VOXI's best SIM only plan this July in our opinion is their discounted £10, 1‑month deal below, which comes with 80GB data, plus unlimited minutes and texts for your money:
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 £12 SIM with 100GB is our next favourite this July

To satisfy bigger data needs, we'd say this is one of VOXI's best deals on SIM only this month too. It's a discounted 1‑month plan, comes with 100GB data, unlimited minutes and texts for £12 a month:
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:
We also like their £15 for 140GB plan

If you think you'll need even more data, have a look at VOXI's discounted 140GB SIM below at £15 a month, as it's another good deal. It's on a 1‑month plan and comes with 140GB data, 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 unlimited data for £20 SIM is another good option

For those needing even more data, another option for you on VOXI is their discounted 1‑month SIM below, which costs £35 £20 a month for unlimited data and comes with unlimited minutes and texts:
Stick on the deal for a whole year and that monthly saving of £15 would add up to a total discount of £180.
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:

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.
