Prepaid travel data for Asia, and Hong Kong numbers that keep working abroad

UncleSim is a Hong Kong connectivity provider. We supply prepaid eSIM data plans for international travellers, and Hong Kong mobile numbers for customers who live outside Hong Kong but need to retain one.

Our customers generally fall into two groups: travellers arriving in Asia who need data working from the moment they land, and Hong Kong residents abroad who require a Hong Kong number for banking verification, family contact, and continuity of service.

Who we serve

Hong Kong customers living abroad. Retaining a Hong Kong number is the priority. We offer long-validity Hong Kong plans, and we can transfer a number customers already own onto an eSIM.

Travellers from the North America and Europe visiting Asia. A single plan covering the whole itinerary, installed before departure and active on arrival, without depending on airport SIM counters or hotel networks.

Multi-region itineraries. Multi-region plans cover more than 100 regions on one eSIM, so a route through several destinations requires one purchase rather than several.

What we offer

  • Prepaid travel eSIM data plans - regional and multi-region, each with a stated data allowance, speed, and validity period.
  • Hong Kong local plans - from short visits to multi-year plans that retain both the number and a data allowance.
  • Number port-in - transfer an existing Hong Kong number to an eSIM.
  • China plans with a Singapore breakout IP - so the applications our customers depend on at home continue to function as expected.

How it works

  1. Select the plan that matches your destination.
  2. Pay in your own currency. The eSIM is delivered by email as a QR code, normally within minutes.
  3. Install the eSIM before departure and activate it on arrival. The validity period begins at the first connection in the destination, not on the date of purchase.

Our commitments

Clear pricing. The data allowance, speed, and validity period are stated on every plan, and the price shown is the price charged. There are no activation fees, no surcharges, and no contractual commitment.

Appropriate recommendations. Where a lower-priced plan is not suited to the way a customer intends to use data, we recommend the plan that is. A plan that underperforms reflects poorly on us as much as it inconveniences the customer.

Digital delivery, worldwide. Every product is delivered by email. There is no shipping, no physical item to misplace, and the service operates identically whether the order is placed in Hong Kong, London, or Los Angeles.

About UncleSim

UncleSim operates from Hong Kong and serves customers in English and Traditional Chinese. We are a small team selling directly, which means enquiries are handled by the people who process the orders.
