Sim not supported for iPhone 6s Plus

[Raoul High]

Hello everyone, I just bought a second hand iPhone 6s Plus and it shows sim not supported.
Please help me sort this out. I am T-Mobile and I guess the phone should be at&t.
Thank you

The phone is probably not unlocked for T-Mobile. Did you test it with an ATT sim?

It also appears to have the iCloud Activation Lock on it which you cannot remove without the previous owner's assistance.

Hey thanks you guys for all the assistance. I haven't yet try an at&t SIM card. But will do it as soon as I get one.

How possible is it to unlock it if I can get to the previous owner. Is there any other way for me to unlock it?

Also if I were to switch from T-Mobile to at&t will I be able to use the iPhone?

Thank you for all your responses

If you can contact the previous owner, he/she can remove the device from their iCloud account to deactivate the activation lock. There is no work around-without previous owner, the phone is unusable.

AT&T would have to unlock the phone before it could be used on T-Mobile's network. It should work if you switch to AT&T, but it must be removed from the previous owner's iCloud account first.

ALC thank you so much for the vital information. I actually call AT&T to find out about the phone and they directed me to att.com/deviceunlock . I entered the IMEI of the phone to check the unlock status. Waiting to hear from them after two days. Will let you guys know the outcome.
Thank you once again

You're welcome.
Good luck with AT&T. The previous owner still must remove it from their iCloud account before you can use it, even if AT&T unlocks it from their network. Hope it all works out.

Hey you all. I went to AT&T and I bought a new SIM card and put in the phone everything works perfect. The phone was actually locked with their carrier and I had to buy a new SIM card to try it while waiting to switch my personal number from T-Mobile to AT&T.
But I want to ask you a question, can this phone be unlocked for any carrier? If yes please do let me know how to go about it or where to do it.
Thank you...

Yes only if its not on contract or financing is paid off. It can be done here. https://forums.imore.com/e?link=htt...tt.com%2Fdeviceunlock%2F%23%2F&token=xXXVFUVk
