The three major mobile phone companies have decided to start a service that allows them to continue to use their mobile phone email addresses, called "carrier emails," even after switching contracts to other companies.
It is in response to a request from the government, but there is a charge for both.
The so-called "carrier mail" provided by mobile phone companies will not be available if you switch to another company, so the government has asked for a response, saying that it is one of the factors that will lead to customer retention and hinder competition. ..
In response to this, NTT DoCoMo and au's KDDI announced on the 15th that they will start a new service that allows carrier mail to be used even after switching.
Both charges are 330 yen per month including tax, and NTT DoCoMo will start the service from the 16th and KDDI will start the service from the 20th of this month.
Both can be used with online-only plans.
In addition, Softbank will start a similar service within this month for about 300 yen per month.
The three major mobile companies have already eliminated the fees charged for transfer, and it will be watched whether it will lead to further competition for fees and services.
