Will this phone work with the new Spectrum Mobile plans? I know their list is smaller than AT&T or Verizon but I believe they use Verizon towers.
Asked by: John
Spectrum does use Verizon, but cable companies are very particular. While the phone does have the correct CDMA technology, you should check with Spectrum to be sure. We cannot guarantee compatibility.

Does anyone know if this phone works with Sprint? Any issues activating it on Sprint?
Asked by: Devon H.
Yes, I've used this phone on Sprint for 9 months with no problems, both domestically and roaming internationally. Note that the S8 uses a different LTE SIM card than most phones though. My local Sprint store did not have it in stock and we had to have one delivered from a different store.

HelloTrying to buy an unlocked version of the Samsung Galaxy S8. I don't know the difference between the 3 versions offered here in different prices - N.American Variant/International Variant/International Dual Variant. I want to use it with my cricket SIM card in it. Which one should I get? Which one should I not get?Thanks
Asked by: Samu T.
The North American variant offers the most frequencies and will work best with all US carriers, even Sprint and Verizon. The others are GSM only, and are missing one critical frequency that T-Mobile uses. The North American variant is factory unlocked and has Samsung US support and Samsung warranty.The others have no Samsung US support and may not receive updates. They do have a one year limited B&H warranty. The dual SIM version allows you to have two phone numbers, two different accounts, but you cannot use them both at the same time. The North American variant is the best choice if you'll be using this mainly in the US, but it is also fully unlocked for use in other places.
