Compared to just a year ago, the number of 5G phones available on the market have sky-rocketed. Especially with last month's launch of the Samsung Galaxy S20 range phones – all of which are available with 5G connectivity.

5G promises up to 20 times the speed of regular 4G networks, which translates to 4K mobile streaming, faster video loading and smooth mobile gaming.

You would need a 5G SIM to use a 5G phone, so in most cases buying a 5G phone on contract may make more sense unless you prefer paying for the phone fully upfront and buying the SIM separately. Here we've gathered the best 5G phone contract deals in the UK

Keep in mind 5G phones operate with a separate 5G modem inside, which means 5G phones can handle 4G networks and below, but 4G phones cannot handle 5G networks. For more about 5G see our explainer What is 5G?

Where to find 5G phone deals in March 2020

You can find 5G phones from most major phone retailers and networks (though not all). Now that Samsung has launched three new Galaxy S20 phones – all of which have 5G connectivity – we expect 5G phone deals to become even more competitive.

A top deal now on the S20 Plus with O2 offers 160GB data for £48 per month without any upfront costs. You can also claim a free pair of Galaxy Buds+ earphones.

Meanwhile the Galaxy A90 5G has £180 off directly from Samsung. Alternatively, if you pick it up from Mobiles.co.uk you can get a free pair of Beats EP On-Ear headphones, a £50 Love2Shop High Street voucher, or a free Amazon Fire 7 tablet. See all 5G phone deals from Mobiles.
