🥈 Option Two: Multi-Telecom Roaming Plan — More Comprehensive Signal Coverage

In addition to SoftBank's native network, yosim also offers eSIM plans with multi-telecom roaming , which are especially suitable for travelers with wide travel ranges who frequently visit remote areas or mountainous regions.

✨ What are the advantages of multi-telecom roaming?

eSIM with multiple roaming plans is not limited to a single telecom operator; it allows users to freely switch signals between multiple local telecom operators (such as SoftBank, Docomo, etc.).

• Improved coverage: When you enter an area where a single telecom operator's signal is weak, your phone will automatically roam and connect to another telecom network with a stronger signal. This significantly reduces the chances of encountering dead zones.

• Optimize connection stability: In popular tourist attractions with large crowds and network congestion (such as Universal Studios and Disneyland), multi-telecom roaming can help you connect to lines with lighter loads, ensuring connection stability and speed.
