Network connectivity

[Yvonne1]

Hello, my name is Yvonne from Kenya and I'm a die-hard Sony user back from when it used to be known as sony ericsson. I recently got an Xperia Z as a gift but have been unable to connect to local network operator. The phone detects a sim has been inserted but then i get a big red X with 'No service' alert. This despite having replaced the micro sim twice (both worked well with my other phone) and also resetting phone to factory settings. Does this really require a visit to the Sony service centre here? I'm back to using my old samsung but please help as I'm really itching to put my swanky new device to good use!

sorry if I'm stating the obvious here but make sure you are installing the sim the correct way

are you saying the phone can see the sim but won't connect - is your phone from a specific carrier and locked to their network or did you get it unlocked, you can check this *#7465625#

Do check what Geoff has advised and if all checks out please attempt this:

To repair the phone software
1.     Install PC Companion on a Windows PC from Support
2.     Turn on the phone, and connect it to the PC using a USB cable.
3.     In PC Companion, under Support Zone and click Start.
4.     Under Phone Software Update, click Start.
5.     Click repair phone.
6.     Follow the on-screen instructions.

before you go thru all that, you need to make sure that the phone support your network baseband or the sim card. for example, if the phone is the 4G version, your sim card and service plan need to support 4G as well.

you might want to check from the person who gave you the phone. the other way of finding out is to bring your phone to your service provider and ask them to check if the phone is compatible.

Yes sim is inserted correctly and detected by phone but won’t connect.  The unlocking no. code
gives an MMI error when dialed from Xperia Z but is accepted on my old Samsung GT-E200. Interestingly invalid MMI code error also received when dialed on the Samsung Galaxy.

I have repaired phone software only bit I couldn’t do was remove battery as I think the Z model’s is inbuilt. My PC reports that this phone is now upto date on software.

I’m still unable to connect to local network, Bharti Airtel.

  🙂 too late, I've been through all that & nothing working still. 

I am now booked to visit Xperia Z authorized distributor tomorrow to establish whether my phone is compatible.

Thank you for all your responses, the support is important.

I believe you can find the network carrier lock status by going into the sevice menu  *#*#7378423#*#*

The Sony service centre here in Kenya are working to solve this problem now. Fingers crossed!
