GSM (Global System for Mobile Communications, originally Groupe Spécial Mobile), is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile phones, first deployed in Finland in July 1991.As of 2014 it has become the default global standard for mobile communications - with over 90% market share, operating in over 219 countries and territories.
2G networks developed as a replacement for first generation (1G) analog cellular networks, and the GSM standard originally described a digital, circuit-switched network optimized for full duplex voice telephony. This expanded over time to include data communications, first by circuit-switched transport, then by packet data transport via GPRS (General Packet Radio Services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS).
Subsequently, the 3GPP developed third-generation (3G) UMTS standards followed by fourth-generation (4G) LTE Advanced standards, which do not form part of the ETSI GSM standard.

You see inside
You see inside
You read my mind
You read my mind
You survived a hellish dream
Now the light can mend the seams
But your will wraps tight around
Watch the sky come crashing down
You breathe
Believe
You touch
Won't face I need you so much
Embrace
Encase
I fear
Your love for me is so clear
You survived a hellish dream
Now the light can mend the seams
But your will wraps tight around
Watch the sky come crashing down
I arrived on foreign land
With no one to hold my hand
But my guide came shining through
From the fog alone stood you
A love that's so defined
You'll never wake the newness that can be
A happiness so kind
Mistaken for seductive falsity
You breathe
Believe
You touch
Won't face I need you so much
Embrace
Encase
I fear
Your love for me is so clear
A love that's so defined
You'll never wake the newness that can be
A happiness so kind
Mistaken for seductive falsity
Just knowing that you're mine
Erases all reverse complexity
The emptiness unwinds
An unexpected flexibility
You survived a hellish dream
Now the light can mend the seams
But your will wraps tight around
