Best 5G SIM deals in November 2020

What are 5G SIMs?

In most cases, a 5G SIM is a physical SIM card that you insert in your phone and which gets you a 5G mobile internet connection.

All you have to do is put it in a 5G-compatible smartphone and you’re good to go, with 5G speeds that are up to 20 times faster than 4G.

5G SIMs are also available as e-SIMs. With 5G e-SIMs, there’s no physical SIM card that you have to insert. Instead an eSIM is a small chip that comes embedded in your handset when you buy it.

5G SIMs are available from:

• O2
• Sky Mobile
