Duolingo Mobile Proxies: US Pricing and Pages on a Real SIM

Duolingo is a mobile-first product with a web version. Its prices for Super Duolingo and Duolingo Max differ by country, its course list depends on the language of the interface, and its marketing pages change by region. A product team in Vietnam that builds a language app, a school in China that uses Duolingo for Schools with American partner classes, or a marketing team that runs US campaigns about language learning, all need the American view. American Mobile Proxies gives a real US carrier SIM, so Duolingo sees a phone user in the United States and shows the American version of every page.

What an American visitor sees on Duolingo

The Duolingo website and app read the visitor's region to set the price of Super Duolingo, the family plan, Duolingo Max and the yearly offers. The prices are shown in US dollars for an American visitor and are often different in amount, not only in currency, from the prices in Asia. Course availability also depends on the interface language. An English speaker in the United States sees the full list of courses from English, including the Vietnamese and Chinese courses that many of our customers care about. The landing pages for the Duolingo English Test and for Duolingo for Schools are tuned to the US market.

Product research and pricing comparisons

Teams that build or sell language learning products compare their offer with Duolingo's US offer. Open the subscription page from an American SIM, record the monthly and yearly prices, the free trial length and the features listed. Repeat weekly to see when Duolingo changes the offer. The web pages are public and the task is ordinary reading, so pace it like a person and do not pull private user data. Use rotation between passes if you want each pass to look like a separate visitor; our lines rotate by link, by API, from the dashboard or on a timer.

Localisation QA for Chinese and Vietnamese

Duolingo offers courses for Chinese and Vietnamese speakers and courses in Chinese and Vietnamese for English speakers. A localisation tester needs to compare the US English interface with the translated one. The simplest way is two browser profiles: one on an American SIM with the interface in English, one on your own connection with the interface in your language. Walk through the same lesson in both, note the strings that differ in meaning, and report them. The SIM keeps the American side stable for the whole project.

Schools, teachers and American partner classrooms

Duolingo for Schools lets a teacher create a classroom and assign lessons. A teacher in Asia who runs a joint program with an American school wants to see the classroom tools as the American teacher sees them, with the same assignment names and the same due dates. Due dates follow the browser time zone, so set the profile time zone to the SIM's city. Boston, New York, Miami and North Carolina are Eastern time. Chicago and Houston are Central. Phoenix is Mountain. Los Angeles is Pacific. Sign in to your own teacher account only, from the same SIM each time, with the address kept sticky.

Ad verification and what not to do

Agencies that run language learning ads in the United States, including ads that compete with Duolingo or that promote Duolingo-related tutoring, check that their ads are served to a US mobile address and that the landing page after the click is the US one. A carrier SIM in the target city is the honest way to see what a real American phone user sees. Keep ad clicks to real verification, never to inflate numbers.

Do not use the SIM to open many Duolingo accounts, to farm streaks or leaderboards, or to take the Duolingo English Test from a false location. The test is proctored and its rules are strict. We do not support that use and Duolingo will cancel the result. Buy a 4G line for $6 a day, $30 a week or $68 a month, or 5G for $7, $33 or $78, pay with USDT TRC-20, other crypto, cards, PayPal, Zelle or wire on request, and use it for honest research, QA and your own classroom work.
