I did notice that O2 was down again this afternoon , well it was when I tried to use my phone. Looking at the news I wasn't the only one affected again http://news.sky.com/story/997091/o2-customers-hit-by-more-outage-problems. Perhaps this is just bad luck but it does make me think whether a change of provider my be wise although presumably next month I'll be enticed to remain.
I also noticed a loss of service this evening when I tried to phone my daughter (we are both on O2/Tesco Mobile). We were still able to text each other though. I'll probably stick with the same provider because I think we get a really good deal especially having two contracts which gets you some very nice perks. I pay only £20 + VAT a month for the two with virtually unlimited texts and Internet plus 360 minutes of call time.
Everyone in the Wrexham area had no O2 yesterday afternoon. One of the women from work I was out with in town last night, said he signal came back about 8oclock I think.
