Mobile network Three has apologised to customers this morning after a number of users received a text from the network relating to their data usage.

A number of customers received messages, such as this earlier today:

The company has issued the following statement.

"Three is aware that some of our prepay customers received a text message regarding their allowance in error this morning. We are working to resolve the issue and any necessary refunds will be processed as soon as possible. We would like to apologise for any inconvenience."

Bill pay

The network says this text message was only sent to pre-pay customers. This comes as bill pay customers are being informed about an increase of €5 to their monthly plans.

As the company is changing the terms, customers can opt out of their contract if they do not accept the proposed changes. Anyone unhappy with the €5 increase has 30 days to exit, without a penalty. This means those who purchased a phone as part of their bill plan do not have to return the device.
