Does the old trick where you claim to be traveling out of country for a week and request a temporary sim unlock not work anymore? I was planning on picking up a T-Mobile variant and going this route through a combination of T-mobile Twitter and Phone support.
I actually got the pixel 7 pro thru T-Mobile and all I did was right away. Asked them. I told him I was an Android developer and I asked. Could I please unlock the phone because when T-Mobile obviously as a lot of you know you have to sim unlock first then you can bootloader unlocked. I explained to them right away. Even though I still owe about $500 on the phone then I needed it done. At first they tried to tell me I had to wait 40 days and pay off my device after I ask him nicely again the same rep she said actually if you'll pay two more device payments equal 48.50 then we can unlock the phone in 48 to 72 hours and they did and now I'm bootloader unlocked

I did something very similar and my Pixel is SIM unlocked through the month of January. At this point, I went into developer settings to enable OEM unlocking but it's greyed out with the message "Connect to the internet or contact your carrier" despite having full conectivity. I think I may need to reset/wipe the phone. I will enter a NON T-Mobile SIM card when I do reset the phone to see if this changes anything

    Hi guys, I'm a longtime member here and developer for Paranoid Android custom rom. While I haven't been active on XDA these days, I did want to share a bit of information about how I unlocked the bootloader on my AT&T Pixel 7 Pro. To my knowledge, carrier-branded Pixel's will not allow bootloader unlocking unless the carrier's requirements are met and a sim unlock is initiated. I had to pay off my Pixel 6 Pro to get it bootloader unlocked in the past so I assume the rules still apply. If anything has changed, feel free to correct me. I just picked up this phone today, and no it is not paid off and still on my AT&T installment plan. This thread does not and will not encourage evading paying off your device installments, while bootloader unlocking does not correlate with sim unlocking, I am not encouraging this glitch/workaround to lead to that discussion.

    THIS IS NOT A GUIDE, this is just an detailed explanation on how I unlocked my bootloader.

    I bought this phone with AT&T knowing the restrictions it had on unlocking the bootloader, but I wanted to take another crack at finding a workaround. My situation is a bit unique but can be comparable to others out there. I started digging through the com.google.android.apps.work.oobconfig apk. The same apk that was removed as a workaround to sim unlock the T-Mobile Pixel 6 Pro. Yes this apk exists on the AT&T variant of the Pixel 7 Pro. So I spent some hours figuring out how it works, and nothing I could get around code wise, but I got came up with an idea. The apk is heavily based on the inserted sim card.

    My Pixel 6 Pro was unlocked through AT&T with that sim inserted. My phone number is now transferred to an eSIM on my iPhone 14 Pro Max, but my old physical sim card was still in my Pixel 6 Pro. Weirdly enough, it picked up the network, there was just no service but the sims ICCD was still registered to AT&T.

    So just for laughs, I took my old sim card out of my Pixel 6 Pro, inserted it into my Pixel 7 Pro and did a factory reset and what do ya know, when I enabled developer settings the OEM unlock option was no longer greyed out. I thought it was probably a bug, so I booted to bootloader and used the fastboot unlock command and the phone unlocked. I still can't believe this worked, I'm not sure if it's an issue with Google's servers or AT&T's servers but I just wanted to share this information to prove that it's definitely possible. If anyone has a similar situation feel free to try it out, even with other carrier's and report back. I attached some photos of proof below. I'm also on A13 (TD1A.220804.031).

    Well you can try the AddAPN app from the Play Store and see if that works.

    It's also interesting to hear another report about nxtgenphone being different. I was seeing people saying that changing the APN from ereseller to nxtgenphone on Red Pocket GSMA switched the data priority to postpaid priority from deprioritized too.
    I have worked in the 3G/LTE/5G home internet industry part time for a little over 6 years now. At&t does some real trickery things based on APN and what exact plan you have. To add to that, it is on a per tower basis most of the time.

    I do a lot of work with Quectel modems and others and do a lot of band locking, tower locking and apn switching to find the best combination for the client and area they are in. But of course all of the modems are unlocked and done with at commands.

    Are you trying to turn off 5G? Because you don't need a new APN for that. Download the app Force LTE Only (4G/5G) from the Play Store. Got through the initial setup (you can skip giving permissions, they're not needed on our phones) and then hit method 2. In preferred network type, change to LTE only (or whatever combo you want minus NR).

    That works kinda of.

    Around here the NXTGENPHONE APN has a higher priority on the network than the enhancednetwork APN. So this does help with connection speeds but during congestion I am in the same boat sadly.

    To elaborated, on enhancednetwork band 66 is the priority band in our area but on NXTGENPHONE band 30 is the priority which is the better band in my area. The best combo here is band 30 CA'd with 66.

    This is only from observations for the last few years or more and talking with field techs in the area. They always give me a disclaimer that it could change at anytime.

    Wondering if someone that got their Att 7 Pro unlocked if they can check and see if they can select a different APN other than enhancedphone.

    I have sort of a problem with mine and Att customer service says it is a problem with the pixel device software and only google can fix it. (about 3 hours total in troubleshooting with them to get that far)

    In my area 5G is being developed and just sucks so it is a known problem and the solution is to set the apn to NXTGENPHONE.

    We'll on my phone when I insert the sim into my locked 7 pro it only gives me the option to select enhancedphone and I cannot add an apn (guessing because of sim lock) I can take that same sim card and put in my wifes s22+ and all of the APN options are available to select. I am curious if this has to do with being sim locked or if it indeed is a software problem with the 7 Pro.

    This happened when I got my Pixel 6 Pro replaced I already had my phone unlocked. When I transferred my sim to the new phones OEM unlock was not grayed out. I just assumed T-Mobile automatically did it since I already had this done on the replaced phone. Sadly this was not the case with this 7 Pro. I sure was excited when I saw this post though.
    I should've added, the moment I unboxed the phone I took the sim card out before booting it for the first time in case it writes to some un-wipable partition. Idk if that's confirmed to play a part in it working
