The principles that apply when you order, issue, install and use eSIMs from esimuni.
eSIM is a digital product issued individually. Check your device and plan before paying; only click “Confirm issuance” once you are ready to receive the QR code.
These Terms govern access to the website and the ordering, payment, issuance and use of eSIMs provided by MOBI MEDIA CO., LTD under the esimuni brand.
By confirming an order, the customer confirms that they have read, understood and agreed to these Terms, the Payment Policy, the Refund Policy and the Privacy Policy published on the website.
esimuni provides electronic data eSIMs, not physical SIMs, and they normally do not include a phone number, SMS or voice calls unless the product description states otherwise.
Customers are responsible for checking that their device supports eSIM, is carrier-unlocked, and matches the country, network, validity and data allowance of the plan before paying.
Customers must provide an accurate email address to receive the order confirmation, the eSIM management link and support information. An order is only confirmed after the system records a successful payment.
Before paying, customers can review the destination, data plan, validity, quantity, delivery email and total transaction value. The available methods are published on the Payment Methods page.
After successful payment, esimuni sends a confirmation email with the order management link. The customer actively clicks “Confirm issuance” once ready to receive the eSIM.
After confirmation, the system sends an issuance request to the eSIM partner. This usually takes about 30–60 seconds but can take longer due to carriers, partners or technical issues. The QR code is displayed on the My eSIM page and sent to the registered email address.
An issuance request that has been sent cannot be cancelled instantly. Because an eSIM is a digital product issued individually for each order, refunds after this point are considered under the Refund Policy.
Customers need a stable internet connection during installation, must follow the instructions, and should only turn on data roaming in the supported country or region.
Each QR code can normally be installed only once and may be tied to the first device it is installed on. Do not delete the eSIM, switch devices or rescan the code without guidance from the support team.
Data allowance, speed policies, hotspot sharing, validity and when the usage period starts apply as described for each specific plan.
Customers can access their orders using their email plus an authentication method provided by esimuni, such as an OTP code or a secure link. Customers must not forward authentication codes or eSIM management links to unauthorised people.
esimuni may temporarily suspend access or request additional verification if it detects signs of fraud, unusual access, or a risk to orders.
The country, validity or data allowance cannot be changed by the customer once the transaction is complete. Cancellation and refund requests are assessed based on issuance, installation, activation and usage status, and the cause of the issue.
The conditions, exclusions, documents required and processing times are set out in detail in the Refund Policy.
Connection quality depends on the coverage, infrastructure and policies of carriers at the destination. Actual speeds may vary with location, device, time, usage levels and local conditions.
To the extent permitted by law, esimuni is not liable for indirect costs such as roaming from a primary SIM, replacement devices, third-party services, or losses arising from installing or using the eSIM against the instructions.
Customers should create a support ticket providing the order number, email, a description of the problem and any necessary screenshots. esimuni may ask the customer to cooperate with troubleshooting steps before deciding on a resolution.
Chat channels such as WhatsApp and the Fanpage are for quick exchanges; tickets are where requests requiring reconciliation or formal resolution are received and tracked.
These Terms are governed by Vietnamese law. Disputes are preferably resolved by negotiation first; if no agreement is reached, the parties may ask the competent authorities to resolve the matter.
esimuni may update the Terms to reflect its products and legal requirements. The version applying to a transaction is the version published when the customer confirms the order, unless the law provides otherwise.
