When i put tata sim in nokia 5300 it show enter restriction code// other sim are working normly?
You can get the restriction code from the online service provider.Visit the site Unlocking4u.com .Here,you need to provide the country,network provider and IMEI number of your mobile.After they deliver the restriction code for your Nokia 5300 through mail.After unlocking it,you can use any GSM network on your mobile.
i think sim card authentication is enabled please disable it authentication is only for security reasons it is available in tools>settings>security settings>phone and sim>lock if sim changed >no confirm sim service> no if ur using tata Network try this if you have additional sim of same Company if you change the setting it require puk code u can get your puk code from customer care dont enter wrong puk code if u enter wrong puk card for three times your sim may be permanently blocked
