In the telecommunication network, each user must have a set of dynamic data to mark user attributes, tariff, etc. This set of data is stored in the local server. When the user calls in a different place, the local network must transfer this set of data from the user's source to provide services, The network element equipment required in this retrieval process is the basic cost of roaming fee. All construction costs of telecom network must be taken back from the tariff. If the roaming fee caused by unbalanced regional economic development is cancelled, all costs can only be shared equally among the whole network, that is, each user in the country, That is, users who do not need to roam should subsidize part of the fees for roaming users. As a result, it is found that the original cheap local calls are more expensive, and the more economically underdeveloped areas, the greater the increase.
intended to express that:
You need to think twice before canceling the roaming fee
