Terms and conditions
Last updated: 14 September 2026
These general terms and conditions govern the purchase of mobile data eSIMs through the website https://glowisim.com. Please read them before you buy: by completing payment you confirm that you have read and accepted them. We send them to you with the order confirmation, and you can read them here whenever you like.
1. Who we are
The seller is Pablo Alfaya Fernández (“Glowi”), with tax ID (NIF) 29514449K and registered address at Calle La Santa María, 86, 41927 Mairena del Aljarafe (Sevilla). You can contact us at hello@glowisim.com. You will find our other details in the Legal notice.
2. What you are buying
Glowi sells prepaid mobile data plans for use abroad through an eSIM profile. The network is provided by the local operators at each destination through our wholesale provider; Glowi is not a telecommunications operator.
- Unless the plan details say otherwise, the service includes mobile data only: it does not include a phone number, calls or SMS.
- Each plan has a data allowance, a validity period in days and a destination or coverage area, which are shown in its details before you buy.
- The operators and network technologies (4G, 5G) shown are for guidance only and may vary depending on coverage in each area.
3. Requirements for using the eSIM
Before you buy, check that these requirements are met. If they are not, the eSIM will not work:
- An eSIM-compatible phone. You can check with our compatibility checker.
- An unlocked phone. A phone locked to its network will not accept the eSIM.
- An internet connection, such as Wi-Fi, to install it.
- Being of legal age and having the capacity to enter into contracts.
In general, an eSIM profile can only be installed once: if you delete it from your phone, it may not be possible to recover it.
4. How the purchase works
- You choose the destination, the plan and the number of eSIMs.
- You enter the email address where you want to receive the eSIM. You do not need to create an account.
- You review the order summary. Until you pay, you can go back and correct any details.
- You pay using one of the available payment methods.
- You receive the order confirmation on screen and by email, with its reference, the QR code and the installation instructions.
The contract is deemed concluded when payment is confirmed. We keep the electronic order document, which you can access by requesting it at hello@glowisim.com. The contract is concluded in Spanish. This English version is a courtesy translation; in case of discrepancy the Spanish version prevails.
5. Prices and payment
- Prices are shown in euros and include applicable taxes. As this is a digital product, there are no delivery charges.
- If you choose to view the website in another currency, the amount shown is for guidance only, and the charge is made in the currency stated at the time of payment.
- The charge is made when the order is confirmed. Payments are processed through a secure payment gateway; Glowi does not store your full card details.
- If you need one, we will issue the corresponding invoice.
6. Delivery, installation and validity
- We send the eSIM by email as soon as payment is confirmed. If you have not received it within a few minutes, check your spam folder and write to us.
- You can install it before you travel. Unless the plan details say otherwise, the validity period starts when the eSIM first connects to a network at the destination, not when you buy or install it.
- Some plans must be activated within a maximum period from the purchase. Where this applies, we state it in the plan details or in the confirmation email.
- The plan ends when the data runs out or the validity period ends, whichever comes first. Unused data is not refunded or carried over.
- To use the eSIM at your destination, you will need to turn on data roaming for the eSIM line.
7. Use of the service
The eSIM is for personal use and in accordance with the law. You may not:
- Resell or commercialise the service without our permission.
- Use it for unlawful activities, fraud, sending unsolicited bulk communications or attacks on computer systems.
- Use it in a way that harms the operators’ networks or the service of other users.
If we detect use that breaches these terms, we may suspend the service, with prior notice where possible.
Coverage and speed depend on the local networks, the area, network congestion and the device, and cannot be guaranteed at all times or in all places.
8. Right of withdrawal
As a consumer, you have 14 calendar days from the purchase to withdraw from the contract without giving any reason, provided that the eSIM has not been installed or activated.
Installing the eSIM marks the start of the provision of the service. When you buy, you expressly ask us to allow the service to begin during the withdrawal period and you acknowledge that, once the eSIM is installed or activated, you lose your right of withdrawal, in accordance with Article 103 of the consolidated text of the Spanish General Law for the Protection of Consumers and Users (Royal Legislative Decree 1/2007, TRLGDCU).
Top-ups. Data top-ups on an eSIM you have already bought are applied instantly and are non-refundable.
To withdraw, send us a clear statement at hello@glowisim.com with your order reference. If you like, you can use the model form below. We will refund the amount you paid without undue delay and, in any event, within 14 calendar days of receiving your request, using the same payment method you used and at no cost to you.
Model withdrawal form
To Pablo Alfaya Fernández, Calle La Santa María, 86, 41927 Mairena del Aljarafe (Sevilla), hello@glowisim.com:
I hereby give notice that I withdraw from my contract for the provision of the following service: [plan and destination].
Order reference and date ordered: […]
Name of consumer: […]
Address of consumer: […]
Signature of consumer (only if this form is notified on paper)
Date: […]
9. Guarantee and lack of conformity
We are responsible for the eSIM working as agreed. If it does not work for reasons beyond your control, such as an error in the profile or in its activation, contact us as soon as you notice. Depending on the case, we will provide a technical fix or a replacement eSIM and, if that is not possible, you will be entitled to a proportionate price reduction or to terminate the contract with the corresponding refund, in accordance with the TRLGDCU.
It is not a lack of conformity if the eSIM does not work because the phone is not compatible, is locked to its network, data roaming has not been turned on, or the profile has been deleted after installation.
10. Liability
Glowi is not liable for damage arising from interruptions or coverage limitations of the local networks, from force majeure, or from use of the service that breaches these terms. This limitation does not affect the rights that the law grants to consumers or liability for wilful misconduct or gross negligence.
11. Customer service and complaints
You can send any question, complaint or claim to hello@glowisim.com, stating your order reference. We will reply as soon as possible and always within the legal time limits. If you ask for them, we will provide you with the official complaint forms (hojas oficiales de quejas y reclamaciones).
If you are not satisfied with our response, you can turn to the consumer affairs services of your autonomous community (regional government) or your local municipal consumer information office (OMIC).
12. Changes to these terms
We may change these terms at any time. Each purchase is governed by the terms in force on the date it was made.
13. Applicable law and jurisdiction
These terms are governed by Spanish law. If any clause is declared void, the rest will remain valid. If you are a consumer, the courts of your place of residence will have jurisdiction over any dispute.
