Hi there! I understand you're unable to make or receive calls on the Text Me app. Let's get this sorted out together.

To start, could you please let me know:

- Are you having trouble with both outgoing and incoming calls?
- Is your internet connection stable (Wi-Fi or mobile data)?
- Have you checked if your Text Me app is updated to the latest version?

Meanwhile, here are some initial steps you can try on your Windows device with the WebKit browser:

1. Ensure your internet connection is active and not in Airplane Mode.
2. Check that you have enough TextMe credits since calling regular phone numbers usually requires credits.
3. Update the Text Me app to the latest available version.
4. Clear your browser cache and cookies related to Text Me, then restart your browser.
5. Try logging out and logging back into your account.

If you've already tried these or if problems persist, we can explore deeper settings or account issues. Does that sound good? Also, please share if you encounter any error messages.

For detailed guidance, the Text Me support recommends checking credits and network as the first troubleshooting steps1 2.

Let me know how it goes!
