If you’ve ever opened a mobile bill after an overseas trip and nearly spilled your coffee, you know the pain of bill shock from international roaming charges. These costs can climb rapidly thanks to background data updates, automatic app syncing, and call routing quirks. However, there are many practical, proven ways for businesses to take control of their travelling workforce. For business travellers, and especially IT Directors who frequently manage teams on the move, keeping roaming bills predictable isn’t just a nice-to-have it’s essential for budget control and helps avoid potentially awkward conversations with your Finance Director.
Disable data roaming and use Wi-Fi as your base connection
Turning off data roaming is one of the best tips to help avoid unexpected charges. Disabling this feature in your phone’s settings or by switching to airplane mode, you effectively cut off the mobile data tap. That means no background app updates, no stealthy cloud syncs, and no accidental streaming on mobile networks. However, this has its drawbacks for your travelling employees.
While in airplane mode, they can still connect to Wi-Fi networks for email, messaging, and calls through apps like Microsoft Teams, WhatsApp, or Zoom. But, to do this they have to join free or low-cost Wi-Fi, which has some security implications. It also means where there is no Wi-Fi available, they’ll remain offline.
Use international plans or all-inclusive VIP Tariffs
For frequent travellers, an international plan may be the most predictable solution. Many carriers offer daily roaming bundles per user/per device that include fixed data, call, and text allowances. However, whilst daily costs with these plans seem reasonable, they quickly rack up as they contain hidden fair usage policies and any data use over the fair usage is expensive.
VIP all-inclusive roaming tariffs such as the Opus VIP tariff, take it a step further by offering flat monthly rates for unlimited roaming usage. These can eliminate overage risks entirely, though they require careful analysis to ensure the cost is justified by travel frequency.
Swap to a local SIM or install a travel eSIM
If your team requires constant connectivity while abroad, a local SIM card or travel eSIM can slash your international data roaming cost. Local SIMs, often sold at airports or convenience stores, give you domestic rates for calls and data in the country you’re visiting.
Travel eSIMs, on the other hand, are digital SIMs you can activate before departure. This approach is particularly useful for multi-country trips since many eSIM plans cover several destinations in one package.
Set a roaming spending cap before you travel
A roaming spending cap is your insurance policy against bill shock, many businesses are not aware this can be done. Many carriers let you set a monthly cap after which roaming services are blocked. This not only keeps expenses predictable but also forces a pause to reassess your data usage mid-trip and avoid excessive fees on return.
Some carriers can send real-time alerts when you’re close to the limit, which is useful for avoiding sudden service cut-offs while still maintaining budget control. And, for frequent business travellers, IT admins can apply caps to business accounts to ensure company-wide compliance.
Rely on Wi-Fi calling and internet-based communication apps
Wi-Fi calling routes voice calls over the internet, bypassing traditional roaming fees entirely. If your carrier supports it, enabling Wi-Fi calling is as easy as flipping a switch in your phone’s settings.
When Wi-Fi calling isn’t an option, internet-based apps like WhatsApp, Zoom and Teams can handle both calls and messages over Wi-Fi. This not only saves cost but also enables richer communication through video calls and file sharing without touching your roaming allowance. For larger teams, this approach can also standardise communication tools, making collaboration much easier across countries.
