Oneplus 2 IMEI not recognised

[Anonymous]

Hi,

I recently purchased a Oneplus 2, and put my seperate o2 sim in. I've noticed that I don't get a 4g connection. I have been on the o2 website, trying to upgrade to 4g. Everything is fine in the setup, until they ask me to give me the IMEI number. When I give it, they claim that they cannot recognise the number. I have used both IMEI numbers on the Oneplus 2 btw. When I log in to my o2, it shows me my IMEI number and the number linked with it. Can someone please help me in sorting this out, or help me find another way to get 4g on my Oneplus 2.

Cheers

Hussain

I'm not sure if I've got a 4g sim. All I know is my tariff says 4g data, and that when I try to activate it, it can't recognise my IMEI number

It will say 4G on the sim itself if it is. As @MI5 says, you need to check the model number. If it's not the correct model, all this advice is a waste of time.

I've been saying this since first thing this morning but the OP doesn't appear to want to acknowledge that possibility ?
