Etisalat, which has been in business since 1976, is a state-owned telecom company with the largest and most comprehensive national coverage. Du, launched in 2007, is also a government-owned business that targets the budget-conscious segment of the market with a number of discounts. Both offer land line, pay-as-you-go and post-pay mobile plans along with other phone options for users. SIM cards are available at any of the du or etisalat dealers in the UAE.
