My problems with Onecom started when I discovered that the courier company they use to deliver SIM cards was having problems locating my house and they failed to pass on instructions to the courier company on how to find it. For the last 11 days I have been without a service on my work phone as Onecom decided to activate the SIM which was lost in transit and cut me off from my former service provider. I had to suggest that a second, replacement SIM be sent. The courier company again had problems delivering the item and I spent hours talking to Onecom. I finally spoke to the courier company and discovered that they had no record of anyone from Onecom contacting them with delivery intructions. Only my direct intervention resulted in the SIM being delivered - after 11 days. During the course of my attempts to resolve the situation, I spoke to the company who will be providing the phone service and found that the length of contract it believed I have with it is 12 months longer than the contract I have with Onecom. Despite raising this discrepancy with Onecom, I have yet to receive an answer. I would strongly recommend that anyone reading this review decides to have nothing whatsoever to do with Onecom. They are interested in making a sale but not in providing a service.
