    Hi Ken,

    I read your recommendations regularly. Generally I find the information very useful. However, I have to take issue with you on your continuing support of the 3 Network. As with many users, I found the offer of an unlimited 4G data bundle attractive. Having bought the bundle I then started using my phone. At first, all went well. I got a 4G signal every day for a week. At 12 Mbps and about 65 to 70 % appearance it is definitely not as good as the performance by EE. Given the promise of unlimited data access, this was acceptable. However, since that first week, the 4G signal has disappeared (currently three weeks).

    Contacting their office was a waste of time. They claimed that their transmitters were working. They then said that they would pass me on to their Technical Department. Having waited about five minutes, the phone call was cut off and nobody bothered to contact me. I then pursed the matter on the Internet and discovered that my problem is quite common with the 3 network.

    One explanation offered is that so many people have joined the network that 3 is unable to deliver on its somewhat inflated claim of unlimited data access. Having had such a poor experience, I no longer intend to use the 3 network. I think a caveat should be issued to users considering using this network.

    Regards

    • Hi Steven,

      This is what happened to me. I logged initially good speeds around 8-12Mbits vs 70Mbits+ with EE for the first week then it dropped to virtually nothing after I had used around 10-20Gb data.

      I moved to Three’s mobile broadband this week. Picked up the B535 router from my local store. I’m seeing around 20Mb/s to 30Mb/s average peaking up to 96Mb/s (wirelessly on my Xbox one updating) and that is with the internal aerial with the router upstairs sat on the corner of my desk.

      I get 5 bars of signal strength all day. It does however seem the bandwidth bounces up and down and certainly don’t maintain a steady top speed (like cable).

      Every time I do a speed test I get a different result but overall I’m very happy up to yet.

      I’ve ordered two flat white screw in aerials from eBay which are on route, so hopefully whilst my signal strength is good, the quality should be improved with them.

      I’ll report back my findings once they arrive.

  • Hi Ken,
    Recently posted about the Three £10 All in one offer, which we took and brought 3 x Three sim cards to use whilst in the US. After only a few days there is no credit on any of the sim cards and have certainly not used 100 minutes. We entered the code given to us on the receipt at the Three shop and used the phone on and off for a couple of days but as I say not to the extent of 100 minutes. Now in the US with no minutes or texts across three sim cards. Anyone got any ideas ?

    • Hi Ian,
      Thanks for your comment. Have you double checked that an All in One bundle has been added to your account? You can do this by visiting https://www.three.co.uk/My3Account/Login. If everything has been set up correctly, you’d see zero credit on your account and a 30-day bundle which should tell you how many minutes/texts/MB are remaining on the bundle.
      Ken
