Information we collect
We collect information needed to process orders, deliver and activate eSIM services, provide support, prevent fraud, and improve our website and applications.
How information is used

Scope of this Privacy Policy
This Privacy Policy applies to personal information processed by ByteSim Limited in connection with the ByteSIM website, online store, mobile applications, customer support channels, eSIM products, and related services.
In this policy, “ByteSIM,” “we,” “us,” and “our” refer to ByteSim Limited. “You” and “your” refer to customers, website visitors, application users, and other individuals who interact with our services.
This policy does not apply to websites, applications, payment services, telecommunications networks, or other services operated independently by third parties. Their own privacy policies apply when you use those services.
Personal information we collect
The information we collect depends on how you interact with ByteSIM, which eSIM product you purchase, and which payment, device, network, application, or support services you use.
Information you provide
This may include your name, email address, telephone number, billing address, account details, destination, intended activation date, travel dates, order information, and messages sent to our customer support team.
Order and payment information
We may receive payment status, payment method, transaction identifiers, billing details, order amount, currency, fraud-screening results, chargeback information, and refund information from payment providers.
eSIM and device information
Depending on the product, we may collect your device model, operating system, eSIM compatibility information, installation status, activation status, ICCID, and device identifiers such as IMEI or EID where required to provide or troubleshoot the service.
Support and network information
When investigating a service issue, we may collect screenshots, APN settings, roaming settings, selected network, approximate location, error messages, connection status, and relevant service usage or diagnostic information.
Website and application information
We may automatically collect your IP address, browser type, device type, operating system, language, time zone, referring page, pages and products viewed, interaction events, and date and time of access.
Information from third parties
We may receive information from ecommerce platforms, payment providers, eSIM and mobile network suppliers, analytics providers, advertising platforms, affiliate partners, fraud-prevention services, and customer support providers.
How we collect information
- Directly from you when you place an order, create an account, provide activation information, request a refund, or contact customer support.
- Automatically when you browse our website, use our applications, or interact with our services.
- From SHOPLINE, payment processors, eSIM provisioning providers, telecommunications operators, roaming partners, analytics providers, and advertising platforms.
- Through cookies, local storage, log files, pixels, tags, web beacons, software development kits, and similar technologies.

We use personal information only for purposes connected with providing, operating, protecting, and improving ByteSIM services.

Legal bases for processing
Where European Economic Area or United Kingdom data protection law applies, we generally process personal information using one or more of the following legal bases:
- Performance of a contract: to process your order, deliver and activate your eSIM, provide connectivity, and handle support or refund requests.
- Legal obligations: to maintain required business records and comply with accounting, tax, fraud-prevention, consumer protection, and lawful disclosure requirements.
- Legitimate interests: to protect our services, prevent fraud, improve performance, understand customer needs, and operate our business where those interests are not overridden by your rights.
- Consent: where required for optional cookies, personalized advertising, certain analytics activities, or marketing communications.
Where processing is based on consent, you may withdraw your consent at any time. Withdrawal does not affect processing that took place before consent was withdrawn.
Cookies and similar technologies
Cookies are small files stored on your browser or device. We may also use pixels, tags, web beacons, local storage, log files, and software development kits.
Strictly necessary cookies
These cookies are required for essential functions such as the shopping cart, checkout, payment processing, account login, security, fraud prevention, language selection, and session management.
Because these cookies are necessary to provide the services you request, they generally remain active even when optional cookies are rejected.
Analytics and performance cookies
These cookies help us understand how visitors use our website, including traffic sources, pages viewed, popular products, customer journeys, technical performance, and completed purchases.
We use this information to improve website performance, usability, product presentation, and customer experience.
Targeting and advertising cookies
These cookies help us measure advertising performance, attribute purchases, limit repeated advertisements, build or exclude audiences, and show more relevant advertisements on third-party platforms.
They may be set by ByteSIM or by advertising partners such as Google, Meta, Microsoft, Reddit, TikTok, or other platforms enabled on our website.
Managing your cookie preferences
For visitors in regions where our Cookie Consent Banner is available, you can accept all cookies, reject optional cookies, or customize optional cookie categories.
Strictly necessary cookies remain active because they are needed for essential website functions such as security, shopping cart operation, checkout, and payment processing.
Visitors who do not see the Cookie Consent Banner may manage, block, or delete cookies through their browser settings. Disabling certain cookies may affect website functionality, saved preferences, analytics, or the relevance of advertising.
How we share personal information
We share personal information only where reasonably necessary for the purposes described in this Privacy Policy and subject to appropriate contractual, technical, or organizational protections where required.

We use SHOPLINE to operate our online store, manage website functions, customer accounts, checkout, orders, and related ecommerce services.

Payment information may be processed by SHOPLINE Payments, PayPal, card networks, acquiring banks, digital wallets, local payment providers, or other processors selected at checkout.
eSIM and network providers
We may share order, activation, device, or service information with eSIM provisioning partners, telecommunications operators, roaming partners, and network suppliers to provide and support your plan.

The providers involved in a particular transaction may vary according to your country, selected payment method, eSIM product, device, and available mobile network.
International data transfers
ByteSIM provides international travel connectivity and works with service providers located in multiple countries. Your personal information may therefore be processed outside the country or region where you live.
These countries may have privacy laws that differ from those in your jurisdiction. Where required, we use recognized transfer mechanisms or other safeguards, including contractual protections, to support the lawful transfer of personal information.
Data retention
We retain personal information only for as long as reasonably necessary for the purposes described in this policy, including to provide services, maintain transaction records, resolve disputes, prevent fraud, enforce agreements, and satisfy accounting, tax, regulatory, or legal obligations.
- Order and payment records may be retained for the period required by accounting, tax, payment, and consumer protection laws.
- Customer support records may be retained while needed to resolve a matter, maintain service history, improve support, or protect legal rights.
- Marketing information may be retained until you unsubscribe, withdraw consent, object, or the information is no longer needed.
- Analytics and cookie-related data may be retained according to the configured settings of the relevant provider and applicable law.
When information is no longer required, we may delete, anonymize, or securely isolate it unless continued retention is required or permitted by law.
How we protect personal information
We use reasonable administrative, technical, and organizational measures designed to protect personal information against unauthorized access, loss, misuse, alteration, or disclosure.
- Access controls and account authentication.
- Encrypted transmission where appropriate.
- Payment processing through specialist payment providers.
- Monitoring and fraud-prevention procedures.
- Restricted access based on operational requirements.
- Security requirements for relevant service providers.
Your privacy rights
Depending on your location and applicable law, you may have some or all of the following rights:
Submitting a privacy request
To submit an access, correction, deletion, objection, or other privacy request, contact us at service@bytesim.com with the subject line “Privacy Request”.
Please include your full name, the email address used for your order or account, your order number where relevant, the country or region where you live, and a clear description of your request.
We may need to verify your identity before completing the request. We will respond within the timeframe required by applicable law.
Certain information may be retained where necessary to comply with legal obligations, prevent fraud, complete transactions, establish or defend legal claims, or protect the rights of ByteSIM and others.
Where permitted by law, an authorized agent may submit a request on your behalf. We may request evidence that the agent is authorized to act for you.

Where permitted, we may send information about ByteSIM products, promotions, travel connectivity, special offers, or service updates.
You may unsubscribe from promotional emails by using the unsubscribe link included in the message or by contacting us.
Even after opting out of marketing, we may continue to send transactional or service-related communications, such as order confirmations, eSIM activation information, security notices, refund updates, and customer support responses.
Do Not Track and privacy preference signals
Some browsers offer “Do Not Track” settings or other privacy preference signals. Because there is no universally accepted standard for interpreting every signal, our website may not detect or respond to all browser-based privacy signals.
Where our Cookie Consent Banner is available, you can use it to accept, reject, or customize optional cookie categories. You can also manage cookies through your browser settings.
Children and minors
ByteSIM services are not directed to individuals under the age of 18, and we do not knowingly collect personal information from children for the purpose of providing services directly to them.
If you believe a child has provided personal information to us without appropriate authorization, please contact us so that we can review the matter and take appropriate action.
Changes to this Privacy Policy
We may update this Privacy Policy periodically to reflect changes to our services, technology, providers, business practices, or legal and regulatory requirements.
When we update this policy, we will revise the “Last updated” date at the top of the page. Where required, we may provide additional notice of material changes.
