It's difficult to say definitively whether Shyam Rajasthan Cabs, provided by Udaipur Cabs Service, is reliable and affordable. Here's why:

* **Limited information about Udaipur Cabs Service:** I couldn't find much online information about Udaipur Cabs Service itself. While they might be a legitimate company working with Shyam Rajasthan Cabs, more details would be helpful for assessment.

* **Shyam Rajasthan Cabs might be the main provider:** Searching for "Shyam Rajasthan Cabs" reveals a website offering taxi services from Jaipur to Udaipur [https://www.makemytrip.com/car-rental/jaipur-udaipur-cab-services.html](https://www.makemytrip.com/car-rental/jaipur-udaipur-cab-services.html). This suggests Shyam Rajasthan Cabs might be the main provider and Udaipur Cabs Service might be a reseller of their service.

Here's what you can do to assess Shyam Rajasthan Cabs:

* **Check Shyam Rajasthan Cabs website:** Their website ([https://www.makemytrip.com/car-rental/jaipur-udaipur-cab-services.html](https://www.makemytrip.com/car-rental/jaipur-udaipur-cab-services.html)) details their services, car options, and claims about experience and customer satisfaction. Look for reviews or testimonials on the site, but be aware these might be curated.

* **Search online reviews:** Look for independent reviews of Shyam Rajasthan Cabs on Google Maps, travel forums, or independent review sites.

* **Compare prices:** Get quotes from Shyam Rajasthan Cabs and other taxi service providers on travel portals like MakeMyTrip or Goibibo to compare affordability.

By following these steps, you can get a better sense of Shyam Rajasthan Cabs' reliability and affordability for your trip from Jaipur to Udaipur.
