Shares in BT Group PLC (LSE:BT.A) and Vodafone Vodafone Group PLC (LSE:VOD) have yet to benefit much from the big price rises pushed through by the pair last week.
Vodafone followed rival BT, seemingly the UK price leader, and put mobile prices by about three times the current rate of inflation starting from 10 April.
BT said that its prices would go up £3 a month on average or consumer price inflation (2.5%) in January plus the 3.9% additional levy that all the telcos add, though why the sector gets this extra bump remains unclear.
Vodafone customers who joined or upgraded on or after July 2, 2024, will also pay an extra £3 a month from April under the new Ofcom rules that mean price rises have to be shown in pounds and pence.
Mobile phone prices rise by either £1 a month or £1.80 a month, depending on the contract.
So, for a customer before July 1, 2024, the average increase is 6.4%.
Since the start of the year, shares in BT have eased to 142p, while Vodafone has edged up to 69.5p.
