Why are there so many prefixes in call rates?
In general telephony, there are various categories - landline, mobiles, premium, toll-free...... Further, in many countries there are sub groups like Landlines in metro cities, landlines in cities, landlines in remote places, Mobile Network 1, Mobile Network 2. Each of these groups, subgroups are billed separately. By giving you an extensive list of prefixes we make sure that your calls are billed at the lowest price allowing you to save more on calling costs.
If we reduce the number of prefixes, your calling costs will be higher even when you dial to the network with a lower price.
