Sony Ericsson K750i Cellular Phone - Page 6 - Answered Questions & Fixed issues

Activate blutooth from the main meny/setup (tool symbol), then navigate to the far left meny tab (communication) and turn ON your bluetooth radio, and enable the "visible" status for your phone. Then turn on your handsfree device, and the phone should either find your hands free or vice versa. Many handsfree devices will ask you to enter a pin code once it has connected to the phone to allow connection, so be sure to have the code ready.

Hi. Had the same problem earlier. (I assume you use an original or compatible head set cable.) It turned out to be caused by corrosion/dirt on the contacts on the bottom on the phone. You should inspect it and you can use a small sharp object and gently scrape/rub the contact points until any dirt or miscoloration is removed. In the end these contacts will need to be replaced as they suffer from wear and tear as well as corrosion. New contacts are available as spare parts from many internet sources. If you need help to open the phone and change contacts, please add a separate request.

Try this freeware which is Sony Ericsson specific. If you donate to the developers ypu will get access to bonus features too. Higly recommended.

do all the contact pins on the phone reach the simcard?
you can try to pull them up a little bit carefully.

Hi the problem you are having is with your message center number this is a common problem and usually happens after you have changed your sim card to another network all you need to do to solve this problem is call your service provider and tell them the make and model of phone you have then ask them for the correct message center number.
they wont charge for this and they will tell you how to set it up, you will also need to ask them to send you the latest wap and mms settings so you can use the net and send and receive picture messages. they wont charge for this either and they will send you these settings via txt message and this will then update your phone to the latest settings.

let me know if you need further assistance ok

As you have not specified in particular what is the unlock code required for you, i am giving the ways to unlock all the codes

NETWORK UNLOCK CODE:

You can unlock it by flashing your mobile if your mobile is a CDMA mobile...
The procedure for flashing your mobile is in the link below
http://hubpages.com/hub/How-to-Flash-your-cell-phone
It has an video explanation.

If your mobile is not an CDMA mobile , you can get the network unlock code(NUC) by just contacting the current network provider customer care department.It is free of cost.

The restriction code can be got from your old service provider..This restriction code is kept to prevent someone who stole the mobile from using it with another provider...

They will have a security check done with your date of birth etc..to verify whether you are the exact owner of the phone..

After that they will provide you the restriction code to unlock it and use it with another service provider..

It is all free of cost do not pay anyone for this seeing some advertisement over internet . That is all fake ads.

The above procedure works and you can verify that by seeing the rating of an happy customer here..

click the link to reach download page
click the link DIRECT DOWNLOAD
but these only support xp/vista..
there are no other pc suite for win 2000..
no way you should have win XP/vista

You can download all the required software from this website. OR click here for a direct download of PC suite.

Download PC suite to your hard drive, remove any connected mobile, install the software; restart PC and then connect the mobile.

PC suite allows you to make back-ups, synchronize content, update time and date settings and enables it to be used as a modem (settings required from the service provider first).

SE Update service allows you to download latest updates to your phone. Its optional but recommended if you are having a problem.

Sorry, Google Maps does not support the SE K750i.

if you sure that flashing is all that being done to your k750i, flash it again but make sure that you will use the compatible flash file for your k750i.

DID you get your GPRS setting from your Network provider

a phone repair shop could fix this for a small fee i dont think there is anything you can really do apart from that

reprogram the phone,that's a software problem
