Hi there! I understand you're having trouble entering your payment information with UPS. Let’s work through this together.

Could you provide a bit more detail about the issue? For instance:
- Are you receiving any specific error messages during the process?
- Is this happening on the UPS website or through a mobile app?
- Have you already tried any troubleshooting steps?

This information will help me assist you more effectively!

Mobile app and says experiencing technical difficulties

Thank you for that information! The message about "experiencing technical difficulties" usually indicates that there might be a temporary issue with the UPS mobile app or the server on their side.

Let's try a few steps to see if we can resolve this issue:

1. Check for App Updates: Ensure your UPS app is updated to the latest version. Go to the App Store, search for UPS, and check if there's an option to update.

2. Restart the App: Close the UPS app completely and then reopen it. Sometimes, restarting it can fix temporary glitches.

3. Check Your Internet Connection: Ensure you have a stable internet connection. You can switch between Wi-Fi and cellular data to test if the issue persists across both.

4. Clear the App Cache (if possible): Go to your iPhone Settings > General > iPhone Storage. Look for the UPS app and tap on it. If you have the option to offload the app, do that, then reinstall it from the App Store.

5. Check UPS Service Alerts: Sometimes, there could be server issues from UPS's side. You can check their service status at this link: UPS Service Alerts.

If the issue persists after trying these steps, it might be a temporary issue with the UPS servers. In that case, waiting a little while and trying again later could be the best option. Additionally, you can check sites like Downdetector to see if there are any reported outages.

Are you able to try these steps, or is there anything else specific you'd like further assistance with?
