FAQs About CIS Plans in Singapore
If you’ve ever wondered whether you’re missing out on better mobile value through your company, this guide is for you.
What Is a Corporate Individual Scheme (CIS) Plan?
A Corporate Individual Scheme (CIS) plan is a mobile service offering designed specifically for employees of organizations that have a partnership agreement with a telco provider. The goal of a CIS plan is simple: to provide better-value mobile plans to individuals through their workplace.
These plans are not business lines. Instead, they are personal mobile subscriptions that come with added perks and discounted rates because of your company’s affiliation with the telco. This makes them ideal for professionals who want generous data, roaming options, and lifestyle extras without signing up for a corporate group plan.
There are different types of CIS plans available depending on the provider. These typically include:
SIM-only plans with higher data limits and lower monthly fees
Handset bundles with subsidized or discounted phone purchases
Data-only or roaming plans for users who travel often or need international access
CIS plans are becoming increasingly popular in Singapore as more telcos team up with companies to offer flexible, no-contract options that give employees more value for their money.
How Does the CIS Program Work?
The Corporate Individual Scheme (CIS) works through partnerships between telcos and approved companies, government agencies, or educational institutions. When a company joins a CIS program, its employees gain access to special mobile plans that are not available to the general public.
Here’s how the process typically works:
Telcos partner with organizations to offer exclusive plan bundles.
Employees receive a unique sign-up link or promo code. This is often verified through a corporate email address or staff ID.
Once verified, users can browse and sign up for CIS plans online, with no need to visit a retail store.
Most CIS plans come with added advantages, such as:
No-contract terms, giving you full flexibility to cancel anytime
Handset discounts on the latest devices (with some telcos)
Bonus data or roaming allowances built into the plan
Lifestyle perks like streaming vouchers, entertainment deals, or AI tools
For Circles.Life CIS subscribers, all of this can be activated entirely online that is fast, easy, and hassle-free.
Who Is Eligible for a CIS Plan?
CIS plans are not open to everyone. They are specifically designed for individuals who are connected to an organization that has an active partnership with a telco provider.
You may be eligible if you are:
An employee of a partnered company or multinational corporation (MNC)
A civil servant, NSF (Full-time National Serviceman), or staff of a government agency
A student or faculty member from selected educational institutions (depending on the telco)
Each telco has its own list of approved organizations, so eligibility can vary.
How to Check if You Qualify
To see if you’re eligible for a Circles.Life CIS plan:
Go to the Circles.Life CIS page
Enter your work email address
If your company is on the list, you’ll receive a verification link to unlock access to all available CIS offers
The process is simple, secure, and takes just a few minutes. If your company is not yet part of the program, you may even be able to refer them for consideration.
Benefits of a CIS Plan
Signing up for a CIS plan comes with several advantages that go beyond just saving a few dollars each month. These plans are designed to give employees more value, more flexibility, and more perks compared to standard mobile subscriptions.
Here are some of the top benefits:
1. Exclusive Discounts
CIS plans often offer lower monthly fees on SIM-only plans or mobile bundles. These rates are not available to the general public and are typically reserved for employees of partnered companies.
2. More Data for Less
One of the biggest perks is the generous data allowance. Many CIS plans include double or even triple the data compared to regular plans at the same price point. This is especially useful for heavy data users who stream, work remotely, or travel often.
3. Early Upgrade Options
Some telcos offer early handset upgrade programs for CIS subscribers. This allows you to get the latest device sooner without waiting out a full contract cycle.
4. Freebies and Lifestyle Add-ons
Depending on the provider, CIS plans may include extras such as:
Free or discounted roaming data
Streaming vouchers for platforms like Netflix or Disney+
Movie ticket discounts
Access to tools like CirclesAI, powered by GPT-4o
These perks add real value to your plan and make the CIS experience more rewarding overall.
