Japan has always been a high-tech destination for all kinds of technologies and has always been able to advance these technologies way ahead of the rest of the world.
Japanese carriers used to lock their sims to just be specific to a mobile phone and the customer could not switch carriers hence damaging the chances of the rivals for a fair completion. This, however, is going to change soon.
The communications ministry of Japan has announced plans to oblige major mobile phone carriers to remove SIM locks immediately upon the request of customers. The plans were presented Friday 20th September 2019 to a meeting of a panel of experts. The ministry is aiming at amending the related guidelines by the end of the year. Under their new fee plans, KDDI Corp. and SoftBank Corp. were poised to keep SIM locks in place for 100 days after handset purchases. But they will likely be forced to review the policy. SIM locks are designed to make the smartphones of one carrier not being able to operate on the networks of others to prevent customers from switching to rivals. The carriers have also announced plans under which the prices of smartphones bought with four-year instalments will be discounted by up to 50 percent if the handsets are returned in the two years after the date of purchases. With the Oct. 1 enactment of the revised telecommunications business law, which effectively banned discounts for smartphones sold together with telecommunication services, the carriers will be able to sell the customers with these services, hence promoting sales.
The ministry currently allows 100-day SIM locks to prevent users from defaulting on their monthly instalments.
