Over one third of businesses in Ireland now provide smartphones to their employees.
Telecom regulator Comreg's Business ICT Survey 2013 also found that reliance on smartphones and laptops in Irish business has increased in the past year.
Despite changes in the way telecom services are delivered and used, 86% of all businesses still provide landlines to their employees.
Four fifths of employees have access to either fixed line or mobile broadband for corporate use and almost two thirds to a mobile phone.
Only a fifth of businesses say they are very likely to change landline provider in the next year.
According to the survey, Vodafone has increased its share of the mobile phone SME business market, from 49% to 54% over the course of the last year, while O2's market share has slipped from 37% to 28%.
Eircom remains the dominant player in the broadband market, commanding a share of 55% of all SME businesses.
Satisfaction with broadband services remains relatively high, with two thirds of businesses saying they were happy with the level of service provided by their operator.
Cost, length of contract and service speed remain the predominant driver of satisfaction levels.
Just 8% of businesses said they had a broadband speed of over 10Mbps, with over half of respondents saying they were unaware of the speed they were getting.
Just a quarter of small and medium enterprises (SMEs) said they would pay more for greater speed.
Over half of SMEs said they subscribe to a telecom bundle, with a fifth saying they had seen the cost of that bundle rise in the last year, while a third saw a drop.
Vodafone is the main provider of mobile broadband to Irish SMEs, with O2, 3 and eMobile also taking significant share of the market.
Market satisfaction with this service is low at 56%, the core issues for operators being network coverage, reliability and speed of service.
The survey results are based on 500 interviews conducted by phone between 12 and 27 March among a representative sample of telecom decision makers companies with up to 250 workers.
