China eSIM vs Spark, One NZ, 2degrees roaming: 2026 cost check
Last updated 15 April 2026 · 3 min read
A Kiwi traveller saves $55-105 NZD on a week in China — and gets Google Maps and WhatsApp to actually work.
China is the destination where the eSIM vs telco question isn’t just about price. NZ telco roaming in China routes through Chinese domestic networks, which means the Great Firewall applies. Google, WhatsApp, Instagram — all blocked.
A foreign-routed eSIM bypasses the firewall. Your phone works normally.
The bottom line
For 7 days in China at normal usage (5-8 GB):
| Option | Total cost (NZD) | Google/WhatsApp work? |
| Travelren China eSIM (foreign-routed) | $30 | Yes |
| Travelren China eSIM (10 GB / 30 days) | $50 | Yes |
| Spark Travel Pack (China) | $56 | No (firewalled) |
| One NZ Daily Roaming | $70 | No (firewalled) |
| 2degrees Roaming Pass | $63 | No (firewalled) |
The eSIM is $26-40 NZD cheaper and bypasses the firewall. The second part matters more.
How each NZ telco handles China
Spark Travel Pack — $8 NZD/day for China. Seven days = $56. Routes through China Mobile or China Unicom — firewall applies.
One NZ Daily Roaming — $10 NZD/day. Seven days = $70. Firewalled.
2degrees Roaming Pass — $9 NZD/day. Seven days = $63. Firewalled.
All three NZ telcos offer working data roaming in China. None of them bypass the Great Firewall. Google, WhatsApp, Instagram, Gmail — all blocked unless you run a VPN.
Why the firewall matters
Paying $70 to One NZ for a week of “roaming in China” gives you a phone where Google Maps doesn’t load and WhatsApp can’t connect. You’d then need a VPN on top, which is unreliable in China (the firewall targets VPN traffic) and legally grey.
A foreign-routed eSIM routes your data through Hong Kong or overseas before the firewall filters it. Google Maps, WhatsApp, Gmail — all work immediately, no VPN.
The bill-shock risk
NZ telcos auto-trigger roaming charges on first data use in China. If the pack fails to activate, per-MB rates can hit dollars per megabyte. Background app activity for a day has produced four-figure bills.
An eSIM is prepaid.
When the NZ telco option is worth it
Two scenarios:
1. Business trips with a corporate VPN. The VPN tunnels Google and WhatsApp over the work network. Company pays the roaming bill, you keep your NZ number live.
2. WeChat-only trips. If you’re in China for a trade show and WeChat handles everything, domestic Chinese data works. Most holidaymakers can’t survive without Google and WhatsApp.
For everyone else, the foreign-routed eSIM is the answer.
Two-week and longer trips
Over 14 days in China:
- Spark — $112 (firewalled)
- One NZ — $140 (firewalled)
- 2degrees — $126 (firewalled)
- Travelren China eSIM (10 GB / 30 days, foreign-routed) — $50
Savings are $62-90 on a two-week trip. Plus Google actually works.
What Kiwis specifically should know
China isn’t in any NZ telco’s free-roaming zone. You’re paying daily roaming on every option. The question is whether the phone you’re paying for actually loads Google.
Check if your phone is eSIM-compatible. iPhone XS (2018) and newer, Samsung Galaxy S20 and newer, Pixel 3 and newer. Check yours at our device check tool.
Keep your NZ SIM for bank 2FA. ASB, ANZ, Westpac, BNZ, and Kiwibank SMS codes need your NZ number live. Dual SIM (eSIM for data, NZ SIM with roaming off) keeps this working free.
Skinny and Warehouse Mobile don’t roam in China. eSIM is mandatory for MVNO customers — and savings are largest because there’s no alternative.
Alipay and WeChat Pay accept international cards. Both support Visa and Mastercard for most transactions (2024+). You don’t need a Chinese bank account for 95% of tourist spending.
Auckland-Shanghai direct flights are coming back. Air New Zealand resumed direct service in 2024-25 after the pandemic hiatus. If you’re flying direct, your eSIM activates cleanly on the first Shanghai tower. If you transit through Sydney or Hong Kong, the eSIM doesn’t activate until you actually land in China.
Install before you fly — critical. Many eSIM providers’ own websites are blocked in China. If your eSIM fails to activate and you try to reach support from Shanghai hotel Wi-Fi, you may not be able to. Install and save support contacts offline at home.
What to do next
1. Check your phone works with eSIM (60 seconds) 2. Browse China plans — look for “foreign-routed” or “Hong Kong routing” 3. Install the eSIM on home Wi-Fi before you fly. Save support contacts offline. 4. Land, switch data to your China line, test with Google Maps

Frequently asked questions
Does Spark's Travel Pack cover China?
Yes, at $8 NZD/day. But it routes through Chinese domestic carriers, so Google, WhatsApp, and Instagram are blocked by the firewall. You'd need a VPN on top.
Will Google Maps work with a China eSIM?
Yes, with a foreign-routed China eSIM. Domestic China SIMs do not bypass the firewall.
Is a foreign-routed eSIM legal in China?
Yes. International roaming has always worked through foreign carrier agreements — you're using the standard inbound tourist data path.
Will my NZ bank SMS codes still work?
Yes, if you keep your NZ SIM active on a second line with data roaming off. SMS and calls reach your NZ number free.
What about Skinny or Warehouse Mobile?
Neither offers usable China roaming. An eSIM is mandatory.
