What if you still need access to some of the text messages on the sim card? I do have google of course synced to my phone so that I can access the text messages through google on my pc but I need access to 'some' of the text messages on my phone (in my phone carriers original text platform) as this is a crucial matter for my business. I'm learning the hard way with my sim card giving this same exact message. The sim card full message though, in fact went away once I was able to sync google to my new phone that I got as a replacement in the mail today. I suspect that my sim card is still quite full at this point. I can't get access to my old text messages since they did not 'come over' to my new phone (same exact model as previous though). Is the best route just to connect my phone via usb to my computer and try to find access to the texts on my sim? I still need to get to them specifically through the sim so that I can have some of them restored, but to my new phone now. I would like to delete the rest of the messages off the sim though. I'd imagine with all the coding tricks out there that there ought to be a way to access my sim via computer.... what are your recommendations?
