Vodafone's best SIM only deals

It's a good deal by Vodafone's standards but price-wise you can still beat this plan on other providers (even ones that still use the Vodafone network). Here are the networks offering it cheaper:

How Vodafone’s SIM only prices and benefits compare
As we said in our full review of the Vodafone network, we rate them highly for their fast 4G and 5G speeds and their great overall mix of coverage.
They offer SIM only deals on 1-month, 12-month and 24-month contracts. Generally the longer your contract the less you pay per month, but it’s worth comparing to get the best current overall deal.
Vodafone are one of the more expensive UK networks, and their smaller data plans aren’t very well priced. Their larger data plans are much better value, especially their 24-month deals.
A lot of their benefits are restricted to premium plans. You can get inclusive EU roaming and even inclusive worldwide roaming on certain plans. They also have pricier Entertainment plans that give you subscriptions to entertainment services.
