en.Wedoany.com Reported - Users of NTT docomo's "docomo MAX" plan in Japan can enjoy free overseas data communication services in over 200 countries and regions for up to 15 days, without additional charges or prior application. This service has a monthly data capacity limit of 30GB; exceeding this limit will reduce overseas communication speeds to 1Mbps. If the user stays abroad for more than 15 days, the communication speed will be restricted to 128kbps until returning to Japan. Users simply need to enable data roaming settings on their devices, which can be done after departure.
The reporter traveled to Taipei City, Taiwan, from May 31 to June 7 for business, attending the COMPUTEX TAIPEI 2026 exhibition. This marks the reporter's second consecutive year and third time covering the event. This trip was the first time the reporter visited Taiwan after switching the main line plan to docomo MAX and upgrading to the Galaxy S26 Ultra SC-53G 512GB version.
To use overseas data communication, data roaming settings must be enabled on the device. After connecting to the roaming partner's network abroad, an SMS containing precautions will be received, prompting the user to turn on data roaming settings. Once connected successfully, the phone will display the name of the roaming partner's operator. This service supports all operators in the target countries/regions, so manual operator selection is usually unnecessary.
In Taiwan, W-CDMA (3G) communication services have been fully terminated since September 30, 2024, so roaming is conducted via 5G or LTE (4G). During the exhibition, whether using 5G or LTE, communication speeds were sufficient for all needs, with no inconvenience experienced.
Users who have subscribed to "Sekai Sonomama Giga" or docomo MAX lines, and have bound a "Data Add-on" or "5G Data Add-on" line, can also use the overseas data communication service on that add-on line. However, the data communication capacity and contract days are shared with the main line, so users should be careful not to overuse it. During this trip, the reporter brought a PC with a 5G data add-on SIM card as a backup, allowing internet access without using the smartphone's hotspot, which was very convenient, though battery consumption was faster.
Regarding smartphone shutter sound settings, the vast majority of smartphones sold in the Japanese market forcibly emit a shutter sound when taking photos. This is not a legal obligation but a self-regulation by operators and manufacturers. Smartphones sold in the South Korean market, based on a 2004 requirement from the Ministry of Information and Communication (now the Ministry of Science and ICT), must emit a shutter sound of at least 65dB. Smartphones sold outside Japan and South Korea typically allow the camera shutter sound to be turned off. When the Japanese version of the Galaxy S26 Ultra connects to a network outside Japan and South Korea, launching the camera will display a pop-up informing users that they can adjust the shutter sound volume via the system volume. Setting the system volume to zero will completely silence the shutter sound.
The mandatory shutter sound mechanism is intended to prevent covert photography, but most countries have not introduced a similar mechanism. Reports indicate that South Korea is also seeing a trend toward re-evaluating this requirement.
