Pick up the unlocked Exynos powered Samsung Galaxy S9/S9+ with dual SIM support from eBay
Both handsets support GSM carriers only, which means that Verizon and Sprint subscribers should just pass this by. The price of the Galaxy S9 (SM-G9600) is $709.99 with financing available that could allow you to pay as low as $34 a month over 24 months. The larger Galaxy S9+ will set you back $819.99 with installment plans starting as low as $39/month over 24 months.
The seller has a 99.3% positive feedback score and as we write this, he has sold 188 Galaxy S9 units and 369 Galaxy S9+ models. Thus, limited versions of both phones are available. If you don't care whether your new Samsung flagship is equipped with the Exynos 9810 chipset or the Snapdragon 845 mobile platform, and support for dual SIM doesn't matter to you, there are better deals available with the four major U.S. carriers.
