For many years I was a director of a small company, albeit the UK arm of a multinational company, and among my responsibilities was IT which included communication systems, not that I was an expert on either.
We had 7 - 8 employees with company mobiles.
Our per-requisite included:
- All mobiles be included on a single invoices which listed call costs for each phone.
- Itemized billing for each phone so we could keep a track of private v business use and demonstrate for tax purposes they were a business tool not a taxable perk.
- guaranteed Network reliability and availability.
- Ease of contact of customer services and speedy resolution to problems.
With staff traveling in Europe, US and Asia we needed to be able to make a single call to have problems quickly resolved, not post upon a forum or to an agent and wait up to 24 hours for a response.
For many years we used a Vodafone business product, it may not have been the cheapest product available but for ease of use and reliability it was worth every penny as it required so little management time to administer.
Just my experience, to me GiffGaff simply isn't a serious business product in its present form.
