You’ll recognize toll-free numbers as an 1-800 number, and in the UK there isn't a huge difference, with freephone numbers beginning 0800. While those numbers are free to call from pay phones (remember those?) and landlines, network operators charge a fee to call 0800 numbers from cell phones. They don’t come out of your included minutes, either. The UK regulator Ofcom has now announced that charges for calling 0800 numbers from cellphones will be scrapped under a new proposal.
