Oneplus 3T Midnight Black same IMEI number for 2 sim slots

[Anonymous]

I have a Oneplus 3T in Midnight Black that has the same IMEI number for 2 sim slots. Surely this is a problem. This violates the GSM Standard. I asked Oneplus and they said this is not supposed to be like that. 

Any help?

Odd, I've not had a problem with mine, and both SIM slots have the same imei. I'll be interested in hearing the outcome of this. Perhaps this could be a wide spread issue ?

Hey guys I'm going to ask for clarification on how many IMEI numbers this handset should have. I'll update the this thread once I have an update.

Hey guys I've received a response about the dual sim IMEI number question. 

The OnePlus device reporting only one IMEI is not a fault. An IMEI is essentially a serial number that helps us identify the device on our network and systems. Each SIM slot however will have a unique IMSI number – this is what’s needed for both SIMs to function as expected. Having 1 IMEI as opposed to 2 will not alter or limit the functionality of your device compared to one which reports two separate IMEI, but with just one IMEI it does help us to limit potential fraud and abuse on the O2 network.

I hope that clears it up but if there are any further questions please let me know

Thanks for that.

Makes sence as if only one sim slot is used, and barred, someone could just swap to the other slot. Least this way, both slots are barred if lost.

No worries @Curr946! Good to have clarification on this in case anyone thinks it's a fault down the line.
