F.A.Q.'s

#dot:dot works thanks to a small WIFI emitter called a #dot, which is paired with the cell phone of the person sharing their gigabytes of mobile internet access. An account must be created on the #dot:dot application to perform this pairing: the box then creates, within a 100-meter radius of the transmitter, a 2.4 GHz WiFi that appears as "#dot:dot" in the WiFi settings of any smartphone in the vicinity. Without knowing who the source of the emission is, any user with a validated account on the #dot:dot app can connect to this #dot:dot network in return for a transaction, free or paid - at the discretion of the sharing user - carried out in the app.

Yes, if you're more of a "#doter" and want to share your unused Gigabytes of mobile internet access.
No if you're "#dotee" and want unrestricted access to the Internet, paying only for the Gigabytes you actually use, on demand.

Only the #doter needs a #dot to share their Gigabytes: a #dotee doesn't need one, they only need the #dot:dot application to benefit from the #dot:dot network
For a #doter, using the #dot offers several unique advantages:

• Anonymity of sharing and transactions: while many users are interested in sharing their Gigas of Internet access, few want to do so face-to-face. Sharing a hotspot connection requires one to communicate their password, and therefore cannot be done anonymously.
• Cybersecurity: Doing the same from just within an app his would require accessing directly to the AP software layers of the phone, which is undoable for a developer, and would trigger severe security breaches.
• Range: between 100 and 150 meters, depending on the #dot model (with or without an external antenna), far greater than the 20 to 25 meters of a connection shared directly from a smartphone, where anonymity is uncertain.

For a #doter, #dot:dot lets #doters share Gigas that would be wasted at the end of the month anyway. If these Gigas are sold, they reduce the cost of their mobile subscription.
For a #dotee, #dot:dot allows you to restrict your mobile Internet access budget to what's strictly necessary, without the pressure of a subscription that you never use up completely, or the pressure of knowing "how many Gigas you're going to need" - in other words, an "on-demand" offer that doesn't exist on the mobile Internet market today.

No, the selling price of shared Gigas is fixed at 1 Euro per Giga (in France), and this price cannot be modified in the application.
On the other hand, each #doter can choose to share their Gigas free of charge: an option in the app allows this decision to be made. In all cases, the quantity of Gigas shared remains fixed by the #doter.

The maximum throughput of a #dot is currently 15 MBps (Megabits per second). To prevent the #dots from having too low a throughput, we limit the number of #dots per #dot to 3. Knowing that you can retrieve your e-mails at as little as 1 MBps, watch a video on YouTube in SD at as little as 3 MBps and a movie on Netflix in HD at as little as 7 MBps, the speed of the #dot:dot network is sufficient for many use cases.
As the speed of a 4G or 5G connection is in the range of 50 to 150 MBps, there's usually enough throughput left on the #doter's phone for sharing to go unnoticed on their phone.

Yes, #dot:dot is designed with security in mind. Baseline, it's a network with WPA3 encryption. Being based on a Zero-Trust procedure, the #dot:dot WiFi is actually more secure than most public WiFi hotspots.
No data is shared between the #doter and the #dotee: what is shared is the #doter’s right to access the Internet, via the shared connection between the #doter’s smartphone and their #dot. A #doter never shares data – in particular personal data – with anyone connected to their #dot, and a #dotee never shares data – in particular personal data – with the #doter when connecting to their #dot.

The #doter and #dotee each identify themselves with the #dot:dot cloud to authenticate, through the #dot:dot app. The authentication procedure is such that #dot:dot is immune to the most common types of hacking like Man-in-the-Middle, unlike most public WiFi’s: for a #dotee, it is safer to connect to a #dot than to a public WiFi!
A #dotee's smartphone never "talks" to your smartphone: it uses the specific channel of your smartphone's shared connection to access the Internet, so the level of security is the same as if you were sharing your connection directly.
No, no one can "hide" behind your #dot: as you'll easily see when you create your account on the #dot:dot application, you're not asked for anything apart from your mobile number: no name, no email, no address. We have no way of knowing who you are, and we won't ask. This mobile number serves two purposes:

• It certifies that only #dot:dot registered phones can connect and carry out transactions
• It enables us to comply with the anti-terrorism law, just like any mobile operator. At the request of the police authorities, we must provide the phone number of #doter and #dotee and authorities can clearly make the difference.

The #dot device has a buffer battery that provides 24 hours of continuous use. In intermittent use, i.e. around 1 to 2 hours a day, a #dot has a battery life of around ten days. It can be easily recharged via its USB-C plug.

To become a #doter, simply purchase a #dot and create an account on the #dot:dot application, indicating the amount of data you wish to share, and your availability.

As soon as you see a #dot:dot WiFi network nearby (do not forget that #dot:dot is presently under the 2.4GHz band only for the moment! Check whether your phone natively sees such networks), you can connect to it. You'll be directed to the #dot:dot application, where you can buy the megabytes or gigabytes you need, using the money reserve of your wallet. The amount in your wallet has no time limit. The amount actually billed to you is decided when the connection is interrupted, for whatever reason, according to the number of Gigas you have actually used.

#dotees are billed at the end of the connection to your #dot, only for the amount of data they have actually consumed.
The amount billed is credited to your wallet, so you can see that your connection has actually been shared!On the 28th of each month, we draw up a statement and transfer to your bank account - usually on the 1st or 2nd of the following month - the amounts credited to your wallet since the 28th of the previous month.

You can buy a #dot on the official #dot:dot website at www.dotdot.fr. For more information, visit our website or contact our customer service department.

#dot:dot promise is valid whatever the price of 1 Gigabyte: it reduces the impact of internet connexion to your monthly budget. Indeed:

• From the seller viewpoint: whatever the price one pays for a subscription, #dot:dot holds the promise to reduce the cost of the said subscription, and (if you're a good seller!) even to generate a small profit with it = it impacts one's end of month budget
• From the buyer viewpoint: a "cheap" subscription of say 10€ a month for 20 GB will turn out to be always too expensive if the need is closer to the equivalent of 1€. With #dot:dot, the buyer will satisfy their need for a budget of 1€ at the end of the month, not 10€...
