    @O2 don’t ever get a contract with O2, the amount of times I have complained about 5G internet and no one has dealt with my complaint is ridiculous! Never ever would get a contract with O2 again! Worst phone company ever. My girlfriend is with EE and she always praises them!

    @O2 why can I literally not get 4G signal anywhere I go now? I live in a major city centre and I can’t remember the last time I had 4G signal. The signal I’m getting is absolutely shocking. Needs sorting ASAP or else I’m going to another network provider
