SIM CARD REGISTRATION failed, N70
Factory resetting the phone will do absolutely nothing with this problem
There are 3 causes of Sim Card Registration Failed, when you first turn on the phone, the sim card attempts to connect to the network if it can not do this it gives a message like Sim Card Registration failed.
1, The sim card is turned off (is it Orange) if you have had the sim card for a while and it hasnt been used they will turn it off, you need to contact them from another phone to get it turned on or get a new sim card.
2, The phone has a hardware reception problem, when it attempts to register itself with the network it can not... There is a reception problem and it requires repairs, this isnt really an easy diy job on this handset.
3, The phone is blocked, i.e reported lost or stolen. Some networks when a phone is reported will allow it to get reception but will not let it make calls, however other networks will not give it reception at all and hence you get a Sim Card Registration failed message.
I hope this helps, these are the causes of the message.
