LTE not working with LG G5 but HSPA works

I have a recently activated LG G5 that will only work in HSPA mode. No LTE. When I activated the phone I had the Mobile network "Network mode" set to "Global". The other two network modes are LTE/CDMA and LTE/GSM/UMTS. The phone works when set to Global or LTE/GSM/UMTS but doesn't work when set to LTE/CDMA. Also if the phone is set to LTE/GSM/UMTS I have settings for "Network submode" and a submenu that I can search for networks and it scans for networking. I can find Koodo LTE/CDMA network by searching but when I select it it fails. It also has a select automatically option that seems to work. Data was not working initially because the APN fields were all blank. I figured out how to set this myself as the rep at the store/kiosk was totally useless and didn't understand why data wasn't working. How do I get LTE working on an LG G5?

Was your phone from Koodo initially? If it wasn't, make sure APN settings is correct: https://www.koodomobile.com/help/setting-data-your-non-koodo-phone
You might have to reset network settings and try to restart the phone before doing so

With Koodo, you choose network mode to : GSM/WCDMA/LTE auto

If you acquired it from a third party, check your handset against www.willmyphonework.net

Sounds like it could be a Verizon (or other) CDMA from the US. CDMA has largely been phased out in Canada.

Thanks for the replies.

It's an LG G5 RS988 unlocked including the bootloader.
I don't have a network mode called GSM/WCDMA/LTE.

I have three choices, Global, LTE/CDMA and LTE/GSM/UTMS.

I got data working with the correct APN settings.

The problem I have is the phone seems to only connect with HSPA not LTE.

I read somewhere that another user with similar issues did a factory reset and LTE started working. When I do the factory reset should I leave the SIM in the phone? BTW is it possible the SIM could be 4G only and not support LTE?

And hey thanks for the help.

I don't think it makes a difference, but you will have to insert it anyway, so just leave it there. LTE SIM has been in canada for almost 10 years, I don't think your SIM was not LTE compatible.

I really want to get this phone working 100% because I bought two LG G5 RS988s. I got them for $200USD each. Smoking deal if you ask me and they have no screen bleed or any of the issues with the modules mating to the phone body with gaps etc. Also none of the antenna bands show on the back body of the phone as reviewers have complained. It's a fantastic phone IMO and was manufactured in Aug of this year.

Good for you. I think the recent G5 has been remade with better quality control. Koodo also had deal on G5 before through wowmoble, themobileshop. Normally it was $360 on Tab medium and $200-300 gift cards.

I order my LG G5 RS988s from B & H Photo Video in NYC.

Checkout the specs of your local tower

http://www.ertyu.org/steven_nikkel/cancellsites.html

Even though your phone may support the LTE frequencies, there's a chance your local tower only does the 3G 850/1900 and not LTE band 4 even though the advertised coverage map indicates LTE. If your signal is marginal in an LTE area, it's not unusual to see the connection drift from 3G to LTE and back again, or not to see the LTE at all.

Download the Signal Strength app from the Playstore. If you always see no service at all on the LTE band while the tower supports it, there's probably a handset issue.

I stood right underneath a Telus LTE tower and it was still using HSPA. What particular "signal strength" app are you referring to?
