I joined Tesco Mobile in January and was informed there wouldn’t be much of a signal at my home address but the mast was being worked on and the signal would be boosted within a couple of weeks. I went in the shop three weeks ago to complain and was again told the mast was being worked on. Then I received an email telling me that I would no longer be able to get BT Openzone or Hotspots. Seems to me that the service is useless and I wish to be released from my SIM only contract.
