YOU NEED TO REPAIR IT.. BUT ITS DIFFICULT TO DO YOUR SELF. I REPAIR PHONES BUT I PREFER TO SEND THEM TO GOLDENLEPRICON. COM THEY HAVE A FAST TURN AROUND AND THEY CHARGE VERY CHEAP.

sony k550i showing inserte tarjeta sim even if sim is correcectly inserted.what to do.

Here's what you have to do.

Maybe your sim card is not well fitted on your sim card port. If you thinks it is well firtted, based from my experience, just insert your sim card as usual to the sim card port and then do that 5 times. (rubbing slowly). and then try to power it on. Just try it. Hope it will work for you..

hi ive had exactly the same problem as you and when i took my phone back to 02 they said it was water damaged, i have since sent it off for a repair with another private company and they have said they are 95% sure its a software fault due to the way my screen was turning black and then saying insert sim, but i shall let you know when i get it back if it has fixed it or it could be something like the sim card reader but please dont be fobbed off saying its water damage they shall just drop a bit off water on the water tab and say its beyond economical repair

a SE pc suite could help..

u have soultion sonyeri w880i insert sim card

your sim card broken. go to your operator office ask for sim card change.

i think the sim validity period has been expired ...
i mean if you didnt recharge for 90 days the sim validity will be getting expired automatically... this is made by the network operator in standard for all sim cards ....
if it is not true then try inserting in other handset & have a try ...
if you face same problem then really the sim validity has been expired ...
take a new sim....

i you should try a software update, you can get this from www.sonyericsson.com/support. hope this helps
