Technically, PlusNet are OK but their call handling methods leave a lot to be desired, as it took 5 months to cancel their SIM only service, even though they emailed a confirmation and the SIM stopped working. When I realised the Direct Debit had been increased rather than ceased, today's telephone call took 1 hour and 36 seconds to resolve with the first 3 operators (Erin, Nasa & Lauren) determined to prove it was my fault. Their supervisor, Paul, finally stepped in and said the service will be cancelled in 2 hours, as I last used the device 4 months and the mobile number no longer works anyway. Would I recommend you use them? Probably not.
