Is VOXI legit?
LegitYou can trust that VOXI is real: it is Vodafone's own SIM-only brand, sold without a contract, though getting set up and leaving again do not always go smoothly. A new SIM or eSIM that refuses to activate, or a payment taken after you left, can take a lot of messages to put right.
What we checked
- Launched in 2017, first for under-25s
- Part of the VodafoneThree group
- Ratings on other review websites: 3.5/5
Watch out for
- A sign-in code sent to the very SIM or eSIM you have lost, locking you out of the account.
- A payment taken after you cancelled, with the refund slow to reach your account.
- A SIM that takes days to arrive and activate while the plan's billing has already begun.
Is your new VOXI SIM still not working?
We help you write it, it gets its own public page, and you can have it sent to VOXI as a formal letter.

How do I reach VOXI customer service?
VOXI support runs mainly through the app and the live chat on voxi.co.uk, and the number we hold for VOXI is 0808-004-5205. VOXI is a UK network, so the routes and the rights described here apply in the UK. Have your mobile number, the name on the account and the date the problem started ready before you open a chat, and save or screenshot the transcript when the session ends, because chat history is awkward to retrieve later.
Chat session closed down without the matter being logged as a complaint? Ask for it to be logged formally and for a written response, and bring it here as well: we push it out to VOXI by email, social media and printed letters.
How do I cancel my VOXI plan?
VOXI plans run on a rolling monthly basis, so a cancellation is made in the VOXI app or through live chat rather than by letter. Ask for the exact date the plan ends and for confirmation in writing, because the last charge is where most cancellation disputes start. If you are moving to another network, do not cancel first: ask VOXI for a PAC code instead, so the number moves with you and the old plan closes as part of the transfer.
Charged after you cancelled? Name the cancellation date, the confirmation you were given and every charge since in your complaint: other VOXI users hit by a charge after cancelling can find your case, confirm it and say what got theirs refunded.
How do I get a PAC code from VOXI?
A PAC code is requested by texting PAC to 65075 from the VOXI number you want to move, which is the text to switch route every UK mobile provider has to offer, and the code comes back by text along with any outstanding balance. Give that code to the network you are joining and it runs the transfer, so the number leaves VOXI without you cancelling separately. If you want to leave the number behind and simply close the account, the equivalent code is a STAC.
Transfer stalled with the number still sitting at VOXI? Keep the text you sent, the time you sent it and any reference you were given: those three details are what an escalation turns on. Open a case here and we keep coaching you on what to send next and when to escalate.
How do I take a VOXI complaint to an ombudsman?
A VOXI complaint reaches an independent ombudsman once VOXI has issued a deadlock letter, or once the complaint has been open for the period set out in the UK rules, and the provider has to tell you which approved dispute scheme it belongs to. Ask for that in writing: the scheme name and the deadlock letter are what the scheme needs to open a case. These schemes handle consumers and small businesses in the UK, and the service does not replace your own evidence.
Collect the dated material first: chat transcripts, the bills showing the charge you dispute, and the dates you asked for it to be corrected. Set it out through our complaint process and we turn those notes into an effective complaint in minutes, drawing on thousands of complaint letters that actually worked.
What do people complain about most at VOXI?
So far consumers reported 1 complaint about VOXI here, too few to show a clear pattern yet. Our research shows what typically goes wrong at UK mobile networks: coverage and data speeds that vary by address, fair use limits buried in the plan terms, prices that change on a renewal date nobody flagged, number transfers and PAC codes that stall, roaming charges abroad, and support that only exists in chat.

What happens after I submit my complaint?
Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of VOXI through emails, social media, paper complaint letters and other tools at our disposal.
And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.
Can other consumers help me with my VOXI complaint?
Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with VOXI can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
