The IMEI number is tied to the actual handset, not the SIM. If you have a handset and you replace one SIM with another, your phone number (and SIM number) will change, but your IMEI number will not change.



Therefore it's erroneous to say that just because Lumumba's IMEI number remained the same, his phone number (and SIM number) remained the same. He could easily have been using the same handset (hence same IMEI) but changed the SIM card (hence new phone number). Of course it could be the case that his entire setup - handset and SIM - remained constant, but one cannot automatically infer that from the fact that only his IMEI remained constant.



(In a properly-functioning network/operator market, phones (by way of their IMEI) are meant to only work with certain SIMs, in order to prevent theft and misuse. But, particularly in countries with thriving grey/black markets such as Italy, it's easy to get a handset "unlocked" such that it can be used with any SIM.)
