Why business travelers carry their own connection
When you are traveling for work, every connection problem is a problem with the trip itself. A dropped call with a client, a deck that will not upload before the meeting, a VPN that will not hold on conference Wi-Fi. The fix is to stop depending on whatever network happens to be around and carry your own. Your phone runs a Citrus Mobile eSIM, your laptop tethers to it, and you are online and in control from the moment you land.
Online the moment you land
Install the eSIM before you fly, and it connects to a strong local carrier as soon as you arrive. No hunting for a SIM kiosk, no airport Wi-Fi portal, no waiting until the hotel. You walk off the plane already able to check messages, confirm the car, and join a call. Many cellular business laptops, like a Surface, ThinkPad, Dell, or HP, can run the eSIM directly so the laptop itself is online without a phone.
Security on the road
Public Wi-Fi in airports, hotels, and conference centers is convenient and risky. It is shared, often open, and a soft target for snooping. A tethered mobile connection is private to your own devices, which is why security minded travelers prefer it for anything sensitive. Pair it with your company VPN and you have a clean setup. We go deeper in eSIM vs public Wi-Fi for laptops.
No bill shock for the expense report
Carrier roaming can produce ugly surprises on a corporate card. Pay as you go from a known balance keeps the cost clear and easy to expense, with no per day roaming fees stacking up.

How much data does a work trip use?
| Activity | Rough data use |
|---|---|
| Email, calendar, messaging | 5 to 15 MB per hour |
| Video call with screen share | 0.6 to 1.2 GB per hour |
| VPN to office apps | Similar to the task, plus light overhead |
| Uploading a presentation | 20 to 200 MB |
| A typical work trip day | 1 to 3 GB |
A few days of meetings and email usually fit comfortably in a single top up.
What it costs
Pay as you go from $4, bonus credit on larger top ups, country rates on the rates page, and the pricing page for the full breakdown. For frequent travelers it is typically cheaper and far more predictable than carrier roaming.
