My j1o5i after starting shows only demo and insert sim message.even after inserting sim it not recognizing it.it not working forther.please provide a solution

Do you get this error message?As far as I know there are three chances to get this error..one is the sim may not have been inserted properly...try to insert it in the correct position.There may be an error with the sim try to insert other sim cards into the phone.Another chance to get this error is when you try to insert a sim other than the locked network.If your mobile is locked with a particular network then it will work with only that and will not be able to recognize/accept other networks.Inorder to unlock your phone you can either approach the network provider or third party unlocking vendor like Mobile-unlocker.com and remove the network lock.
Even after all this the problem persist it may be due to some hardware problem try to get in touch with the nearby mobile store.

it may be due to network lock, contact service provider if it locked , you can get unlock codes here http://www.mobile-unlocker.com/sony-ericsson/rs2wp8/
you need to specify the country and network provider

demo shows about how the phone will use and if insert a sim it will start work properly

If you are trying to use an old sim-card from another phone you may find that it won't recognize it.

The older sim cards just aren't up to the job the newer handsets require so now we have more powerful and higher voltage sim-cards.

Try a sim card from a friend with a new handset and see if that works in your phone.

You may have to go get a new sim.

hi, have you tried inserting another sim card? try inserting another one and if you still get the same message it means the the memory space of the phone might be faulty...if after inserting another sim and it worked properly, it means that the sim card signal is week..it means you have to contact your service provider.

my k550i says on screen please insert sim or watch demo first done both an message is still on screen help??

The sim card holder has a tiny slide mechanism. After inserting the sim card and pressing it against the body of the phone, place your finger over the card and slide it gently forward. The tiny plastic part that holds the card will snap it into place. Hard to explain, but it will work.

1. Is there a SIM card in the phone? Is the SIM card from the same carrier/provider you got the phone from? Was the phone purchased as part of a plan or separately?

2. I see the not charging message a lot with my v551 that I had. I usually adjusted the inserted connector (after insertion) and 85% of the time, the phone recognized the power coming through.

If this fails, then try another power adapter. If after trying a new power adapter does not work, then the pins on the phone has sustained some damage.

Hope this helps :) Kindly leave a rating. Thanks..
