Moto G 4G - What sim would work for 4G?

[Sam Stonebridge]

I am currently on Vodafone and when I switch to Data it says H+ When it should be LTE/4G. So I researched and found that it might be the sim. So I want to know what 4G Sim from the mobile networks would work.

Vodaphone? That's a UK wireless carrier, no? I thought the G's LTE was U.S. LTE bands, only?

The G uses a micro-SIM.
