Jan 12,2024I encourage everyone to stay away from this crowd. They took 230 pounds out of my account without permission and are refusing to refund me.

May 19,2023This 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.

Sep 23,2021Easy 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.

Jun 30,2021So 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?

May 20,2021I 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! 😁

Apr 21,2021At 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

Mar 21,2021It 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.
