My blackberry is saying sos when I put a sim card in it and dont know why

It can be due to a number of reasons.....
1. sim card connectors are not clean
2. Sim Holder pins & connectors may be loose..
3. Software issue....

Seek the help of professional

switch off your blackberry, remove the back cover and battery, and remove the sim card. Replace it after about one minute and it should not read SOS anymore.
If it still reads SOS, insert your sim card into another cellphone to see if it also reads SOS in a different phone. If it does, you need to call the company you bought the sim card from.
Eg; if it's an MTN sim card, call MTN; if it's Vodacom, call Vodacom etc.

you pobbably dont have the sim caard in right switch it off then put the sim card in a different way maybe try it upside down and turn it on again it should say on the sim card how it goes in anyways

it may be due to network lock, contact service provider if it locked , you can get unlock codes here http://www.theunlockspot.com/blackberry-9800-torch/rs10wp9/
you need to specify the country and network provider

SIM card is either bad or not authorized to work on that carrier network. Make sure the SIM card is installed correctly.

Replace the SIM Card with your service provider

1. (easyer way) When I got my Blackberry, I had to put it in a couple of times for it to work.

2. Buy a new sim card.
If this does not work, then check to see if it is unlocked.

you are not getting the network signals.
