Pay-per-use cost audit
How much AT&T charges per hour in China without a plan
Here is how the first morning in China plays out on AT&T pay-per-use (no plan active). You wake up, open Google Maps to find coffee nearby (~50 MB). You check email and a few attachments load (~5 MB). You scroll Instagram for 15 minutes while you wait (~20 MB). That totals 75 MB. At $2.05/MB, your first morning costs $154 before 9 AM. A 5-minute FaceTime call to confirm plans adds $154. By noon, after another hour of navigation, the bill reaches $410. These are AT&T's published pay-per-use charges.

Network coverage
China network operators and coverage map
China runs one carrier: China Unicom. AT&T and Verizon both roam through China Unicom at $10/day. An eSIM connects to the same China Unicom infrastructure at $1.08/GB. AT&T pays China Unicom a wholesale rate and resells access to you at $10/day. The eSIM sells the same access at $1.08/GB. 5G is live on China Unicom's network in China. AT&T's roaming pass delivers that 5G signal at $10/day. A travel eSIM delivers the same 5G signal at $1.08/GB — no speed penalty for switching. China has widespread 5G coverage. World's largest 5G network with 3.5M+ base stations; covers all major cities and many rural areas Average download speeds reach 180 Mbps on China Unicom's network — identical whether you connect through a carrier roaming pass or a travel eSIM. Providers routing through China Unicom offer the best balance of speed and international service access.
China Unicom provided excellent 5G in Beijing, Shanghai, and Shenzhen. 4G coverage solid even in rural Yunnan and Guizhou.
Pricing breakdown
What you pay for data in China — carrier vs eSIM
How much does China roaming cost over 14 days? AT&T: $140. Verizon: $140. T-Mobile high-speed: $210. A 10GB eSIM on China Mobile: $10.80. The difference between the cheapest carrier option and the eSIM is $129.20 less than AT&T.
Each day AT&T connects you to China Mobile in China costs $10. Buy a 10GB eSIM plan at $10.80 and that same daily access drops to $0.77/day. Over 14 days, the difference is $129.20. Local SIM at $10 for 20GB is cheap but means no Google Maps, no WhatsApp. Travel eSIM at $3.49/day includes firewall bypass.
eSIM pricing for China: 1GB at $3.49 ($3.49/GB), 3GB at $9.49 ($3.16/GB), 5GB at $13.99 ($2.80/GB), 10GB at $23.49 ($2.35/GB), 20GB at $35.99 ($1.80/GB). AT&T's 14-day roaming bill is $140 regardless of data consumed. Unlimited eSIM data costs $48.86 for the same period, $91.14 less. China eSIM prices are mid-range but include the invaluable benefit of firewall bypass — worth the premium over local SIMs. Travelers in China average 1.5GB of mobile data per day, so a 14-day trip needs roughly 21GB.
Trip cost breakdown
Weekend, two-week, and month-long trips to China: carrier vs eSIM
Three days in China costs $30 on AT&T at $10/day. A 2GB eSIM on China Mobile covers the same period for $9.49. Difference: $20.51.
Fourteen days costs $140 on AT&T — more than many flights to China. A 20GB eSIM on China Mobile covers 15GB of photos and video calls for $35.99. Difference: $104.01 (74%).
Thirty days on AT&T costs $300. A 50GB eSIM on China Mobile covers 50GB for $68.39. Difference: $231.61 over the month. AT&T rate: $10/day regardless of data consumed. Rates checked June 2026.
Airport options
Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX): SIM card vs eSIM cost
Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX)'s SIM counters require passport scanning under China's telecom regulations. Passport or ID is required for SIM registration. China Mobile and China Unicom and China Telecom handle this on-site, adding 20-40 min; real-name verification process to your post-flight process. A travel eSIM requires no in-country registration at point of purchase. You get 1GB on China Mobile for $3.49 — no passport submission needed. Local shops charge $8-15 for 5-20GB / 30 days with the same registration requirement.
Local alternative
Local SIM vs eSIM in China
A local SIM in China costs $8-15 for 5-20GB / 30 days at China Mobile and China Unicom and China Telecom, need a passport for registration. The in-person registration adds 20-40 min; real-name verification process to your arrival process. A travel eSIM at $3.49 requires no passport submission and no counter wait. Both options connect to the same China Mobile network.
Data planning
How to plan your data for 8 days in China
One hour of video streaming consumes about 1 GB. Two hours/day of streaming in China uses 2 GB daily, more than 1.5GB average usage. For a 8-day trip with occasional streaming, budget at least 12GB. Good WiFi in hotels and cafes reduces your mobile data needs.
A 20GB eSIM costs $35.99 for 8 days. AT&T charges $80 for the same trip on the same China Mobile towers. For heavy data users, unlimited daily plans start at $3.49/day — still cheaper than any carrier roaming pass.
Connectivity
WiFi availability in China
Free WiFi in most hotels and cafes; many require Chinese phone number for login Cafe WiFi networks in China are open networks without encryption. They work for basic browsing, but avoid logging into banking or work apps on public networks. A travel eSIM on China Mobile provides a private connection for any sensitive app you use while out.
Plan your data
How many GB you need for China
AT&T and an eSIM both connect to China Mobile's towers in China. AT&T charges $10/day for that connection. An eSIM charges $1.08/GB. At typical daily usage, AT&T's rate is 6x higher per gigabyte.
China has one mobile operator: China Unicom. US carriers pay China Unicom for roaming access and pass that cost to you at $10/day. An eSIM connects to China Unicom directly at $1.08/GB — no carrier markup.
Airport SIM counters at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) charge $15-30 for 3-10GB / 7-30 days after a 20-40 min; real-name verification process wait — still more than a 20GB eSIM at $35.99. Local prepaid SIMs in China run $8-15 for 5-20GB / 30 days, requiring an in-person stop and sometimes a passport copy. An eSIM at $35.99 skips that entirely. Prices stable; tourist plans slightly more expensive than local plans
Quick reference
China Travel Essentials
110/120/119
110, 120, 119 are the emergency numbers in China. Different numbers may route to different services — save all of them before your trip. Emergency calls work from any mobile device, including travel eSIMs.
Type A/C/I
US plugs (Type A flat two-prong and Type B three-prong) fit China's outlets directly. No adapter is needed for phones, laptops, or standard US electronics. Voltage is 120V — compatible with dual-voltage US chargers.
CST (UTC+8)
CNY (¥)
Tap-to-pay (Apple Pay, Google Pay) is accepted at most stores and restaurants in China. Visa and Mastercard work at virtually all merchants. Carry a small amount of local CNY for markets, taxis, and small vendors that do not have card readers.
Good to know
Average data consumption in China runs around 1.5GB/day for typical tourist use. Map downloads, streaming, and video calls are the biggest data draws. Buy one size larger than your estimate — topping up mid-trip often costs more per GB than the original plan.
Quick tip
China requires passport-based SIM registration for physical SIMs. A travel eSIM bypasses this requirement entirely — no paperwork, no waiting.
Step by step
How to cut roaming charges on a China trip
- At the airport before departure: if Settings > Cellular shows an "Add eSIM" option, your phone is ready — buy and install a China plan in under 5 minutes on any airport WiFi
- Airalo offers the China 1GB plan for $3.49 — buy it directly from their app or website. Compare all eSIM providers to find the best option for your trip.
- Open your phone's eSIM settings and scan the QR code — do this before your flight to Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) so it activates the moment you land
- Turn off Data Roaming (Settings > Cellular on iPhone, or Connections > Mobile Networks on Android) to stop carrier charges. Read the full how-to-turn-off-data-roaming guide for device-specific steps.
- On iPhone at Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX): tap Settings > Cellular, select your Airalo eSIM line, and set it as the active data SIM — China Mobile's 5G signal appears in the status bar within 30 seconds
- On Samsung Galaxy: go to Settings > Connections > Mobile Networks > WiFi Calling and enable it on your home SIM — calls route over the eSIM data connection in China
Data tips
China app and data usage guide
Travel booking apps — flights, hotels, and train tickets — typically use 5-20 MB per search session. If you book in-country transport while in China, plan for one session of 15-30 MB. Download booking confirmations to your phone over WiFi so you can access them without cellular data.
Regional context
How China compares to other Asia destinations for data
A few things to know before turning off carrier roaming in China:
Great Firewall blocks most VPN services; only government-approved VPNs technically legal; travelers should install VPN before arrival This applies equally to carrier roaming and eSIM connections — switching from roaming to eSIM does not change your VPN access in China.
China SIM registration: Strict real-name registration with passport; in-person verification at carrier store required. A travel eSIM purchased abroad bypasses local SIM registration requirements at the point of sale.
Google, WhatsApp, Facebook, Instagram, YouTube, and most Western apps are blocked by the Great Firewall
WeChat and Alipay are essential for payments — but foreign card linking is now easier since 2024 reforms
Travel eSIMs from providers like BitJoy route data through foreign servers, bypassing the Great Firewall
Install VPN and all necessary apps BEFORE arriving — VPN websites and app stores are blocked inside China
Golden Week (October 1-7) sees 800+ million domestic trips — avoid this period for less crowded tourism
Free WiFi in most hotels and cafes; many require Chinese phone number for login Roaming passes charge $10/day to fill WiFi gaps. An eSIM covers the same connectivity at $1.08/GB.
Travel eSIMs that route through foreign servers are the only way to access Google/WhatsApp without a VPN in China.
Spring and autumn offer best weather; avoid Golden Week (Oct 1-7) and Chinese New Year for extreme crowds
Forgot your eSIM?
Buying an eSIM after you land in China: what it costs
You landed in China without an eSIM. Here is what that costs and what you can still do.
All four major providers — Airalo, Holafly, Saily, and Nomad — allow post-arrival purchase and installation over WiFi. You do not need a local SIM to buy an eSIM. Beijing Capital (PEK) / Pudong (PVG) / Daxing (PKX) has free WiFi in the arrivals hall. Connect there, open Airalo or Holafly, and install a 1GB plan at $3.49 before you leave the terminal. If airport WiFi is unavailable, hotel lobby WiFi works as a fallback — most front desks in China give you the password at check-in. Last resort: turn on carrier data long enough to download the eSIM provider app (~5 MB, roughly $10 on AT&T pay-per-use), then switch to the installed eSIM immediately. That one-time charge is far below a full day at AT&T's $12/day rate.
China FAQ
China eSIM & roaming questions
How much does carrier roaming cost in China?
T-Mobile includes China in its free international plan, but throttles every connection to 256 Kbps — one-eighth the speed of basic 2G. AT&T costs $10/day, Verizon costs $10/day. A travel eSIM on China Mobile at $3.49 for 1GB provides full 5G — the same towers, none of the speed cap, and less money than either paid carrier option.
Is T-Mobile's free international data fast enough in China?
No. T-Mobile caps free international data at 256 Kbps in China — one-eighth the speed of basic 2G. At that rate, Google Maps takes 15+ seconds to load a single tile and will not work for navigation. Streaming video requires at least 1.5 Mbps; video calls need 2 Mbps. Basic WhatsApp text messages work, but anything else does not. T-Mobile's high-speed add-on for China costs $15/day. A travel eSIM on China Mobile's 5G network delivers full local speeds at $1.08/GB — cheaper per GB than the speed upgrade.
How is my roaming bill calculated in China?
Your carrier uses one of two models. Per-day billing: AT&T charges $10 and Verizon charges $10 for each calendar day your phone connects in China — even if you only check a notification at midnight. Per-MB billing: without a day pass, AT&T charges $2.05 per megabyte, which adds up to $2,099 per GB. Both models penalize casual background data usage. A travel eSIM uses flat-rate billing — you pay 1GB for $3.49 upfront, with no per-day activations and no per-MB overages. Once purchased, the cost is fixed regardless of usage patterns.
How do I avoid roaming charges in China?
Turn off data roaming on your carrier SIM before you land in China. Buy a travel eSIM from a provider like China Mobile starting at $1.08/GB and install it via QR code before departure. The eSIM handles all data on 5G local networks while your carrier SIM stays active for calls and texts through WiFi Calling. This setup eliminates roaming charges entirely. Without these steps, AT&T charges $10/day and Verizon charges $10/day the moment your phone touches a China tower.
How do I set up a dual-SIM Android phone for China?
On Android, go to Settings > Network & Internet > SIMs. Your physical home SIM and the travel eSIM for China appear as two separate SIM slots. Set the eSIM as the default for mobile data. Set your home SIM as the default for calls. Enable WiFi Calling on your home SIM to keep your number active for free over WiFi. The eSIM connects to China Mobile's 5G network at $1.08/GB. With data roaming disabled on your home SIM, AT&T's $10/day and Verizon's $10/day fees cannot trigger. Steps vary slightly by manufacturer — Samsung, Google Pixel, and OnePlus all use this core settings path. Rates checked June 2026.
Which US carrier has the best roaming deal for China?
None of the three US carriers offer a genuinely good deal in China. AT&T: $10/day. Verizon: $10/day. T-Mobile: free at 256 Kbps (unusable for navigation), $15/day for full speed. A travel eSIM on China Mobile starts at $1.08/GB — a 7-day trip at average usage costs $11.34 versus $70 for AT&T. No carrier matches the eSIM on per-GB cost.
Can I use a VPN with my eSIM in China?
VPN access in China is blocked. Great Firewall blocks most VPN services; only government-approved VPNs technically legal; travelers should install VPN before arrival A travel eSIM using international routing may provide different access than a local SIM, but results vary by carrier path. Neither roaming nor an eSIM guarantees unrestricted VPN access in China — download and configure your VPN before departure.
Do local apps in China require a local SIM or does an eSIM work?
Most local apps in China — ride-hailing, food delivery, transit — do not require a local SIM number to function. They require only a data connection, which a travel eSIM provides at $1.08/GB on China Mobile's 5G network. Some banking and two-factor authentication apps require a local phone number for SMS verification. For those cases, keep your home SIM active alongside the eSIM — your home number handles SMS while the eSIM handles data.
Is one eSIM enough for a multi-country Asia trip that includes China?
Multi-country Asia eSIM plans exist and cover many combinations — Japan, South Korea, Thailand, Singapore, and others in a single data bucket. AT&T and Verizon charge $10/day in each country separately, so a 3-country trip at 3 days each costs $90. A regional Asia eSIM for the same 9 days runs $15-$40 total. Check plan coverage maps — China may be included in a regional plan, or you may need a China-specific plan plus a regional one.
How much does carrier roaming cost for a week in China?
AT&T: $70/week (International Day Pass at $10/day). Verizon: $70/week (TravelPass). T-Mobile: free at 256 Kbps or $105/week for usable speed. The cheapest eSIM for China starts at $1.08/GB on China Mobile's 5G network — better per-GB value than all three carriers.
Fact check
3 roaming myths that cost travelers money in China
eSIM drains more battery than a physical SIM
An eSIM is a programmable chip embedded in your phone's hardware — the same radio module that handles physical SIM cards. It draws no additional power beyond what a physical SIM uses. Battery drain in China is driven by signal strength and data activity, not by SIM format. Weak signal forces your radio to search harder — that is the actual drain variable regardless of SIM type.
A VPN eliminates roaming costs
A VPN changes the routing of your data packets — it does not change which cellular network your phone connects to. In China, your phone attaches to China Mobile's towers whether or not a VPN is active. AT&T still bills $10/day for that connection even when you tunnel traffic through a VPN server. A VPN also adds 10–20% overhead to your total data consumption on top of the carrier charge.
eSIMs use different, slower networks
A travel eSIM in China connects to the same China Mobile towers as AT&T and Verizon roaming. The radio frequency bands, signal strength, and 5G speed are identical. AT&T's roaming agreement with China Mobile and a travel eSIM provider's agreement with China Mobile both access the same physical infrastructure. No speed penalty exists for switching from roaming to eSIM.
Our recommendation
eSIM vs roaming in China: the price gap
For China, Saily is the strongest fit. VPN usage is blocked in China, and Saily includes NordVPN-grade encryption on every plan. That keeps your browsing private on public WiFi and hotel networks. Plans on China Mobile start at $3.49 for 1GB. Holafly is the alternative if you need unlimited data — plans start at $2.99/day with no data cap.
7 days in China: $69 difference between carrier roaming and eSIM
eSIM data in China starts from $1.08. AT&T roaming starts from $10/day.
