People are being urged to shop around on digital mobile networks, as all the major players have announced price increases.
Three Ireland is brining in an annual increase of 4.5% from next April, while Vodafone had previously said an 'annual price adjustment' meant customers would see a 3% hike on their bill from July.
And eir announced a price increase of €6 a month in September for some broadband and voice customers - an average price increase of 8%.
Eir says this increase, originally due in 2020, was postponed due to the pandemic.
Newstalk's technology correspondent Jess Kelly told Breakfast people should examine what they are getting for their money.
"Three Ireland was the latest one to confirm that, from April of next year, the prices will go up 4.5% next April and then every April thereafter.
"If you're paying €35 a month, that bill will then go up to €36.58 next April and continue to increase over time.
"So it's not just your mobile plan, it's also if you have mobile broadband - so I do think it's time for people to sit up, pay attention.
"Look at what you're paying, look at the service that you're getting and then maybe shop around".
She says the digital mobile networks can offer considerably cheaper plans.
"The ones I would look at would be the digital mobile networks - so things like GoMo, Clear Mobile, 48 - they're all associated with the big, main networks but the key difference is they're considerably cheaper.
"So, for example, you could sign up to Clear Mobile now for €14.99 a month - you could get calls, texts and data.
"The data is capped at a slightly slower speed, but for the majority of people if you're not using your mobile phone to download massive files... €14.99 versus €40 plus a 4% increase over the coming years could absolutely be worth the while.
"You need to check the terms and conditions of your contract - once you are out of contract, then you can move around".
