Travel eSIM
eSIM for China
China is the trip where connectivity planning matters most, because many of the apps and services travelers rely on elsewhere behave differently there. Arriving with a working data plan already loaded means you're not troubleshooting connectivity in an airport queue. Check your own app requirements before you fly, and confirm with the partner what their China plan does and doesn't include.

How eSIM works in China
eSIM support for visitors in mainland China is more limited than in most destinations, and travel plans generally route through China Mobile, China Unicom, or China Telecom. Read the partner's plan details for China carefully before purchase.
Buy the plan, scan the QR code the partner emails you, and install the profile while you're still on Wi-Fi. Switch the line on when you land.
How much data do you need?
Data needs depend heavily on which apps you use and how you route your traffic, so plan conservatively and choose a bundle you can top up.
Going abroad from the US?
Every S Mobile unlimited phone plan already includes world eSIM data and free calling and texting to 85+ countries — so your everyday plan travels with you before you even add a destination eSIM.
FAQs — travel eSIM in China
Will my phone work with an eSIM in China?
Most recent iPhone, Google Pixel, and Samsung Galaxy models support eSIM, but your phone also has to be carrier-unlocked. Check your phone's settings for an "Add eSIM" or "Add cellular plan" option before you buy, and confirm device compatibility with the partner at checkout.
How do I set up a travel eSIM before flying in China?
Buy from the partner store, then install the eSIM profile while you still have Wi-Fi at home. It stays dormant until you arrive and switch it on, so you land connected without hunting for a SIM counter.

Can I keep my US number while using a travel eSIM in China?
Yes. A travel eSIM adds a data line alongside your existing line, so your US number stays active for calls and texts over Wi-Fi or your regular plan while data runs on the travel eSIM.
Does S Mobile Wireless run the network in China?
No. Travel eSIM data abroad runs on partner networks, not on our US network. Plans are sold and supported by our partner and billed separately from any S Mobile account.
