Thousands of EE's longest standing customers will see their bills jump next month in a delayed price rise.
The network said those who joined the mobile provider more than five years ago will be hit with average bill hikes of 2.4% on 1 June.
Anyone who signed up to the network before January 23 2014 who hasn't taken out a new contract or upgraded since, will see their bills rise by an average of 45p a month - or £5.40 a year.
These EE customers weren't hit with the 2.7% hike that kicked in across the network in March as they weren't in contract.
Instead, EE said they will receive their price rise on 1 June at an inflation rate of 2.4%.

Am I affected?
The network, which has around 31 million customers, said it's been writing to those affected since April 23 - and the good news is if you're unhappy about it, you can do something about it.
All customers affected by EE's latest rise are out of contract - so they're free to leave penalty free if they wish to.
Alternatively, you could take the opportunity to haggle a lower deal. Often some of the best offers are reserved for new customers, so armed with your loyalty and freedom, you could negotiate a much cheaper price.
If you choose to leave, however, you will need to provide 30 days' notice from when you received correspondence from the network saying your bill is going up.
An EE spokesperson told Mirror Money: "We go further every day to provide our customers with the UK’s best mobile network and great customer service, with 4G coverage in more places than any other operator.
"Like many service providers, our Pay Monthly plans increase by RPI annually, and this June customers who joined us before 23 January 2014 will typically see an increase of 45p a month on our most popular plans. We’re currently contacting customers to remind them this will take effect from 1 June 2019."
Ru Bhikha, mobile expert at price comparison site uSwitch.com, said now is the time to dig out your paperwork and act on it.
"Those long-standing and loyal EE customers who would have thought that they had avoided an annual price hike will be getting a rude awakening with this news," Bhikha explained.
“While the figure may seem small, it will easily add up and for those one in six mobile users who are out of contract and still paying for a handset they have long since purchased, it really should spur them into action.
“If you are an EE customer who is out of contract a quick comparison could surprise at how much you can save, as well as the extra data, perks and benefits currently available."
