Sony Xperia M no signal - SIM works in other phones

[Braddingo]

Hello.

I have recently had problems with my Sony Xperia M phone.

I recently dropped the phone and the screen had cracked and so i issued for a fix at a local shop and so i had to remove my sim card, sd card etc. As the phone returned to me i have not been able to have a signal however i get a very slight signal 5 minutes away from my home which makes no sense as i used to get full bar signal strength in my home before i took it in to get fixed.

I have searched for mobile network operators at home and it will not pick up any at all.

I have tried a factory reset; this did not work.

I have tried the Sony 'Update Service' and have also updated my phone to the latest version but nothing is working at all which is leaving me somewhat confused.

Heres what it says when i go to 'about phone':

Network: no service

Signal strength: 0dBm 99asu

Mobile network type: unknown

Service state: out of service

Roaming: not roaming

Mobile network state: disconnected

My phone number: unknown

IMEI: removed by alexdon - no private info on the forum

IMEI SV: 

Also i have tried my sim card in my friends and parents phones and it works perfectly just like it used to. Also have tried their sim cards in my phone and they could not get a signal at all (the people were on my network also).

I'd appreciate help as i'm getting very frustrated.

Thanks.

I was wondering if you managed to overcome this and what you did? Would really appreciate any help you can offer. 

Thanks so much.

Hi all,

Try this.

1) Go to setting.

2) In wireless and network section, select "More..."

3) Select "mobile network"

4) In that, choose "Preferred network mode"

5) Select "GSM Only" option.

And It's done.
