Silly question, do you have 4g sim card? Has it been activated?

I only mention this as I had 3 sim cards from O2 that weren't 4g, despite the fact I had a 4g contract!!

Edit. My bad, 735 is 4G not 730 D'oh!!

Re: Why does 4g not work on my Nokia lumia please

Lol the reason why you aren't getting a 4g signal is because you aren't even using a 4g phone. The Lumia 730 is 3G. The Lumia 735 is 4G
