Hey there! Got a Sun SIM? You need to register it. It’s the law now.
I know, I know. One more thing to do, right? But here’s the deal—every phone user in the Philippines has to do this. Sun Cellular (which is now part of Smart) needs your info. Your ID. Your details. All to keep your phone working.
Think of the Sun registration SIM link as your ticket. Your way in. Without it? Your phone stops working. No texts. No calls. No data. Nothing.
Are you using Sun prepaid? Or maybe you’ve got one of those Smart-Sun-TNT combo numbers? Doesn’t matter. This guide helps you out. Step by step. Click by click.
We’ll cover everything in 2025. What the Sun is now. How to register online. What papers you need. How to check if you did it right. Plus all those questions you’re probably thinking about.
Ready? Let’s do this!
What Is Sun Cellular?
Remember Sun? That phone company from 2003? They changed everything! Unlimited texts. Unlimited calls. Everyone loved it.
But things changed. In 2011, PLDT bought Sun. Then they mixed it with Smart. Now Sun is part of Smart’s big family. Which means a better signal. Faster data. More places covered.
You still see the Sun name around. But really? It’s all Smart now. Same network. Same system. Same registration portal.
Ownership and Integration
So who owns what? Let me break it down:
Smart Communications runs the show. They’re in Makati City. PLDT is their boss—also in Makati. And Sun? They’re still around in name. Based in Quezon City. But they’re part of Smart now.
This merger thing? It started slow. By 2020, everything was together. Prepaid, postpaid, broadband—all under Smart’s roof.
What’s this mean for you? Simple. Your Sun SIM registers on Smart’s website. No separate Sun portal. Just one place for all.
The Sun SIM Registration Link
Here’s what you need: https://simreg.smart.com.ph
That’s it. One link for everyone. Smart users go there. TNT users too. And yes, Sun users as well.
Don’t look for a special “Sun only” link. It doesn’t exist. Everything happens on that one Smart portal. But don’t worry—it’s easy to use. Works on your phone. Works on your computer.
How to Register Your Sun SIM Online
Let’s do this together. Step by step.
Step 1: Open the Link
Go to https://simreg.smart.com.ph. Use any browser. Or scan those QR codes you see on posters.
Step 2: Enter Your Mobile Number
Type your Sun number. Like 0922-XXXXXXX. Click “Send OTP.” Then wait. A text is coming.
Step 3: Input the OTP Code
Got the text? Type that code. It proves the number is yours. Then you move forward.
Step 4: Fill Out Personal Information
Time for details. They need:
- Your full name (exactly like your ID says)
- When you were born
- Are you male or female?
- Where you live
- Are you Filipino or from another country?
Step 5: Upload a Valid ID and Selfie
Two things here. First, a clear photo of your ID. Second, a selfie. Just your face. Make it clear.
What IDs work? Lots! Passport. Driver’s license. National ID. SSS or GSIS card. Voter’s ID. PRC ID. Postal ID. UMID. NBI clearance. Senior card. Even school ID for kids (with parent help).
Step 6: Review and Submit
Check everything. Twice. Then hit Submit. You’ll see a “success” message. Plus you’ll get a text saying “Done!”
SIM Registration Requirements Summary
What do you need? Let me list it:
- Your Sun number
- The OTP from the text
- A valid ID
- A selfie
- Your address
- Your nationality
- Say “yes” to their privacy rules
That’s it. Not too bad, right?
For Postpaid Sun Users
Got postpaid? You might be done already. Smart probably registered you using your account info.
Want to check? Or update something? Go to https://simreg.smart.com.ph. Pick “Postpaid.” Enter your number. Follow the steps.
Changed your address lately? New ID? You can update those too. Just call Smart if you need help.
How to Check If Your Sun SIM Is Registered
Not sure if you’re registered? Three ways to check:
Online: Visit https://simreg.smart.com.ph. Click “Check Status.”
Text: Look for that confirmation SMS from Smart/Sun.
Call: Dial *888. Ask them directly.
If you’re not registered yet? Do it now. Before it’s too late.
Why SIM Registration Is Important
The government made a law. Republic Act No. 11934. Fancy name, simple goal.
They want to:
- Stop scammers
- Protect your data
- Make people responsible
- Keep everyone safe
No registration? Your SIM dies. Want it back? Register first.
Deadline for SIM Registration
They gave extensions before. But by 2025? Everyone must be registered. Smart, Sun, TNT—all of them.
Haven’t done it yet? Do it now! Or lose your number. Your load. Your data. Everything.
Sun SIM Registration for Foreigners
Not Filipino? No problem. You can register too.
Tourists need: Passport. Return ticket. Where you’re staying.
Residents need: Passport. Alien card (ACR).
Students need: Passport. School papers.
Workers need: Passport. Work permit. Job certificate.
Your SIM works as long as you’re here. Need to stay longer? Update your papers.
For Minors and Children
Kids under 18? They can’t register alone. A parent does it for them. Using the parent’s name. Parent’s ID. Plus proof they’re related. Like a birth certificate.
Sun SIM Registration for Business or Enterprise Accounts
Company SIM? Different rules. You need:
- DTI or SEC certificate
- Business permit
- ID of the person registering
- Letter saying they can register for the company
This keeps business lines legal. And traceable.
Troubleshooting and Common Issues
Things go wrong sometimes. Here’s help:
No OTP? Bad signal maybe. Or wrong number. Try again.
“Invalid ID format”? Photo’s blurry. Or wrong file type. Use clear JPG or PNG.
Page won’t load? Bad internet. Try Wi-Fi. Or wait and retry.
Wrong details? Typo maybe. Go back. Request an update.
SIM dead? Missed the deadline. Call Smart. They’ll help reactivate.
How to Update or Correct Information
Made a mistake? Changed something? Here’s the fix:
- Log in with your number
- Pick “Update Registration”
- Upload new ID and info
- Submit and wait
Smart checks it. Sends confirmation. Takes a few days.
Data Privacy and Security
Worried about your info? Don’t be. Smart keeps it safe. They follow the Data Privacy Act. Everything’s secure.
Your data? Only for verification. Legal stuff. Security. Never sold. Never shared for ads.
