eSIM for Business Travelers

Corporate roaming bills are unpredictable and expensive. A travel eSIM gives you a fixed cost per trip, keeps your work number active, and eliminates roaming surprises.

The problem with corporate roaming plans

Most business roaming plans charge $10–$15/day for a data "pass" — often with speed limits and fair-use caps buried in the fine print. A two-week trip to Japan or Europe costs $140–$210 in roaming charges before you factor in calls. A travel eSIM for the same trip costs $15–$30 with full LTE speeds.

Setting up dual SIM for business travel

1
Keep your work SIM in the phone — calls, SMS, and corporate apps continue to use your work number.
2
Install the travel eSIM for data — browsing, email, Teams/Slack all route through the cheaper eSIM data.
3
Set travel eSIM as Cellular Data. Set work SIM as Default Voice.
4
Enable Wi-Fi Calling on your work SIM — this routes work calls over your eSIM data for clearer international call quality.
5
Disable data roaming on your work SIM — prevents the corporate SIM from accidentally using data at roaming rates.

Expensing eSIM plans

LTE.app purchases include a receipt and order confirmation suitable for expense reports. For Premium members, LTE.app provides a monthly statement of all purchases. The per-trip cost of an eSIM plan is categorizable as "communications" or "IT expenses" in most corporate expense systems.

Multi-country business trips

1
Europe trip visiting multiple countries: buy one Europe eSIM plan — covers all EU countries, UK, and Switzerland on one plan.
2
Asia Pacific trip (Japan + South Korea + Singapore): buy separate plans per country, or a Southeast/Northeast Asia regional plan.
3
No new QR needed for each country: purchase additional plans through the LTE.app and they activate on your existing eSIM profile.

Frequently asked questions

Can I keep my work phone number while using a travel eSIM?

Yes. Your work SIM stays in the phone. Your number stays active for calls and texts. The travel eSIM only handles internet data. Colleagues, clients, and your corporate PBX can still reach you on your work number.

Is eSIM secure enough for business use?

Yes. eSIM technology uses the same cryptographic authentication as physical SIMs. LTE.app does not log your browsing data or resell traffic data to third parties — a critical distinction for business users in regulated industries.

How do I get a receipt for eSIM purchases?

LTE.app sends a purchase receipt with every order. It includes full transaction details suitable for expense reporting.
