Holafly vs AeroSims for China (2026): Which Unlimited eSIM Beats the Firewall?
Holafly vs AeroSims for China (2026): Which Unlimited eSIM Beats the Firewall?
Updated July 2026 · Prices verified at provider checkouts and subject to change
For mainland China the two unlimited eSIMs cost almost exactly the same — so the decision comes down to what happens after you land: firewall access, speed caps, hotspot and setup. Here’s the honest head-to-head, with Airalo as a third reference.
The quick verdict
Pick AeroSims if you want genuinely uncapped data, full hotspot use and a QR code by email with no app — at essentially the same price as Holafly ($28.43 vs ~$27 for a week).
Pick Holafly if its long review history matters more to you than the undisclosed fair-use threshold and the ~500 MB/day hotspot limit.
Light user? AeroSims’ fixed China data packages cover mainland + Hong Kong + Macao in ONE plan: 5 GB for $11.90 or 10 GB for $19.90 (valid 30 days) — QR by email, nothing to download behind the firewall. Airalo’s fixed plans are the app-based alternative.
| 7-day China | AeroSims | Holafly |
|---|---|---|
| Price (7 days) | $28.43 | ~$27 |
| Price per day | $4.06 | ~$3.90 |
| Data | Unlimited | Unlimited |
| Stated throttling | None advertised | Undisclosed cap |
| Google/WhatsApp access | Works — no VPN needed | Works — no VPN needed |
| App required | No — QR email | No (optional) |
| Hotspot | Included | ~500 MB/day |
| Money-back | 30-day guarantee | Limited |
Green marks the better option per row — on price the two are a wash for China; AeroSims wins on terms. Prices reflect publicly listed rates as of July 2026 — confirm at checkout.
The firewall question, answered first
It’s the thing everyone worries about, so let’s settle it: both AeroSims and Holafly route your traffic through gateways outside the mainland. Google Maps, Gmail, WhatsApp, Instagram and your usual apps work out of the box — no separate VPN subscription, no configuration. Holafly markets this as a “built-in VPN”; AeroSims does the same thing without the label. Local SIMs and hotel Wi-Fi, by contrast, sit behind the Great Firewall, which is exactly why a travel eSIM is the sane choice for China.
One practical tip either way: set everything up before you land. App-store downloads and account logins can be slow or blocked once you’re inside China — an emailed QR code you scan at home sidesteps the problem entirely.
- No advertised speed cap. Holafly’s fair-use threshold for China isn’t published; Airalo’s unlimited openly steps down after a daily allowance. AeroSims states no cap at all — the clearest differentiator at equal prices.
- Full hotspot. Tether your laptop or a travel companion freely; Holafly caps sharing at roughly 500 MB a day.
- No app, ever. QR by email in seconds — nothing to download behind the firewall.
- 30-day money-back guarantee. A real backstop if something doesn’t work on your device.
- Brand familiarity. Holafly and Airalo have years of China-traveler reviews; AeroSims is the newer name.
- A dollar a week. At list prices AeroSims is about $1.40 more for 7 days. If that decides it, take Holafly — we’d rather say so plainly.
Coverage and speed on the ground
Both ride China’s major carriers with 4G/5G in Beijing, Shanghai, Xi’an, Chengdu, Shenzhen and along the high-speed rail corridors. Expect strong signal in cities and tourist sites (yes, including most of the Great Wall sections tourists visit) and thinner coverage in remote western regions. The practical difference for most travelers isn’t raw coverage — it’s throttling policy, which loops back to AeroSims’ no-stated-cap promise.
Frequently asked questions
Do Google, WhatsApp and Instagram really work without a VPN?
Yes. Travel eSIMs from AeroSims and Holafly route data through non-mainland gateways, so blocked services work normally. This does not apply to hotel Wi-Fi or local Chinese SIMs.
Do I need to register or show a passport for a China eSIM?
No. Data-only travel eSIMs require no ID. Passport registration applies to physical SIM cards bought locally in China.
Is the data truly unlimited on AeroSims?
AeroSims advertises no daily cap and no throttling for its mainland China plan. Holafly’s plan carries a fair-use policy without a published threshold.
Can I use the same eSIM in Hong Kong or Macao?
The unlimited mainland plan covers mainland China only. For combined itineraries you have two AeroSims options: matching unlimited plans per territory, or one fixed data package covering mainland + Hong Kong + Macao together (from $7.90 for 3 GB). See our Macao comparison for that leg.
When do my travel days start counting?
On arrival. The plan activates when the eSIM first connects in China, not at purchase — install it before you fly.
