Frequently Asked Questions

It’s very simple! You can download our mobile app to do it or via our website by selecting the subscription of your choice.

1. You must first log in with ITSME to create your account.

2. Then follow the order steps until it is finalized.

3. You will receive an email confirmation of your order.

If you order an eSIM, you will receive a second email with the QR code of your eSIM in order to install it on your smartphone. The activation of your number with an eSIM is generally active within the hour and you can start using it immediately, unless you have made a request for a number transfer. In that case, the delay mainly depends on your current operator!

When ordering, you will need to provide us with all the required information from your previous operator and we will take care of the number transfer. Make sure you fill out all fields accurately for a quick and smooth number transfer. Otherwise your previous operator will simply refuse the transfer of your number.

UNDO uses the Orange network. There is nothing more annoying than a video that won’t load. Our SIM cards are equipped for 5G, both the eSIM and the traditional SIM card. Therefore, our users can rely on a strong and fast network everywhere in Belgium.

You can order up to 7 SIM cards as a private user and up to 25 SIM cards as a business.

During your order you can simply choose for an eSIM or a classic SIM card.
In case of an eSIM, you will need to select the brand of your smartphone and then the model of your smartphone in order to know whether or not your smartphone is compatible with the eSIM. If this is the case, we strongly recommend that you opt for an eSIM for which the carbon footprint is practically zero compared to a traditional SIM card.

An eSIM is a digital SIM card, which replaces a traditional physical SIM card. At UNDO, you don’t pay any costs for this type of SIM card. With an eSIM you can start surfing, calling and sending SMS in the minutes following your order because it activates much faster than a physical SIM card.
Note: not all phones support an eSIM. Smartphones that do this also offer space for a physical SIM card. With such a Dual SIM smartphone, you kill two birds with one stone. You can use two numbers, and therefore two subscriptions. Compared to a traditional physical SIM card, an eSIM has many advantages:
– Activation is digital so you have no waiting time
– You choose a more environmentally friendly alternative, without plastic.
– You can easily switch from one number to another if you have a Dual SIM smartphone. So you decide, for example, which number you call with and which number you surf with.
– Outside the EU you can easily use a local SIM card.
– Lost or stolen smartphone? Activate a new eSIM in 1-2-3 in your replacement device.
– No need to change physical SIM cards anymore.

Once you’ve ordered an eSIM you’ll receive an email with the detailed installation procedure.
Is this eSIM for another person? Then forward this email to the relevant person so it can be installed on his/her smartphone.

Follow these steps for the eSIM installation:
– Scan the QR-code in the email with the camera of your smartphone
– Follow the steps and unblock your eSIM with the PIN-code received in the email

Please note that after scanning the QR-code and installing the profile you will receive a SMS once your eSIM is active.

Important: DON’T delete the installed eSIM from your smartphone because you can only install the QR-code once!

Pay attention: if the installation with the above steps fails you can also activate it manually:
– For Apple : go to “Settings” – “Cellular” – “Add Cellular Plan” – “Use QR-code” and complete the steps
– For Android :
1. Go to “Settings” – “Connections”
2. Tap on “SIM card manager”
3. Select “Add mobile plan”
4. Navigate to “Other ways to add plans”
5. Choose “Add using QR code”
6. Scan the provided QR code
7. Follow on-screen prompts

Please follow the steps below if your eSIM is not working:
– Make sure that the eSIM is active and unlocked with the PIN code in your smartphone’s settings (you can find the PIN code in the email with the QR code you received for installation).
– If you still have an (old) physical SIM card in your smartphone, it is best to remove it.
– It is also best to set the UNDO eSIM as the primary SIM. If you have multiple SIM cards/eSIMs in your smartphone, the UNDO eSIM might be a secondary number. You need to set it as the primary SIM so that your calls/SMS/surfing will be done with the UNDO eSIM.

After following the above steps, restart your device to establish a new network connection.
You still don’t have network coverage with your eSIM? Then order a SIM SWAP via our Mobile APP or Customer Portal in order to receive a new eSIM (QR code) and install it on your smartphone.

Our eSIM works with most smartphones and tablets that support eSIM. Smartwatches are currently not supported. Check your device’s specifications to make sure it’s compatible.

You can transfer your current eSIM to another smartphone by ordering a SIM SWAP in our Mobile APP or Customer Portal. On your subscription, click on “MANAGE” and then choose “SWAP YOUR SIM CARD”. Select “eSIM” and follow the steps. You will receive a new QR code via email, which you can use to install your new eSIM on your other smartphone.
As soon as your new eSIM is correctly installed on your smartphone, the change will be initiated at network level which can take up to 2 hours. As soon as the change is made at network level, you will receive an SMS confirming that your new eSIM is active.

If unluckely you entered 3 times a wrong PIN code, your SIM card will be blocked. This aims to protect it from unintended usage from others.
To unblock your SIM card, you need to use your PUK code (Personal Unblocking Key).
This PUK code can be found:
– On the plastic that surrounded the classic SIM card (keep this code in a safe place and not near your smartphone)
– In the email with the QR code that you received for installing the eSIM
– In our Mobile APP or Customer Portal. Click on “MORE”, then “SETTINGS” and at the bottom right you will see your PUK code
To unblock your SIM card, you just need to follow the instructions on your smartphone with the use of your PUK code.

The standard PIN code can be found on the plastic card, which was holding your SIM card or in the email with the QR code you received for the installation of the eSIM. You preferably change it by a code you only know.
How to change your PIN code? If you want for example the code “1375” as a new PIN code, you enter **04*oldPIN*1375*1375# on your smartphone and press the dial button. The PIN code is now changed to your new code.
For security reasons, you better do not choose sequential numbers (1234) or same numbers (2222).

You can switch of the PIN code of your SIM card. You can do this in the settings of your smartphone but we advise you not to do so for security reasons.

You can change the language of your SIM card via our Mobile APP or Customer Portal. Click “MORE” and choose “SETTINGS”. Then, select the language of your choice for your SIM card. Once changed, the chosen language will be green.

You’ll find you SIM card number in our Mobile APP or Customer Portal. Click on “MORE”, then “SETTINGS” and at the bottom right you will see your NSCE (= SIM card number)
Or:
– In case of a physical SIM card: on the back of your current SIM card
– In case of an eSIM: In the email with the QR code you received for the installation of the eSIM
– In your smartphone settings:
– For iOS
1. Go to “Settings” > “General” > “About”

Your CO2 emissions are a result of using your smartphone on a daily basis. Smartphones work on various rare earth minerals such as gold, cobalt, lithium, silver, and silicon. The mining of these components releases carbon into the atmosphere. Similarly, the manufacturing of the smartphone also causes emissions. As a user of smartphones, we also rely on our 4G/5G networks to make calls, surf on internet, use various applications, and occasionally send text messages. These networks consume electricity to power up and function. Electricity often comes from non-renewable sources and causes emissions as well. Similarly, our phones need to be charged which again consumes electricity and causes emissions. All these sources combined lead to CO2 emissions that can be attributed to us as a user.

As an UNDO member, you have the chance to contribute to the fight against climate change. Planting trees is surely one of the simplest ways of helping and having a direct impact. That is why each new member joigning UNDO plants one tree by default in our UNDO Forest – a natural carbon sink. But that is not all, every UNDO member can also support emerging carbon removal technologies such as biochaar, CCS, and enhanced weathering via “UNDO Removal”. Your monthly emissions calculated via our mobile app can be neutralized by assigning the same or greater number of KGs across one or more removal projects of your choice that UNDO proposes.

The overall emissions displayed include the following:

(1) DEVICE – UNDO computes the emissions produced during the manufacturing of your device, taking into account whether your device is new or used. The data is gathered from environmental product reports issued by manufacturers like Apple, Huawei, and Fairphone.

(2) BATTERY CHARGING – UNDO estimates your daily power consumption and resulting emissions based on how much time your device spends under charge.

(3) TELECOM USAGE – The energy consumed by the network to provide you with services such as calls, text messages, and data is calculated by UNDO according to your number of calls, SMS, and GBs used.

(4) ONBOARDING & ACTIVATION – UNDO also factors in the one-time emissions resulting from the ordering, the sending as well as the activation of your UNDO SIM card. If it is a:
– Physical SIM card, this represents a total of 8,1 KG of CO2
– eSIM, this represents a total of 3,1 KG of CO2.

Just like GBs each UNDO subscription includes a certain amount KGs (Kilogrammes). Consider these as your personal emission credit that can be used to compensate your monthly emissions resulting from your smartphone use. You can find these KGs and carbon compensation projects in the “UNDO Removal” section. Just log in to the app, assign KGs to the project you like and hit “Compensate”! This allows each member to choose the project(s) that best suit them in just one click. In case your emissions are higher than the available KGs you can purchase extra KGs in the form of add-ons. You can find these add-ons by tapping on ‘SHOW ME’ in ‘Your Tariff’ section via the mobile app or web customer portal. Your KGs that remain after compensation will be carried over and added to your available quota next month.

UNDO Removal aims at connecting the UNDO community to literally carbon removal technologies! In an attempt to balance the amount of carbon released due to human activity, these technologies ensure the removal of atmospheric carbon and long-term storage for over 100 years in different forms such as demolished concrete, or underground sequestration! One of the most critical challenges of the present day faced by such technology-driven projects is the high cost of project execution, which can be lowered by applying the principle of economies of scale. UNDO procures high-quality, certified REMOVAL credits from individual project developers across the globe. Projects are verified by independent 3rd party agencies and follow internationally recognized benchmarks and reporting standards such as Gold standard, Puro earth, and Verra. For our members, UNDO removal is a way to choose projects of their choice and be carbon-neutral by compensating their emissions every month. You can use your CO2 KGs pre-included in your monthy subscription at no extra cost.

For our UNDO community, “UNDO Removal” is a way to choose the carbon offset project of your choice and be carbon neutral by offsetting your CO2 emissions each month. You can use your KG of CO2 already included in your monthly subscription for free and at no additional cost! However, if you do not have enough KG available in your subscription, you can always purchase more. Here are our complementary and optional add-ons that you can purchase:

• 2 KG CO2 – 1 €
• 5 KG CO2 – 2 €
• 10 KG CO2 – 3.50 €

You can activate them in your app or in “My account” (https://wsc.undo.be/). Under “MY TARIFF PLAN”, you can click on “SHOW ME” to activate the add-ons.

UNDO Forest is a project that aims to create a natural carbon sink that will absorb and store carbon below the ground in soil. It’s 100% owned by UNDO. The project is being developed in the Democratic Republic of CONGO, near the town of Kinshasa. We work in collaboration with our partner IBI Village, which helps us with on-ground activities. The project aims to plant 25.000 trees in its 1st phase. The concept of agroforestry is applied that ensure maximum utilization of the land and turn a dry savannah into a habitat filled with acacia, corn, and manioc. Every new subscription guarantees planting 1 tree but that is not it. Under the project, our membres can also support additional social initiatives by adding “UNDO Forest” add-ons to their monthly subscription. This way our community not only helps the planet but also helps out the local population by providing employment, and aid, much like the UN sustainable goals.

UNDO provides regular updates about the progress of the project and on ground activities via photos, videos, or even interviews of locals via our social media channels. Follow UNDO on Facebook, Instagram, Tiktok to stay updated.

UNDO Forest add-ons are initiatives that are aimed at improving the lives of the locals and helping quicken the planting of trees in our UNDO Forest.  The projects are actually picked from the list of wishes that was put together by the locals that live nearby and help us in maintaining the trees, planting new ones or even building firewalls to protect our precious forest from burning down in natural forest fires during the dry season. These initiatives directly help improve the quality of life of the locals in the form of planting more trees, providing medical aid for local families, educational support for their children, buying farming tools, or even preserving important members of the biodiversity such as bees!

You can find these add-ons by tapping on ‘SHOW ME’ in ‘Your Tariff’ section via the mobile app or web customer portal.

UNDO plants trees in Congo rather than in Belgium to make a greater environmental impact and support global sustainability goals. The Congo Basin is one of the world’s most important carbon sinks, absorbing far more carbon dioxide than forests in Belgium due to its tropical climate and fast-growing trees. By focusing reforestation efforts in this region, UNDO helps combat severe deforestation, which is a major contributor to global carbon emissions.

Additionally, restoring the Congo’s forests helps preserve biodiversity and protect endangered species. The vast areas of degraded land available in Congo also allow for large-scale tree planting, which wouldn’t be feasible in more urbanized regions like Belgium. This approach maximizes the positive impact on climate change, ecosystems, and local communities.
