You are wrong, check the link above. Uber first ride is free or better to say you need to pay before your 2nd ride.
For new acc you need new mobile, new device and new email id. So hacks are available for rooted device and there are OTP sellers in the market which gives you service at certain price.
In short, it has become a huge racket. If I am not wrong daily losses of Uber due to these frauds are in range of lakh / day in India only.
Moreover, they also provide international uber ride in any other country too @ 30% of the fare but paid in Paytm in INR.
Recently they were giving 3 free rides in users account by paying 60rs Paytm. Same free ride when you refer someone from your personal uber account.
I paid them money, instead of giving me single referral, my uber acc is now overloaded with referrals. Daily 25-30 new accounts created which I can see on my email but Uber app can show only 20 referrals at a time. Sooner or later Uber will ban my account, till then enjoying unlimited 50rs rides
