So I will be traveling to London this summer. I went last summer as well and I bought a pre paid UK sim card from three before I left. I was able to connect with it but I never got anything better than a 1X connection. So I was able to use chat apps like whatsapp which came in handy but really couldn't do anything else. Has anyone else run into this problem? I'm sure I had my setting correct too. Almost tempted to get the over priced verizon international plan so I can at least have a decent connection.
