Someone asks for your Indonesian number and you realise you've never actually looked at it. Or you're four days into the trip with no idea whether you've burned through your data. Both are a thirty-second fix, and neither needs an app.
The Short Answer
Dial *808# on your Telkomsel line to see your own Indonesian number — it appears on screen straight away, for a charge too small to notice. To check your data, send an SMS reading UL INFO to 3636; the reply comes back in Indonesian, but the numbers in it are readable at a glance. Neither needs an app or a login.
Finding Your Own Number
This is the one people need in a hurry, usually because a driver, a villa host or a shop assistant is standing there waiting.
- Open your phone's dialler, with the Telkomsel line selected if you're running dual SIM
- Type *808#
- Press call
Your number comes back on screen as a pop-up. There's a tiny charge for the request, deducted from credit — small enough that it's never worth thinking about, though it does mean a line with zero credit may not answer.
A couple of things worth knowing. If you're on dual SIM, the code runs on whichever line your dialler is set to, so check you haven't just asked your home carrier for its own number. And your Indonesian number will start +62 once you write it out internationally — locally people write it starting with a zero instead, so 0812… and +62812… are the same number.
If dialling fails entirely, your phone contacts or your own saved order confirmation will have it: we send your number by email when the line goes live.
Checking Your Data
The quickest way is a text message. Send an SMS reading UL INFO to 3636 from your Telkomsel line, and a reply comes back with what's left.
The reply is in Indonesian. That sounds like a problem and mostly isn't — the figures are the point, and a line reading something like Kuota 4,7 GB tells you what you need to know without translating a word. Kuota means your data, and the date in the message is when it runs out.
If you'd rather have a screen than a text, the MyTelkomsel app shows the same thing in a nicer layout. It's also largely in Indonesian, which is the running theme.
And if you'd rather just ask a person, message us on WhatsApp. We can look your line up from our side and tell you in plain English how much data you have and how many days are left. We'd honestly rather do that than have you decoding a menu on a beach.
Why Your Data Looks Like It's Vanishing
Before you conclude something's broken, two ordinary explanations account for most "where did it all go" messages we get.
Hotspot. Share your connection with a laptop and the laptop's updates, backups and video calls all come out of your data. Laptops are hungrier than phones. If you're running a hotspot, expect it to go faster than you'd think.
Video. Uploading a few days of photos, or an evening of scrolling video at full quality on hotel Wi-Fi that quietly dropped out, goes through more than people expect.
Neither is a fault. But both are worth checking before you assume your plan is wrong.
Running Low
If you're short on data but still inside your plan's dates, a top-up adds more. What it won't do is add days — the expiry date is set by the plan your number was registered on, and nothing extends it. We wrote about how the 30 days work separately, because the dates confuse more people than the data does.
So the order to check things in is: first how many days are left, then how much data. If you've got plenty of days and no data, top up. If you've got neither, you're looking at a new plan rather than a top-up — and worth knowing before you order: a passport and phone can only be registered twice in any 12 months, so a replacement plan isn't always available.
Quick Reference
| What you want | What to do |
|---|---|
| My own number | Dial *808# |
| Data left | SMS UL INFO to 3636 |
Both run on the Telkomsel line itself, so make sure that's the line your phone is using before you send or call.
