Terms and Conditions

TailSim provides prepaid eSIM data plans so travelers and remote teams can connect to the internet in 100+ destinations without needing a physical SIM. By purchasing or activating a plan, you accept these Terms and Conditions in full.

Payment is processed securely through MercadoPago, which accepts the major credit and debit cards, bank transfers, and account balance.

To use TailSim you must be at least 18 years old and provide truthful information when buying a plan. You agree to

• Use the service lawfully and in accordance with these Terms.
• Not engage in fraudulent, abusive, or illegal activity.
• Respect the intellectual property rights of TailSim and its providers.
• Not share, resell, or transfer QR codes or plans to third parties.

After purchasing a plan you will receive a QR code and installation instructions by email. The eSIM must be installed on a compatible device within the timeframe stated in your plan. Once installed, follow your device's instructions to connect to the destination network.

Confirm your device supports eSIM before purchasing. Once the eSIM is installed or activated, it is no longer eligible for a refund.

Our plans are designed for personal and reasonable use. On unlimited or high-volume plans, network operators may apply fair-use policies that temporarily reduce speeds after heavy consumption. TailSim is not responsible for traffic managed by third-party networks once the eSIM is active.

Refunds are available, with a 5% deduction to cover payment gateway fees.

Cases where NO refund applies

• Not being available for diagnostics with our technical support, or failing to report the issue in time.
• Phone locked by the original carrier (closed bands, SIM lock).
• Phone theft or loss.
• Signal dead zones (mountains, basements, remote areas).

For full details, see our Refund Policy.

Coverage and speeds may vary due to operator network maintenance, geographic location, weather, or local regulatory restrictions. We do not guarantee full availability of third-party networks. If your device is damaged for reasons outside our responsibility or is lost, the plan payment is non-refundable.

Unless otherwise required by law, these Terms and Conditions are governed by the laws of the Republic of Colombia. Any dispute or claim related to our service will be resolved exclusively in the competent courts of Colombia.
