Question about Sony Ericsson Z550i Cellular Phone

1 Answer

Network problems Hi everyone, My sister's Z550i has a problem with network connection. It does not "hook up" to the operator's network, which is the biggest/best operator where we live. She cannot text, call or anything that has to do with network connection. Her phone began to act weird a couple of days ago when we were at the movies, she had it turned off. Then when she turned it on again, after the movie, it had no network signal and it has been like this since. (We were in town... we live in town, so I doubt that it has to do with the operator since we checked if it was her sim-card going weird, but it wasn't - checked it on my phone, and the sim worked). After the movies, her phone said "Inactive SIM" when it worked perfectly on my phone (SE Z610i). Now it tells the operator and all on the monitor, but it still fails to connect to the network. This has never happened before on her phone. Thank you :3

    She updates the software on regular basis so I doubt it has anything to do with that.



    Just did the master reset, it doesn't work.



    Thanks anyways.

Hi,

This could be a software failure. A master reset or software update could solve this problem,.

When i insert the sim in my mobile z550i he show the phone lock code i don't know what the code how to troubleshoot this problem please help me


Hi,

NETWORK UNLOCK CODE:
To unlock your mobile you need to get network unlock code(NUC) from current service provider via phone or go to service provider office.

While you get the Network unlock code ,the service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only.If they are satisfied with your answers they will provide with the network unlock code.

RESTRICTION CODE:

To get restriction code you have to call your previous service provider. This code is provided to prevent in case of theft taken place the other person cannot use your phone in other networks.

While you get the restriction code ,the previous service provider customer care officer will ask for your personal details to check whether the mobile belongs to you only.If they are satisfied with your answers they will provide with the restriction code.

Thanx

Initially check the mobile with other network operator sim card to ensure problem occurs in that also .Normally this problem is due to the Network and other IC in the mobile.Better contact a good service person to solve the problem

No access to netwotk in sony ericsson Z550i


Hi Ravindra, the first thing I would suggest is trying your SIM card in a different phone. This will tell us if the problem is with your phone or the network.

If the problem is with your phone, I have fixed similar problems on Sony phones by flashing the firmware. It sounds scary, but Sony makes it really easy to do. You will need a USB cable to hook your phone up to your computer, then go to http://www.sonyericsson.com/cws/support/softwaredownloads/detailed/updateservice?lc=en&cc=us and download the update software. The software does the rest, it's easy as pie and has fixed many problems I've had with Sony phones.

My sony-ericsson z550i display says no network and no coverage area.


go to settings-->phone-->network, try selecting the manual network option, if its able to find a network, you can request register on it, once back to main screen select "automatic" in network so you don't have to search your provider network everytime you loose signals.
