O2 announced it is increasing prices for customers, despite calls to the industry to reverse mid-contract price rises.
Each year, certain telecoms companies adjust their tariffs by the Retail Price Index (RPI) rate of inflation.
This rate is announced in February and bills are adjusted by this amount in April.
If you're an O2 Consumer customer, RPI can impact your Pay Monthly tariff, including your O2 Refresh Airtime Plan (but not the Device Plan), your sim only tariff, standard tariff, mobile broadband tariff and smartwatch tariff.
This year's RPI was published on February 17 and was 1.4%.
So if you signed up to your current contract since January 23 2014 prices will rise by 1.4%.
EE is also increasing their mobile prices by 1.2% or 4.5% depending on when you signed up.
April and May bills from three customers will rise by either 1.5% or 4.5%.
And Vodafone customers will be hit with price hikes of up to 4.5% next month.
Tom Denyard, CEO of Tesco Mobile, said: “With this announcement, all of the MNOs will now be applying an above-inflation annual price increase.
"It’s disheartening to see that despite being one of the most uncertain financial times on record, Telecoms companies, like O2 today, have ignored our call to reconsider these rises.
“O2’s price hikes along with Three, Vodafone, BT, Sky Mobile and more, will mean less items in the shopping basket, added pressure to pay household bills, and increased difficulty to accessing the human connection that we are all relying on right now."
