When Computer Weekly contacted EE, a spokeswoman said it had no further information at the moment and would update us if anything became available.
EE has 27 million subscribers, making it the largest operator in the UK, and was the first to bring 4G connectivity to the market.
It recently confirmed more towns able to get the faster data speeds – Ashby-de-la-Zouch, Beaconsfield, Blackburn, Burton upon Trent, Coalville, Chester-le-Street, Fleet, Gerrards Cross, Halifax, Hinckley, Houghton-le-Spring and Reigate – bringing its coverage to over 60% of the UK population.
UPDATE: A spokeswoman from EE has sent a statement explaining today's outages, but the company has still yet to explain the reports from over the weekend.
It read: “From around 7am this morning, some customers on the EE network experienced problems when trying to access the internet. This was caused by a short term connectivity issue with a network component."
"Service resumed from 10.30am, and customers were able to initiate and maintain data sessions once again. We apologise for the inconvenience caused during this time.”
