Sooooo I'm a regular visitor to wonderful Peru and usually buy a new sim card on an annual basis. This year however I've stayed longer (5 months) and I've continued to use the same SIM that was registered by a Peruvian friend of mine who lives in Iquitos. I'm now in Lima and got a sms saying my phone IMEI number is not on the white list and I need to go to the provider. So I visit Claro and of course they tell me they can't do anything without my Iquitos friend being there. This of course is not practical so I try to think of a solution to get myself added to the white list. Another friend of mine in Lima kindly offered to register a Bitel sim for me which we did yesterday one day before the block is supposed to happen. I thought this meant automatically it would add me to the white list. Now cut to today. At noon my Bitel sim stops working. So I go to Osiptel who once again tell me my Iquitos friend needs to be there to fix the issue. But THEN I put the claro sim in and it works! Can anyone explain why the IMEI block seems to only be on one sim?
