who i can unlock my iphone 4 with telenor sweden carrier

Contact your carrier. Only the carrier to which the iPhone is locked can authorise its unlocking, however, I don't believe Telenor support authorised unlocking so you maybe out of luck.

i contact telinor they unlock iphone 4 in 350kr bt they need payment method should be complated with swedish credit card no other option to unlock iphone 4

i had succes unlocked my iphone 4, very happy... 😁
