Kyivstar Revamps 'Happy Day' Offer: Unlimited Data for 1 UAH from 2026.

Revamped 'Happy Day' Promotion

According to Novyny.live: Kyivstar has announced a major update to its 'Happy Day' promotion, which will allow subscribers to purchase unlimited data for a full 24-hour period for just 1 Ukrainian hryvnia. This updated offer is scheduled to launch on January 21, 2026. In addition to the unlimited domestic data, the operator will also provide an extra 0.3 GB of roaming data starting from the same date in 2026.

Changes to Rate Plans

As part of these updates, Kyivstar will also be phasing out several of its existing rate plans, effective from January 21, 2026. The following plans will no longer be available for new subscriptions:

• ALL TOGETHER Light 2025
• ALL TOGETHER Light Contract 2025
• ALL TOGETHER Cool 2025
• ALL TOGETHER Top Contract 2025

These changes to both promotions and rate plans reflect the company's ongoing efforts to adapt to evolving subscriber needs and a shifting telecommunications market. Kyivstar is one of Ukraine's leading mobile operators, and such strategic moves are common in the highly competitive telecom sector.

The enhanced 'Happy Day' promotion could significantly boost customer loyalty for Kyivstar, as unlimited internet access for a nominal fee represents a highly attractive value proposition.

Simultaneously, the retirement of specific legacy plans suggests a strategic shift by the company towards newer products and services that better align with modern consumer demands and the competitive landscape.
