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.
