    yep i've got the same problem. The telstra shop are trying to redo all the software on it, but the manufacturer won't stand by the phone unless it happens in front of an operator in the shop which of course i can't make that happen. What good is the 30 day warranty? So frustrated!

    I have the same problem with my new SE w760. I just purchased 2 of them a little over a month ago form an AT&T corporate store. The phone just started displaying "INACTIVE SIM" and then vibrating and turning itself off randomly. I just tried your duplication idle but it didn't work on my phone. I plan to bring it back to the AT&T store to see if they can help but not sure I will end up a satisfied customer after reading these posts and many more on other sites. Like you said - if it is a design flaw, nothing much they can do - especailly if I can't duplicate this in front of them.

This is a known design flaw with the w760i - it occurs when the phone requests info from the SIM (building contact list etc.) and the SIM connection is lost. This would happen on any phone but the w760i has a shock protection design issue whereby closing the slide quickly causes the SIM to disconnect. You should be able to replicate the issue by turning the phone on and slamming the slider shut as soon as the phone shows your network name. Leave the phone on for a bit and you will feel the phone buzz and 'Inactive SIM' will display, the phone will then reboot.

The problem is not the service provider, its the phones firmware, re-flash it. use a program called A2 Uploader. it takes about 10 mins to re-flash your phone with new firmware.

Hello and Welcome to FixYa!
Inactive SIM message may arise due to more than one issues. First things first check the hardware of your phone, to do this Put out the SIM card and check what happens. If it shows insert SIM card, its normal. If it shows the same inactive message then hardware malfunctioning.
Ok if the hardware is ok, then its simple. Inactive SIM means that your SIM card is not being able to register your Network carrier. The Phone with a red-line means SIM card registration failed. Although the signal radar works. This may be due to 2 issue; either there is a issue at the Service provider End, to check this call the service providers from other cell or land-line and check the status of your connection against this SIM Card No. If they say everything is ok. Then Its confirmed that your Phone is Network locked (Can only be used for one specific network) In this case coordinate with the seller.
I hope you will have a clearer picture now.

If you have any Confusion, questions or issues regarding your problem do tell me.

Can't send or receive text messages


The problem is not on the phone setting but on the sim card itself. Remove the battery and the sim and let it sit for 5 minutes. After that, insert sim and battery then try sending a text message.
To verify, insert your sim to another phone and use a different sim in your phone.
