From all the options VOXI have got available this March on SIM only, we think this discounted £10 1‑month deal is their best. For your £10 a month, you get 80GB data alongside unlimited minutes and texts:
While it's good enough to be in our pick of VOXI's best SIM only deals, other providers do still have similar plans for less, even ones that also use the Vodafone network. See lower-priced networks' deals here:
We also like their £12 for 100GB plan

To get a bigger data allowance, we also think this discounted £12 VOXI SIM is one of their best options. It comes with 100GB data, unlimited minutes and texts on a 1‑month deal:
It's definitely one of VOXI's best. But it's not market-leading. You can get a similar plan on other providers for less, even if you need your SIM to use the Vodafone network. Here are other networks you can beat it on:
Their 140GB for £15 SIM is another good option

To get an even bigger chunk of data, VOXI's discounted £15 SIM below is another of their best deals this month. For £15 a month, it offers 140GB data, unlimited minutes and texts on a 1‑month plan:
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. See the networks with cheaper plans here:
VOXI's unlimited data for £20 plan is a good option too

If you need even more data, the next best SIM only plan on VOXI in our opinion is their discounted 1‑month one below. For £35 £20 a month, you get unlimited data, plus unlimited minutes and texts:
It’s a discount of £15 a month against the full price, adding up to a £180 saving over a year.
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). Here's which other networks can beat it:

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.
