3 Hong Kong SIM Cards Compared: SoSIM, Lucky SIM, and Birdie

Why Choose a No-Contract SIM Card?

In recent years, no-contract SIM cards have gained popularity in Hong Kong due to their high flexibility, affordability, and freedom from long-term commitments—perfect for various lifestyles and user needs. However, with many brands available, how do you choose the right one? This article compares three popular options—SoSIM, Lucky SIM, and Birdie—by analyzing price, speed, network stability, and special features to help you make the best choice.

SoSIM (by 3HK): The Balance of Stability and Value

Price & Plan Features

• First-month cost is only around HK$33, with up to 50GB local data and 1,500 call minutes.

• Offers multiple packages such as unlimited streaming, student e-learning bundles, and roaming plans.

Speed & Stability

• Tested average download speed: 20–40 Mbps. Stable performance across Hong Kong, suitable for daily streaming and work.

• Advantage: Even in busy locations like MTR stations, connections remain consistent with minimal dropouts.

Functions & User Experience

• App available for easy top-up and usage tracking.

• eSIM supported. Number porting is fast and admin fee-free.

Lucky SIM: Entry-Level Prepaid Option for Light or Short-Term Use

Price & Plan Features

Lucky SIM is not a monthly subscription but a one-time prepaid SIM with fixed validity and data (e.g., “30 days/40GB” or “60 days/80GB”). No auto-renewal. Once expired, it deactivates. However, users can top up to extend validity or buy additional data. This makes it ideal for short-term visitors, returning residents, or seniors and students with low data needs.

Speed & Stability

Lucky SIM is a local MVNO (Mobile Virtual Network Operator) that leases csl. network infrastructure. Coverage is generally good, but in busy areas like Mong Kok or MTR stations, speed may drop to 1–5 Mbps, with occasional disconnections. Fine for basic use like messaging and browsing, but not recommended for heavy streaming or downloads.

Functions & User Experience

As the most affordable option, Lucky SIM doesn’t support eSIM or VoWiFi. However, it works well for emergency backup data or temporary usage, making it an appealing budget choice.

Birdie (by SmarTone): A Flexible Option for Power Users

Price & Plan Features

• First month is free, followed by higher rates (e.g., HK$98 for 16GB data).

• Multiple plans available, suitable for medium to heavy data users.

Speed & Stability

• Stable average download speed of 30–40 Mbps; best performance noted inside MTR stations.

• After FUP (Fair Usage Policy), speed is reduced to 2 Mbps—much better than the 128 kbps cap of SoSIM and Lucky SIM, enough for basic video streaming.

Functions & User Experience

• Night data (1 AM to 6 AM) is unlimited and doesn’t count toward the main quota—great for night owls.

• Supports VoLTE and VoWiFi for more stable calls in low-signal areas.

• Flexible roaming plans, including 12-country Asia travel bundles.
