A. If you are outside India and need to use the eMudhra App, consider using a virtual phone number service that provides Indian phone numbers. Services like Google Voice or other VoIP providers may offer this feature. Sign up for a service, obtain an Indian number, and use it to register on the app.
B. Another workaround is to ask a friend or family member in India to register on your behalf using their number. They can then share the verification code with you, allowing you to access the app.
