Mainland iPhone 16 Pro has no eSIM — what to do
Since late 2024, most mainland-China iPhone users hit the same bad news the moment they need eSIM: the mainland iPhone 16 / 17 series has no eSIM at the hardware level. This isn't a software lock — restoring, region change, jailbreaking, none of it helps. The eUICC chip is simply not populated on these mainland boards.
So what do you do for international travel? We put four mainstream options side by side.
Option 1: physical-SIM-to-eSIM chips (Estk / 5ber / esim.me)
The most popular workaround among mainland iPhone Pro owners.
How it works: you buy a "programmable physical SIM" that has the same shape as a regular nano-SIM, write the destination eSIM profile onto it, and pop it into the iPhone's physical tray — iOS treats it as a normal physical SIM, not knowing it's secretly an eSIM.
Common chips:
- Estk — available domestically, written from an app, ~¥150, multiple profiles rewriteable.
- 5ber — popular overseas, NFC-written, stores 5+ profiles.
- esim.me — European brand, slightly pricier, best compatibility.
Pros:
- Works on every mainland iPhone, including 16/17 Pro with no eSIM hardware.
- One-time investment, reusable.
- Sold and shipped within China — no overseas purchase needed.
Cons:
- Learning curve (PC app or an Android NFC phone to write).
- Some providers (e.g. Holafly) lock the profile and refuse third-party chips.
- Still occupies the physical tray — if your main number is a physical SIM, you'll have to take it out.
Best for: frequent travellers, willing to set things up once, optimising for cost.
Option 2: pocket Wi-Fi / portable hotspot
Rent or buy a 4G/5G pocket router, insert a local data SIM on arrival, and share among the group.
Pros:
- Zero configuration, plug-and-play.
- Multiple devices (phone, iPad, laptop).
- Cost amortised across a family/team.
Cons:
- One more device to carry and recharge daily.
- Easy to lose or get stolen.
- Data plans usually 30-50% pricier per GB.
- The moment the router is separated from you, your phone is offline.
Best for: family / team trips, 3+ travellers, lots of devices.
Option 3: just buy a Hong Kong or international iPhone
If you're due for an upgrade and travel often, this is the permanent fix.
- Hong Kong: physical SIM + eSIM dual line; you can keep your mainland number AND a roaming eSIM, no swapping.
- International (JP / UK / EU): physical + eSIM.
- US: eSIM only, no physical tray — slimmest, but in mainland China you'd need to convert your original physical number to eSIM (Unicom supports this).
Price gap: a Hong Kong iPhone 17 Pro is ~¥500-1000 more than mainland, but the premium holds up in the used market.
Best for: due to upgrade + travelling 2+ times a year.
Option 4: borrow a friend's international phone
For a quick 1-3 day trip, borrow a spare international phone (a friend's old international iPhone, Pixel, or Galaxy works), buy a 7-day Airalo plan, and you're done for a few bucks.
Pros:
- No long-term cost.
- Your main phone stays untouched.
- The lent phone is sitting idle anyway.
Cons:
- Logging into Apple ID and reinstalling apps on the loaner.
- iMessage / WeChat will trigger security verification on a new device.
Best for: 3-day trips with no appetite for any long-term setup cost.
5. Four-option cheat sheet
| Option | Upfront | Recurring | Learning curve | Best for |
|---|---|---|---|---|
| Physical-to-eSIM chip | ¥150 | Just data | Medium | Frequent travel |
| Pocket Wi-Fi | ¥0-300 | ¥30-60 / day | Low | Group travel |
| HK iPhone | +¥500-1000 | Low | Low | Upgrade this year |
| Borrow + Airalo | ¥0 | Per-trip data only | Low | 1-3 day trip |
6. Don't bother with these
- Domestic carrier international roaming: ¥30-100+ per day, throttled to 3G, never been "value" in 10 years.
- Airport tourist SIMs: counters in Japan / Europe airports are typically 2-3× the Airalo price.
- Taobao "eSIM unlock services": sellers claiming they can "unlock eSIM" on mainland iPhones — this is a scam. If the hardware chip isn't there, no service can add it.
7. Bottom line
- Frequent traveller → just buy a Hong Kong iPhone.
- Occasional traveller + not upgrading → physical-to-eSIM chip.
- 3-day trip → borrow a phone.
- Family travel → pocket Wi-Fi as the safety net.
