The Nokia 6 (2018) is now more widely available in the United States. So far, it was only offered by Walmart, but that changes now as other major retailers including Amazon and B&H have started stocking it.
The device is listed on the website of both retailers, although only B&H listing says it’s in stock. Pricing remains the same at around $270. A quick look at Walmart’s website also reveals ‘out of stock’ status. So B&H is currently the only option if you’re planning to purchase the phone.
