Orange
(since 2005)
They were uploaded to Chomikuj.pl mostly between 2009 and 2012.

Before I move to this corporation created in 1994 in the United Kingdom and, since 2000, French-owned, I want to start with PTK Centertel - the first GSM operator in Poland, because they are important in the context of how Orange entered the Polish market.
So, Centertel started providing telecommunications services in 1992 and for 4 years had a complete monopoly over GSM services in Poland. But due to not being able to keep up with more modern competitors in the form of Plus and Era, both of which started in 1996, they quickly become irrevelant... partially. In 1998 they launched a service of prepaid phone cards called Idea, which survived until rebranding in 2005. Meanwhile, in 2001, the network operator stopped accepting new customers for the services offered under the Centertel brand itself.
Two fun facts about them: Calls were transmitted using an analog signal without any encryption, so it was possible to eavesdrop on conversations. Also, their original services existed up to 2013. One of the reasons was that there were a bunch of fishermen who found that Centertel had the largest signal coverage on the Baltic Sea, so they refused to change the mobile operator.
Additionaly, my dad's first phone was the Nokia 720 (sources: 1, 2) with Centertel branding.

And now we enter the insanely complicated era of corporational turmoils between 2005 and 2013. To keep it simple, PTK Centertel as Poland's first mobile network company was co-founded in 1991 by Telekomunikacja Polska (Polish Telecommunications), aka TP, with France Télécom. In 2005, Idea were rebranded to Orange, the international branding owned by France Télécom. Meanwhile, the original Centertel services still existed in the form of a zombie in the background.
Now we enter 2012:
- PTK Centertel, owned by TP, offered Orange as mobile services only, since 2005.
- TP itself offered only landline services. But to avoid multiplying franchise stores, they keep selling both services in shops called TP i Orange (TP and Orange).
- Then TP announced they were renaming themselves to Orange... which would stay separate from the already existing Orange.
So for a year, there were two completely separate Orange brands in Poland. One mobile and one landline. Then, after various corporate shuffles, in 2013 everything finally became one, unified Orange Polska, which also finally killed the Centertel services for good. Additionally, France Télécom also renamed itself to Orange SA in the same year.

In 2010, TP launched an ad campaign that not just survived their rebranding into Orange two years later but also become the most famous ad series in the history of the Polish market. Serce i Rozum (Heart and Mind/Reason) were a two stuffed toy roommates. Serce was an anthropomorphic heart acting on its emotions, and Rozum was an anthropomorphic brain with glasses who guides himself with logic. The campaign slogan was Czy kierujesz się sercem czy rozumem, oferta TP jest dla ciebie (Whether you follow your heart or your mind, TP's offer is for you). From 2012 to at least 2019 (so three years after the campaign ended), their Facebook page was the most followed in Poland, with 1.6 million followers. There is even an English Wikipedia's page about them.


In 2011, the time from which these wallpapers are, their slogan was Dziś zmienia się z Orange (Today changes with Orange).
The standard set of the provider's startup and shutdown screens, available in three resolutions: 128x160px, 176x220px, and 240x320px.
Orange was the first brand which introduced fiber-optic internet to Poland in 2015. These wallpapers are older than that, but the company's initial tests with that technology started in 2006 in France. I didn't find direct proof for that, but I can't help but connect these dynamic light lines with optical fiber technology, which is based on transmitting light. Even if we're talking about the wallpapers for mobile devices, to which you don't connect any fiber cables.


The animated wallpaper with a roller coaster, available in the same three resolutions as the images above. Again, looking on them, I can't help but think that they used it to represent fast data transmission, but again, it could just be my interpretation.
