About by.U

by.U is a mobile-first social networking app built to help you get online with less hassle. Instead of dealing with complicated plan options, you simply enter your budget to find the right data package and SIM card. From there, you can browse websites and download files, music, videos, and software anytime and anywhere—tailored to how you actually use your connection.

The app also runs regular promotions and birthday surprises. Just by joining in, users can collect rewarding prizes, including free data packages, so staying connected can be more budget-friendly.

As you renew your plan, you earn uCoins. These can be exchanged for data rewards, or used to upgrade your membership level to unlock even more gifts.

Key Features of by.U

Strong Telkomsel network

• by.U uses the Telkomsel network to deliver fast and stable internet across many areas in Indonesia.
• While you travel between locations, signal quality adapts to coverage, helping you keep using messaging, social media, or video streaming with fewer interruptions.
• This network setup supports everyday connectivity without requiring complicated configuration.

Full 24-hour quota

• Get a quota that works throughout the entire day without complicated day/night restrictions.
• by.U supports data use on 3G or 4G anytime, so your allowance doesn’t get split by time.
• It’s easier to manage usage for work, study, or entertainment since your quota is available whenever you’re online.

Flexible, budget-friendly packages

• Choose a plan that fits your needs and budget.
• The app highlights Best Deals, such as Super Kaget 7 GB for 14 days at Rp 15.000, or 11 GB for 14 days at Rp 25.000.



• You can adjust later if your usage changes, helping you keep spending under control.

Everything digital in one app

• Pick your own number, order a SIM, activate it, and manage credit and data all from one place.
• Multiple payment options are available in-app to make checkout match your routine.
• When ordering a SIM, there may be free shipping promos from time to time, which can reduce setup costs.
• This integrated process simplifies both initial setup and day-to-day management on Android.

What Makes by.U Stand Out

• The app interface is designed to be easy to navigate, so features are quick to access.
• New users can sign up and order a SIM directly in the app, making onboarding smoother.
• The experience is built for convenience—helpful for both new users and people already used to mobile internet.

With by.U, managing your internet subscription feels simpler than traditional mobile plan systems. The straightforward quota selection and the lack of overly strict rules help create a more beginner-friendly experience.

For connectivity, the app relies on the Telkomsel network, which supports more reliable internet access over a wide geographical area—especially helpful for frequent travelers or users in places where coverage can be inconsistent.

On top of that, by.U focuses on affordability. Because you can select specific data packages, you can tailor your internet usage to match your financial situation—an advantage compared with more rigid plans from traditional carriers.

User Reviews

• “I’m satisfied with the by.u operator. It has been upgraded again for the by.u team. Please fix the application—sometimes it has issues and won’t enter the menu; it just stays on the home screen...”

• “So far it’s great. Very good signal, and if maintenance happens, there’s an announcement beforehand. The only drawback is for people who aren’t used to buying data through apps—if there’s no data left, it can be hard to open the app to buy more. I recommended it to my father and he had that problem too. Still, it’s quite cheap for students, and the add-ons help save data and money. Hats off!”

• “Good app. The 10GB one-day quota is always useful in serious situations, and the internet works well most of the time. Please let users know that 1Mbps equals 1/8 MBps (the capital ‘B’ matters—it's a basic data term people often don’t want to learn). The only downside: it doesn’t always notify you about maintenance at midnight.”

• “Great provider and easy to set up for new users. I bought my SIM months ago and I’m still using it. I like that the interface is simple...”
