Frequently asked questions

Are Technocircle devices new or used?

Technocircle sells tested pre-owned electronic devices. Our selection includes smartphones, tablets, laptops, smartwatches and other devices that are ready for their next user.

The devices are not new. Each product page shows the device’s cosmetic condition, technical specifications and other important product information.

Before a device is listed for sale, its technical functionality is checked. Only devices that are ready to use and meet our sales standards are offered for sale.

What condition are the devices and batteries in?

The cosmetic condition of each device is shown on the product page as a condition grade. The condition grade describes only the visual condition of the device, such as possible signs of use, scratches or wear. Technical functionality and battery condition are checked separately.

  • A+ – Excellent cosmetic condition. The device looks like new. Only very small micro-marks may be present, which are generally not visible from arm’s length during normal use.
  • A – Very good cosmetic condition. The device may have light signs of use or micro-scratches that are generally not visible during normal use.
  • B – Good cosmetic condition. The device may have some visible signs of use, scratches or minor wear when viewed from arm’s length during normal use. A good choice for customers looking for a strong balance between price and condition.
  • C+ – More visible signs of use. The body or back cover may have deeper scratches, dents or wear marks. The device is technically tested and fully functional.

The screens of all devices listed for sale are checked, intact and suitable for normal use. The screen has no cracks or damage that would prevent normal use. Depending on the condition grade, the screen may have micro-marks or scratches, but no scratch or sign of use may interfere with normal use of the device.

Signs of use are cosmetic and do not affect normal use of the device. The exact appearance may vary slightly between devices within the same condition grade.

The battery capacity of smartphones and tablets is at least 80%. If a battery does not meet our sales standard, the device is not sold in that condition or the battery is replaced before sale.

For laptops, battery condition information is shown separately on the product page.

Because the battery is a consumable component in a used device, actual battery life depends on the device model, age, usage habits and settings.

Does the device come with a charging cable or charger?

The included charging accessories depend on the device type. Below you can see what is included with each type of device.

Smartphones: the device always comes with a compatible charging cable and a SIM eject tool. A wall adapter is not included.

Tablets: the device always comes with a compatible charging cable. If the tablet supports LTE, a SIM eject tool is also included. A wall adapter is not included.

Laptops: laptops are sold without a charger. The laptop price does not include a charger, and a charger must be purchased separately if needed. You can view laptop chargers here.

Smartwatches: smartwatches are sold without a charger. The charger is not included.

Do the devices come with a warranty?

Yes. All devices purchased from Technocircle come with a 12-month sales warranty.

The warranty covers technical faults and functional defects that are not caused by customer actions, incorrect use, drops, liquid damage, normal wear and tear or other exclusions listed in the warranty terms.

The battery is a consumable component in a used device and is covered by a separate 3-month sales warranty.

In the event of a warranty case, we will inspect the device and, where justified, repair it, replace it with an equivalent device or find another solution in accordance with the warranty terms.

More detailed information is available in our warranty terms.

Can I return the device?

Yes. When purchasing from our online store, you have the right to return the device within 14 days if it does not suit you.

The returned device must be in the same condition as when received, and all accessories included with the device must also be returned, such as the charging cable, SIM eject tool or any other included accessory.

Before returning the device, please remove all personal data, user accounts, passwords, SIM cards, memory cards and activation locks where possible.

To start a return, please follow the instructions on our returns page. More detailed terms are also available in our Refund and Returns Policy.

How quickly is the order shipped and delivered?

Orders are usually shipped on business days within 24 hours after payment has been received and the order has been confirmed.

For same-day dispatch, orders are locked on business days at 12:00. If the order is placed after 12:00, it will usually move to the next business day’s dispatch.

The warehouse does not operate on weekends or public holidays, so orders placed during these days will move to dispatch on the next business day.

In Estonia, orders usually arrive within 1–3 business days. Delivery times to Latvia and Lithuania are generally similar. For Finland and Sweden, delivery may take 1–2 business days longer, depending on the transport partner.

In Tartu and within the Tartu area, personal delivery of the device may be possible by agreement. To check this option, please contact us before placing the order.

The exact delivery time and available delivery options are shown in the cart and checkout before confirming the order.

Can I pay in instalments?

Yes. For eligible products, instalment payment options can be selected from the available payment methods at checkout.

The instalment terms, monthly payment amount and credit decision are shown in the payment partner’s environment before confirming the agreement.

The credit decision is made by the payment partner, and Technocircle cannot guarantee instalment payment approval in advance.

All available payment methods are shown in the cart and checkout before confirming the order.

Can I get additional photos or exact battery data for a specific device before buying?

All devices shown on our website have already been technically tested and are located in a logistics warehouse. Therefore, before purchase, we are not able to provide additional photos of a specific individual device, exact battery cycle counts or other device-specific information that is not shown on the product page.

The product page shows all important information available for the device: model, storage, colour, condition grade, technical specifications, battery information and other product-specific details.

We describe the cosmetic condition of devices cautiously so that customer expectations are realistic. The exact appearance may vary slightly between devices within the same condition grade.

We are also working on a photo library to provide customers with more real-life examples of different cosmetic grades in the future.

Does Technocircle have a physical store?

Technocircle operates as an online store, and we do not have a physical store or showroom where devices can be viewed before purchase.

The online store model helps us keep operating costs lower, because maintaining a physical store adds costs that are ultimately reflected in product prices. Our goal is to offer the best possible balance between price and quality.

All devices shown on the website have already been technically tested and are located in a logistics warehouse. Orders are placed through the online store, and the device is sent to the customer using the selected delivery method.

We are constantly working to make our online store as user-friendly, clear and trustworthy as possible. You can read more about Technocircle on our About us page.
