Hello my nokia 5230 has a problemes when i put in the sim card i get sim card not valid could you help me please

Hi I'm a mobile phone Tech.

If your mobile phone is on a contract with a service provider, most of the times it will be locked in with them for the duration of the contract,
So if you try to insert a sim card from a different service provider, it may say "sim card not valid'
Try to insert your original sim card and see if that works.

Otherwise if this IS your original sim card and all of a sudden this message "sim card not valid" has appeared, then the sim card has gone faulty and you need to get a new sim card from your service provider eg... Vodafone.

Hope this is helpful

Please help i wanna unlock my n73

You're probably trying to use a SIM card from a network not supported by the country you're in.
Some networks don't have a roaming agreement between two or more networks service providers to enable the users of one service provider to use their services.

Purchase a new SIM card from a popular network in that country. Ask them to unlock your phone at the same time, because it might be locked on the original network, like Orange, Vodafone, t-mobile etc...
