Have you ever been traveling and tried to do or buy something online but not been able to because of an OTP (One Time Password) step to a local phone number? When you are in your home or residence country it is fine; you have your phone number. But maybe you are traveling and you do not buy a SIM card in the country. Or maybe you just don't want to share your personal number with some random website that might use it to send you spam or sell the info.
Well, there is at least one free solution. I say free because many other websites offer the same or a similar service, but they require a payment. This one is completely free. During the time we were in India (last checked on January 2020) this website worked almost perfect every time we needed to order food to restaurants that wanted an indian phone number. When it did not work perfect with one of the phone numbers they offer we just switched to other and it made it.
Take into account though that, by using this trick, you may infringe the terms and conditions of the service in which you use it. We do not intend to say this is allowed everywhere nor can we be held accountable or responsible for any inconvenience or trouble you might have because of using the trick we tell you here. We only say we had no trouble and it was good enough for the use we did of it.
