As a working lady that too single, I mostly travel alone. With bare minimum luggage.
If you are concerned about budget and safety now we are having few #MadeInIndia Apps. Let's explore those.

Once you get down at Kempegowda International Airport, can be from International or Domestic try to take the arrival gate number 15, near by domestic luggage belt number 4 and 5.

Once you there even if you are not on roaming you can access WiFi easily, you need to generate an OTP done. Any apps start working instantly. Why I prefer to use on Airport because my Data connection mostly very slow inside airports. Also it is very helpful for international traveler.

Transport :

Bangalore KIA airport is far from the main city if you are comfortable taking bus fine if not
you should try #Uber or #Ola , Personally I prefer #Uber cause they are well organized than Ola drivers. For me language is a problem most of the Uber guys can speak English, they are nice courteous too. Price difference depends on Ola's mood and weird pricing system.
