Transferring your contacts.

There are lots of different ways to transfer your contacts. However you
choose to do it, the first thing we suggest is to copy your contacts off
your old phone and onto your new SIM or your computer. For a step-by-step
guide, select your phone on our device support page and scroll down to
the Getting Started section.

 

If you want to text your contacts to let them know your new number, remember that if you send a text to a list of people that includes an email address, all the texts will be counted as picture messages and they won’t be covered in any free text allowances you have.

If you’re using a phone that’s new to Three, you may need to get new
settings for the internet and picture messaging. And don’t forget, if you’re
on a BlackBerry® you’ll need our Add BlackBerry® Add-on in order to use
BBM™, email and the internet.
