No signal when using Verizon SIM in unlocked AT&T V30 - LG V30 Questions & Answers

I have an AT&T V30 that I paid off and SIM unlocked with the code from AT&T. When I pop my activated Verizon SIM in there, the phone just keeps searching for a signal, even though I'm in an area with good Verizon coverage.
I have a second AT&T V30 that I unlocked and flashed the Verizon V30 firmware, and that one works just fine, so I bet I can do that on this phone to get things working. I'd love to avoid having to wipe the phone though.
Any thoughts?

Not only thoughts but facts.
The AT&T H931 does NOT have Verizon LTE band 13. It also does NOT have CDMA which Verizon still uses -- at least for now. (Verizon is dropping CDMA end of 2019.)

You must not be in an area where Verizon uses LTE bands 2 & 4, but primarily LTE band 13? You also can't drop down to CDMA, because you don't have that.
You should Frankenstein convert your phone to either open market carrier unlocked US998 or to VS996 to get the necessary Verizon bands. You've done it before so you know yes, it will wipe your phone.

Hah, well facts are acceptable too.
Thanks for the info, ChazzMatt! For some reason I thought I could use the bands even while on the AT&T stock firmware, but this makes sense.

what i don t like about this website, if i set an adresss in france, they simply keep the same price but change it in euro, wich is like 25% price up!
Did you guys already check whether the frequency bands from the South Korean version work in Europe?
I checked the supported frequency bands of the three South Korean versions (please find them below) but, up to now, I didn't check whether they're good for Europe.

Korean version seems to lack 800MHz LTE and 3G band, which is widely used by many operators in Europe.
there is the 850 mhz
What band are missing here??? http://www.ebay.com/itm/New-Unlocke...647596?hash=item33ab4350ac:g:qVYAAOSwl9BWIz8j
I compared the frequencies used in Germany, the United Kingdom and Italy (link: http://www.frequencycheck.com/countries/germany) to all LG V10 models and found all models to be compatible with the frequencies used in Germany, the United Kingdom and Italy.

It might be easier to just ask the guy what exact LG V10 F600 model it is and then to compare the frequency bands of the model (choose a model: http://www.frequencycheck.com/devices/lg-v10) compared to the one used in your country (choose a country: http://www.frequencycheck.com/countries).

I believe 800MHz and 850MHz are different bands.
European carriers use 800MHz LTE Band 20 and it does not seem to be supported by V10.
Pls correct me if I am wrong.
the question has been asked to my operator, and it seems there are no issue:

T-Mobile LG V30 or V30+ Dual Sim

I can't find a for sure answer about this, but dual sim is make or break for me. In interested in the current bogo T-Mobile is offering. We use the kickback feature on lines in our dual sim phones and only use the data on the free lines we have so we get $10/mo back using a dual sim phone.

That thread is not talking about if the T-Mobile version of this phone has dual SIM. It's saying the India version isn't working on T-Mobile.

T-Mobile USA sells the regular V30+, not the DS dual SIM model.
The only dual SIM LG V30/V30+ is the H930DS (which is a V30+).
No North American carrier has the dual SIM model. Even the open market LG US998 V30+ is not dual SIM.
I assumed you meant you wanted to buy the H930DS (V30+) variant to use on T-Mobile USA -- which is what those other people tried to do.

Further to what ChazzMatt said, maybe this will help explain it:
Per gsmarena:

DS models (no Band 2*, AWS Band 4*, Band 5 (usually AT&T), Band 12*, Band 66*, Band 71*):

*current T-mobile Band usage not available on current DS models (though it could be just as simple as flashing the T-mobile software radio though you would need root/bootloader unlock which the DS models are purported not to have) as the DS models usually do not have Band 66 or Band 71 (these are the bands that T-mobile has expanded their LTE network with currently)

Thanks guys! That's a bummer.
US carriers never sell dual SIM phones. They'd rather have you buy two phones

Consumer Cellular No Service

I am unable to get service from my provider. I entered the correct apn settings. I even went through customer support. They couldn't do anything about it. We even tried to select a mobile network under mobile data manually and automatically. It was unable to connect to the network. My model is LG V30 H930. If someone could help me out that would be great. Thanks.

Consumer cellular appears to use at&t and tmobile. Your phone does not support the majority of the bands used by at&t or tmobile. Consider getting the US based version of the v30 us998 or the tmobile or at&t unlocked varriants.

Consumer Cellular uses CDMA. You need US998 or North America variant converted to US998.
You bought a European phone.

US Cellular and Consumer Cellular are two different carriers. Consumer Cellular is GSM based but I guess H930 doesn't have compatible bands. I bought this unit for custom ROM compatibility.

Sorry. Reading too fast. Yeah, Consumer Cellular is an MVNO that uses other real carriers. Still, the H930 is a European phone that may not have all the bands you need.
Any V30/V30+ except for (former) H931/H933 can run AOSP custom ROMs. You should have gotten one of the North America variants which can be converted to US998.

T-Mobile LG V60 US Variant LTE Bands

Hi guys,
Can someone confirm that the US T-Mobile variant of the LG V60 is able to support international LTE Bands such as 3,7 and 20? The information on T-Mobile website is not confirming this.
Link: https://www.t-mobile.com/cell-phone/lg-v60-thinq-5g-dual-screen
I know for a fact that AT&T is usually to avoid as there is no possibility to receive updates without an activated sim card despite the fact that it is explicitly mentioning support for these bands.
Link: https://www.att.com/buy/phones/lg-v60-thinq-5g-128gb-classy-blue.html?offerid=5200006
Verizon variant seems also supporting these LTE bands
