The UK was waiting for a long time to get Samsung Pay and last week it finally arrived. Last Tuesday Samsung announced all Galaxy smartphones that are supporting the feature can use it in the UK, and now the Gear S2 and Gear S3 join them.
Gear S2 and Gear S3 owners who are also customers of MBNA, Nationwide, Amex or Santander will be able to make payments with Samsung Pay. If you own a Gear S3, your device utilizes MST, and you will have no trouble paying at traditional credit card readers, but the Gear S2 Classic and the Gear S2 Sport are NFC-only, so its either an NFC terminal or no Samsung Pay through your smartwatch at all.
If you dont have the app, you can download it from the Google Play Store or Samsungs in-house Galaxy Apps Store.
