Is 3BB down right now?
This page follows live 3BB status and 3BB down reports sent in by home fibre users across Thailand. Reports cover the 3BB Member app and the member website. A sharp rise in reports points to a fault on the 3BB side, not your router.
On a normal day the app opens on your bill at once. Trouble starts when the bill page spins, the QR code fails or sign in loops back to the start.
Is 3BB down for me or everyone?
Open the Member app on mobile data, then try the member website on your home Wi-Fi. If both fail and other 3BB homes near you see the same fault, a 3BB outage is likely under way. If a neighbour on 3BB gets in, the fault sits with your member login, your app copy or your bill data.
How do you pay a 3BB bill in the Member app?
Open the app, sign in as a member and pick the bill screen. The app shows the amount due and builds a QR code you scan with your bank app. A barcode on the same screen works at counters.
Members with two fibre lines hold two accounts under one login. The switcher at the top of the bill screen moves between them. If the second stays missing, sign out and back in.
What changed for 3BB sign in under AIS?
3BB now sits inside the AIS group, and member accounts are moving into AIS systems step by step. Some members get pushed towards AIS sign in channels, while the old member login still works for others. Mixed screens are normal during the move.
When does the member site block a visit?
The member website guards accounts by location, and visits from abroad often fail to open. Travellers hit a blank page or a payment error at the QR step. A Thai network route loads the same screens. Paying ahead avoids the block.
Checking your plan and add-ons inside the app
The Member app lists your current plan, its price and the add-on packs on your line. A plan change takes effect from the next bill round. Run a wired speed test on a computer before you judge a slow night.
Common 3BB Problems and Fixes
Most 3BB Member faults clear with a fresh sign in, a clean app cache or a switch of network. Work through the checks below in order. Each one targets a single fault on the app or the member website.
Member app refuses your password at sign in
Check the member ID on your latest bill. The app takes the member login, not the router login name. Reset the password and type it in by hand.
Bill payment fails at the QR code step
Let the app build a fresh QR code instead of reusing a saved screenshot. Scan it while the code is still live. An old code dies and the payment never starts.
Second fibre account never shows in the app
Use the account switcher on the bill screen for the second line. Pull down to refresh the list. If it stays hidden, sign out, clear the cache and sign in again.
App signs you out again and again
A login loop often follows an update with an old saved session. Clear the app data and sign in fresh. Turn off any VPN first, since the member system rejects odd routes.
Bill amount in the app looks wrong
Compare the app total with the bill detail screen, not the home tile. Plan changes land on the next bill round. If a paid bill still shows as due, wait a day.

Frequently Asked Questions
How do I pay my 3BB bill without the paper bill?
Open the 3BB Member app and sign in with your member ID. The bill screen shows the amount due with a QR code and barcode. Scan the code with your bank app or show the barcode at a counter.
Is 3BB down in my area right now?
Check the live reports on this page first. A fast rise in 3BB down reports points to a wider fault. If reports stay flat, restart your router and test the member site on mobile data.
Can I manage a 3BB account inside myAIS?
Some 3BB accounts now appear inside myAIS after the move under AIS. Many members still use the Member app and website. If your line is missing in one app, try the other first.
What login does the 3BB Member app want?
The app wants your 3BB member ID and member password. It does not take the router login name with the @3bb suffix. That name belongs to the fibre connection itself.
Does the 3BB member site open from abroad?
Often it does not. The member website blocks many visits from outside Thailand, and the QR step fails there too. Use a Thai network route or the app on a Thai SIM instead.
Why does my app show the wrong bill total?
The home tile can lag behind the bill detail screen after a plan change. Add-ons and part month charges land on the next bill. Open the detail screen for the true amount before you pay.
