Frequently Asked Questions

An eSIM is a SIM that is built into your phone. You add a plan by scanning a QR code instead of putting in a card. See How it works.

ChoEsim sells prepaid travel eSIM data plans issued by a third-party provider.

You can order with your name and email address, or sign in with Google or an email address if you prefer. If you order without an account, your QR code is shown on the confirmation page in the browser you paid with and is emailed to you, with a private link to open it again. If you want your eSIMs in My eSIMs, sign in.

Your QR code is sent to that address. Typing it twice helps make sure it reaches you.

The site is available in many languages. Most translations are still awaiting review, so wording may not be perfect outside English and Vietnamese.

Your phone must support eSIM and be carrier-unlocked. Dial *#06# and look for an EID to help find out. It is not a guarantee, so confirm your exact model with its manufacturer. See Device check.

Our Device check page shows examples of phones by brand that are listed as eSIM-capable. They are examples only, not a test of your phone and not a guarantee. The manufacturer and your carrier's unlock status have the final word, so please check your exact model with the manufacturer.

The plan page shows the price, data allowance, validity and coverage. Those details apply when you place your order. Plans on the site are either fixed-allowance plans or pay-per-day plans, where you choose the number of days.

Prices are in US dollars (USD). If you pay with PayPal you are charged in USD. If you pay with OnePay, the amount is converted to Vietnamese dong (VND) at the rate shown at checkout and you are charged in VND.

Through the payment provider shown at checkout. You are taken to that provider's page to pay.

If you have a discount code, it can be applied to an order. Each code has its own limits.

Yes. Choose a plan, add it to your cart and pay at checkout.

Connect to stable Wi-Fi, then scan your QR code from your phone's eSIM settings. On iPhone the path is Settings, Cellular, Add eSIM, Use QR Code. Menu names depend on your phone, so see the Installation guide.

Install on stable Wi-Fi so the setup does not get interrupted.

Use manual installation: enter the SM-DP+ address and activation code yourself. The steps are in the Installation guide.

You can install on Wi-Fi before you go. Check your plan's details for when its validity starts, because that depends on the plan.

Yes. Hotspot is supported on all our plans, so you can share your data with your laptop, tablet or other phones. Devices that connect to your hotspot use the same data allowance as your phone.

Our plans are data plans. If a plan includes anything else, its plan page says so.

Coverage and plan details are those on the plan page. Speed and availability can vary by place and by device, and we do not promise a particular speed.

Please do not. Your QR code and activation details are private and just for you.

In the installation email sent to the address on your order, and on the confirmation page in the browser you paid with (for up to 24 hours). If you ordered while signed in, also in My eSIMs once your eSIM has been prepared.

Check your spam or junk folder. If you ordered without an account, you can ask for your QR code again on the Your eSIM page with your order number and the email address of the order. If you ordered while signed in, check My eSIMs. Still missing? Write to support@choesim.com with your order number. See the Delivery policy.

Open the email we sent you and use "Open my eSIM". Lost the email? Ask us to send it again on the Your eSIM page. We limit how often you can ask. For security, we show the same message whether or not the details match an order, and we send the email only to the address on the order. Sending a new email makes older links stop working.

If you sign in to an account whose email address is verified and is the same as the address on the order, we can add earlier orders to My eSIMs once they are complete. If your email address is not verified, we cannot add them, but you can still open them with the link in your email.

Write to support@choesim.com at once with your order number. What we can do depends on the case. See the Refund policy.

You can cancel an eSIM that has not been installed or activated and has not used any data within 14 days of your order, and we refund 100% of what you paid. Where a refund is due, an operator refunds it, in full or in part, to the payment method you used (PayPal or OnePay). See the Refund policy for what qualifies and how long it takes: We usually reply within 24 hours, and a technical review takes 1 to 3 business days once we have the information we need..

When we refund an order in full, the eSIM on that order no longer appears in My eSIMs, the private link in your email and the confirmation page no longer show it, and the installation email cannot be sent again. If the eSIM has not been installed or used, we cancel it with our provider first, so it can no longer be installed. A partial refund does not cancel or hide your eSIM.

Write to support@choesim.com. Include your order number if you have one. We email you an invoice when your payment succeeds. If your order is cancelled and refunded in full, we cancel that invoice and email you a cancellation notice.
