[LG V30 Questions & Answers] FuKuRoKu:
I just got my V30+ unlocked from B&H Photo after they dropped the price to $775. I love the phone so far, but getting it registered has been a pain in the butt. I'm posting my story here in case other people are going through the same thing.

Cliffs: If you are registering a V30+ on AT&T on an existing account, I'd suggest NOT telling AT&T your new IMEI. Just move the old SIM over or ask for a new one but don't tell them you got a new phone.

If you are registering for the 2nd Year Promise and your IMEI is "incorrect," you will need to email your invoice (showing the IMEI and purchase date) to	support@lgv30promise.com.

Long story: No 4G LTE on AT&T

After got the V30+, I took it to my local AT&T store to get a new nano SIM card, my old Galaxy S5 had a Micro SIM. The guy registered it for me and put in the APN settings. However, he couldn't get any data to come through, not even 3G or 4G. The guy said my IMEI wasn't being recognized by AT&T. He messed around for about 20 min, then finally said he changed the IMEI number in my account to a different phone (not sure what phone) and then after restarting the phone got 4G. I left the store, then realized I still had no LTE, but the store was closing so I decided to wait and see. I double checked to make sure the APN was correct and the network mode was set to "LTE/GMS/UMTS" and not "Global"

The next day I still had no LTE so I went to a different AT&T store and the guy checked my APN settings again and updated the IMEI in my account back to the V30+. 4G was still working with no LTE after rebooting. He said he added some "code" to my account and told me to wait 30 min to see if the LTE starts working (I have no idea what he actually did). Of course it didn't work so he told me to call tech support.

After about 30 minutes on the phone waiting, the tech support person told me my V30+ wasn't compatible with AT&T LTE and that there was nothing else they could do since I bought it unlocked. :mad:

I called LG tech support just to see what they'd say and of course they said it was my carrier's fault and that the phone should work on LTE.

After that I did some more research online, I found some information for a similar LTE/IMEI issue on the OnePlus 5T. Since I'm new here, I can't post a link but you can just Google "oneplus 5T no AT&T LTE" and it's the first result.

After reading that and a few other forum threads, it made sense. I checked my AT&T account and it wasn't showing a device name for my line, it just said "Device" instead of the model of phone. I put the new SIM back in my Galaxy S5 and my S5 didn't have LTE either (it did before I started all this). So with this info, I went back to the AT&T store and told the guy (different one again) I wanted to switch the IMEI in my account to my S5 (then after I leave, I'd put the SIM in my V30). However, he told me the phone on my line was already set to my S5....contrary to what I saw on my account page. So i explained the whole story to him and he decided to try updating my IMEI again, and of course still no LTE. Then manager came over and then tried updating the IMEI a 2nd time, when it didn't work he then said I was probably getting LTE but that a lot of the new phones don't say "LTE" in the status bar anymore. I knew that was bull crap, so I pulled up the network status that showed I was on HSPA. So then he scrolled around on his tableau for a few seconds...and then all of a sudden I glanced back at the phone and it had the LTE symbol.

In the end, I have don't know what fixed the issue, the 2 guys at the AT&T store said they didn't do anything special, they just tried adding my IMEI again. I suspect maybe someone at AT&T needed time to confirm my IMEI or something and add it to their database, when my LTE finally started working it was almost exactly 24 hours after I first registered it.

Registering for the 2nd Year Promise:

I have a 15 digit IMEI for my unlocked U998U. I tried registering for the 2nd Year Promise but the page was telling me my IMEI was incorrect. I even tried dropped the last digit and it didn't work. I called the customer support number, (888) 959-5175 and the woman told me that my IMEI wasn't in their system yet. She told me to email them my invoice (that shows my IMEI) and they would add my IMEI manually so that I can register it.
