Living in Indonesia, I bought an iPhone 4 from an official retailer, incl a microSIM card. The iPhoe is (officially and legally) unlocked, and when going to holidays I usually buy local prepaid cards and insert them without problems. Being abroad, I lost my original Indonesian SIM card, and after coming back home, I went to my retail store and got a new one (with the same number). But now, every time I insert the new card, the message "fixed number dialing is activated" appears on the screen, and the iPhone shows no connectivity to any network or provider. Just out of curiosity, I put the new card into another phone (Sony Ericson) - and it worked! I put another SIMcard into my iPhone - it worked. So, what is the problem? And what is the solution?
Contact your carrier & get a new sim card.
Fixed Dialing Number (FDN) is a service mode of a GSM phone's SIM card. Numbers are added to the FDN list, and when activated, FDN restricts outgoing calls to only those numbers listed, or to numbers with certain prefixes. Not all SIM cards support this feature, a PIN must be entered beforehand, which is unique to each SIM card and provided by the network operator. The PIN to enable this is separate from the PIN to lock or unlock the SIM. Many parents use this to restrict calling on phones given to children.
Sounds logical and convincing. Thanks. I'll go and try to explain to them the problem ... not sure, the girls in the store will get the point ...
Well, fact is your carrier does this through the sim. Just get a new sim.
Thanks, problem solved ... although: the tekkies in the retail store did not believe that we need a new card. For more than 2 hours they tried to unlock the card when inserted in another phone, what actually was possible. But each time they put the unlocked card into another phone (e.g. my iPhone), it locked itself up again ... But it is their money they are burning, isnt it?
