With the World Cup kicking off and summer approaching, millions of Brits are packing their bags for sunnier destinations. The smartphone has become an indispensable travel tool, but using it abroad can lead to nasty bill shock upon returning home.
What is eSIM and How Does It Help?
eSIM technology, embedded in modern smartphones, allows users to activate a virtual SIM without needing a physical card. This can be a game-changer for avoiding high roaming fees. After Brexit, roaming rules became more complicated and often pricier, with UK mobile operators offering less flexibility. While some plans still include free EU roaming, it's usually on higher-priced tariffs. Previously, travelers had to pay for add-ons or buy local SIM cards, both costly and inconvenient.
Thankfully, eSIM services like Airalo provide a simple solution. The Airalo app for iPhone and Android lets you purchase pay-as-you-go, no-contract mobile data plans for your destination country. For example, football fans heading to the World Cup in the USA can buy a 10GB plan for 7 days at just £17. This should suffice for a week of travel if you avoid streaming video constantly. The app connects to local networks like T-Mobile and Verizon, automatically switching for optimal signal.
Airalo Unlimited eSIM Plans
In late 2025, Airalo launched Unlimited eSIM plans, offering up to 3GB per day at full speed. If exceeded, speeds drop to 1Mbps, ensuring you never go offline completely. The US Unlimited plan for 7 days costs £21, providing 21GB of full-speed data over the week—equivalent to just £1 per GB. Users can also use their phone as a hotspot for other devices.
How to Get Started with eSIM
Check if your phone is eSIM-compatible by looking for an eSIM option in the mobile network settings. Most iPhones since the iPhone XS (2018) have eSIM, but ensure your device is network-unlocked. Airalo's installation process is straightforward:
- Open the Airalo app or website and choose your destination and plan.
- Install the eSIM via app, QR code, or manual setup.
- Set the eSIM as your mobile data line and enable data roaming.
- Activate it upon arrival and connect to a local network.
Other eSIM Services
Airalo isn't the only option. Competitor Holafly also offers Unlimited plans, but with restrictions that are not transparently disclosed. Another rival, Saily, provides a premium $59.99 per month plan with 30GB of high-speed data before throttling to 1Mbps. For most travelers, Airalo's competitive pricing and reliability make it a top choice.
With eSIM, you can enjoy your holiday without worrying about mobile costs. It's a small trick that brings peace of mind.
