Your eSIM picks between these networks on its own. If you see bars and nothing loads, you can pick one by hand.
Your Greenland eSIM runs on one network: TELE Greenland. Other local networks won't carry your data: if you see signal bars and nothing loads, turn off automatic network selection (iPhone: Settings → Cellular → your eSIM → Network Selection; Android: Settings → Network & internet → SIMs → your eSIM) and pick TELE Greenland by hand.
