slimduet® Reusable SIM Card Kit
Taisys Technologies Co., Ltd
slimduet® Thin SIM provides cost-saving roaming services across 80 countries and regions, offering travelers a convenient and affordable way to stay connected globally. As a co-brand of Taisys, slimduet® is part of the GreenRoam Alliance — an initiative aimed at addressing critical telecom challenges such as customer ownership risks, OTT-induced revenue loss (ARPU decline), price erosion, profit margin compression, and net neutrality concerns.
The goal of this project was to create a compact, travel-friendly packaging design for a reusable SIM card kit.
The design needed to reflect slimduet’s brand identity while ensuring practicality for international travelers who frequently swap SIM cards.
Design Concept
• The design emphasizes mobility, reusability, and convenience.
• The colour palette uses bright, travel-related tones to convey freshness and freedom.
• The illustration of a luggage tag symbolizes travel and global connectivity — the essence of slimduet’s service.
• The layout maintains a clean, modern look that aligns with the digital, borderless lifestyle of modern travelers.
Functional Design Features
• Compact Cardholder
The inner cardholder features a precisely die-cut slot for securely holding the SIM-eject pin, ensuring users have all the necessary tools in one convenient location.
• Reusable Pocket Package
The outer sleeve is designed as a small pocket, allowing users to store their original SIM card safely after swapping.
• Clear User Guidance
The packaging includes concise instructions, service details, and a QR code for app download, making activation easy and user-friendly.
The final design successfully balances aesthetic simplicity and functional precision. It enhances brand recognition for slimduet® while delivering a seamless travel experience for users.
The reusable design also aligns with the GreenRoam Alliance’s sustainability vision, reducing packaging waste and supporting environmentally responsible travel technology.
