The author of this blog is a current Rakuten employee. In this blog, I will share my honest impressions of my mobile phone charges and signal conditions after switching from SoftBank, which I had been using since my student days, to Rakuten Mobile. I will share information on switching mobile phones (MNP), re-contracting, comparing mobile phones, mobile phone charges, model changes, campaigns, family discounts, and special offers. Currently, the employee referral campaign allows you to earn 14,000 points if you switch (MNP) and 7,000 points if you do not switch. Those who are re-contracting can also apply. Please make use of this opportunity to switch your smartphone or sign up for a new smartphone contract.
