After several contacts (6) I was always told that there was no AUTHORITY and they did not want to give me a proper contact number. Bought 6 wearables, 2 tablets and now recently (10-09-2021) samsungs watch 4 bluethooth. Very disappointed that after only three days there is no possibility to exchange the watch for a more expensive model (Samsung watch 4 classic LTE). No after sales service apparently. my review will also help to make your choice in the future.
