Customer Reviews

Not as good as I anticipated

I love the ‘all you can eat ‘ data which to be honest is the only reason I joined Three. Reception is patchy- ok at the front of my house, poor at the back (small end of terrace, no mansion), the voicemail service is horrendous. It rarely tells me that I have a message until 3 days later then I have to ring different numbers to actually listen to them. The only good thing is that the new app shows how much data/minutes etc. that I use each month. With that information I’m off to EE now. Bye.


This app is fine when it works but much of the time when I’m trying to find out my PAYG balance it will not update. I have been trying to get my balance for three days now and it keeps giving the same message “Unable to update. Try again later.” And that is whilst being connected to their 4G service. Ridiculously, it is not possible to check your balance, top up your phone or do anything else when on WiFi. This is not a recent problem but has been going on for years. The service really is rubbish.


Same as some other reviewers - “something has gone funny” message since Sept 29th 2017. iPhone 7. Restarted/reinstalled etc. Auto update of app is on. Rang customer services, they logged problem and did admit they are having some problems. Still not fixed Oct 24th 2017.

Note. Balance can be checked by calling 444. Haven’t had to top up yet, assume I have to ring customer services on 333?

App has always been a bit poor but over the last few months it has been improving, its a pity it has now been let down by not working at all. Not good.
