Text messages often need to be saved for business and personal reasons, so when you get a new phone, you may want to transfer messages with sensitive information. This can be done through several methods. Different phones are better suited for particular methods of transferring.
SIM card transfer
Turn on your old mobile with its original SIM still in it. Navigate to the text message folder and select the options menu. This option may not be available in all mobile phones.
Review the listed items within the options folder. To determine if you are able to lock, or save, messages directly on the SIM card, see if you have a "Save" or "Lock to SIM" option. If the phone is capable of performing this action, it will be clearly listed in the options folder. Some mobile phones require you to select a specific message before going to the options menu. With this type of phone, to save messages to the SIM, you will select "Lock" from the options menu after selecting a message.
Select the "Save" or "Lock" item within the options menu. This will save your text messages, or a single text message, to your SIM card.
Remove the SIM card from your old cell phone and put it in your new phone. Navigate to the text message folder to ensure that the saved messages have been transferred.
Turn on the old and new phones. This form of transferring text messages will only work if you are using a new SIM card with the new phone and your old phone is still activated.
Navigate to the text message folder in your old mobile phone. Select the messages and send them to your new mobile phone by copying and pasting. You can also select the "Forward" option within the messaging options menu if available, and send the message directly to your new phone. You will be instantly notified if the transfer was a success by receiving the text message on the new phone.
Repeat this process until all of the text messages have been sent and received.
If you are unsure about being able to save messages directly onto your SIM card, review the owner's manual for your old phone.
