fixed number dialing suddenly activated
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?
