Our verdict on each
China Unicom
A Chinese-language indexed China Unicom page lists China United Network Communications Group Company Limited and China United Network Communications Company Limited.
Ucom
Ucom is a carrier-run eSIM built for short trips, with the same bundle price in the US, Europe, the UK and Japan and 5G on the plan. It suits travelers who want a small capped allowance and a single price across a region, not those chasing a wider country list or unlimited data.

Pros and cons
Ucom
Pros
- 5G is available and the eSIM is sold as a carrier plan, both listed under 5g and carrier plan.
- Top-ups are available, so data can be added mid-trip without buying a new plan.
- Roaming lands on partner networks including Vodafone, Orange, T-Mobile, Swisscom and Chunghwa Telecom, listed under Vodafone, Magenta and A1.
Cons
- Unlimited data: no, so heavy streaming or navigation abroad runs into the fair use policy.
- Coverage is 53 countries, well short of Zwitchy at 200.
- Unused data lapses when the validity period ends, and usage past the allowance continues at the visited operator's roaming rates.

Questions about each
Ucom
How much does a Ucom travel eSIM cost?+
Bundles start at AMD 1,990 and step up through a few data sizes, so the price tracks how much data you expect to use rather than the destination. A US bundle is AMD 9,500 and a Japan bundle is AMD 9,500, which keeps planning simple across regions.
Is the data unlimited?+
Unlimited data: no. Ucom sells capped bundles, and its fair use policy nullifies unused data when the validity period ends. Once the allowance is used up the session continues at the visited operator's roaming rates, so extra usage is billed at roaming prices rather than at plan rates.
Which countries does the Ucom eSIM cover?+
The plan covers 53 countries, a mid-sized list for a regional trip. For comparison, Zwitchy lists 200 countries, so a multi-continent itinerary may stretch past what Ucom covers, while a short trip across the US or Europe sits inside the list.
Which networks does it roam on?+
Roaming runs on partner networks including Vodafone, Orange, T-Mobile, Swisscom, Chunghwa Telecom and Ooredoo, and the full set sits under Vodafone, Magenta and A1. Because the service comes from a carrier based in Armenia, the connection lands on the host network in each country, so speed follows that operator.
