How can I use a virtual card to sign up for trials and avoid charges after cancellation?

To add to what @tim-khorev said, if your goal is primarily testing across different browsers or devices, you might want to explore LambdaTest’s cloud-based virtual machines for cross-browser testing.

While not a traditional VM in the strictest sense, LambdaTest offers cloud-based virtual environments where you can run your site or app on different browsers like Chrome, Firefox, and Safari across various operating systems and mobile devices.

The best part is that LambdaTest’s free plan gives you enough minutes to conduct basic daily tests, and it’s incredibly quick to boot up, which is perfect if you’re looking to do cross-browser testing without the hassle of managing VMs yourself. This can save you a lot of setup time and help you get immediate feedback for your tests.
