Idea — Express Bill Payment Portal

Published by UXtoCODE on

Good User Experience


Glad to share my experience of Idea Express Bill Payment Portal.

I have idea postpaid connection. Usually, I pay my mobile bill via Idea Express Bill Payment Portal. Recently they revamp the portal I observed UI enhancements, sharing my thoughts on their UX in this post..

When I entered the mobile number, the system automatically validates my mobile number without waiting to fill out other details or users explicit submit action.

Curiously I checked some functional scenarios. I entered non idea number, and the system instantly gave me an error saying

This is not an Idea number. Switch to Idea now! “With a hyperlink. Label colour also changed for valid and invalid details.

It’s a clever lead generation strategy instead of showing a normal error to the user.

I tried the postpaid mobile number in prepaid mobile recharge section, system shows appropriate error with prepaid portal link .i.e. “This is a postpaid number. Please visit Postpaid Bill Pay page.”

Also, I can only enter numbers in a mobile number field.
