Hi! It sounds like you're having some trouble accessing HCMToGo after changing your SIM card. I’m here to help you figure this out.

First, could you tell me if you're using the same phone number associated with your HCMToGo account after the SIM change? Sometimes, if the phone number has changed, it can cause login issues.

Next, let's try a few things:

1. Check Your Network Connection: Ensure that you have a stable internet connection. Sometimes, connectivity issues can prevent the app from recognizing your login credentials.

2. Double-check Credentials: Please make sure you're entering the right username and password. It's easy to mistype these, especially if you use different credentials for various services.

3. Password Reset: If you're still having trouble, you might want to reset your password. You can do this by clicking on "Forgot Password" on the login screen and following the prompts.

4. App Permissions: Ensure that the app has the necessary permissions on your device, especially after the SIM change. You can check this in your device's settings under "Apps" and then selecting HCMToGo.

If you’ve already tried these steps or if the problem continues, please let me know, and we can explore more advanced options! Are you satisfied with the solutions so far, or do you feel we need to dig deeper?

The phone has the same phone number

Thank you for confirming that the phone number remains the same! Since you’re still having issues with HCMToGo recognizing your name or password, let's try a few additional steps:

1. App Restart and Update: Make sure to restart the HCMToGo app. Sometimes, simply closing and reopening it can resolve minor issues. Also, check if there is an update available for the HCMToGo app in your app store. Keeping the app updated can fix bugs and improve functionality.

2. Clear App Cache: Clearing the app cache can also resolve issues. To do this:
- Go to your device's Settings.
- Tap on Apps.
- Find and select HCMToGo.
- Tap on Storage.
- Then tap Clear Cache.

3. Reinstall the App: If clearing the cache doesn't help, consider uninstalling the HCMToGo app and then reinstalling it. This can often resolve persistent issues by resetting all app settings.

4. Server Status: Sometimes issues can arise not from the app itself but from server-side problems. If possible, you may want to check if there are any known outages or maintenance on HCMToGo’s end.

5. Support Contact: If none of the above solutions work, it may be helpful to contact HCMToGo support directly at [email protected] for more specialized assistance.
