FM App: Go to the App Store and make sure you have the latest version of Pocket FM installed.

7. Reinstall the App: If updates don't help, uninstall and then reinstall Pocket FM. This can fix app-related glitches.

8. Try Receiving the Code on Another SIM or Number: If you have another number, try sending OTP there to isolate the issue.

If all this fails, there might be a delay or issue from the Pocket FM servers or SMS provider side. In that case, contacting Pocket FM support at [email protected] could help resolve backend issues.

Could you let me know which of these you've already tried? That way, I can guide you better. Also, confirm if you receive other SMS messages normally on your phone.
