Just upgraded to the Nokia 6.1 2018 which I bought from below.https://www.amazon.com/Nokia-TA-1068-Unlocked-International-Warranty/dp/B07BVDG8P1/ref=sr_1_4?s=wireless&ie=UTF8&qid=1528141923&sr=1-4&keywords=Nokia+6.1&dpID=41cuid7I6UL&preST=_SY300_QL70_&dpSrc=srch#customerReviews
I configured the sim card settings, all works, txt, mms, calls, internet except it shows a H+ or sometimes 3G next to the cellular. I know I should be getting LTE as I just taken out the Sim card from my previous android phone and I get excellent signal even indoors. Tried going outdoors with the Nokia but it's not a signal issue.
I saw network settings that allow you to manually select 4G, which it's elected, but still no 4G.
This is the unlocked GSM I international version from Amazon, others in the Amazon FAQ did say it works with AT&T / Cricket, hence why I bought it.
Any suggestions, I'm at a standstill.
