As a savvy international traveler, digital nomad, or curious explorer, staying connected across borders is essential. The good news? You don’t need to rely on overpriced roaming or hunt for local SIM cards. With the right eSIM plan, you can enjoy seamless connectivity across Hong Kong, Macau, and even China—if you know what to look for.

Adding Hong Kong or Macau to your route?
Here’s our must-visit guide—perfect for culture lovers & curious explorers.
I. How eSIM Coverage Works Across Hong Kong and Macau
If you’re planning to visit both Hong Kong and Macau, it’s tempting to think you can just grab a single eSIM and be good to go. But here’s the thing: coverage isn’t guaranteed across the border—even if the regions are only an hour apart by ferry.
Here’s why:
- Hong Kong and Macau operate under different telecom networks and regulations.
- Even though some eSIM providers offer plans that say they work in both, not all do in practice—or only offer reduced speeds in Macau.
- Some Hong Kong eSIMs (like Airalo’s popular CSL plan) don’t support Macau at all.
👉 TL;DR: A Hong Kong eSIM may work in Macau if your provider explicitly lists Macau in the coverage area. Otherwise, expect no service—or limited access.
Real-World Example
Let’s take Airalo’s Hong Kong eSIM as an example. It runs on the CSL network, which has no roaming agreement in Macau. Result? You’ll lose data once you cross the border.
By contrast, eSIMs from Holafly or GOHUB (Asia Multi-Country Plan) clearly list Macau + Hong Kong as supported regions and switch between local partner networks automatically.
What to Look For in a Cross-Border eSIM:
| Feature | Why It Matters |
|---|---|
| Coverage List | Ensure both “Hong Kong” and “Macau” are named explicitly. Avoid vague “Asia” mentions. |
| Network Partners | Plans using CTM (Macau) and CSL or 3HK (HK) usually offer stronger cross-border stability. |
| Speed Limits & FUP | “Unlimited” often means throttled after a daily high-speed cap. |
| Hotspot Capability | Not all plans let you share data in Macau—check hotspot terms. |
| ID Verification | Real-name registration is mandatory in HK for all eSIMs. Some providers make it easy; others don’t. |

III. Does Hong Kong eSIM Work in Macau? How to Check Before You Go
Before you hop the ferry or cross the bridge to Macau, double-check that your eSIM has you covered—literally. Here’s a foolproof checklist to avoid connection blackouts on arrival:
1. Read the Plan Description Carefully
Look for “Macau” listed explicitly in the coverage section.
If it only says “Hong Kong” or “Asia,” that’s not a guarantee—Macau is often excluded.
- ✔ Good: “Coverage: Hong Kong + Macau”
- ✘ Risky: “Coverage: Asia / Hong Kong”
2. Check the Supported Networks
Make sure the eSIM connects to CTM Macau, the main carrier in the region.
Example:
- ✅ eSIM with 3HK + CTM → Solid dual-region coverage
- ❌ eSIM with only CSL → Works in HK only
3. Look for User Reviews or Provider Notes
Reputable eSIM providers often mention:
- “Not available in Macau”
- “Best for Hong Kong travel only”
- “FUP: 1GB/day then slowed to 512kbps”
Red flags = unclear terms or no mention of Macau.
4. Ask Customer Support (If You’re Unsure)
Reach out to the provider via live chat or email. Ask directly:
“Does this eSIM work in both Hong Kong and Macau with full-speed data?”
If they hesitate or don’t answer clearly, consider switching.
5. Verify Your Phone is eSIM-Compatible and Unlocked
Even the best plan won’t work if your device isn’t compatible.
Quick test:
- ✅ iPhones XR and newer
- ✅ Most Pixel & Samsung S20+
- ❌ iPhones bought in Mainland China (except a few models)
IV. Do I Need a Separate eSIM for Macau?
Short answer? It depends on your current plan.
Long answer? Let’s break it down.
When You Don’t Need a Separate Macau eSIM:
If your existing eSIM plan explicitly lists Macau as a supported region (alongside Hong Kong), and connects to a Macau-based network like CTM, you’re good to go. Just turn on roaming when you arrive, and you’ll stay connected seamlessly.
Examples of plans that work across both regions:
- GOHUB Asia eSIM
- Holafly Hong Kong + Macau + China eSIM
- eTravelSim multi-region Asia eSIM
- iRoamly Asia Pass
These are perfect for travelers doing short stays in Macau or hopping between regions.

When You Do Need a Separate Macau eSIM:
You’ll need to buy a dedicated Macau eSIM if:
- Your current plan is Hong Kong-only (like Airalo’s CSL plan).
- The provider doesn’t mention Macau in its supported countries.
- You plan to use data-heavy apps (e.g. video calls, navigation) and want maximum speed via local network access.
Why This Matters:
Macau’s network infrastructure is independent of Hong Kong’s, and many eSIMs that work well in HK don’t automatically roam into Macau—or they do so with slower speeds, higher latency, or no connection at all.
If you plan to:
- Stream HD content
- Navigate on foot in older districts
- Use hotspot for multiple devices
…a Macau-specific eSIM could save you frustration.
GOHUB Tip:
Even if you’re just doing a day trip to Macau, it’s worth verifying your eSIM coverage or spending a few dollars on a short-term Macau add-on. Better safe than SIM-less.

VI. Frequently Asked Questions: Hong Kong & Macau eSIM Edition
Q1: Does a Hong Kong eSIM work in Macau?
Sometimes. Only if your eSIM plan explicitly includes Macau in its coverage. Popular Hong Kong-only plans (like Airalo’s CSL eSIM) do not work in Macau. Look for providers like GOHUB, Holafly, or eTravelSim that clearly state support for both regions.
Q2: Do I need a separate eSIM for Macau?
Only if your current eSIM doesn’t support Macau. If your plan is Hong Kong-only, and you want fast, reliable internet in Macau, getting a separate Macau eSIM or multi-region Asia eSIM is the smart move.
Q3: Can I use hotspot/tethering with a Hong Kong eSIM in Macau?
That depends on the provider. Many do allow tethering (including GOHUB and eTravelSim), but some limit hotspot use, especially on “unlimited” plans. Holafly, for example, restricts daily hotspot data in Macau to 500MB.
Q4: Will I get full-speed 4G/5G data in both regions?
Yes, if your eSIM connects to strong local networks like CTM Macau and CSL or 3HK in Hong Kong. Avoid global “Asia” eSIMs that don’t clarify specific carrier partners—they may roam on slower speeds or throttle early.
Q5: Do I need to verify my identity to use an eSIM in Hong Kong or Macau?
Yes for Hong Kong. All eSIMs in Hong Kong SAR require real-name registration, usually done online after installation. You do not need a Hong Kong ID—your passport works. Macau does not require identity verification for eSIMs as of now.
Q6: What devices support eSIM in this region?
Most newer phones from 2020 onward do.
✅ iPhone XR and newer (except mainland China models)
✅ Google Pixel 3 and up
✅ Samsung Galaxy S20, Z Fold, Z Flip, Note 20
❌ Many iPhones bought in Mainland China, Hong Kong, or Macau don’t support eSIM (except specific models like SE, XR, XS, 13 Mini).
VII. Final Thoughts: Stay Seamlessly Connected Across Hong Kong & Macau
Traveling between Hong Kong and Macau doesn’t have to mean juggling SIM cards, losing coverage, or overpaying for roaming. By choosing the right multi-region eSIM, you can stay connected with fast 4G/5G speeds, use hotspot on the go, and explore confidently—whether you’re riding the Star Ferry in Hong Kong or wandering the Senado Square in Macau.
