How do I transfer my number to Belong?

Want to join Belong and bring your mobile number with you? (Also known as ‘porting’ to the telephone wonks out there.) No sweat – here’s everything you need to know.

No data plan transfers

We can’t transfer data plans from other providers over to Belong. The good news is that our new data plan SIMs are free and we send them right to your door: here’s how to start a new data plan service.

What you’ll need

When you activate your Belong SIM, you’ll need a couple of extra details handy to make sure we can transfer your mobile number from your old provider:

  • You’ll need the mobile number you’re transferring.

  • If you’re transferring from a prepaid service (where you pay upfront), you’ll need your date of birth.

  • If you’re transferring from a postpaid service (where you pay for what you used that month), you’ll need your account number, which should be on your bill.

Getting your number transferred

When you activate your Belong SIM, we’ll ask if you want a new number or if you want to keep your old one.

If you want to keep your number, just fill in the details and hit Send verification code – we’ll send you a verification code by text to make sure that it’s really you asking to transfer your number. Enter the code we sent you and we’ll get the transfer done.

How long does it take?

Transferring a number usually takes less than four hours, but it can take up to 36 hours if you’re transferring your number on a Sunday or a public holiday.

We can only transfer numbers while our offices are open. So you can plan your move with military precision, here’s the rundown on our operating hours:

Monday to Friday: 8am–8pm (AEDT)
Saturday: 10am–6pm (AEDT)
Sunday: closed
Easter Monday and the Queen’s Birthday: 10am–6pm (AEDT)
All other public holidays: closed

Problems with transferring your number

If you’ve waited out your transfer time – which can be up to 36 hours over Sundays or public holidays – and you still haven’t heard anything, call us on 1300 235 664 so we can check it out.

If there was a problem with getting your number transferred, you’ll get an email from us letting you know what happened and why.

What to do if your details don’t match

More often than not, number transfers fail because the date of birth or account number Belong has been given doesn’t match the details held by the previous provider.

If this happens, it’s a simple fix: just check the details you’ve given us, and double-check they line up with the details on your previous account. Once the discrepancy’s been fixed, we can try the transfer again.

Just log in to your Belong account -  you’ll see a ‘transfer failed’ update under your new mobile service. Just hit the ‘Update details’ button to edit your details, so we can retry the transfer.
