Frequently Asked Questions
What does blacklist mean?
It means the IMEI code of a device was reported lost, stolen, or with unpaid bills or installments. This is an additional restriction set by the network carrier.
It is also known as having the phone blacklisted or reported.
When a device is blacklisted, some of its features will not work, and it's easy to identify if the IMEI is blacklisted, as the phone will not connect to the network and won't be able to make or receive phone calls. Sometimes, you might be able to send SMS or use mobile data, but you cannot make phone calls.
Usually, when an IMEI is reported, the phone displays one of these messages: "error MM6," "connection error," "No Service," "SOS/emergency calls only."
Is it useful to run an IMEI Blacklist Check?
With the IMEI Blacklist Check service by doctorSIM, you can find out if a phone is reported or not, also known as "clean."
We recommend this phone check for several reasons:
- To buy a second-hand phone with a guarantee that the IMEI is clean. Ask the vendor for the IMEI info and tell them to give you the phone's IMEI so that you could check it yourself
- To sell your phone second-hand and ensure a safe transaction
- To network unlock your device with all guarantees
Can the blacklist be removed?
Yes, it can be removed, as long as the phone's legal owner contacts the original network carrier that reported the phone.
A blacklisted IMEI can only be removed by the network carrier; no other company or entity is entitled to do so.
In order to remove the blacklist, the legal owner of the phone has to provide proof that the initial situation that caused the phone to be blacklisted has been resolved.
