How to Make Phone Blacklisted using IMEI Number ?

Every cellular phone, GSM device or modem with an integral cellphone modem has a unique 15 digit IMEI quantity. Predicated on this true number, some information can be checked by you about these devices, example: brand or model.

What is a blacklisted phone?

A blacklisted phone is a phone which has been barred/blocked by the operating network for reasons such as it being reported lost, stolen or the original owner has not kept up the payment of their contract bill.

There are many signs that the phone has been barred/blocked by the UK networks – these include:

  1. No signal when a sim card is inserted
  2. “Invalid Sim” is displayed on the phone
  3. “Inactive Sim” is displayed on the phone
  4. “Sim Registration Failed” is displayed on the phone
  5. “CALL FAILED” is displayed when dialling out
  6. A “BEEP-BEEP” tone is heard followed by the call ending when dialling out
  7. Your friends try to ring you but cannot get you even though your phone is on!

It’s also very common for people to abuse their phone insurance by selling their phone privately, and then later on reporting it as stolen. They then get a brand new replacement phone, leaving the poor person who paid good money for their old one to wonder why the phone is having problems with reception etc.


How can I check to see if my phone is blacklisted?

If your phone is experiencing one or more of the above problems or you are simply thinking about buying a certain phone from a shop, market or local paper and want to check it’s authenticity then you can use IMEI checker tool using the 15 digit phone IMEI number you provide us! The IMEI number is a 15 digit set of numbers found normally under the battery on a label and starts with 44 or 35. You can also check IMEI by powering on the phone and entering *#06# and the 15 digit IMEI will be displayed on the screen instantly – this is also a good way to check if the displayed IMEI is the same as the IMEI on the label behind battery!

Whilst we will endeavour to provide you with the latest information relating to the information you submit to us, it can sometimes take a while for the network systems to update, so we cannot guarantee the information we provide is 100% accurate with regards to blacklisting!

But in over 90% of occasions we will provide you with information regarding make/model of handset just from the IMEI number, and even details of where the phone originated from! This can be of use in determining if the phone has had its IMEI number changed – This act is illegal in the UK and carries up to 5 years in prison for anyone caught carrying out this act on a phone!
