How to - Find your Mobile Broadband number.png


Did you know that as a mobile broadband customer the SIM card in your modem or router has its own unique mobile number? It looks like a normal phone number, beginning with 083. Most importantly, your mobile broadband number is needed when registering your modem/router on My3. You’ll also be asked for it when you contact us with an account query, make a bill payment or top-up.


How do you find your number?

There are 5 ways to find your number, let’s take a look:


  • As a BillPay customer, you’ll find your broadband number on your contract. Check your email for a copy of this.
  • If you’re super organised and have the packaging your SIM card came in you’ll see your mobile broadband number printed on the back.




  • Have you got a bill? Take a look at the top section of any of your bills and you’ll see ‘Your Three phone number’




  • Open your modem/router home page  👉  or and login. Next, go to Advanced, System and then Device Information. In here you’ll see ‘My number’



  • The last option is to send your mobile a text message from your router/modem homepage. Please note, that you’ll be charged for a standard SMS as this isn’t included in your plan. Alternatively, pop your SIM into a phone and text MyNumber to 50272 and you’ll receive your number in response.
