It is perfect for digital nomads and frequent travellers

Global coverage – access to multi-network support across countries
Space-saving – ideal for dual-SIM usage or devices without SIM trays

Roaming – Staying with Your Home Network Abroad
Roaming lets you use your existing mobile number overseas by connecting to partner networks in your destination. Your carrier works behind the scenes to provide access abroad without requiring a new SIM card.
Benefits of Roaming
Keep your existing number – no need to update contacts
No SIM swap required
Automatic connection upon arrival
Ideal for business travel and short trips
Common Limitations of Roaming
Higher cost compared to local or eSIM plans
Limited data allowances
Possible speed throttling after usage limits
Not always available in remote destinations
How Roaming Works and How to Activate It
Your carrier partners with foreign networks to provide roaming access.
Activation is usually automatic, but some plans require enabling roaming in your mobile settings or subscribing to a roaming bundle.
Check your data and call rates before travelling to avoid bill shock.

Local SIM – Budget-Friendly, But Inconvenient

When to Choose a Local SIM

What You Should Consider When Choosing a Travel SIM
Needless to say, an overseas connection should give you the most bang for your buck, with minimum fuss.
All of these options provide voice, text, and data services to keep you connected while travelling. But each has its nuances:
Cost
Historically, local SIM cards were the most affordable choice for international travellers. But with technological advancements, travel eSIMs have emerged as competitive digital alternatives.
Plus, roaming services have also evolved with more cost-effective packages. Circles.Life is leading the charge on this front, offering stellar international roaming plans. And if you thought those were great, wait until you explore our travel eSIM. With competitive calling, texting, and data rates, we ensure that your savings allow you to indulge in that dreamy holiday activity instead. And the cherry on top? Unlimited data!
All these mean more choices for a traveller. But which one should you go for?
Coverage
As thrilling as venturing off the beaten path can be, being left with zero connectivity isn't ideal. Local SIMs are often tied to one service provider, which means that you may experience dead zones. Step outside your provider's coverage area, and you could find your signal bars rapidly shrinking to zilch.
In contrast, travel eSIMs and roaming plans offer more extensive coverage, partnering with multiple providers to ensure continuous connectivity. Journeying to a remote area? No worries, Circles.Life's network partners ensure you’re always within reach of a strong network.
Convenience
Remember the hassle of searching for a local SIM vendor in a new airport? Or juggling luggage and fumbling over a tiny SIM card?
With eSIMs and roaming plans, those days are over. Activating Circles.Life's travel eSIM is as easy as scanning a QR code. Do it from anywhere - whether you're lounging at the airport or en route to your hotel.

FAQs
1. Can I use an eSIM and physical SIM simultaneously for travel?Yes, most modern smartphones with dual SIM support allow you to use an eSIM for travel data while keeping your physical SIM active for calls or texts. This is great for staying reachable on your home number while enjoying local rates.
2. Are travel eSIMs compatible with all phones?No. Travel eSIMs require a device that supports eSIM functionality. Most newer iPhones, Google Pixels, and Samsung Galaxy phones are compatible, but it's best to check your device’s specs or carrier compatibility before purchasing.
3. How fast is eSIM activation compared to buying a local SIM at the airport?eSIM activation is usually much faster. Once you receive a QR code or install via an app, activation can take just a few minutes. In contrast, buying a local SIM may involve waiting in line, showing ID, and adjusting phone settings.
4. Will roaming plans charge me extra for calls and texts, or is it all-inclusive?That depends on your provider and plan. Some roaming packages are all-inclusive, while others charge per use. Circles.Life roaming plans offer bundled minutes and data so you know exactly what you’re paying for before you travel.
