Question about sim free phones...?

Hi liam just purchase the phone pop your sim card in the new phone & it will work ok with no problems just explain to the staff in the shop that you want the phone to work on orange ! but what you will need to do is either contact orange or go on the website & get the settings for the internet & also the settings for mms (picture messaging) ! as in saying that though when i bought my sim free phone from the carphone warehouse & put my sim card in i had a couple of texts from my network provider for the settings so you may well find that orange may do the same ... hope this helps sly
