Terms of service

Last updated: 3 November 2026

Who we are

COTA eSIM is a product of PINHAN GROUP LLC, a Delaware limited liability company with its registered address at 501 Silverside Road, Suite #105 - 5653, Wilmington, DE 19809, USA ("we", "us"). PINHAN GROUP LLC is the seller of every plan purchased on our website and in our apps.

You can contact us at [email protected].

By creating an account, placing an order or using an eSIM bought from us, you agree to these Terms, our Privacy Policy (/en/legal/privacy) and our Refund Policy (/en/legal/refund). Orders are placed by accepting the Pre-contract information (/en/legal/pre-information) and the Distance Sales Agreement (/en/legal/distance-sales) at checkout.

The service

COTA eSIM sells prepaid mobile data plans for travellers, delivered as eSIM profiles. Plans are data-only; they do not include a phone number, voice calls or SMS.

Connectivity is provided by local mobile network operators through our eSIM suppliers. We resell access to these networks; we do not operate a mobile network ourselves.

The service is intended for users aged 18 and over.

Your account

You can create an account with a one-time code sent to your email address, or by signing in with your Apple, Google or Facebook account. Whichever route you choose, your account is tied to your email address: different sign-in routes pointing at the same address open the same account.

You can also buy without an account. In that case your eSIM is delivered to the email address you enter, so please make sure it is correct.

Keeping your email and sign-in accounts secure is your responsibility; anyone who can access them can also access your account. You can delete your account at any time from within the app.

Plans, prices and payment

Before you buy, each plan page shows the price and currency, the data allowance, the validity period and the countries covered. The total amount you will be charged is shown at checkout before you pay.

Prices can be displayed in several currencies. You are charged in the currency shown at checkout; if your card is in a different currency, your bank may apply its own exchange rate and fees.

Payments are processed by our payment provider, Stripe. Your card details are entered directly into Stripe's secure form; we never see or store your full card number.

Promo codes and wallet balance can be applied at checkout under the conditions shown for each code. Wallet balance can only be spent on purchases in our service; it cannot be withdrawn as cash.

Delivery

Once your payment is confirmed, your eSIM is normally delivered within minutes. The QR code and installation details are shown on the order confirmation page, sent to your email address and, if you have an account, kept under "My eSIMs".

Keep your QR code and activation code private: anyone who scans them may be able to install your eSIM. Most eSIM profiles can be installed only once; if you delete an installed eSIM from your device, it usually cannot be reinstalled.

If we cannot deliver your eSIM, we will tell you and handle it under our Refund Policy.

Device compatibility is your responsibility

Before you buy, you are responsible for making sure that your device supports eSIM and is carrier-unlocked, meaning it is not locked to a single mobile network operator. A carrier-locked device will not connect with our eSIMs.

Our list of compatible devices (/en/supported-devices) is for guidance only: eSIM support can differ by model, region and carrier. If you find out that your device is not compatible before you install the eSIM, see our Refund Policy.

Validity period and data allowance

Every plan has a data allowance and a validity period in days, both shown on the plan page. Unless the plan page says otherwise, the validity period starts when the eSIM first connects to a supported network at your destination; installing the eSIM does not start it.

A plan ends when its data allowance is used up or its validity period expires, whichever comes first. Unused data and remaining days are not refunded and do not carry over to another plan. Adding data to an existing eSIM is not currently supported; you can buy a new plan instead.

Usage figures shown in our apps come from our suppliers and may be delayed.

Fair use

eSIMs are for personal, lawful use on your own devices. You must not resell plans; use them in SIM boxes, SIM banks or for automated machine-to-machine traffic; run servers over them; or use them for spam, fraud or any other illegal activity.

Plans described as unlimited may be subject to speed limits or fair-use thresholds set by the network operator. Where these are known, they are shown on the plan page.

We may suspend an eSIM that is used in breach of this section. In that case no refund is due.

No guarantee of coverage or speed

Network coverage, availability and speed are provided by local operators and depend on your location, network congestion, buildings and terrain, your device and other factors outside our control. The network types shown on a plan page (for example 4G or 5G) describe what the partner networks support, not what you will receive at any given place or time.

We do not guarantee uninterrupted service, a particular speed or coverage at any specific location.

Remember to select the eSIM as your data line and to turn on data roaming for it. Charges that your home operator bills you because your phone kept using your home line are not our responsibility.

Right of withdrawal

If you are a consumer in Turkey, there is no right of withdrawal: under Article 15(1)(ğ) of the Distance Contracts Regulation, it does not apply to services performed instantly in electronic form or intangible goods delivered instantly, and eSIM plans fall into this category.

If you are a consumer in the EU or the UK, your 14-day right of withdrawal ends when delivery of the eSIM begins: at checkout you expressly request immediate delivery and acknowledge that you lose the right once delivery begins.

Independently of this, our Refund Policy gives you a full refund for an eSIM that has not been installed or activated, if you request it within 30 days of purchase. Details: Pre-contract information (/en/legal/pre-information).

Refunds

Refunds are governed by our Refund Policy: /en/legal/refund

Limitation of liability

To the fullest extent permitted by law, the service is provided "as is" and "as available". Our total liability for any claim relating to a plan is limited to the amount you paid for that plan.

We are not liable for indirect or consequential losses, such as lost profits, missed bookings or connections, or charges from other service providers.

Nothing in these Terms limits any liability that cannot be limited by law, or your mandatory rights as a consumer.

Changes to these Terms

We may update these Terms from time to time. The version in force when you place an order applies to that order. The date at the top of this page shows when the Terms were last updated.

Governing law

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-law rules. If you are a consumer, you also keep the protection of the mandatory consumer laws of the country where you live.

If you are a consumer in Turkey, you may also apply to the Consumer Arbitration Committee (Tüketici Hakem Heyeti) or the Consumer Court (Tüketici Mahkemesi) of your place of residence or of the place where the transaction was made, within the monetary limits set each year by the Ministry of Trade.

Translations of these Terms are provided for convenience. In case of conflict the English text prevails, unless mandatory consumer law gives precedence to the text in your language.
