Are Taiwanese mobile proxies on Chunghwa Telecom worth it for app testing?
Yes, for anything your app's servers decide from the IP, and no for what depends on the phone or the SIM. ProxyField's 59K+ Taiwanese mobile IPs run on the Chunghwa Telecom network, over 5G, 4G and LTE, with under 1.5 s typical response for mobile, according to our service data. They cost $3.45/GB for 1 GB (about 10,000 API calls at 100 KB), $3.29 from 10 GB, $2.99 from 100 GB and $2.45 from 1,000 GB. Chunghwa Telecom is the mobile network listed for the Taiwan pool. Check the network of every IP you test with in the org field (steps below).

|---|---|
| A Taiwanese mobile IP on the Chunghwa Telecom network, as your servers and third-party APIs see it | GPS and device location |
| Localized content, prices and currency chosen by IP | SIM identity, SMS and phone-number checks |
| Login, sign-up and checkout flows, as far as their risk checks look at the IP | App-store region, which follows the store account |
| API responses, ad landing pages and geo-blocking by IP | Radio latency, signal strength and handoffs between 4G and 5G |
| How rate limits and IP-reputation rules tend to treat a carrier IP | Push notifications and carrier billing |
When a real Taiwanese SIM is needed: SMS codes and phone-number sign-up, carrier billing and payments tied to the line, push delivery on the carrier network, and anything that reads GPS. Use a test phone with a local SIM for those, and the proxy for the repeatable IP-based tests around them.
What a test costs. 1 GB of mobile traffic is $3.45 with the Easy Trial, about 10,000 API calls at an example 100 KB each. The traffic never expires, so a test that stops halfway keeps the rest.
Pass or fail, in five steps:
- Route the device or emulator through
gate.proxyfield.io:7000(Android, iOS) with a Taiwan line and a sticky session:<login>-country-tw-session-app01-ttl-3600(one IP for an hour). The carrier is not a targeting option. Mobile or residential in the username: residential by default; add-mobileafter the login for mobile IPs, as in<login>-mobile-country-us. - Log the exit 20 times through the same session, 5 seconds apart:
for i in $(seq 1 20); do
curl -s -x gate.proxyfield.io:7000 -U "<login>-country-tw-session-app01-ttl-3600:<password>" https://ipinfo.io/json \
| python3 -c 'import json,sys; d=json.load(sys.stdin); print(d.get("ip"), d.get("country"), d.get("org"))'

TW, the same IP, and a Chunghwa network inorg. Chunghwa Telecom's main network, AS3462, is registered as "Data Communication Business Group" (bgp.he.net: AS3462), so a pass reads like203.0.113.24 TW AS3462 Data Communication Business Group(the IP here is a documentation example). Fail: another country, an IP that changes inside the session, or anorgthat names a network other than Chunghwa Telecom's, such as a fixed-line or hosting company. If the exit node drops, the gateway retries once with a new session, so the IP can change; an IP idle for 120 s is replaced. Log the IP at each step of the app test. - Set the device to the Taipei time zone and Traditional Chinese, and test the app's own location features on a real device.
- Compare the app's answers through the proxy with your own country's: prices, content and API responses that change are the ones the Taiwan IP decides.
See mobile proxies for the protocols and sessions, which are the same as residential, on one balance.
