British mobile network operators EE and O2 announced that they\u2019ve resolved network problems preventing users from making and receiving calls.\r\n\r\nThe two mobile phone giants (boasting a combined 50 million customers) received a flood of complaints from customers that their calls were not connecting.\r\n\r\nEE and O2 have now said that customers who were affected by the glitch should now be able to make calls without any problems.\r\n\r\nThe two firms said the issue was caused as a result of a glitch in the fixed line network managed by BT.\r\nThe two firms blamed BT, which manages the fixed line network.\r\nA statement on O2's network checker page said:\r\n\r\n"We are aware of an issue where some O2 customers may be experiencing difficulties making calls from their mobile to EE mobiles and to landline numbers. BT, our fixed line partner, have confirmed they are investigating a problem within their network and we apologise for any inconvenience,"\r\n\r\n\r\n\r\nThe company later said: "This issue should be resolved now. It was an issue with BT, our call routing partner who resolved this as quickly as they could."\r\n\r\nMany consumers in the UK vented their frustration on social media:\r\n\r\n\r\n#RushHourBiz Anyone suffering as #EE admit major failure in network this evening?\r\n\u2014 MineralDoc (@MineralDoc) January 11, 2016\r\n\r\n\r\n\r\n#ee having a major issue is causing my day to be a lot more difficult\r\n\r\n\u2014 Lee-Anne (@GeekyLeigh82) January 11, 2016\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nAn EE spokesperson posted the following tweet:\r\n\r\n\u201cWe're aware customers from EE (and other networks) are having issues calling landlines.
