You can also purchase a plan for only the period necessary for your stay and use the line at a lower cost. Another advantage of eSIM is its flexibility; if your overseas travel schedule changes, you can immediately purchase an additional plan from your terminal.</p><h3 id="h63d6041572">(2) Easy application and activation procedures</h3><p>eSIM&quot; can be activated from the terminal via the Internet. Many eSIMs can be used on the same day after the activation procedure is completed, so you can prepare your Internet environment in time even just before your overseas trip.</p><h3 id="h2437883509">(3) Same-day service is available from the local terminal</h3><p>eSIM&quot; allows you to open an eSIM terminal easily. Setup is possible even from overseas, as long as you are at an airport or other location with a WiFi environment. If you are too busy to pick up your SIM card in Japan, or if you have a sudden overseas trip, eSIM allows you to connect to the Internet anywhere with a single device.</p><h3 id="h93d090af2b">(4)No need to receive and return telecommunication equipment</h3><p>eSIM&quot; can be used simply by installing it on a terminal, so there is no need to return it like rental Wi-Fi routers or some SIM cards for overseas use. Also, since an Internet connection can be established with just a terminal, there is no need to carry a router or mobile battery for the router. This allows you to enjoy your overseas travel with less luggage.</p><h3 id="h3a681a9bf2">(5) No need to replace the SIM</h3><p>eSIM&quot; is a system that eliminates the need to replace the SIM card. There is no need for a small SIM card or SIM pin, so there is no risk of loss or damage.</p><h3 id="hb760c271ef">(6) Easy switching across countries</h3><p>With a conventional SIM card, when you move to a new country or region, you have to go to the trouble of replacing it with a corresponding SIM card. With an eSIM, however, an electronic SIM is programmed into the device, so you can use the Internet as soon as you select a country or region on the device.</p><h3 id="heedda2af36">(7) Not bound by restrictions on SIM card purchases</h3><p>In Germany, due to anti-terrorism measures, since January 2017, the Telecommunications Act has made it mandatory to verify identity and register an address when purchasing a &quot;prepaid SIM card&quot;. The advantage of &quot;eSIM&quot; is that you are not affected by such country-specific SIM card purchase regulations.</p><p></p><p>Disadvantages of eSIM</p><p>Although the eSIM has many advantages for international travelers, there are actually two important disadvantages. We will explain them in this section, so if you are considering using an eSIM, please check them out!</p><p>Local phone numbers do not work</p><p>Most eSIMs do not provide local phone numbers. Therefore, if you are sure that you need to make calls or send/receive SNS (short messages) using a local phone number, we recommend that you use the overseas calling service of your carrier in Japan or purchase a SIM card with a local phone number.</p><p>On the other hand, LINE and Instagram call functions can be used without any problems even with an overseas eSIM, so those who say, &quot;I use LINE to make calls, so I don&apos;t have to worry about it,&quot; can use an eSIM with no worries.</p><p>If your smartphone does not support eSIM, you cannot use it.</p><p>Although eSIM is rapidly becoming popular both in Japan and overseas, some smartphones are not eSIM compatible, so be sure to check in advance whether your smartphone is eSIM compatible or not.</p><p>▼ eSIM-enabled iPhone handsets</p><p></p><pre><code>・iPhoneXS, iPhoneXS Max, iPhoneXR

Inexpensive SIM cards are popular for both short-term and long-term trips, and are also popular among young people such as students traveling abroad.</p><h3 id="h3e0f4938a7">No baggage</h3><p>The SIM card is so small that it does not constitute additional baggage. The lack of bulk is a huge advantage, as there is no need for a cord to charge the battery. It is also ideal for those who prefer to travel with just a small bag. It is also recommended for people who do outdoor activities and sports, as it allows them to move around with their hands free without carrying large luggage.</p><h3 id="hfb1a04c022"><strong>Easy to sign up</strong></h3><p>It is often easy to sign up at the local airport or online.

This is a point to keep in mind. I have heard of many cases where the SIM card fell into the space between the seats when trying to replace it on an airplane and could not be removed. When replacing the SIM card, be sure to do so in a calm environment, and when storing it, be careful not to lose it by putting it in a case or a zippered bag.</p><p></p><h2 style="text-align: start" id="hbf11c8f4b5"><strong>Who is recommended to rent WiFi?</strong></h2><p>1.People who have multiple devicesIf you have multiple devices such as a smartphone for work, a smartphone for private use, a tablet device, a camera with WiFi communication, and a PC, renting one WiFi rental is convenient for you to use the Internet on multiple devices at the same time.</p><p>2.People who prefer simple operationThe simple operation is a big attraction, as you only need to enter your password to connect, and there are no complicated settings to be completed.</p><p>3.Short-term users</p><p>The disadvantage of international WiFi rental is the high rental fee, which is a big expense for a long period of time.

Many people choose rental Wi-Fi and SIM cards as their method of using the Internet when traveling abroad. We will review the advantages and disadvantages of each, and also introduce other methods.

Which do you recommend for international travel, Wi-Fi rental or SIM card?

<h2 id="h163248d089">What is tethering?</h2><p>Tethering is the ability for one device to be connected to a cellular network and share its Internet connection with other devices. A smartphone or tablet acts as a mobile Wi-Fi hotspot, providing Internet access to surrounding devices. There are three main ways to connect: Wi-Fi, Bluetooth, and USB.</p><h3 id="h8b40bf460d">Wi-Fi Connection</h3><p>Wi-Fi tethering is the most common and easiest to set up. The device emits a Wi-Fi signal and other devices can connect to its Wi-Fi to access the Internet.</p><h3 id="h8ed5bf2a3a">Bluetooth Connection</h3><p>Tethering over Bluetooth is also possible, but tends to be slower than Wi-Fi. However, it consumes less power than Wi-Fi, making it a good choice if you want to conserve battery power.</p><h3 id="hd382d73f50">USB Connection</h3><p>USB tethering is a direct connection of devices with a USB cable. The connection is more stable and the battery is less of a concern since the device is charged, but a cable is required and only one device can be connected.</p><h3 id="h5b6d2499ea">Reasons for slow communication when tethering</h3><p>The main reasons for slower communication speeds when tethering include signal strength, network congestion, and the processing power of the tethered device. Also, if many devices are connected at the same time, bandwidth may be split, slowing down the speed of individual devices.</p><h2 id="h4f6788b10a">What is eSIM?</h2><p>Embedded SIM (eSIM) is a technology that replaces the traditional physical SIM card and is built into the device. eSIM allows users to remotely activate their cell phone plans and switch between multiple carriers.</p><h3 id="hd16742ba88">eSIM is becoming increasingly popular.</h3><p>According to forecasts by the Ministry of Internal Affairs and Communications, approximately 33.8% of all smartphone shipments are expected to be eSIM-enabled devices by 2024. This figure indicates that eSIM technology is rapidly penetrating the market as a mainstream alternative to conventional physical SIM cards, and its adoption is accelerating among consumers and operators as the convenience of eSIM is recognized (see &quot;Draft Direction of Study | Ministry of Internal Affairs and Communications&quot;).</p><p>The Ministry of Internal Affairs and Communications forecasts that 33.8% of smartphone shipments will be eSIM-compatible handsets by 2024&quot; (Direction of Study (Draft) | Ministry of Internal Affairs and Communications) Reference URL: <a href="https://www.soumu.go.jp/main_content/000735823.pdf">https://www.soumu.go.jp/main_content/000735823.pdf</a></p><h3 id="h8fce2f899b">Can tethering be used with an eSIM?</h3><p>Devices equipped with an eSIM can be tethered in the same way as devices using a conventional SIM card. eSIM itself does not function as a method of providing Internet connectivity, but shares the connection with other devices through the device&apos;s tethering function.</p><h2 id="ha233f9a020">How to set up an eSIM to use the tethering feature</h2><p>Even devices with an eSIM require some configuration to use tethering. Below we explain how to set up tethering on Android and iPhone.</p><h3 id="hc4a740fe66">How to use tethering on Android</h3><ol><li>Open the &quot;Settings&quot; application.<p></p></li><li>Tap &quot;Network and Internet.<p></p></li><li>Select &quot;Hotspot and Tethering.<p></p></li><li>Tap &quot;Wi-Fi Hotspot&quot; and configure the necessary settings. If necessary, also set security settings and passwords.</li></ol><h3 id="hcbd72acb12">How to tether with iPhone</h3><ol><li>Open the Settings app.<p></p></li><li>Tap &quot;Personal Hotspot.<p></p></li><li>Turn on &quot;Allow personal hotspots&quot; and set your Wi-Fi password.<p></p></li><li>Search for a Wi-Fi network on the other device you wish to connect to and connect using the password you set.</li></ol><h2 id="h20ff6512fd">Tethering when traveling abroad is not recommended for some applications.</h2><p>While tethering while traveling abroad can be very convenient, there are some caveats. In particular, if you are considering using a PC or using your smartphone with more than one person, you need to think carefully.</p><h3 id="hca250dcbbe">If you want to use your PC while abroad</h3><p>When using a PC abroad, you need to be aware of its convenience as well as its rapid consumption of communication capacity. Especially when connecting to the Internet through tethering, it is important to pay attention to the following points</p><h4 id="hbb956ab533">Digesting communication capacity quickly</h4><p>PCs are frequently used for data-intensive activities such as high-resolution video viewing, large file downloads, online meetings, and software updates. These activities require special attention when tethering abroad.
