Frequently Asked Questions
Not sure about something with eSIMs or how they work? Find quick answers below.
What is an eSIM?+
An eSIM (embedded SIM) is a SIM built into your phone β no physical card needed. You just scan a QR code to activate a data plan right on the device, with no store visit and no swapping SIMs.
Does my phone support eSIM?+
Most recent phones do: iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later. Check under Settings > General > About > SIM status, or ask your manufacturer to be sure.
How does a TripWise eSIM work?+
Pick a country and data plan, pay online, then receive a QR code by email and on screen. Scan the QR in your phone's mobile settings and you're online right away.
Can I use the eSIM alongside my physical SIM?+
Yes. Most eSIM-capable phones support dual SIM β keep your home SIM for calls and OTP messages, and use the TripWise eSIM for mobile data while abroad.
What payment methods do you accept?+
TripWise supports bank cards (Visa, Mastercard, local ATM), e-wallets/QR, and PayPal. English customers pay in USD via PayPal.
How soon do I get the eSIM after buying?+
Right after a successful payment, the system issues your eSIM and shows the QR code on screen and by email β usually within about a minute.
Can I top up data while abroad?+
Yes. You can return to TripWise and buy another plan for the same country any time during your trip, as long as you have internet (via Wi-Fi or your current eSIM).
Do you offer eSIMs that cover many countries?+
Yes. Besides single-country eSIMs, TripWise.vn offers Regional eSIMs (one eSIM for a whole continent) and a Global eSIM (100+ countries) β ideal for multi-country journeys.
How do I use a promo code?+
At checkout, enter your promo code in the "Promo code" field and press Apply. The discount is deducted from your total before you confirm payment.
What is your refund policy?+
Because eSIMs are issued instantly after payment, refunds are generally not available once activated. If a technical fault makes the eSIM unusable, please contact support and we'll help.
How do I contact support?+
Email TripWise support or leave your order details, and our team will get back to you as soon as possible.
