In an increasingly global business world, eSIMs for travel have emerged as a useful tool to keep using calls, SMS and mobile data, often promising cheaper prices than your existing carrier.

As global travel surges and digital connectivity become more essential than ever, Travel eSIMs are emerging as a popular alternative to international mobile access for businesses.
They promise:
Low-cost data access abroad.
Instant activation.
More flexibility, as phone makers move toward devices that only use eSIMs.
But beneath the surface, there are critical considerations that every user and business decision maker should be aware of.
1. Personal data risks: who’s watching your traffic?
The travel eSIM supply chain involves multiple players: mobile operators, aggregators, platform providers, and retailers. The more parties involved in the chain of service, the more chances of personal or business data being exposed.
A recent study from USENIX reveals that several travel eSIM providers route your data through foreign networks, including places with weaker privacy protections. This means your information could be exposed to third parties, such as unverified resellers. They might track your location, assign fixed IP addresses, or even disable your eSIM without warning.
And even more concerning, some providers have been starting data connections or receiving text messages without the end user knowing or agreeing. This hidden activity is worrying because it means users aren’t fully in control of what’s happening on their devices.
2. Roaming bill shocks: a mistake could cost you
Even with a travel eSIM installed, incorrect device settings can cause your primary SIM to incur roaming charges. These ‘bill shocks’ are often discovered too late, leaving users with hefty fees.
3. The fine print: hidden fees and restrictions
Many users overlook the terms and conditions when purchasing a travel eSIM. These documents often contain hidden fees, usage restrictions, or obligations that could lead to unexpected costs or service limitations.
4. Service quality: not always guaranteed
Unlike mobile operators, some travel eSIM providers lack robust infrastructure or customer support. You may experience poor service experiences, including dropped connections and unresponsive support teams.
5. Regulatory hurdles: not all markets are equal
In countries like the United Arab Emirates, India, and Thailand, eSIM activation may require the users to complete the eKYC (electronic Know Your Customer) verification process, making the buying journey more complex and prompting to provide additional personal information. This can delay access or even block usage depending on local laws.
6. Device settings: a set-up minefield
Setting up a travel eSIM isn’t always plug-and-play. Modern smartphones support up to 10 eSIM profiles, but only two can be active at a time. Configuring primary and secondary lines with multiple profiles in the background, especially on multi-SIM devices can be nothing short of a minefield often leading to high possibility of misconfiguration. This can create additional challenges for both customers and mobile providers.
Often, customers reach out to their provider’s support team to resolve roaming issues, only to discover that the problem stems from incorrect device settings. This back-and-forth leads to delays and frustration for everyone involved until the issue is finally resolved.
Travel eSIM technology unlocks the global mobility, but are you prepared for the risks?
There is a safer way to do business abroad
Convenience matters, but so does confidence. Travel eSIMs have unlocked a new era of global mobility, offering speed, flexibility, and low-cost connectivity for people on the move. But as we’ve seen, convenience often comes with trade-offs: unclear data handling, complex device settings, hidden terms, and the risk of roaming surprises that can undo the very savings travellers hoped for.
