Like so many others I have an old (dumb) phone model, Samsung SGH-C300, which I am having trouble getting working with the new SIM sent by Virgin as part of their forced upgrade. On installing the new SIM I simply get "Wrong card" on the screen. Does anyone know how to overcome this? My accompanying Virgin letter included 2 unlock codes. Can for example various *#7465625..... commands be used, or are there any other suggestions?
Thank you for your reply. I do not know whether or not the unlock codes Virgin sent work or not as I am unable to enter them. As I tried to explain in my post, on inserting the new SIM I simply get a screen saying "wrong card" and I am unable to proceed further. (My existing SIM works fine).
I would appreciate please specifically to know either how to proceed past this "Wrong Card" screen which the new SIM produces and if necessary be able to enter these codes, or perhaps some other alternative solution to getting the new SIM to work on the phone.
Thanks very much for your detailed reply. Much appreciated.
On starting the phone without a SIM I get a screen saying "Insert SIM card". When I now type in * # 7 4 6 5 6 2 5 # to see what is locked, immediately on entering the second # I get a pop-up screen saying "SOS call only". How do I proceed please?
Thank you again. In case I manage by some miracle to eventually get beyond this initial screen, can you tell me something about the 2 unlock codes Virgin sent me in their letter. They did not identify what they were, but simply referred to them as code 1 and code 2 to be entered in that order. Which unlock codes exactly are each of these in terms of the types you listed?
