Unknown Cash, the in-game currency in PUBG Mobile, is quite expensive; not every player can afford it. UC is used to purchase unique skins and costumes from in-game shops, and also to buy the Royal Pass Elite and Elite plus.
The only legal way to get free UC in PUBG Mobile using an Android device is with the use of various 'Get Paid To' (GPT) apps.
On that note, here is a look at the various apps which you can use to get free UC in PUBG Mobile:
#1 Google Opinion Rewards
Google Opinion Rewards was made available in India quite a while ago. This app rewards the users with Google Play credits for answering surveys, and UC can be purchased using these credits.
The number of surveys differs from each person. The app has over 10 million downloads and is rated 4.3 on the Playstore.
#2 Easy Rewards
Easy Rewards is an app in which users can complete various tasks like downloading an app, answering surveys and answering quizzes, among other missions. Users earn coins which can be used for the purchase of Flipkart, Amazon and Paypal vouchers.
Players can then purchase Google Play gift cards using these vouchers. This app is rated 4.4 and has over 100 thousand downloads on the Playstore.
This app is quite similar to Easy Rewards, where you have to complete surveys to earn cash. The only downside is that PayPal cash is the only available way to claim the rewards. The app has over 1 million downloads and is rated 4.5.
Many websites offer a tool called UC generator and claim to provide free UC that can be used in PUBG Mobile. However, these tools are illegal, as the ToS of Tencent Games stipulates that topping up UC via an unauthorised channel is a violation of the guidelines.
