SIM card is also a good way to transfer contacts actually. Since the SIM card is removable, you can save the contacts in the card and then plug it into the phone you plan to use to easily move the information. Compared with other means, this method would be more convenient- you just need to take out the SIM card from the original Android and then insert it into the new phone:
Step 1. Export the Contacts to SIM Card
If you have not saved the contacts to your SIM card beforehand, you need to export them to the card first. To complete that, you can click "Contacts"> "More"> "Manage Contacts"> "Import/Export" to move your contacts to SIM card.
Step 2. Insert the Card to Another Android Phone
The next step is to pluck out your SIM card from the old phone and then insert it into the new phone. Then you need to go to "Contacts"> "More"> "Manage Contacts"> "Import/Export" again and choose the option "Import from SIM Card" in the window to move the contacts to the new device.
