Hi PHayter, thanks for the message and I am sorry to hear that you are having issues with the sim. I am sorry to hear that you are getting the message of invalid sim. Can you confirm if thed phone which you purchased was unlocked or is it locked to a particular network, has the sim card been activated? Can you try the sim in another phone to see if you are getting the same issue? Chris
Thanks for popping back and re-confirming the checks that you have already done; I am sorry about the confusion and any delay caused. Your new SIM may not have been activated as yet - we can certainly check this out for you and see if we can assist you further.
