5G Frequently asked questions

As 5G is faster than 4G, files will take less time to download but the size of the file will remain the same. 5G won’t use more mobile data to download that same file. But, if you’re thinking that you might download more, because it’s quicker to do so, you can use our data calculator to see if you will need to get a bigger data allowance with your 5G contract.

At the moment, the 5G network is slowly rolling out worldwide, with some countries adopting it faster than others – like the UK. Check back with us often to see if 5G is coming to you, or if where you’re planning on travelling is 5G-ready.

A key difference between 4G and 5G is how fast you can download or stream files over your mobile data connection. For a full run-down of the difference between the technologies, check our 4G vs. 5G article.

There’s no evidence to suggest that 5G is harmful. Last year, the International Commission for Non-Ionizing Radiation Protection (ICNIRP) published a draft review of their mobile frequency guidelines and said that none of the frequencies used by mobile communications, including 5G, required amendments to their guidelines.

Both the iPhone 12 and the iPhone 12 Pro are 5G-ready, so if you’re a fan of Apple iPhones you can now enjoy superfast 5G on Apple’s latest and greatest offering.

Unfortunately, no. A phone needs a 5G chipset and modem to connect to a 5G network. Newer phones like the Samsung Galaxy S20 FE 5G, the iPhone 12, and the iPhone 13 are 5G-ready because they have the right chipset and modem to connect.
