How do i contact my service provider ? im with o2

Your sim may have been inactive for a long period of time. Sim's don't need to be registered. try a new sim and if it still say "unregistered sim", contact your phone's service provider. good luck!

When phone completes reboot ENTER
*7465625*638*00000000*00000000#
NEXT ENTER
#7465625*638*00000000#
AND THEN *#7465625# to check the locks....all locks are inactive...these are all the locks...

I turned my phone on after 1 years of it being lost. Now it says inactive usim i know the o2 signal isn't the best in my house but help

No, its not the signal problem. It is infact ur SIM problem. U will have to call back ur network provider to resolve this. an inactive sim is always as good as dead sim. Ur SIM automatically gets inactive by ur network provider if not used (switched off mode) more then six months.

Hope this helps.
thanks

Phone keeps locking up then saying inactive sim if i turn it off then on again its ok for a while then does it again it does not matter if i am on a call or not when it happens.

i have this too, it just turns off what ever you are doing and it claims inactive sim, then goes to demo mode. i turn it on and off and on and off multiple time to fix it it may for for 5 days or 5minutes and breaks again.

From orange to O2

you could try this

By doing the reset (1st temp) you will lose all your
data ie contacts, messages, photos, videos etc etc so
back them up on your pc first.
Take out your sim card and follow the instructions below :
1st temp. put this number in the keypad
*2767*3855# let it reboot(restart)
now its ready for permanent.
Put in a sim card of a network that the phone won't
except and follow the instructions below.
( If you can't type anything with a locked sim
card inserted just take it out and do the next
step without a sim card in the phone)
Don't worry if your screen shows - - - - - - - when typing
it is supposed to do this.
Permanent.
ENTER :
*7465625*638*00000000*0000000
0#
NEXT ENTER
#7465625*638*00000000#
AND THEN *#7465625# to check the locks....all locks are
inactive...these are all the locks...
network lock - inactive
subset lock - inactive
sp lock - inactive
cp lock - inactive
sim lock - inactive
activa lock - inactive
phone lock - inactive
auto network - inactive
auto subset lock - inactive
auto sp lock - inactive
auto cp lock - inactive
auto sim lock - inactive
Enjoy !
This procedure does not change your imei number at all
