Out of the best SIM only plans on VOXI this July, we think the leading deal is their discounted 1‑month 80GB for £10 one below, which also comes with unlimited minutes and texts:
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:
Their 8GB for £8 SIM is another good option

If you wouldn't get through that much data, another option for you on VOXI is their discounted 1‑month SIM below, which costs £8 a month for 8GB data and comes with unlimited minutes and texts:
It might be one of VOXI's best deals on SIM only but you can get a lower price for a similar plan on other providers, even ones that use the Vodafone network. Here's which other networks can beat it:
VOXI's 75GB for £12 plan is a good option too

To get a bigger data allowance, VOXI have got a discounted £12 deal on SIM only we think's worth looking at. It gets you 75GB data, unlimited minutes and texts and it's a 1‑month plan:
This is good for VOXI but it's not an unbeatable price. You can get similar SIM only plans for less with some other providers, even ones that also use the Vodafone network. See where you can get it for less here:
Their £20 for 300GB plan is a decent deal for July

To get an even bigger chunk of data, we think this discounted 300GB 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 £20 a month:
It's a good deal by VOXI'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 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.
