eSIM for business trips: staying connected through every meeting
A business trip differs from a holiday in one key way: you can't just be offline for a couple of hours. A client is waiting for an email, colleagues need you to join a video call, and your bank might send a code at the exact moment your phone is silent in roaming. Here is how to set up your connection for a business trip so your laptop, calls and bank SMS all keep working at once, without surprises.
Laptop in the meeting room: sharing data from your phone
If your presentation or spreadsheet opens on a laptop rather than a phone, you need hotspot mode. Before the trip, check on the plan page whether it supports tethering — it isn't guaranteed by default on every plan. On the ground, hotspot switches on in a couple of steps in your phone settings, and the laptop connects to it like an ordinary Wi-Fi network.
Keep in mind that hotspot use burns through data noticeably faster than working from the phone itself: email with attachments, cloud folder syncing and any background updates all run at full speed unless you limit them.
Turn off background cloud syncing on your laptop before a meeting — otherwise it can eat the whole channel right when you need a video call.
Video calls: how much data to budget for
A group video call with screen sharing uses data noticeably faster than messaging or a voice call. If your trip has several video meetings a day, budget data with a margin: audio calls and email fit into a couple of gigabytes for a day of intensive work, while regular video calls with presentations can easily add as much again.
If the connection at the meeting venue is unreliable — say, a conference room with thick walls — check with the organisers in advance whether there's guest Wi-Fi, and keep mobile data as the backup channel rather than the other way round.
Your home number for bank SMS and two-factor codes
Most travel plans are data-only, with no calls or texts to the new number. That's actually convenient: you don't have to change the number linked to your banking apps, work email and two-factor authentication, because your home SIM stays in the phone and keeps receiving codes and notifications, while the eSIM handles mobile data.
Before you fly, make sure roaming for SMS is enabled on your home SIM — otherwise even a card physically in the phone won't receive a bank code.
Check SMS roaming on your home number in advance — without it, bank codes won't arrive even if the SIM card is physically in the phone.
A route through several cities or countries in one trip
If a business trip covers several countries back to back — say, a meeting in one city and a conference in another — a single regional plan for the whole trip is more convenient than swapping eSIMs at every border. It saves time at the airport and removes the risk of being offline in the first hours in a new country while you look for a place to buy a SIM.
You can buy and install the eSIM ahead of time from home or the office, and switch it on after landing in the first city on the route, so your phone is already connected by the time you leave the terminal.
- Check your trip route against the regional plan's country list
- Install the eSIM in advance while you have stable office Wi-Fi
- Turn on data roaming for the new line right after landing
- Keep your home SIM in the phone for calls and codes
- Check hotspot support on the plan page beforehand
What to do the day before you fly
Your phone needs to support eSIM and not be locked to a single carrier — worth checking in advance rather than at the airport. A plan is bought online with no passport needed and installed via QR code or a quick-install button in a few minutes.
If your data runs out mid-trip — say, because of an unplanned extra call — you can buy a top-up package online straight from your phone, without breaking up your working day to find a phone shop.
