Registering for a Rakuten SIM to receive phone calls helps Vietnamese people in Japan to use their personal phones to access the network, make calls, and communicate with relatives back home. Below are important notes when registering for a Rakuten SIM.
What is the purpose of registering for a Rakuten SIM to receive phone calls?
First of all, Rakuten SIM is a popular choice among Vietnamese people living in Japan. The reason is that Rakuten SIM is a cheap type of SIM, where you only pay for the data you use without fixed monthly fees like other types of SIM cards. Additionally, Rakuten SIM has strong signal reception and stable network speed.
Thanks to registering for a Rakuten SIM to receive phone calls, you can use your personal smartphone to access the network and make calls based on the data capacity provided by the Rakuten SIM.
Although Rakuten SIM is popular among Vietnamese people in Japan, not everyone can successfully register for it. Some Vietnamese people in Japan wonder why they cannot receive signals or make calls even after purchasing and following the registration instructions for Rakuten SIM. How can you register for a Rakuten SIM to receive phone calls?
Unsuccessful registration for a Rakuten SIM may be due to the following reasons:
Due to device compatibility:
Rakuten SIM is compatible with iPhones, Android phones, iPads, and tablets, but with limitations. Fortunately, since April 2021, Rakuten Mobile has implemented Rakuten SIM setup for older iPhone models from iPhone 6s upwards, provided that the devices are updated to iOS version 14 or later.
Therefore, registering for a Rakuten SIM to receive phone calls is only possible with devices that meet the SIM installation requirements. If you want to know if your phone is compatible with Rakuten SIM, check here.
Due to network coverage:
Rakuten SIM is provided by Rakuten Mobile and uses this network's coverage. Therefore, Rakuten SIM can only be used in areas with Rakuten coverage. If you are in an area without Rakuten coverage, you will need to use AU network coverage instead.
Thus, registering for a Rakuten SIM to receive phone calls is only feasible in areas with Rakuten coverage. If you install a Rakuten SIM but are not in an area covered by Rakuten or AU, you cannot use the Rakuten SIM.
However, since June 1, 2023, Rakuten's network coverage has reached 99% of Japan, making it easier for people to register for Rakuten SIM to receive phone calls compared to before

Notes when registering for Rakuten SIM
Here are some notes to consider when registering for a Rakuten SIM to receive phone calls:
Only purchase a Rakuten SIM if you need to use over 20 GB of high-speed data.
If you use less than 10 GB, there are cheaper SIM options available, such as Mineo, IIjmio, etc.
Rakuten has the advantage that you only pay for the data you use, without fixed monthly fees, which is quite economical compared to other SIMs. However, the pricing for this SIM is still higher than some other types of SIMs like Mineo, IIjmio. You should consider according to your needs.
Check the validity of your Visa.
If your Visa is valid for less than 1 year, you are unlikely to successfully register for a Rakuten SIM. If you are applying for a phone installment plan with a Visa valid for less than 2 years, you also cannot register.
You must have a bank account or Yucho account.
Registering to purchase a Rakuten SIM requires payment through a bank account or Yucho account. Yucho is one of the preferred banks by many foreigners coming to Japan due to its popularity and extensive branch network in Japan. Almost every area where Vietnamese people work in Japan has branches of Yucho Bank.
Each person can only register for a maximum of 5 SIMs.
With its advantages, many Vietnamese people register for multiple Rakuten SIMs to use data comfortably at a low cost. However, this network limits each person to 5 SIMs. If you purchase a 6th Rakuten SIM, the network will not sell it to you. Additionally, Rakuten SIM is a type of SIM with many promotional programs, but they are only applicable when you purchase the first SIM. Buying a second SIM will incur normal charges.
You need a guarantor when registering for Rakuten SIM if you are under 20 years old.
Many young Vietnamese people studying abroad or working in Japan under the student exchange program are 18 years old upon completing high school. However, if you are under 20, you still need a guarantor when registering for Rakuten SIM. Therefore, make sure you have a trusted relative or friend in Japan before registering for Rakuten SIM.
