...can't make calls, send texts or use data? This is annoying as this signal is overriding my weak 3G/4G signal.
I have a Samsung J5 for the record.

Thanks

If I set my ZTE Blade to LTE only, I get signal as well. Bars on the screen and everything but it vanishes as soon as you try to do anything. It's obviously not being blocked by all handsets.

You need an update from Three for it to work.

Your best bet is to disable 4G in your settings so it's 3G only, then give 333 a call.

The point is if that your phone can't use it anyway, you don't want the phone latching onto it at the expense of 3G/4G1800 as, well, you can't use it.
