Since 3 merged with O2, I am having continuous issues. Randomly I don't receive texts, or receive a whole load of them at once late in the evening which people had sent during the day. The same applies to my emails - I'm not getting random emails on 3G, it's only when I hit a wifi spot that I get the emails I had missed. Thirdly the 3G signal seems to have gotten far weaker - I'm unable to access apps; search the Internet or even send emails most of the time. What's going on?
