Even though it's in our pick of VOXI's best SIM only deals, you can actually beat it on price with other providers, including ones that also use the Vodafone network. Here's where else you can get a lower price:

While this is a good enough deal to make it into the best of VOXI's SIMs, you can beat it for price (even if you definitely want a provider that uses the Vodafone network). See who's offering it for less here:
Their 140GB for £15 SIM is another good option

If you think you'll need even more data, VOXI have got a discounted £15 deal on SIM only we think's worth looking at. It gets you 140GB data, unlimited minutes and texts and it's a 1‑month plan:
It's a good enough deal to get into VOXI's best SIMs but you can actually get a lower price for a similar plan elsewhere, even if you definitely want it to use the Vodafone network. Here's where you can beat it on other networks:
VOXI's unlimited data for £20 plan is a good option too

£20

For those needing even more data, we think this discounted unlimited data is one of the best SIM only plans on VOXI too. It's on a 1‑month deal, comes with unlimited minutes and texts - all for £35 £20 a month:
Stick on the deal for a whole year and that monthly saving of £15 would add up to a total discount of £180.
In comparison to the rest of VOXI's current SIM only plans, it's one of the best. But it is beatable on price, even if you're set on joining a provider that uses the Vodafone network. See lower-priced networks' deals here:

How VOXI compare for benefits and SIM only prices
In our VOXI review, we said we liked VOXI’s great mix of coverage and great data speeds via Vodafone’s network. They offer an identical network experience to being on Vodafone (read our VOXI vs Vodafone guide).
All of their SIM only plans are on 1-month deals. They don’t offer a massive range of data options, but there’s enough choice to suit most people’s data needs.
VOXI’s SIMs tend to be fairly cheap and they’re one of the cheapest ways to get onto the Vodafone network (alongside ASDA and Virgin Mobile).
They offer unlimited social media data on all plans and unlimited streaming data on most of them. And you can get extra rewards for bringing friends onto VOXI. But they don’t offer inclusive EU roaming any more.

Other handy things to know about VOXI’s SIM only plans
Your VOXI SIM will arrive between 2-4 working days. The package you receive will contain each size of SIM card, so you can fit your SIM into any phone. VOXI don’t yet offer eSIMs (see the networks that do here).
If you’re unhappy with your SIM you can return it within 14 days. You’ll have to pay for whatever you used up to that point, so you may not get a full refund if you used some data (read full details here).
All VOXI’s SIMs are paid for up front, so you don’t need to pass a credit check to join them on SIM only. But you will have to give some identification details just to let them know who you are.
To keep your number when switching to VOXI from another provider you’ll have to request a PAC from your old provider and give it to VOXI at any time. Here’s their guide on how to do this.
