I just started the free trial a few days ago. I have been looking for a good signal and have tried Tesco, O2, vodafone, 3 and now freedompop. All of them say good signal outside but variable inside. Actually all of them are virtually useless inside and VERY variable outside where I live. I have just tried EE and it is vastly superior. I want to ensure I go to the free service at the end of the trial for freedompop but cannot find that option. I expect i will have to call them and cancel as I suspect they don't want you to have the free service. Anyone found out how you can downgrade to the free service?
