Two kinds of Hong Kong eSIM
All of these are 5G roaming plans. The difference is where they work and which Hong Kong networks they use.
| Plan | Networks in Hong Kong | Hong Kong | Macau | Mainland China |
|---|---|---|---|---|
| Best Hong Kong, Best Hong Kong Unlimited | 3HK, China Mobile HK | ✓ | — | — |
| China Hong Kong Macau (all types) | CSL, SmarTone | ✓ | ✓ (CTM) | ✓ |
A day trip to Macau by ferry or across the border to Shenzhen is common. If that's in your plan, buy China Hong Kong Macau: one eSIM, no swapping at the border. In mainland China it still opens Google and WhatsApp because it's a roaming plan; see China eSIM without a VPN.
Prices by the GB
| Data | Plan | 3 days | 5 days | 7 days |
|---|---|---|---|---|
| 3GB | Best Hong Kong | ฿79≈ $2.61 | ฿89≈ $2.94 | ฿99≈ $3.27 |

Unlimited
| Plan | 3 days | 4 days | 5 days |
|---|---|---|---|
| Best Hong Kong Unlimited 10 Mbps | ฿239≈ $7.89 | ฿309≈ $10.20 | ฿379≈ $12.51 |
| Best Hong Kong Unlimited full speed | ฿299≈ $9.87 | ฿389≈ $12.84 | ฿479≈ $15.81 |
| China Hong Kong Macau Unlimited 10 Mbps | ฿269≈ $8.88 | ฿349≈ $11.52 | ฿429≈ $14.16 |
| China Hong Kong Macau Unlimited full speed | ฿349≈ $11.52 | ฿459≈ $15.15 | ฿559≈ $18.45 |
10 Mbps is enough for maps, social media and video calls. China Hong Kong Macau's full-speed option gives 5GB a day at full speed, then 10 Mbps. Until 31 Dec 2026 Vacay runs Best Hong Kong Unlimited full speed at full speed for the whole plan at the same price. After that it works like the others: 5GB a day at full speed, then 10 Mbps.
Daily plans
China Hong Kong Macau Daily works in all three places and gives full-speed data up to a daily limit, then drops to 128 kbps, which is only enough for text messages. You can't top it up.
| Per day | 2 days | 3 days | 4 days | 5 days |
|---|---|---|---|---|
| 500MB | ฿29≈ $0.96 | ฿39≈ $1.29 | ฿49≈ $1.62 | ฿59≈ $1.95 |
| 1GB | ฿39≈ $1.29 | ฿59≈ $1.95 | ฿79≈ $2.61 | ฿99≈ $3.27 |
| 2GB | ฿69≈ $2.28 | ฿109≈ $3.60 | ฿139≈ $4.59 | ฿179≈ $5.91 |
For 2 to 3 days, daily is the cheapest: 1GB a day for 3 days is ฿59 (≈ $1.95), less than Best Hong Kong 3GB for 3 days (฿79 (≈ $2.61)), and it works in Macau and China too.
