IMEI Blacklist Checker

First of all, what is an IMEI? And what is an IMEI Blacklist? An IMEI is basically the unique number that represents your phone. It has 14 to 15 numbers and you can quickly know your phone unique IMEI number by pressing *#06# on your phone keypad. An IMEI that is blacklisted is basically a phone that was reported lost or stolen. So if your phone IMEI number was blacklisted, this also means that your phone is blacklisted. A network operator who received the report by its previous owner would put the IMEI number of the phone to a blacklisted database. This IMEI is also called as bad IMEI. So if your phone have a bad IMEI, it is possible that the phone you are currently using might be stolen or was reported lost by its previous owner.


If the phone was reported stolen, the phone will be unusable in most carrier networks even if the SIM card is changed. So, how do you avoid this from happening? First of all, you can always avoid this by not buying stolen phones or not buying a phone from untrustworthy sources. This is because once you bought the phone from unauthorized source, it would be difficult to return your phone once you know that the phone has a bad IMEI. But, sometimes you could not avoid this and you might be duped by this people and thinking that your phone is a brand new one. The best way is to check the IMEI of the phone quickly and to determine whether it is good or not. Some network operator such as T-Mobile allows you to check the phone’s IMEI at their website. Just go their website and you can simply type the IMEI number of your phone to check whether it is blacklisted or not. There are also several websites that are offering to check the IMEI is blacklisted or not based on available database from the network carriers. So, make sure your phone does not have a blacklist IMEI before purchase. This would save yourself a lot of headache.

Can We Track Cell Phones on Airplanes?

As the search still continues for the missing Malaysia Airlines MH370 plane, the exact location of the plane is still shrouded in mystery. There are some family who try to contact their loved ones who boarded the plane by cellphone. Some said that they heard the phones ringing but there is no answer. However, as explained some of the experts, a ringing does not indicate that the phone necessarily can be contactable and traceable. So, the question that we want to raise here is that can we actually track the plane by locating their phones through the GPS technology. Based on some reports, the family of the loved ones actually requested China Mobile, China biggest telecom operator to track the phones of the passenger of the missing Malaysia Airlines.


However, based on official reports, they could not detect their phones. Please note that the technology often used in tracking phones are based on GPS technology. Even most of the apps in the market that can used to track phones utilized this technology. So, with this technology it brings the limitation in which it could not be detected once it is above 10,000 meter in the air or deep down in the ocean. And also, the telecom operators can only track the phones only if the phones are connected to their network. So, usually there is no coverage above 10,000 meters in the air. But how about the Wi-Fi provided by the plane? Can it be used to track the phones if the phones are connected to the wireless internet connection? This is possible as long as the plane did not crashed or in the deep ocean. But, normally long haul flight such as MH370 does not have Wi-Fi services onboard. This is due to the reason that the Wi-Fi services onboard still depended heavily on cellular towers on the ground. So, when the planes cross the ocean, there is no connection to the internet as there is no cell towers to be connected. However, all prayers to missing passengers of MH370 and hope they will be found safe and sound.
