I’m with EE and until recently always got a signal up in Minera until EE went onto 4G. Now I get text messages OK, but if anyone phones me, it goes straight through to answer phone. I suspect EE wants everyone to convert to the new 4G at a higher tariff. At the moment I wont change network as EE range out in the sticks is better than O2 (I know coz my partner is on O2 ). I suggest one or more of the Network companies need to put more booster masts up.
