Re: k750i

Consult Virgin to get the proper settings for their network. Your phone is still carrying the old settings from your old provider, thats why it giving you this error. I believe Virgin has these settings available on their homepage, otherwise give them a call and let the supporter help you through the setup process.

Why phone will not send a text

You must have a SIM card inserted to make calls and send SMS. Check if you have the SIM card installed. If not, talk to your service provider.

Ive got a sony ericsson k750i and cant get on the internet

Mobile internet settings are very much service provider dependent.

Sony Ericsson maintains a support service that keeps track of the operator internet configurations and, when you enter your mobile phone number, the webpage sends an SMS to your phone which sets the your default internet settings of your service provider. This might not be appropriate for everyone (e.g. I am using a corporate subscription in which we use non-default internet access point name).

On the k750i the default internet profile can be downloaded from the mobile menu itself.
This information comes from the sony ericsson support page:
  1. From standby screen, select 'Main menu' --> Control panel --> Connections.
  2. Open Internet wizard, and tap 'Accept' to download the settings.
Note: The first time you start your phone or insert a new SIM card, the Settings download is triggered from the start-up wizard.

I cannot send nor receive calls, nor send and receive text messages as of yesterday, April 18, 2011... I am currently using a postpaid SIM... thanks

there are several factors why you are unable to send and receive messages and make outgoing calls and receive incoming calls.
network issue: are you the only one experiencing the problem? try to check with someone who is on the same location and is using the same network as you if he or she is experiencing the same problem as you. if yes, then it may be a problem with your network.
make sure that you have good signal and contact your service provider too and ask them if they have an ongoing maintenance in the area and ask if the sms and calls services are activated on your account
phone issue: if you have a good signal and still can't send, receive text messages, do and receive incoming, outgoing calls, try to do these: call the service provider and ask for the default network pin, then go to the settings of your phone, call settings, call barring, deactivate all barring
try inserting your sim card to another phone and try to send an sms
turn off your phone, remove battery and sim card and then wait for a few seconds, then put back the sim and battery and turn on the phone then try to send an sms

My lg cookie won't send messages

you need to check that the SMS centre number is stored in your phones SMS settings (you can get different mobile provider service number by searching the net) If you cant enter it, then get a different SIM card, the same provider as yours, put it in your cookie and send a message. Then put your SIm back in, and you should be able to send messages.

My sony erricson w580i wont send texts

I had the same issue. First, you have to identify if the problem is on the network side or on your handset. Call up the network provider's customer care service and find out if the text settings on your phone are apt. By settings i mean the service center number, 'circuit switched' 'packet switched' etc. If the settings are apt, and if you have enough text credit, the problem is with your mobile phone. Now, remove your sim card if its GSM and put it into another handset while you put another sim card in yours. Now, send text messages from each handset to the other, This will work fine. Once this is done, you can swap the sim cards again and the texts should work fine now. Best, k6

I am unable to send pictures from my motorola razr v3 black,text messages are o.k. I am using my virgin sim card from my old sony. Does my v3 have to be registered with virgin to send pictures? Please any...

Hi , The settings for this function are stored on the phone via txt message from your service provider (virgin).When you use your sim in a different phone all you do is request settings to be resent and install from the options that come with the message , check the phones/sim stored numbers for virgin to txt "get settings" , or check online for the number to request

Error message when texting on Ericsson K750i mobile

tmuncey hello,

Sometimes because of a phone bug or a SIM error, the "Service Centre" for SMS messages is changed.
Please call your cellular Service Provider, and ask for their SMS Service Centre settings.
Then, go to Messages > Settings > Text Message > Service Centre.
Make sure the number you were given by the Service Provider matches the one written there.
If not, please changed to the one given to you by the Service Provider.

Se k800i cant recieve sms

I think the problem is your phone has some settings that disabled your SMS functions so I suggest you to try and put your SIM card in another phone and try sendng SMS. If it works, try Reset Settings from the K800i. If it doesn't work, try changing a SIM card from your service provider.
