I have a brand new orange rio, and i've just inserted the sim card that has come with it, and it says 'registration unsuccessful' and then it says 'invalid sim' in the corner? this sim card and mobile are...


Hi. If your SIM is under postpaid plan, telcos usually activate the SIM within 24hours. If your SIM is prepaid, you may have to call the vendor and ask for replacement. SIM with "registration unsuccessful or rejected" is either not yet activated or expired. If you get "Invalid SIM" that means either the phone is locked to other network or the SIM is not active. Since your phone and SIM are new, it is more likely that your SIM is not yet activated. Please call your vendor if SIM is still rejected after 24hr period. Thanks.

Invalid sim


Ok, this sounds f**king stupid, but, try this
-Dial *#000#
-change the date to one in the past
-switch phone off then on
-change the date back to present
-switch phone off then on
This worked for me.... don't ask me why i even tried this
