It’s unsafe when you use temporary phone numbers online from an unreliable source or any other platform.
You should not use a secondary number from a local provider as it can store all your personal information even when you’re dating with your affairs, and also these providers can steal your data and system passwords and hand it to unethical hackers.
Nowadays, China, Japan and the U.S. are challenging the whole world with their advanced rapidly increasing technology, especially Chinese hackers who are threatening Indian cybersecurity.
It’s become an unusual activity for thousands of global hackers to fake people by their original mobile number, or now many internet local sites are providing online temporary phone numbers and faking millions of online consumers.
