Use cases for using Trip.com eSIM.
-1 Day 1GB Canada/USA eSIM costs $2. Ideal for short term data use by PetroCan prepaid subscribers. PetroCan (Good2Go) mobile data is $150/GB.
-China has a 72/144-hour visa-free transit policy for transiting passengers. 3 Days 2GB/day China eSIM costs $5
-1 Day 1GB USA eSIM for a day trip to USA costs $1.76.
Note about USA day trip using eSIM:
Roam eSIM "Canada/USA 5G eSIM" purchased from trip.com (or directly from roamesim.net ) , the "E-ticket" you receive in the email has a hot link (for iPhone) to start the install without printing/scanning QR code. This is extremely convenient for cross border day trip because: (1) you don't need to print the QR code at home; (2) you use your home cellular data network (before crossing the border) to install/activate without hunting for a WiFi café; (3) you get 5G speed ≈150 Mbps.
Caution about time zone
with some Trip.com eSIM
For "USA/Canada eSIM", the end of day is based on GMT+8.
For Vancouver in winter, the day ends @ 8 am. For Toronto in
winter, the day ends @ 11am.
For Vancouver in summer, the day ends @ 9am. For Toronto in
summer, the day ends @12 noon.
Easiest way to deal with this madness is to add Hong Kong
time to your iPhone's clock app.
Install/activate (scan the "USA/Canada eSIM" QR Code) after
12:01 am Hong Kong time, to avoid loosing 1 day of usage.
Read the package details
Following your purchase, you will receive an email from trip.com immediately.
The "Updated Voucher" includes a PDF attachment containing a QR code.
(2) Print out the QR code on a piece of paper. You need a printer to do that, very inconvenient.
(or send the QR code to a travel companion's phone that can show the QR code offline).
(or send the QR code to your laptop or tablet)
(3) Before you scan the QR code, you must have WiFi and destination country's cell signal.
If you prefer not to deal with this complexity, use Airalo and other eSIM providers that separate the install and activate process into two separate steps with their app.
With Airalo, you can install with WiFi only, then activate later when you have destination country's cell signal. Airalo process is in harmony with natural travel pattern.
(4) At destination country with WiFi (e.g. Starbucks) and destination country's cell signal, scan the QR code and start install/activate.
Note: Airports in China have public WiFi but each airport authority uses a different method to authenticate user access.
The general method is to (1) connect to airport WiFi first; (2) open a web browser to start an authentication dialog.
Beijing Capital Airport (PEK), Beijing Daxing Airport (PKX), Shanghai Pudong Airport (PVG), Shenzhen Baoan Airport(SZX) can authenticate using SMS sent to countries other than just China, or you can get a WiFi username/password from a dispensing machine by scanning your passport at the machine.
Shanghai Hongqiao Airport (SHA) can authenticate using SMS sent to countries other than just China.
For other airports in China, consult the website Airports in China.
😢 If you have no success in accessing public WiFi at the airport, delay install/activation the Trip.com eSIM until you find a friendly WiFi café or hotel WiFi.
Try Airalo eSIM, you can install/activate Airalo eSIM at home or WiFi at departing airport; and walk out of the plane fully connected at destination. You can use WhatsApp, WeChat, Skype, Facebook Messenger, YouTube, iMessage, Facetime, Uber, Google email, Google Chat, Google Maps, etc.
Bad situation:
At a destination airport, train station, cruise ship port without WiFi
Very bad situation:
For some eSIM, if you try to install in a country other than the destination country, Secondary line will get stuck in an "activating" loop. Try to shut down the phone and restart. "activating" loop will continue until a WiFi connection, even than, it may take 10-20 minutes to calm down.
Worst case situation: phone reset may be required.
Settings...General...Reset...Reset All eSIMS (that includes erasing your home eSIM).
The graphics below shows an installed/activated eSIM, cellular data is coming from Secondary line (eSIM).
Check "Package Details" to see if "Data Roaming" needs to be ON or not. Most likely you need data roaming to be ON.
Tap the Secondary line...
Set the Data Roaming switch on, green is ON (see graphics below).
APN is usually set automatically.
If you don't get any data:
Check "Package Details" to find the APN setting.
Settings...Cellular...Secondary line...Cellular Data Network
The APN should be given in the email sent by trip.com after purchase.
Final check:
Settings...Cellular....Cellular Data
Secondary is checked
Do not touch "Allow Cellular Data Switching"
I leave my primary line in the "ON" position because:
- I want to receive inbound SMS while abroad (inbound SMS is free for Canadian carriers).
- If someone calls my primary line, I can see who calls but not answer, otherwise roaming charges kick in.
- I can return calls or check voice mails using Viber or fongo for a small fee.
