PCWorld lists Japan eSIM checks for iPhone, Pixel, and carrier locks

TL;DR: PCWorld said travelers to Japan should check eSIM support, carrier-unlock status, data allowance, activation timing, and local network coverage before buying a travel eSIM. The article cites iPhone XS/XR and newer, Pixel 4 and newer, and provider differences including NTT Docomo, KDDI, and SoftBank network access.

PCWorld said travelers should confirm both eSIM compatibility and carrier-unlock status before buying a Japan eSIM. The article says Apple supports eSIM on iPhone XS, XS Max, XR, and newer models, Google supports eSIM on Pixel 4 models and newer, and Samsung support varies by model and region. On iPhone, users can check lock status in Settings > General > About > Carrier Lock.

PCWorld said Japan eSIM buyers should match plan size to expected usage and review fair-use terms on unlimited offers. The article says light use such as maps, train schedules, messaging, and web searches may fit 10GB to 15GB, while heavier use such as social media, photo uploads, and music streaming may require 30GB to 50GB or an unlimited plan. It names Ubigi, Airalo, Saily, Nomad, and Holafly as providers offering different plan structures, including fixed-data plans, 50GB options, and unlimited plans for up to 30 days.

PCWorld said coverage in Japan can vary because travel eSIM brands use different local mobile networks. The article says Ubigi uses NTT Docomo in Japan and supports 5G where available, Jetpac uses KDDI, and Holafly connects through KDDI and SoftBank. It says this matters more for travel outside Tokyo, Osaka, and Kyoto, including rural areas, mountains, and smaller islands.

PCWorld said many Japan travel eSIMs are data-only and that activation timing differs by plan. The article says Ubigi and Saily focus on data-only service, while Mobal offers voice-and-data eSIMs with Japanese 070, 080, or 090 numbers and Sakura Mobile offers separate voice-and-data plans while its short-term travel eSIMs are data-only. It also says Sakura Mobile's Unlimited Data eSIM starts when it first connects in Japan, while its 3GB-per-day Travel eSIM starts immediately on installation.
