It wont connect to the network so i can't make calls it just shows the red sos sign.

You are losing signal and cannot connect to the network. Signal strength may be affected by weather or other conditions. You might find the X disappears when you change location, for example. So, the problem may be in the environment, in the network, or in the SIM card. If it is a bad SIM card, such has to be replaced. If it is a network problem, you would have to contact your service provider. And you can't do much about the weather other than try the phone is a different location. Generally, a red X means a function is not available and you have to go into setup to enable the function. But in this case, you are having network connection problems where the phone cannot detect the signal.

I solved this issue for one of my customers . Here were our steps:
Options > Network & Connections > Mobile Network > Network Technology should be sent to 1xEV.
As soon as we switched it back the SOS disappeared. SMS started incoming immediately and voice tests were successful!

Hi is your blackberry mobile not accepting your 3 network sim in it this might happen if your phone is locked to some other network provider then it wont accept 3 network sim until you unlock it ..SOS on the screen signifies that the phone will allow only emergency calls ...You can easily unlock your phone using online providers like UnBBLock.com here they are rendering network unlock code for all blackberry mobile models at reliable cost ...You first check that whether the code is available for your mobile model ,country and network provider .If yes then pay for it and unlock your phone then freely use it with any GSM sim ...

The SOS calls only happens under specific situations on mobile phones. If you haven't paid your bill or are out of minutes on your plan, then the message will always show up. If you use pre-paid cell minutes, check your balance.

Similarly, if your phone isn't within range of a cellular tower for your network but does have signal from other networks, the phone will allow emergency calls to go on the other network. Talk to your provider about the coverage area and check if you were in a covered area.

A damaged SIM card could also give the problem. This is due to looking like a "not on plan" phone. Talk to your provider about the SIM card if this could be the problem.

I hope this helps.
