My nokia 1800 only works with vodafone, not any other sim. So, what sholud i do?

Your Nokia 1800 is locked to its Network, that's why it shows "Sim not valid". In order to use other carriers, you need to unlock your phone. You can do this with Network unlock code. You'll be able to get this code from your service provider. If not you can get it from online sites. To have a clear picture on how to unlock your phone using the code, visit , this site gives you free instructions on how to unlock your cell phone.

Solution of 1600 sim not valid?

If your mobile says "SIM not valid" then it must be a network problem. If your mobile is locked to a network you can only use that SIM. IF you need to use other network SIM you have to get a unlock code from your service provider. This is the reason why your mobile showed that message. Sites online also provide unlock codes. I usually unlock at which gives good solution.
