How fast are 5G SIM only plans?

The obvious answer is that they're faster than 4G, the more scientific answer is that 5G will be topping out at roughly 20x faster than 4G.

While testing 5G devices we were seeing speeds well into the ranges of 500Mb, a speed quite a bit faster than Virgin's fastest broadband deals - a company notorious for its blisteringly fast broadband.

What happens when I'm not in a 5G enabled area?

You've invested in a 5G phone, you've paired it with a suitably 5G enabled SIM only deal and yet, you're getting 4G speeds. Why? Well, unfortunately, 5G is not available everywhere yet and offers blips of coverage.

That means you will only be able to access 5G in specific spots, mainly in the centre of cities like London and Bristol. When you leave these areas your phone will revert back to 4G or even 3G depending on what coverage is available.

It is well worth checking what coverage is available before investing in a 5G SIM only deal.
