How to Activate Your Travel eSIM on Arrival
A travel eSIM has two moments: you install it at home, and it activates when your phone first connects to a network in the destination. Get the settings right before you fly and activation takes care of itself when the plane lands. Here is the routine for both.
Install and activation are different
- Install is the download onto your phone. You do it at home on Wi-Fi, from the install link on iPhone or the QR code on other phones.
- Activation is the first connection to a local network in the destination. You don't press a button; it happens when the phone finds the network.
Your plan's validity starts at activation, not at purchase and not at install. Buying a month early and installing a few days early costs you no days. For the full journey, see how a travel eSIM works.
Before you fly: a five-minute check
- The eSIM is installed and labelled, for example "Travel". If not, follow the steps for iPhone or Android.
- Travel is the mobile data line. iPhone: Settings → Cellular → Cellular Data. Android: in the SIM settings, under Mobile data. Names vary by phone.
- Data Roaming is on for Travel. iPhone: Settings → Cellular → Travel → Data Roaming (under Cellular Data Options on some versions). Why: data roaming settings explained. Android: open the travel SIM's settings and turn on Roaming.
- Data roaming is off for your home line, and automatic data switching is off. This keeps your own carrier from charging you for data.
- Your home line handles calls and SMS, so your number stays reachable. More in keep your WhatsApp number abroad.
The travel line will say "No Service" at home. That is expected. Don't delete it; an install code usually works once.
On the way
- Plan covers your home country? A regional plan such as a Europe eSIM bought in France can connect at home and start its validity before you leave. Keep the travel line switched off in Settings until you have left.
- Keep Airplane Mode on during the flight as usual.
- Layovers: a regional plan can activate in a transit country if that country is covered, which starts your validity early. If you don't need data during a layover, keep Airplane Mode on, or switch the travel line off in Settings, until your final stop.
When you land
- Switch off Airplane Mode. The phone looks for a network.
- Give it a minute or two. The travel line should show a network name and signal bars.
- Open a web page or a map to confirm data works.
- If nothing happens, toggle Airplane Mode on and off once. Then check the two settings that cause most problems: Data Roaming on for Travel, and Travel selected for mobile data.
- Still nothing after a few minutes? Restart the phone. If that doesn't do it, work through no service after landing, then eSIM not working for the next steps, including choosing a network by hand.
How you know it worked
- The travel line shows a network name, not "No Service" or "SOS".
- Pages and maps load with Wi-Fi switched off.
- Messages send on WhatsApp or iMessage without Wi-Fi.
The network name may not be one you recognise. Travel eSIMs connect to local partner networks, and the destination guide for your country lists the ones in use, for example the Japan guide.
After activation
Watch your data
A fixed plan stops when its data runs out. An unlimited plan has a daily high-speed allowance shown on the plan, after which speed drops until the next day. If you need more, top up from your account page with a deliberate tap. Nothing renews by itself.
Crossing a border
A regional plan such as Europe keeps working in each country it lists, and the phone switches network as you cross. A country plan stops at the border. Check the list on the product page before a day trip.
Coming home
Set your home line back as the data line and turn its data on. You can leave the travel eSIM in place or remove it once the plan has ended.
If it never activates
It happens rarely, and it is our problem to solve. Email hello@e-sim.net with your order id. If the eSIM never connected to a network, you get a full refund. Once it has connected, the plan counts as used. Ready for your next trip? Start on the eSIM page, or go straight to Japan.
Questions
Does installing the eSIM start the clock on my plan?
No. Validity starts when your phone first connects to a network in the destination.
Do I really need Data Roaming on?
Yes, for the travel line. The eSIM is a visitor on the local network, so the phone treats it as roaming. Keep data roaming off on your home line.
How long does activation take?
Usually a minute or two after you switch off Airplane Mode. If nothing happens after a few minutes, toggle Airplane Mode once, then restart the phone.
