    @O2 Thanks for replying. What happens to people who are physically located on the UK side of the Irish border (say, Belleek), but whose service will frequently ping from masts on both sides of the border?

  • MattSleight Matthew Sleight (@MattSleight) reported

    @SebDance @Iskandar64 @O2 Yeah, but it's only once you use 26gb a month. I barely use that a year, so most people shouldn't have an issue.

    @O2 Bringing back roaming charges? Congratulations, you just lost a customer.

  • lauraravenhill Laura Ravenhill (@lauraravenhill) reported

    @O2 great service-keep someone on hold for 30 minutes and then cut them off! Expert phone company who can’t operate a switchboard. Only calling to ask about all of the massive changes to my contract and the option to terminate. Decision made!

  • Jolly_Giant Ian Ansell (@Jolly_Giant) reported

    @MikeAubury @O2 Mike - they clearly state on the roaming announcement page how people can leave. Click the link they’ve shared and scroll down. Customer service simply told me I CAN use my contract allowance as NORMAL. If I go over my CONTRACT limit - i pay. Why is the webpage so wordy?

    @brettpaul2000 @SebDance @O2 Not bad ! Is Virgin Mobile following suit ?

  • MikeAubury Mike Aubury (@MikeAubury) reported

    @O2 @Jolly_Giant But this is a change, which contradicts previous O2 statements about roaming, and so we're free to cancel our contracts penalty free ?

  • Joe_DMB Joe (@Joe_DMB) reported

    @O2 @Jolly_Giant Thieves. I’ll be leaving as soon as I can. This is a terrible business decision.

  • notsramdamus notsramdamus (@notsramdamus) reported

    @O2 Rather you installed more masts in poor coverage areas! Than fancy treats! #ImproveyourNetwork

  • danieldaviscomp Daniel Davis (@danieldaviscomp) reported

    @VodafoneUK I’m sure It won’t make a difference to you, but it does for me. So, just counting the last days of my contract with you and then off I go to @EE, @O2 or other company with better service and definitely a company I could trust
