New users often try to do everything at once; taking one step at a time reduces the chance of mistakes.
1. First, view the APK
Download the r77 APK first, then install; on many Android phones you have to grant permission for unknown apps.
2. Verify login details
When logging in to r77, check whether the number and password are correct; if they are, login is much faster.
3. Prepare payment options
Many people in Dhaka use bKash, Nagad, Rocket; having accounts opened beforehand makes it easier.
4. Pay attention to small screens
On midday trips or at home, even with slow 3G networks the app runs, so first look closely at the home screen and the menu.
