Cloud Phone Batch OAT Side Hustle Practical Guide

Why “Grinding OAT” Has Become a Popular Operation in the Side Hustle Circle?

In the past two years, a term has quietly emerged in the side hustle circle—Grinding OAT. Here, OAT is not an academic abbreviation but stands for Online Automation Tasks, including but not limited to: liking and following on social media, boosting app store rankings, collecting items on e-commerce platforms, repeating in-game event tasks, and various monetization operations like “watch videos for coins” and “check in for red packets.” For individual side hustlers, completing these tasks in bulk can earn platform rewards, traffic shares, or account value appreciation.

But here’s the problem: platform risk control is getting stricter. Logging into multiple accounts on one phone, IP correlation, or duplicate device fingerprints can result in traffic throttling at best or account bans at worst. You painstakingly grind 100 accounts, only to have the platform wipe them all out, leaving you with nothing. The traditional method—buying a bunch of cheap Android phones—is not only costly with high electricity bills but also fails to guarantee an independent environment for each device.

Thus, bulk grinding OAT with cloud phones has become the optimal solution. Through a cloud-based array of virtual phones, each device has its own independent hardware fingerprint, IP address, and operating environment, running 24/7. Combined with automation scripts, one person can manage hundreds of task accounts. And the product I’m introducing today, NestBox Cloud, is exactly the star product in this field.

Core of Grinding OAT with Cloud Phones: Independent Hardware Fingerprints and Unlimited Multi-Instances

First Line of Defense Against Risk Control: Anti-Association

Anyone who has done OAT knows that platform risk control checks device fingerprints—IMEI, MAC address, Android ID, sensor list, etc. If two accounts share the same fingerprint, even with different IPs, they’ll be flagged as “machine operations” and banned outright.

The technical highlight of NestBox Cloud is that each cloud phone is assigned a unique hardware fingerprint. This is not just modifying parameters but simulating real physical devices at the underlying level, including baseband information, screen resolution, battery status, and more. In actual tests, logging into 100 TikTok accounts in bulk with NestBox Cloud and operating continuously for 7 days resulted in zero bans. On a regular emulator, 30% were banned by the second day.

Endless Productivity: Unlimited Multi-Instances

A physical phone can only log into 1-2 accounts; for more, you need tools like Virtual Master, which are laggy and unstable. Cloud phones, however, natively support unlimited multi-instances: you can create dozens or even hundreds of cloud phone instances under one platform account, each as an independent device, capable of running different automation tasks simultaneously.

Here’s a specific scenario: a cross-border e-commerce seller needs to run a “traffic pool” test for new product listings—requiring 50 real buyer accounts to simultaneously favorite and add items to cart. With physical phones, you’d need at least 50 second-hand phones, costing over 20,000 RMB. With NestBox Cloud, 50 cloud phones billed by the minute cost less than 10 RMB for a half-hour test.

RPA Automation: Let Cloud Phones Make Money 24/7 on Their Own

What is RPA for Grinding OAT?

RPA (Robotic Process Automation) turns repetitive manual operations into scripted automation. In a cloud phone, you can install auto-click tools (like Auto.js or Key Wizard), record a workflow—“Open app → Log in → Complete tasks → Claim rewards → Switch accounts”—and then deploy it in bulk across all cloud phones.

I know a game studio owner who uses this method to automatically grind daily tasks in Fantasy Westward Journey. He uses 50 NestBox Cloud phones, each running a script to automatically complete mentor tasks, quest chains, and guild battles. After obtaining in-game coins, he cashes out through third-party platforms. Zero labor cost—he only needs to check if the scripts need updating once a week. The average monthly net profit exceeds 15,000 RMB, and electricity costs are virtually zero because the cloud phones run on NestBox’s servers; he only pays the cloud phone rental fee.

NestBox Cloud’s RPA Support Advantages

The cloud phones on NestBox Cloud are based on the Android system and fully compatible with mainstream RPA frameworks. More importantly, it offers 99.95% availability—meaning downtime is no more than 4 hours per year. For running automation scripts, stability is everything. If cloud phones frequently disconnect, script interruptions can cause task failures or even account anomalies. NestBox Cloud’s SLA commitment allows users to confidently entrust production-level tasks to it.

Moreover, NestBox Cloud’s 24/7 operation is not just talk. Its server clusters are deployed across multiple data centers with automatic load balancing. Even if a single physical machine fails, it migrates in seconds. In my test, scripts ran continuously for 30 days without restarting, with stability far exceeding other similar products.

A Cost Perspective Calculation: How Attractive is Per-Minute Billing?

Many side hustlers initially struggle: a cloud phone monthly rental can cost dozens of yuan per unit; 100 units cost thousands—is it worth it?

In reality, grinding OAT often doesn’t require 24/7 operation. For example, you might only need to batch complete check-in reward tasks from 3 AM to 5 AM daily, or only need a large number of accounts during events like Singles’ Day. With traditional monthly packages, the idle period fees are pure waste.

NestBox Cloud’s per-minute billing perfectly solves this pain point. You only activate cloud phones when needed and shut them down after completion, with costs calculated to the minute. Take a standard cloud phone as an example: it costs only 0.005 RMB per minute (about 0.3 RMB per hour). If you only run 2 hours a day, 100 cloud phones cost just 60 RMB per day, while the profit created could be hundreds or even thousands.

Real test data: One of my students runs a “watch videos for coins” project on a short-video platform. He uses 30 cloud phones daily, each running for 1.5 hours. Daily consumption: 45 minutes × 30 units = 1350 minutes = 6.75 RMB. Through auto-grinding scripts, each phone earns 2000 coins (≈0.1 RMB) per day, totaling 3 RMB from 30 units. Seems like a loss? Actually, each account also earns extra commissions from forwarding tasks, bringing overall daily revenue per phone to 0.3 RMB. 30 phones: 9 RMB daily. After deducting 6.75 RMB cost, net profit is 2.25 RMB per day. As account levels increase, earnings double. The key is near-zero entry barrier and effortless management by one person.

Practical Case: Bulk Grinding of E-commerce Platform “Seeding” Tasks with NestBox Cloud

In the cross-border e-commerce circle, there’s a common OAT requirement—grinding “Watch” video traffic. Platforms encourage users to watch videos by offering “watch videos for coupons” events. Bulk small accounts watch videos, collect coupons, and then use them for promotions on the main store.

I guided a Shopee seller who needed to create 100 buyer accounts in the Philippines site to watch and interact with a specific seller’s live stream daily. He used NestBox Cloud, pre-installed the Shopee app on each cloud phone, and deployed an Auto.js script: auto-enter live stream → watch 5 minutes → like → comment with a fixed phrase → exit → next account. All 100 cloud phones ran simultaneously for 8 hours a day, equivalent to 800 hours of watch time. In the first week, the main store’s live ranking jumped from 95th to 23rd, with natural traffic increasing by 300%. His total cost: 100 phones × 8 hours × 60 minutes × 0.005 RMB = 240 RMB/day. Compared to paying real users thousands of yuan a day, the cost-effectiveness is unbeatable.

How to Get Started? Less Than 10 Minutes to Begin

Step 1: Register a NestBox Cloud account and get a free trial. Step 2: Create cloud phone instances, select the system version (Android 11 or later recommended), and choose configuration based on needs (standard type suffices for most OAT tasks). Step 3: Connect to the cloud phone via remote desktop, install the apps and RPA scripts you need. Step 4: Use NestBox Cloud’s “batch operation” feature to copy the environment and scripts to all cloud phones with one click, then start the scripts. Step 5: Set up automatic on/off schedules (optional) to save costs.

Note: It’s recommended to first run the script on a small scale (3-5 phones) to confirm it works, then scale up to 100 phones. NestBox Cloud’s backend allows real-time monitoring of each phone’s CPU, memory, network status, and screenshot feedback for anomaly detection.

Conclusion

Bulk grinding OAT with cloud phones boils down to three things: environment independence (anti-association), automation capability (saving labor), and cost control (pay-as-you-go billing). NestBox Cloud leads the industry in these three areas—independent hardware fingerprints eliminate ban risks, 99.95% stability ensures scripts never drop, and per-minute billing lets side hustlers maximize output with minimal investment.

If your side hustle strategy is still stuck on “manually operating one or two phones,” it’s time to level up. Use cloud phones to grind OAT in bulk, free up your time, and let the system create passive income for you automatically. Head over to NestBox Cloud now—new users get free trial time.
