Sigma Plus: ¿caja, dongle o licencia digital?

When mobile phones first appeared in the 1990s, a new niche quickly followed: mobile phone servicing. In those early days, service tools were mostly private software developed and used by select technicians. Repair shops would pack bags full of phones and bring them to those few specialists who had the tools to service them. There was almost no software marketplace yet, and access to exclusive solutions was extremely limited.

A typical service center looked more like a warehouse - rooms filled with bags of phones waiting to be repaired by skilled hands. Sometimes, phones were even shipped to other countries to be serviced by a specific technician who had a unique solution and refused to share it. Phone service software circulated among a small circle of technicians.

As the internet evolved, it brought new platforms for communication and new trading service solutions. The first commercial tools were service boxes – hardware devices that, once connected to a phone via cable, would perform specific service operations. But, there was a downside: new phone firmware versions weren’t supported by old boxes, forcing technicians to buy newer versions of boxes to be able to service newer models.

Then came the next stage of progress – service boxes that could be updated to support newer phones. Competition also grew, and various teams began offering more flexible options: time-limited subscriptions, feature-based packages, or subscriptions with a limited number of operations.

However, all physical solutions shared one major drawback – shipping delays. Customers were asking for something faster, and developers recognized the need. That’s when digital licenses emerged: a solution that could be purchased, activated, and used within minutes. No waiting, no shipping – just immediate access.

Sigma Plus has gone through all of these stages! Now it is available in both physical form (box or dongle) and as a digital license.

So, how do you choose what’s best for you? Let’s go over the main benefits and differences of each option so you can pick the one that fits your needs best.

That’s when digital licenses emerged: a solution that could be purchased, activated, and used within minutes.

Box and Dongle – Classic Tools for Professionals

Before digital licensing became available, Sigma was only offered as a physical product – either a box with cables or a dongle. Both options require a physical connection to your computer while using Sigma.

Advantages:

• Less reliance on the internet – many service operations work offline.
• Unlimited PC switching – freely move your tool from one computer to another.

Sigma Plus Box

The Sigma Box includes a smart card and several ports for connecting devices. One of the key advantages of this type of hardware is that the FTDI box is a one-size-fits-all solution - it is compatible with other smart cards too. So if you need to, you can insert smart cards from other boxes as well. Another key benefit of the box is that it comes with a full set of cables.

Sigma Plus Dongle

The Sigma Dongle offers software features identical to the box but is more compact and doesn’t come with cables. Like the box, it contains a Sigma smart card. Its small size makes it easy to carry around – no bulk in your pocket – and it’s one of the team’s bestsellers.

Should your smart card, box, or dongle get damaged or lost, the team can offer a replacement

Access Duration & Renewals

When you purchase a box or dongle, you get 1 year of software access included. After that, you can renew for 6 or 12 months at any time. Renewals are flexible – buying early just extends your active period without any overlap loss. With both a dongle and a box, you get unlimited access to the boot-loader file repository.

Shipping

Since these are physical products, shipping is required. Sigma has a well-developed global dealer network to minimize delivery time. You can also choose from various shipping options directly on the official website.

How to choose the best option for your workflow? Consider the following:
