Re: iPhone 7 UNV still says LOCKED.. SIM NOT SUPPORTED.

Its not gonna work using verizon sim because the iphone 7 is already locked to tmobile. I have the same problem like you i used tmobile sim to activate the iphone 7. I'ved asked my brother in law to send me a verizon sim it doesnt work.  I called apple support and explain what happen and the senior advisor put me on hold so he can talk to the t mobile i was asked what t mobile number i used to activate the iphone and the serial number/ IMEI number and he told me i have to wait 24 hours they will send the procedure thru email. So my advice to you is call apple support and let them talk to the t mobile.

Re: iPhone 7 UNV still says LOCKED.. SIM NOT SUPPORTED.

I got the same problem . I called Apple and they said they cant do much in this but advised me to do factory reset but it did not work but then I put one old At&T sim and it did work and the phone activated too but soon I removed that sim and put back my Indian sim it says SIM authentication required. I did factory reset and put that SIM back but still the same ... I had only one SIM in India that is AT&T ... I dont know weather I made mistake putting At&T sim and I should have put Vorizone SIM which I dont have here ... I dont know what to do now .... got stuck ... please help me if some got any other solution ....

By activating to At&t your phone is now locked to them, so now you should request to unlock your phone
AT&T Unlock your device - https://www.att.com/deviceunlock/#/
I hope it works for you! goodluck

Re: iPhone 7 UNV still says LOCKED.. SIM NOT SUPPORTED.

After alot of search and reading i concluded that you are tied to the policy of the carrier you activate your phone to(At&t in your case), so i doubt verizon would make difference right now, but obviously nobody really understand what they did to the phones even apple( in my experience ) so if you have got a verizon sim card in your hand give it a try!

Re: iPhone 7 UNV still says LOCKED.. SIM NOT SUPPORTED.

I did sent request to Att and they gave me this anser " Dear Sir, Thank you for contacting about unlocking your Apple iPhone 7 A1660 device.

We're unable to approve your request because the IMEI number provided doesn't match a device that's currently on the AT&T network.

To make sure you have the correct information, recheck the IMEI number by dialing *#06# or check the device settings." my IMEI no is correct ... I had straight talk SIM last time when I went to USA and in that sim kit they give three different nano SIM and the one I used to activate my Iphone was written as For At&T locked phone or any GSM so I m asuming that was AT&T but I m not sure

Re: iPhone 7 UNV still says LOCKED.. SIM NOT SUPPORTED.

Same problem but I solved like Adriano:

1- Buy in ebay (USA ) a VERIZON sim for iphone activation ( used o new but must say for activation), then you have to wait 20 days until the courrier send your package.

2- Then, put the verizon sim, activate the iphone

3- Restore your backup if you have a previous iphone

4- Then when everything in the iphone 7 is working ...

5- Replace the Verizon SIM with your local SIM

6- FINISH and working.

Re: iPhone 7 UNV still says LOCKED.. SIM NOT SUPPORTED.

I bought an iPhone 7+ from Best Buy as SIM Free (Universal) during my travel to US. Here in Brazil, after I noticed my local SIM Card did not work, I read some messages in forums saing I would activate it with a SIM Card from a US Carrier. So, I inserted my T-Mobile prepaid SIM to activate it, but it seems T-Mobile locked my iPhone. I am trying to unlock it since 20th november. First, T-Mobile told me it should show usage to request the unlock. I am using my device for 15 days, sending text messages and making calls, but still no usage. Today, T-Mobile told me that it will not work because I bought my device at Best Buy and T-Mobile will not able to make a request to unlock my IMEI as my device was not bought at T-Mobile Store. The problem is that Apple told me that my IMEI is locked by T-Mobile and only T-Mobile can unlock my device. What can I do?

Re: iPhone 7 UNV still says LOCKED.. SIM NOT SUPPORTED.

This only work at FIRST activation.
If you unlocked with other than Verizon, be sure that you will have to contact the carrier to use another sim
