Streamline your digital life with a multi-SIM plan

Want to max out your phone plan's potential without scouring every inch of Singapore? Time to consider the Multi-SIM route with Circles.Life.

What is a Multi-SIM Plan?

A Multi-SIM Plan allows you to use more than one SIM card under a single mobile subscription. With Circles.Life, this means you can add a data-only SIM to your existing phone plan. It’s ideal for keeping multiple devices connected using the same pool of data, without the need for separate plans or hotspot sharing.

How Does the Multi-SIM Card Work?

A multi-SIM setup works by linking an additional SIM card, typically data-only, to your main mobile number and plan. This second SIM uses the same data allowance, giving you mobile internet access on another device without needing extra subscriptions or relying on Wi-Fi.

Circles.Life also offers eSIM support as a second SIM card option. An eSIM is a digital version of a SIM card that can be activated directly on compatible devices. It allows you to stay connected on multiple devices or run both your primary and secondary lines on one device, depending on your setup.

Whether you choose a physical SIM or an eSIM, Circles.Life makes it easy to stay connected across all your devices with one convenient plan.

Key Features of Multi-SIM Plans

Feature

SIMs can be configured as data-only or with full voice/SMS capabilities.

Common Reasons to Choose a Multi-SIM Plan

Unreliable Public Wi-Fi Networks

Public Wi-Fi may be convenient, but it often comes with slow speeds, connection drops, and security risks. A multi-SIM plan gives you stable mobile data on devices like tablets or laptops, so you can stay productive and protected anywhere you go.

Striving to Maintain a Work-Life Balance

Separating work and personal life can be tough, especially when using the same device for everything. With a multi-SIM setup, you can dedicate one device for work and another for personal use, both connected to your main plan. This helps create clearer boundaries without the cost of a second full plan.

Children Tend to Consume Mobile Data Quickly

If your kids stream videos, play games, or use educational apps on a tablet, they can easily burn through your mobile data. A multi-SIM lets you share your existing data plan with their device, making it easier to monitor usage without needing a separate subscription. Use the Circles.Life app to track real-time data usage. One plan, two devices: whether it's for two of your mini-me's or sharing with one, manage that screen time like a pro.

Managing SIM Cards While Travelling is a Hassle

Switching SIM cards while abroad can be time-consuming and confusing. A multi-SIM plan with an eSIM option lets you stay connected on a second device or local network without removing your primary SIM. It’s a seamless way to manage roaming or keep access to your main line while using a travel-friendly device.

Key Advantages of Multi-SIM Plans

Seamless Work-Life Separation

Multi-SIM plans let you use one SIM for work and another for personal use, all under one data plan. This setup allows you to manage calls, apps, and notifications across different devices or profiles, making it easier to keep boundaries between work and life without needing two phone plans.

Backup Connectivity

If your main phone loses signal or runs out of battery, having a second SIM in another device means you can stay online. Whether it’s a tablet, portable hotspot, or backup phone, multi-SIM plans offer an extra layer of connection when you need it most.

Smarter Data Management

Instead of juggling multiple data plans, a multi-SIM setup lets you share one data pool across several devices. This makes it easier to track usage, avoid overages, and ensure each device gets the data it needs without waste.

Cost Savings While Travelling

Rather than buying separate SIM cards for travel, you can use a second SIM in a local device while keeping your primary number active. With eSIM support, you can also avoid roaming charges by activating a local plan digitally while staying connected to your main line.

Device Sharing

With a data-only SIM, you can give access to tablets, smartwatches, or modems without needing a separate subscription. This is perfect for team members, assistants, or housemates who need temporary access to mobile data.

Ideal for Families

Multi-SIM plans are great for families who want to share one plan across different devices. Parents can monitor and manage data use, children can stay connected on their own devices, and everyone benefits from a single, simplified bill.
