How to use "OCN Mobile ONE" SIM in the docomo version "iPhone 5s": Cheap SIM used on used smartphones

What is "iPhone 5s"?

　The "iPhone 5s" is an Apple smartphone that appeared as the 7th generation iPhone, with a 4 -inch 1136 x 640 pixel display Retina LCD and 8 million pixel cameras.The first fingerprint authentication sensor "Touch ID" in the series has a built -in home button.

　There are three models, 16GB / 32GB / 64GB for each storage capacity, and NTT DOCOMO, KDDI (au) and SoftBank were released in Japan.If it is a docomo version, the MVNO SIM using the docomo line can be used as it is.The size of the SIM is "nano SIM".The average price in the used market is around 44,000 yen for a 16GB model, around 47,000 yen for 32GB models, and around 55,000 yen for 64GB models (all including tax included).

What is "OCN Mobile ONE"?

　"OCN Mobile ONE" provided by NTT Communications is an MVNO service for individuals using NTT DOCOMO network.The communication speed on the specification is up to 150Mbps down.There is a voice -compatible SIM and a SIM for data communication, and the data capacity can be selected not only on a monthly basis (3 types) but also on a daily basis (two types).This time, I used a data communication -only SIM that can be used for 110m bytes a day for 900 yen (excluding tax, hereinafter).

　You can also use the "turbo function" that switches between the data remaining, the existence of the speed limit, and the contract of multiple SIMs (450 yen per month / one per month).The price is 200 yen discount on the set contract with the "OCN Hikari Service", and the audio SIM is free for the company's IP phone application "050 Plus" (monthly fee 300 yen).When using the 050 Plus or OCN cloud service "My Pocket", the "count free function" does not decrease.

Attach SIM to "iPhone 5s"

　Before installing the SIM card, turn off the main unit.The SIM slot of the iPhone 5s is on the right side of the main unit, and the SIM tray can be taken out by inserting a dedicated tool into the hole.You can use the paper clip extended.Put the nano SIM on the tray while paying attention to the direction of the notch, and insert it into the main unit.

Set APN

　To use the MVNO SIM card, you need to set up an APN to specify the connection destination.In the iPhone 5s, download and set a "configuration profile" that contains APN information from the OCN website.Note that a Wi-Fi environment for internet connection is required separately.

　After turning on the main unit and started, turn on Wi-Fi from the "Settings" on the home screen, and access the OCN support page with Safari.After downloading the configuration profile, install it according to the procedure (for iOS 8).

How fast is it?

　After installing the SIM card and setting the APN, I immediately checked how much the actual line speed was in the line speed measurement application "RBB TODAY SPEED TEST".The measurement was conducted indoors of a building in Waseda, Shinjuku, around 20:00 on weekdays (August 17).

　The result is the first time down 1.54Mbps / Up 0.40Mbps, the second is down 0.79Mbps / Up 0.40Mbps, the third time is down 0.73Mbps / 0.21Mbps, the 4th time 0.64Mbps / 0.26Mbps, the fifth time 0.45Mbps / 0.It was 27Mbps.Due to the time when the number of office workers returned home, the speed itself and the unevenness were slightly noticeable.
