Getting Started

Thank you for choosing Tesco Mobile. Getting started couldn't be easier. 

Pop your new sim card into your phone. If you're unsure how to do this, there's instructions in your handset manual. Then just make a call, and you're ready to go. 

How to unlock your phone from another network


If you've brought your phone from another network, you may need to have your phone unlocked. If so, you will need to contact your previous network provider, quoting your phone IMEI, which can be found on the back of the phone under the battery. 

Please note that all networks will have terms and conditions for unlocking phones. 

Registering for www.tescomobile.ie

Go to www.tescomobile.ie and click on the My Tesco Mobile tab


This will bring you to the log in page, and as a new customer, you should click on "Register now"

You'll be asked for your mobile number, and some details such as name, address and mother's maiden name. When you submit these details we will text a secure password to your phone so you can complete registration, and log in. 

We suggest you change this password to something easy for you to remember once you have completed registration.


Moving your number

Your new phone/sim comes with a new 089 number, but you can keep your existing number if you prefer.

Log into My Tesco Mobile

Go to the ‘Move My Number’ section.

Follow the steps and the process takes just 10 minutes.

You will be sent a text containing a verification code to the number that you are porting to Tesco Mobile. Please check your existing sim card as this is not sent to the tesco Mobile sim card. It is sent to the number that you wish to move to the Tesco Mobile network. Enter the code contained in the text to complete the process If you would prefer, call us on 1749 and we can complete this for you.

We will need to speak to you on the number you wish to move to Tesco Mobile, so please call us on that number. Alternatively, if you contact us from another line we will call your existing number to verify your details before the port can be submitted.

Moving your number normally takes 2 hours to complete. You can continue to use your phone during this time. Please make sure that you use all your credit with your existing provider. We also advise that you copy your contacts to your new Tesco Mobile sim card as these will not automatically be transferred. You will need to ensure that you are using a Tesco Mobile phone or a phone that has been unlocked for your Tesco Mobile sim card to work.


You will need extra settings if you have just moved to Tesco Mobile, or if you have moved your sim card to another phone. 

Please click here to set up your phone. 

Using the link above, you can send settings to your phone. Enter your mobile number, choose your phone make and model, and we will send the settings to you via text. Follow the instructions provided to install the settings. 


We will send a text when the bill is ready. Payment is due 14 days after receiving this text. All Tesco Mobile customers are required to sign up to direct debit as their monthly payment method.

Select ‘My Bills’ in the menu option. Bills can be printed or saved in PDF format

Your First Bill

When you receive your first bill, you will see two lines for subscription charges. These are the monthly charge for your price plan and also a pro – rata charge. The pro rata charge covers the period between the date you activated your mobile number and your first billing date. The payment that you made online/instore will also be seen here.
