Cellular network - 5 Bars

AT&T, Vodafone, Verizon ect are all competitors but they have two things in common - their high price (I know it hurts your pocket too!) and a great logo.

When designing for a cellular network, it should be made such that it is visible on every platform. Hence no minute details, more work on visibility and self-advertisement of the logo.

5 Bars logo shows the customer that it is the number one cellular network automatically. You don't need to read an advert for it.
