Manx Telecom is putting up the price of phone lines and internet for some customers on the Isle of Man.
The company will increase costs next month unless people are using MT to provide all of their fixed line, broadband and pay monthly mobile services.
Fixed line rental will go up by £3 a month from May 1st - broadband will increase by 50 pence a month.
It means people who spread their phone lines, internet provision and mobile services between providers will be hit.
However Manx Telecom says it will offer customers who have their pay monthly mobile contract on the same account as their fixed line and internet a 'multi-service discount' of £4.50.
This is against the broadband tariff and would see the total monthly bill reduce by £1 - it claims a 'large-volume' of its customers will be eligible for this discount.
MT claims the changes will allow the company to continue to invest in "people, services and infrastructure" on the Isle of Man.
