We think VOXI's best value option on SIM only this April is their discounted £10 a month plan below, which comes with 80GB data, plus unlimited minutes and texts on a 1‑month deal:
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 100GB for £12 plan is a good option too
just
£12

For those needing more data, we think this discounted 100GB 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 £12 a month:
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:
Their £15 for 140GB plan is a decent deal for April

To get an even bigger data allowance, we also think this discounted £15 VOXI SIM is one of their best options. It comes with 140GB data, unlimited minutes and texts on a 1‑month deal:
It does enough to get into our pick of VOXI's best SIMs but that doesn't mean it's unbeatable on price. Other providers (even ones that use the Vodafone network) can beat it. Here are other networks you can beat it on:
They're also offering unlimited data for £20 on SIM only currently

To get an even bigger chunk of data, VOXI's discounted £35 £20 SIM below is another of their best deals this month. For £20 a month, it offers unlimited data, unlimited minutes and texts on a 1‑month plan:
That £15 monthly saving vs full price will save you £180 in total over the course of a year.
Compared to VOXI's other deals, this comes out among the best. But it's worth knowing you can get a lower price elsewhere, even on other providers that use the Vodafone network. See the networks with cheaper plans 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.
