Mobile phone network O2 started work this week to bring its 4G service to Craigavon as well as improving its 2G network.
The 4G network will deliver high speed mobile internet to customers in the area.
Work started on Wednesday and will resume again next Tuesday, continuing for one or two days.
A spokesperson said, “Subject to successful implementation and testing, customers will see the new and improved service shortly afterwards. During the work, there may be times when a customer’s signal experiences intermittent service.
“We recommend that customers download the TUGo app which enables them to make and receive calls on any wifi-connected device using their mobile number. More information can be found at www.o2.co.uk/apps/tu-go.”
O2 is spending £600 million in 2015 on its network and by the end of 2017 will have invested over £3billion in 4G and the modernisation of its 2G and 3G networks across the UK.
