Setup
SmarTone says a customer moving a number should keep the existing service active through the transfer and should not ask the old operator to terminate it. The eSIM is downloaded and activated by scanning the QR code, without inserting a physical SIM.
Hong Kong 5G Reach
Coverage is built around 5G across Hong Kong. A road test covering 18 districts found 5G signal in every area it reached, including main roads, trunk roads, road tunnels and overpasses. Customers who travel between districts therefore have a consistent connection on the move. The test used a defined signal threshold to judge each area, so the result is measured against a set standard rather than a general impression.
A Hong Kong mobile operator
The brand is a mobile operator serving Hong Kong, with a fifth generation network designed for everyday use across the city. Customers can run service on a phone in more than one way, either with a traditional card or with a digital card built into the handset. Multiple lines are part of the offer, so a supplementary card can be added for family members. The network is aimed at heavy data use, and the operator keeps its focus on mobile connectivity for local customers.
Built around the digital SIM
A digital SIM is built into the phone rather than sitting in a tray, so no card needs to be inserted and none can be lost or damaged. Activation is handled by scanning a code supplied by the operator. The digital SIM stays tied to the device it was installed on, so it cannot be moved to another phone, which helps protect the account if a handset goes missing. A digital SIM and a physical SIM carry different numbers and can run side by side on one phone, which suits people who keep two lines.
