Unlike regular carriers who can receive consistent services at the shop, in the case of MVNOs that provide cheap SIMs, you have to set them yourself.I will touch it after the next time, but there are many cases where the terminal cannot be purchased as a set.The general flow is to obtain the terminal yourself, set the SIM card, and make the necessary settings.This time, I would like to look at the basics of the SIM card to how to connect to the Internet.

First, there are three types of SIM card issued by the current MVNO by size.You can buy a standard SIM (also called miniSIM), microSIM, and nanosim for three sizes that match the terminal.In this, information to identify the contractor is stored.This is the same as a carrier (MNO) on the side of the line, such as docomo, KDDI, and SoftBank Mobile.If the size is different from the SIM card slot of the terminal, you will not be able to use it.If you change the terminal and change the size of the required SIM card, you have a way to exchange it for your career.In this case, a fee is often charged.
SIMカードには複数のサイズがある。現在主に使われているのはこの3種類Why SMS -compatible SIM should be selected
SMS非対応のデータ通信専用SIMカードをiPhone 5sに挿したところ。偶然LTEはつかんだが、アンテナマークは圏外と同等になっているWhen using LTE, which is a high -speed communication standard, with a SIM card dedicated to data communication, I would like to select SMS compatible.SMS stands for short message services, which is not directly related to LTE.However, there are many cases where the terminal side, especially smartphones, which are prerequisite for telephone use, do not assume SIM cards that can only data communication.For this reason, there are problems such as not being able to communicate with LTE with SMS -compatible SIM cards, or an antenna mark is not displayed.
Although it is difficult for general users to understand the circumstances, MVNO has a strong aspect of dealing with such specifications that MVNO has SMS compatible with data communication.Of course, if SMS is compatible, services such as LINE that use phone numbers for authentication also have the advantage of being able to easily register.It is inconvenient that the antenna mark is not displayed when using a 3G terminal.There seems to be a problem that the battery consumption increases depending on the terminal.If you can choose SMS -compatible SIM cards, it's nothing better than doing so.Here, we introduced a SIM card dedicated to data communication, but since the SMS is set in the SIM card for voice calls from the beginning, the above problem does not occur.
Procedure for inserting SIM to start data communication
After obtaining an appropriate SIM card based on the above, insert it into the terminal and turn on the power.Up to this point, the flow is almost the same in MNO.Then, if most terminals remain the initial settings, they will automatically grab the radio waves.In the case of MVNOs that borrowed a docomo line, "docomo" or "NTT docomo" is often displayed on the screen.If you don't automatically catch the radio wave, try searching for radio waves.Here is Android (Android 4).Introducing procedures on the iPhone and two platforms, conforming to Nexus 5 in 4).The SIM card was used by IIJ's "IIJMIO High -speed Mobile/D Service", but the procedure is generally the same for other companies.
In the case of Android, tapping with "Settings" → "Others" → "Mobile Network" → "Communication Business", the search for the network starts.After a while, a list of communication carriers corresponding to the terminal will be displayed.If you tap "Automatically select" here, a network that matches the SIM card will be selected.In the case of a cheap SIM that uses a docomo line, it leads to docomo.
「設定」→「その他」→「モバイルネットワーク」→「通信事業者」をタップし、キャリアを選択するThe procedure is almost the same on the iPhone.When you tap "Settings" → "Career", the search screen of the network is displayed.The standard is "automatic" and there is no need to change it, but if you can not connect for some reason, try this manually.The search for the network starts and the compatible network of the iPhone is displayed.However, in both cases, the carrier name does not appear in the "out -of -area" location where the company's network does not exist.The only displayed here is the network that can be connected now.
「設定」→「キャリア」でネットワークのサーチができるIf you can safely connect to the network, you just want to use it normally, but you have to take another step to connect to the Internet.In this state, the phone and SMS can be done as much as possible.It can be said that it is the stage of connecting to the minimum network as a mobile phone.In order for a mobile phone network to connect to the Internet, you must pass through the "access point".The setting item with this information is called "APN (access point name)".In the case of MNO, it is basically to provide a terminal and a line as a set, and settings are also made in advance.On the other hand, in the case of MVNO, you have to do this yourself.It takes a lot of time, but the price is cheaper.
In the case of Android, the APN settings should be made with "Settings" → "Other" → "Mobile network" → "Access Point name".Here, tap " +" and enter APN, username, and password (may not be required for username or password).After entering, select "Save" from the menu.Tap the added APN button.In addition, Nexus 5 is registered in the terminal up to the MVNO APN in advance, and all of these are displayed when docomo's SIM card is inserted.In the confirmed range, Japanese communication and IIJ appear, so if you use these two companies, you will not need to enter APN manually.
APNの画面を開き、画面上部の「＋」をタップ。APNやユーザー名、パスワードを入力して、右上のメニューから「保存」を選択する。なお、ここではIIJのSIMカードとNexus 5を使ったため、この手順を経ず、直接APNのボタンをタップするだけで通信を開始できたThe iPhone requires installation of "Profile"
A little troublesome is the iPhone.The iPhone determines the type of SIM card and automatically sets APN.Up to this point, when it comes to automatic settings, APN may not be able to be manually edited from the terminal side.This is the problem in combination with a cheap SIM, and the iPhone recognizes the MVNO SIM card as a docomo SIM card.As a result, the APN for docomo is automatically set, and it is not possible to edit.
本来は「設定」→「モバイルデータ通信」にAPNの設定欄が現れるが、ドコモのSIMカードと認識されると、それが消えてしまうIt is "profile" that solves this.The iPhone has a mechanism to read the data called profile and automatically change the internal settings.MNO uses this to automatically set up emails and Wi-Fi access points, but the profile also supports APN changes.Many MVNOs use this mechanism to publish profiles with APN settings for iPhone.If you download it and install it on your iPhone, the APN will be rewritten for MVNO.
IIJのサイトに行き、プロファイルをダウンロード。インストールの際には、パスコードの入力を求められる。これでAPNがiPhoneに設定された。iPhone単体で設定する場合、あらかじめWi-Fiに接続しておく必要があるSo far, we've been introducing the SIM card selection to the setting method, but some of you may be wondering where to get the terminal?From the next time, I would like to introduce the terminals used in MVNO cheap SIMs.
