New unlimited 5G data plans available now

Vodafone unlimited data SIMs

See unlimited plans

(opens in new window)

Vodafone have just launched a range of 5G-ready SIM only plans with unlimited data that we think are going to be very popular.

Some of them do have speed caps built in that mean you'll only get mediocre 4G speeds. But this deal gets you 5G and 4G at Vodafone's top possible speeds:

You'll need a 5G-ready phone and be in an area with 5G coverage. If you have neither, you'll still get 4G at Vodafone's top speeds.

The unlimited plans have also launched on a range of Vodafone's phone contracts too (see the models here on their website).

No headline offers so far this month

VOXI's best value SIM

How it works

(opens in new window)

There aren't any headline offers from VOXI this month on their SIM only plans or phone contracts. You can only get their standard range of plans

The closest thing to a special offer currently available is their refer-a-friend scheme that gets you and a friend a £10 voucher for getting them to join VOXI.

It works by sharing a tracked link for your friend to follow. Here's how the process works in full.
