eSIMs are steadily replacing physical SIM cards thanks to their convenience: you can activate data the moment you land without swapping SIM cards or hunting for a SIM counter at the airport. This guide shows you how to use a Go365 eSIM booked on Go365 in just three steps.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM built into your phone. Instead of inserting a plastic SIM card, you simply scan a QR code to install a data plan. Most recent phones (iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later) support eSIM.
Why use an eSIM when travelling?
When you go abroad or travel far from home, an eSIM helps you avoid expensive roaming charges and removes the worry of losing your original SIM. You keep your Vietnamese number to receive OTP codes while using high-speed data from a local eSIM plan.
Activate a Go365 eSIM in 3 steps
Step 1 — Buy a plan: Choose the right country and data size in the eSIM section on Go365. Once you pay, you will receive a QR code by email.
Step 2 — Install: Go to Settings → Mobile Data → Add eSIM and scan the QR code you received. Your phone will download the plan automatically.
Step 3 — Turn on data: When you arrive, set the Go365 eSIM as your mobile data line and enable data roaming for the eSIM line. You are now online.
Important notes
Install the eSIM while you are still at home (on Wi-Fi), but only turn on data once you arrive so you don't use up the plan early. Some plans start counting down from the moment of activation, so read the description carefully before buying.
