海外旅行eSIM
运营商漫游往往是海外上网最贵的方式。旅行eSIM可让您为目的地购买预付费流量，出发前安装，落地即连。
What is a travel eSIM?
An eSIM is a digital SIM built into your phone. Instead of swapping a plastic card, you scan a QR code and activate a prepaid data plan for a specific country or region.
Your primary number stays active for calls and SMS (if your plan allows). The travel eSIM handles mobile data.
When a travel eSIM makes sense
- Short trips (1–4 weeks) where a local SIM is inconvenient
- You need data immediately at the airport
- Your home roaming is over $5–10/day
- You travel to multiple countries and want one checkout
PayCall: eSIM + calling in one place

常见问题
- Can I use a travel eSIM and still receive calls on my home number?
- Usually yes — the eSIM is data-only. Keep your primary SIM for voice/SMS and enable data on the eSIM line.
- Do I need eSIM to use PayCall calling?
- No. PayCall calling works on WiFi. eSIM is optional for when you need mobile data away from WiFi.
