Just billed me £29 for sim I never used. 24.1.24 FURTHER UPDATE. received another email saying they would cancel, only to then receive ANOTHER email demanding £29. Who are this unprofessional bunch!

I encourage everyone to stay away from this crowd. They took 230 pounds out of my account without permission and are refusing to refund me.

Bully you into paying when it's not a contract run away from this network as fast as u can changing networks immediately scammers

Best mobile company I've been with . Service all over has been professional and I'd never consider going elsewhere

This is a great company offering a great value SIM. Much cheaper than going to Vodafone directly. Also just want to say how fantastic Marianne is. A very helpful person who answered all my questions. I highly recommend this company for your SIM needs.

It was really easy to apply for . I received my o2 sim in two days.

Just think service is quite slow

Great, personal service. I'm very impressed with this provider.

Very good service and products. Technical support is first class.

Easy to contact via Online Chat with prompt response and product knowledge. Excellent idea to provide callers with an email copy of the ‘Chat’! Now just awaiting arrival of my SIM to activate.

Good service from Customer service colleague Ms. Marianne & fastest sent me SIM card. Will recommend to other people.

Well received the Onecall sim cards and special thanks to their staff Miss. Marianne w/200% services over standard to us.

So bad. They make you an account without giving you a username. When you click reset password you need to enter your username and not your email. How we meant it reset if we don’t know the username?

I recently switched from EE to O2 via OneCall. The customer service provided to me by Marie-Anne and Mark was stellar. There was one minor hiccup during the initial stages with setting up WiFi calling and 4G calling/VoLTE, but this was quickly resolved by the team. As for the coverage, the O2 signal is definitely better indoors than EE, but EE’s speed is faster. That being said, O2’s speed and coverage has proven to be more consistent, it is and usable wherever I’ve been. For £24 a month for unlimited everything (fair use for data is 1TB I think), you can’t go wrong. Sorry I’ve kept having to pester you guys with calls, but you’ve won yourselves a happy customer! 😁

At last I have found a vodafone service provider on a pay as you go that includes WiFi calling. Excellent value for money too without the need of long expensive contracts

It isn’t unlimited data, there is a fair usage cap at 1 Terabyte to identify commercial use. This isn’t acceptable. It’s possible to use a lot more than a terabyte and still use the services in line with both operators’ acceptable use policy. They claim that the main operators operate the same fair usage cap, this isn’t true. Both Vodafone and O2 have truly unlimited data. However, O2 does mention that if you use over 650GB of data, they reserve the right to investigate usage. However, if you use the services in line with their acceptable use policy, there is no problem. Hence there isn’t a cap present. Vodafone do not have this policy. OneCall also claim you have access to Vodafone and O2 perks, however I don’t think this is true as I did try to access Vodafone VeryMe but had no success. If you would like unlimited data, I advise you to choose the main operator of each network. At the moment, Vodafone are the only network to offer unlimited data on prepaid with their VOXI service.

Very fast and efficient service with good customer service and support. Great deals on the SIM Only 30 day rolling. Great speeds and unlimited data. Would definitely recommend

Getting 35mb download in remote Presteigne Powys Excellent support via live Chat or email support Try it you won’t be disappointed
