Business Travel Roaming Guide Cut Costs (2026)
Corporate roaming charges accumulate in individual expense reports where no one sees the full picture. AT&T charges $10/day per device. A team of 10 on a 5-day international trip generates $500 in roaming costs before anyone reviews it. eSIMs replace that with $80-150 total, centrally billed, with one invoice.

The corporate roaming cost problem
Roaming charges are the one travel cost that hides in individual expense reports. No one sees the total until it is too late.
AT&T International Day Pass costs $10/day per line. A 5-day business trip costs $50 per employee. That number sounds manageable on one expense report. Scale it to a team and the math changes fast.
Per-employee cost breakdown
AT&T: $10/day per device. A 5-day trip costs $50 per employee. Verizon TravelPass is also $10/day. T-Mobile Go2Chile includes some international data, but most corporate devices are on AT&T or Verizon plans where every day abroad is billed separately.
Team cost scaling
A team of 10 on a 5-day trip generates $500 in roaming charges. A team of 25 generates $1,250. A team of 50 generates $2,500 for a single week-long trip. None of this is visible as a single line item. It appears across 50 individual expense reports, each under the reimbursement approval threshold.
Annual travel budget impact
Companies with 4+ international trips per year multiply the problem. A 25-person team on 4 annual trips at $1,250 per trip accumulates $5,000 per year in carrier roaming charges. That is a telecommunications cost that appears in zero telecommunications budget reviews, because it routes through travel and expense instead.
The eSIM alternative costs $8-15 per employee per trip. For the same 25-person team across 4 annual trips, total cost is $800-1,500. The saving is $3,500-4,200 per year, captured as a line item in the telecommunications budget where finance can see and approve it.
| Scenario | Team size | Trip length | Carrier roaming | eSIM cost | Savings |
|---|---|---|---|---|---|
| Small team, 1-week trip | 10 employees | 5 days | $500 | $80-150 | $350-420 |
| Mid-size team, 1-week trip | 25 employees | 5 days | $1,250 | $200-375 | $875-1,050 |
| Large team, 2-week trip | 50 employees | 10 days | $5,000 | $400-750 | $4,250-4,600 |
| Annual: 4 trips, mid-size team | 25 employees | 4 x 5 days | $5,000 | $800-1,500 | $3,500-4,200 |
Carrier roaming assumes AT&T International Day Pass at $10/day per device. eSIM cost assumes Airalo destination-specific plans purchased via Airalo for Business with volume pricing.
Most corporate expense policies auto-approve charges under $25-50. A single day of roaming at $10 never triggers manual review. Five days at $50 stays under most thresholds. The cost passes through finance unnoticed, every trip, for every traveler. eSIM purchases at $8-15 per trip are slightly lower individually, but they are centralized, visible, and subject to policy. That is the real advantage.
IT policy considerations for eSIM deployment
eSIMs introduce questions around device management, security policy, and corporate procurement that IT teams need to answer before rollout.
BYOD versus corporate devices
Corporate devices under IT control are easier to standardize. IT can issue approved eSIM plans before each trip, require employees to install the plan before departure, and verify installation through device compliance checks. BYOD environments are more complex. Employees use personal phones with personal carrier plans. IT cannot require eSIM installation on personal devices, but it can make eSIM reimbursement the only approved method for international data, which makes the financial incentive clear.
MDM compatibility with eSIM
Mobile Device Management platforms including Jamf, Microsoft Intune, and VMware Workspace ONE support eSIM QR code distribution as managed content. IT pushes the QR code to managed devices via the MDM portal. Employees scan it from the managed documents folder without needing a separate email. Full MDM-level eSIM profile management, where IT remotely installs or removes eSIM profiles, is available on supervised Apple devices via Apple Configurator and requires a carrier partnership. For most corporate deployments, QR code distribution via MDM covers the practical requirement.
Security implications
eSIM data routes through the local carrier at the destination, the same infrastructure used by local residents. This is identical to standard carrier roaming from a network security perspective. The local carrier handles the connection. Corporate data passes through their infrastructure before reaching the internet. Without a VPN, this is the same exposure as any mobile connection. With a VPN, traffic is encrypted before it leaves the device, regardless of which carrier handles the connection. For regulated industries, VPN use is non-negotiable on any mobile connection abroad, eSIM or roaming.
Saily addresses the VPN gap
Saily includes VPN from Nord Security in every plan. Employees on Saily get encrypted data without a separate VPN subscription or app. IT can configure Saily as the approved provider and VPN compliance becomes automatic. For finance, healthcare, and legal teams with strict data security requirements, Saily removes the compliance gap that exists with other eSIM providers.
Corporate procurement process
Airalo for Business offers purchase orders and centralized invoicing, which allows procurement teams to treat eSIM plans as a telecommunications vendor relationship rather than employee reimbursements. The platform generates a single invoice per order, which procurement can process through standard vendor payment workflows. Volume discounts begin at 10+ plans per order. For larger organizations, annual framework agreements with Airalo Business set pricing for the year and simplify each trip's procurement.
eSIM deployment for teams
Bulk purchasing, QR code distribution, and centralized billing replace the per-employee expense report model.
Bulk purchasing via Airalo for Business
Airalo for Business is a dedicated portal for corporate eSIM procurement. Travel managers log in, select the destination country and data plan, choose the number of plans needed, and purchase the full batch in one transaction. The portal generates individual QR codes for each plan, all in one downloadable package. Volume pricing applies automatically at 10+ plans.
Holafly Teams
Holafly offers team purchasing through direct sales contact. Their unlimited daily plans are better suited for employees who need heavy data usage without tracking daily consumption. Contact Holafly's business team to arrange bulk pricing. The management interface is less developed than Airalo's, but unlimited data removes the risk of employees running out of data mid-trip and reverting to carrier roaming.
QR code distribution before the trip
Send each employee their QR code by email at least 48 hours before departure. Include installation instructions for both iOS and Android. Ask employees to confirm installation before boarding. Installation takes under 5 minutes and requires no IT assistance. Employees scan the QR code in their device Settings and the eSIM activates when they land at the destination. No IT staff needs to be present at departure or arrival.
Per-device activation with no IT hands-on requirement
Each employee activates their own eSIM plan. The process is: open Settings, select Add eSIM or Cellular Plan, scan the QR code. The plan installs in under 2 minutes. No IT technician touches the device. No physical SIM card is swapped. Employees set the eSIM as their data line and keep their corporate SIM active for calls. IT involvement ends at QR code distribution.
Centralized billing and data monitoring
Airalo for Business provides a dashboard showing each employee's plan status, data remaining, and usage history. Travel managers see every plan in one view. Finance receives one invoice per order rather than 25 individual expense reports. Data usage monitoring lets managers identify employees who exhausted a plan early and might need a top-up before carrier roaming charges appear.
Expense reporting for eSIM purchases
eSIM costs are telecommunications expenses, not travel expenses. The distinction matters for budget codes, tax treatment, and audit trails.
How to categorize eSIM expenses
eSIM plans are telecommunications expenses. They belong in the same budget category as mobile phone plans, corporate phone contracts, and data services, not in travel and entertainment. Most corporate expense systems include a telecommunications subcategory. Code eSIM purchases under that category so they appear in telecommunications spend reports alongside carrier bills.
Receipt documentation
Airalo, Holafly, Saily, and Nomad all send email receipts immediately after purchase. For individual purchases, the email receipt is sufficient. For Airalo Business bulk purchases, the portal generates a formal invoice with line items per plan, which satisfies standard accounts payable requirements. Keep receipts in the same place as phone bill documentation.
Comparison to carrier roaming on corporate phone bills
Carrier roaming charges appear on the monthly corporate phone bill as line items per device per day. They are buried in the bill detail rather than visible as a distinct travel expense. eSIM purchases create a separate, visible receipt at the time of purchase, which is easier to audit and approve before the trip rather than discovering the cost after the bill arrives.
Tax deductibility in the US and UK
In the US, business telecommunications expenses are deductible under IRS Section 162 as ordinary and necessary business expenses. eSIM plans used for business travel qualify under the same rules as mobile phone and internet expenses. In the UK, HMRC treats business phone and data expenses as allowable deductions when used wholly and exclusively for business purposes. Keep receipts and document the business trip they relate to. Consult your tax advisor for jurisdiction-specific treatment.
Security comparison: roaming versus eSIM versus eSIM with VPN
The connection type matters less than whether you encrypt the traffic. Here is what each option actually provides.
Carrier roaming
Standard carrier roaming routes data through a roaming partner carrier in the destination country. Your phone connects to the local network under your home carrier's agreement. Data travels through the local carrier's infrastructure before reaching the internet. Encryption depends on the local carrier's network configuration and whether the apps in use apply their own encryption (HTTPS, TLS). The data path passes through potentially foreign-government-accessible infrastructure in countries with mandatory carrier data retention laws.
eSIM: same routing, lower cost
eSIM data routes through the same local carrier networks as roaming. The underlying security profile is equivalent. An employee on an Airalo eSIM in Germany connects to the same Deutsche Telekom infrastructure as an AT&T roaming customer on the same network. The difference is cost and who bills you, not network path or security posture. For general business use, eSIM without VPN offers the same security as standard roaming without VPN.
eSIM with VPN: encrypted from device
Adding a VPN to an eSIM connection encrypts all traffic before it leaves the device. The local carrier sees only encrypted packets destined for the VPN server. Application data, login credentials, email contents, and file transfers are not visible to the local carrier or any network observer between the device and the VPN endpoint. This is the recommended configuration for regulated industries.
Requirements by industry
Finance (SOX, GDPR, SEC): VPN mandatory on any mobile connection abroad. Healthcare (HIPAA): encrypted connections required when accessing protected health information. Legal: attorney-client privilege considerations require encrypted connections when discussing client matters. General business: VPN is best practice but not legally mandated in most jurisdictions. Configure VPN before departure. In China, configure obfuscated protocols before entry.

Travel policy template language
Copy this paragraph into your corporate travel policy. Adapt the approved provider list and maximum plan value to your organization.
Most corporate travel policies do not mention eSIM because the technology is newer than the policy. Adding a single paragraph closes the gap, sets employee expectations before departure, and establishes eSIM as the approved method. It also creates the paper trail finance needs to treat eSIM purchases as reimbursable telecommunications expenses.
Sample policy paragraph
“Employees traveling internationally shall disable data roaming on corporate devices and install a pre-approved eSIM data plan from the company's approved provider list before departure. Approved providers for 2026: [Airalo for Business] / [Saily] / [Holafly]. eSIM plan costs are reimbursable as telecommunications expenses, not travel and entertainment. Maximum reimbursable plan value: $X per trip day or $Yper trip total. Employees must retain the purchase receipt and code the expense under telecommunications in the expense system. Carrier roaming charges incurred while a pre-approved eSIM plan was available are not reimbursable without prior written approval from the travel manager.”
Notes on adapting this template
- Set the maximum reimbursable value based on your most common destination. A $20/trip cap works for most 5-day business trips.
- If your team travels to regulated markets (China, Russia), add a VPN requirement: “All data connections in [country list] require an approved VPN active at all times.”
- Update the approved provider list annually. Prices and corporate program availability change.
- The non-reimbursability clause for carrier roaming is the key enforcement mechanism. Without it, employees default to the path of least resistance (roaming) and submit the bill.
Business travel eSIM questions, answered
Can IT manage eSIMs remotely via MDM?
Partially. IT can distribute eSIM QR codes via email or MDM-pushed content, which removes the hands-on step of scanning a code in person. However, eSIM profiles themselves are not MDM-managed on most platforms as of 2026. Apple Configurator supports eSIM deployment on supervised iOS devices via cellular plan assignment, but this requires device supervision and carrier partnership. For most corporate deployments, the practical model is: IT purchases eSIM codes, distributes them via email before the trip, and employees scan the QR code themselves. No hands-on IT involvement at the point of activation.
Do eSIM providers offer corporate accounts?
Airalo offers Airalo for Business, a dedicated portal for corporate procurement. It provides centralized billing, bulk QR code purchasing, a management dashboard for tracking usage per employee, and volume discounts starting at 10+ plans. Holafly offers team management through direct sales contact. Saily and Nomad handle corporate purchases on a case-by-case basis through their support channels. For a team of 20+, contact Airalo Business directly for volume pricing that is not available through the public store.
How do I justify eSIM costs to finance?
Show the comparison directly. AT&T International Day Pass costs $10/day per line. A 5-day business trip costs $50 per employee. A team of 10 costs $500 for one trip. An eSIM plan for the same trip costs $8-15 per employee, or $80-150 for the team. The savings on a single trip often exceed $350-420. For a company with 4 international trips per year across a 10-person team, the annual saving is $1,400-1,680 versus carrier roaming. Finance teams understand line-item reduction. Present it as a telecommunications optimization, not a travel expense.
Is eSIM data secure for business use?
eSIM data routes through the same local carrier networks as regular roaming, so the underlying connectivity security is equivalent. The practical security difference comes from whether you add a VPN. Without a VPN, data on any cellular network (eSIM or roaming) is subject to the carrier's infrastructure security. For regulated industries — finance, healthcare, legal — a VPN is mandatory regardless of connection type. Saily includes a built-in VPN from Nord Security at no extra cost. Other providers require a separate VPN subscription. For general business use with standard corporate tools, eSIM without VPN is as secure as standard roaming.
Can employees keep their corporate number while using eSIM?
Yes. Dual SIM functionality lets employees keep their corporate SIM active for calls and texts while routing all data through the travel eSIM. Set the corporate SIM as default for voice and SMS. Set the eSIM as the default data line. Incoming calls still arrive on the corporate number. Outgoing calls use the corporate number. All internet traffic, apps, and email use the cheaper eSIM data connection. This is the recommended setup for business travelers. On iPhone: Settings > Cellular > Default Voice Line and Default Data Line control each independently.
What about countries where VPN is restricted?
China blocks most commercial VPN protocols at the network level. Russia restricts VPNs not approved by Roskomnadzor. The UAE prohibits VPN use for activities that are illegal under UAE law, but permits business VPN use for corporate access. For China: configure a VPN with obfuscation protocols (Shadowsocks, V2Ray) before entry, as configuration inside the country is difficult. For Russia and UAE: consult your corporate legal team before the trip. In all cases, download and configure your VPN before departure, since app stores in restricted countries may not offer the VPN apps you need.
How do I handle eSIM for a conference of 50+ attendees?
Use Airalo for Business. Purchase eSIM plans in bulk for your destination country. The portal generates individual QR codes for each plan, which you distribute via email before the conference. Each attendee scans their code on their own device. No IT staff presence required at the venue. For 50 attendees on a 5-day conference, expect to spend roughly $400-750 total for eSIM data versus $2,500 in carrier roaming at $10/day per person. Airalo Business provides a single invoice for the full order, which simplifies expense reporting and tax documentation.
