Question: What is the “China Telecom UK branch eSIM, 50GB/year, switchable between domestic (China) and international (UK) traffic”?

Answer:

This is CTExcel — China Telecom International’s brand operating in the UK, France, Hong Kong, Canada, Italy and other regions, offering mobile data, voice, SMS, one-card-multi-number, eSIM, and other value-added services. It was launched in the UK in 2012 by China Telecom (Europe) Ltd, designed specifically for Chinese students, tourists, and business visitors.

The key feature: shared China+UK data pool

The data allowance is shared between China and the UK — meaning UK plan data can be used in mainland China. This is the “内外网流量随时切换” feature you’re describing: one pool of data that works both in the UK (on EE network) and in mainland China (on China Telecom’s domestic network), and you can use it in either country at any time.

CTExcel cooperates with EE, one of the UK’s mainstream mobile network operators, providing 4G network coverage plus free roaming in 48 countries and regions.

Critical activation requirement

Activation cannot be done in mainland China — you must activate it in the UK/Europe before it can be used in mainland China.

eSIM specifics

eSIM replacement is supported; the first switch from physical SIM to eSIM is free via the backend, and further eSIM-to-eSIM swaps cost £3 each.

Why this is interesting for your use case

If you’re in Guangzhou and want clean access to Google, GitHub, Hugging Face, etc. without a VPN setup — this SIM routes your data through the UK carrier’s international link, effectively bypassing GFW because the data plane is treated as international roaming, not domestic Chinese traffic. The 50GB/year annual plan at low cost is a popular choice for this reason among Chinese tech workers who’ve spent time in the UK.
