How Can I Transfer My Phone Numbers To A New Phone?

Save all your phone numbers of the phone to your SIM card. (Save them onto the sim card by Moving them. Do not copy them otherwise you will not know which ones you have transferred).

Put the SIM card in your new phone, and go to contacts. Go to settings. Go to 'Copy sim to phone'.
Once that is done, delete the number on the sim. (they will all be on your phone).

Repeat the steps, if you had a long list of contacts on your old phone, and weren't able to transfer all.

Second option is, send them via Bluetooth, one at a time. You need to go to each contact, and click on 'send business card via bluetooth'.
